Sick speed on PtaWUG

I've been on the PtaWUG for a couple of months now and have found it to be a blast. My connection was down since some time this afternoon, though, (this does not happen often) and just came back on a few minutes ago.

So anyways, the gamers must have also been offline because when I came back up I started downloading a torrent and managed to download an entire 700MB file in 3 minutes 12 seconds! That's more than 7 MegaBYTES per second sustained! I was dumbstruck! This just shows you what this WiFi technology is capable of.

This made me think: How much of a slowdown are we going to see as more and more people join the WUG? I'm sure that the clever guys like ProtzKrog must have given this subject much thought but how do you guys monitor congestion on the WUG's backbone?

Can you download using torrents on the network? I take it, it's localized (only on PTAWUG) torrents, and not internet torrents.
 
One quick question

I looked at the KML file from WUG and I am just like three houses of the red line. I have no colour on my house location under the JWUG, does this mean that I wont be able to connect to the network?



Thanks
 
I was surprised by the amount of feedback that this thread has generated, including a number of private messages from people asking for advice on how to join so I guess that in a small way I've contributed to the growth of the WUG. :D

However, it would be remiss of me not to relate my experiences of the last week or so, which also highlights the negative aspect of any free technology.

As I've stated before, my first two months-odd on the WUG were fantastic with me regularly seeing sustained download rates around the 500KB to 700KB per second range. Unfortunately all of this came to an end about a week ago when all of a sudden my speeds decreased dramatically. I am now lucky to see 50KB per second, which is slower than my ADSL connection.

At first I thought that this was temporary but after a few days and a reboot of mt routerboard I realised that something more serious was wrong. The first thing I did was to check my signal strength but I found this to be just as before - around -66dB, which is considered to be a good signal.

My next step was to consult the WUG's online documentation which contains a section devoted to optimising wireless performance. Basically this revolves around activating something called WMM and another thing called "adaptive noise immunity". Unfortunately neither of these did the trick and I was still stuck at a far slower speed than a was used to.

I was reluctant to take the required next step - asking for advice on the IRC - because I've been flamed quite severely by a few members when I initially required advice on setting up my connection and acquiring an IP address even though I made an effort to be polite and not to ask stupid questions.

So anyways, I took a deep breath and asked for advice on the IRC. Again I got a few "don't ask stupid questions, noob" replies but thankfully one guy (thanks, Wab!) took the time to assist me via PM and he was indeed very helpful. He assisted me in doing a traceroute and basically I was able to establish that my bottleneck was at the highsite that I connect to. My ping times to the highsite iteself were more than 1000ms while all the other hops were quick.

This same guy was also able to ascertain that more than 20 guys connect to the sector on the highsite that I'm linked to and that this might be the cause of my trouble. What does confuse me is that this degradation occurred very suddenly and, as I've stated for, I was seeing tremendous speeds before.

Unfortunately being a layman I am unable to explain this in technical terms but I would guess that one or more users connecting to the same sector on the highsite are saturating all the available bandwidth because if this was merely a result of a steady increase in new users signing up then one would expect the degradation to be more gradual, not so?

The end result is that I'm now sitting with a connection that is, if anything, slightly slower than my 512kbps ADSL and I've got no recourse to anybody seeing that the entire network is maintained by guys that do this without any compensation and merely as an act of goodwill. I cannot phone or email anybody and say "Hi, please would you log a ticket to fix my slow connection". I guess I'll have to go and speak to the guy that runs the highsite to see if he won't do me a favour and investigate this for me. I don't know if this would be possible but I'd be prepared to cover the cost of any hardware that he might require to upgrade his highsite. On the other hand I might just live with it. 50KB/sec without any caps and at no cost whatsoever is not too bad I guess...

Apologies for the long post but I thought that I should not only point out the advantages of free technology but also the pitfalls.
 
So anyways, the gamers must have also been offline because when I came back up I started downloading a torrent and managed to download an entire 700MB file in 3 minutes 12 seconds! That's more than 7 MegaBYTES per second sustained!

According to my calculations, 700MB/192seconds = 3.6MB/s

Unless the link is running dual nstreme turbo or mimo, I would highly doubt 7MB/s is an achievable speed.

This same guy was also able to ascertain that more than 20 guys connect to the sector on the highsite that I'm linked to and that this might be the cause of my trouble. What does confuse me is that this degradation occurred very suddenly and, as I've stated for, I was seeing tremendous speeds before.

No offense to whoever manages that site but really... 20 people on one sector... talk about over-kill, lol

Again I got a few "don't ask stupid questions, noob" replies

I might not know the circumstances revolving around that situation, but whom ever said that, if indeed that is what they said, should be ashamed of themselves and just stfu. You do find some guys who think they are the "main men" and unfortunately there is nothing you can do about it. Hopefully karma will come back to them and mysteriously cut their pole down.

StrongTurd, what is your nick on IRC, where do you connect ?

Connecting to a sector that already has 20 people on is not a good idea, rather get on the roof and scan to see if you pick up any other highsites, even if your signal is worse, if there are less people on, speeds will be better.
We try to spread the load evenly among the highsites.

You are free to make a page on the wiki in Highsite Planning detailing the problems on the site, possible upgrades, costs, etc. Then we investigate, and upgrade if possible.

Remember that this is a wireless users group, even if you are a layman, you are here to learn. You are one of the guys that maintain the network as a act of goodwill, and the main guy that is going to fix your connection is you. I knew 0 about wifi when I first started wugging, but learnt a lot through fixing, trying, talking.
Also remember that PTAWUG is ONE network, all highsites are managed by PTAWUG, speak to a admin to have a look as well. Also speak to other users that connect to the same sector.
Check the wug calendar for highsite missions in your area and go with to learn some practical skills.

Check your CCQ - signal quality as well.

Best bet would be to move to another highsite.

About a year ago we lost one of our main highsites, that had 6 backbone links and connecting 20 people to the sectors. The network was practically broken for a month and a bit while we had to look for, fund and put up a new tower. Everyone had to help to fix the network again. Where dit we discuss everything and made plans - IRC.
 
Hello Protz. I'd rather PM you my nick as I'd prefer to remain anonymous on a public forum but I do connect to Waverley (WL) sector S. I'm 2.3km away from the highsite. As I've said before I'll be happy to assist financially with upgrading that highsites. I'm unable to connect to Riviera (large palm tree) but I CAN see Waverley Sector W at about -70dB.
 
OK sharp, pm me then. Ja, Saturday when we put in the new PC for Riveria francoistk told me that their yard stretches up a long way up the mountain, it's about 2km to the west of Waverley highsite. Just waiting for him to take LOS pics then we can plan to put up a site there. There is also a spare sector for WL that must be put up as well as fixing the link from WL to DW.

Remeber that a week ago the Riveria site went off, PC died. Thats why the speeds dropped so much. RR provides links through to Hermon in the north and Wonderboom which links to Die Wilgers, as well as link to Mountain View. Something is not lekker with the replacement PC, so speeds are not as it was yet. All this was indicated in the IRC topic as well as the wug calendar as well as the Riveria highsite page as well as the To Do List on the wiki - put your name up to help with the install.

If you can see SectorW, connect to it and get your IP's moved over by an admin. easy peasy.

wifi does not just STOP in the middle of nowhere because we indicated the approximate direction and width of the antenna beam on google earth.

10 to 15 degrees to the side of the beam you will still have good signal, some dudes even connect to the back of the beam from a short distance away.

if you are in front of the beam you will have signal as long as you have LOS.
 
PTAWUG - Rules

Hi,

Maybe some perspective would be in order:

We have:

51 High sites
113 Backbone Links
114 PTMP interfaces (Sectors and omnis)
480+ Users

We have:

about 25 admins (less than 10 active atm)

Based on the above we have about:

680m of LMR cable on high sites
340 radios

==========================

All of this administered and maintained by people in their spare time.
Our sites have a very, very good uptime ratio which I would love to compare to the likes of iBurst stations.

Then after administering and maintaining all of these high sites, admins are expected to be polite and patient to those users who chose not to get involved and not read all the wonderful pages and guides and information available.

Our Riviera site had a few problems, which we promptly sorted out this weekend, by walking up the mountain and replacing what is needed.

I don't want you to think that I'm flaming you, but I do want the chance to just put things in perspective.

By my estimate, we shift about at least 1700mb/s on the network at any moment!!

PTAWUG is a success story, and a network where you can share and learn.

Rather be part of the solution, choose to not moan.

Hi there ...

Let me introduce my self first my nickname is webster on the ptawug (NW_Sector). I joined the wug few weeks ago even tho i didnt know anything about the wug until 2 months ago.

I spent alot of time (about 2-3 weeks) checking and researching the http://www.wug.za.net/ website. Then i`ve decided to buy the wug kit, and since i bought that kit it has been very exiting for me to be a part of such a large community of ppl.

In any case i wanted to say a few word to the people out there witch are considering to join or just joined the wug.

1. Be very careful when you check your Line Of Site (LOS) on wug.za.net. Because you might be in the area witch is not covered and you going to end with expensive useless equipment.

2. Buy the wug kit form the shops that are recommended in the wiki. Believe me this is the only way you gonna be connected properly, and beside that scoop and miro are donating part of these money for further expansion of the wug.

3. Read the Wiki 2-3 times before start assembling the wug kit (as protzkrog said earlier on this is half of the fun.)

4. Before putting up brackets on the wall and making holes, just get on top of the roof with your assembled wug kit and check to witch highsite you are going to be able to connect.

5. After you install the wug kit and set up your router board (RB) according to the wiki you should be able to connect to the preferred highsite. Then join the IRC (you have to connect to internet). I dont have adsl at home or any other source of internet at this moment so i used my cellphone to connect and ask for an ip address. Read the wiki how to connect and ask for an ip address from admin in IRC. Sometimes there wont be admin available because everybody have their own personal lives and their own personal reasons to not be in IRC. But believe me it worth the waiting.

6. After you set up the routing and the interfaces in your RB with the ip addresses witch has been given to you from the admin, open your browser and type in for ptawug http://172.20.1.1 and for jawug http://172.16.1.1 . These are the internal wikis for the different wugs in Gauteng.

7. READ THE INTERNAL WIKI VERY CAREFULLY. Everything is written there (what exactly you can do on the wug).

8. Some advices for ptawug users:

- Read the News and the recent changes page on the internal wiki before start asking questions in IRC like why my connection is slow and so on and so on. Every day there is changes happening to the ptawug and this is the only way to keep on track.

- Read the topic on the #ptawug channel in IRC. Also helps a lot if there is changes to be done by the users side. For instance the other day one of the highsites was upgraded with enstreme option and the users connected to that highsite had to change the set up of their RB.

9. Happy wuging everybody. I hope i was clear enough with my post!

Hi there ...

If if you cannot find what your looking for on the Wiki, create a new wiki page and get the info to share with the rest of the comunity.

On another point, the RB433 can do 3 links, so link to a second HS.
Second link can be used for redundancy or a shorter/faster route.
WUG is a mesh network, the more links you do the better the network becomes. so, mesh mesh mesh ! :D

If everyone is linked to someone else, you won't need to depend on the HS's.
 
@ LouisP: I'm sorry but the sugar coating towards the end of your post fails to hide your vindictive attitude. This is EXACTLY what I was referring to when I mentioned the hostility that I experienced from some quarters on the IRC. How one could label me as "part of the problem", a "moaner" and "uninvolved" after reading my previous post is beyond me. The little encore form Ryder does not help either.

In case I did not make myself quite clear, let me rephrase, but before I do, please be absolutely assured that I do not intend this as negative criticism (moaning, as you put it), but rather as a factual account of my personal experience. Ok?

Firstly, I found the setup and configuration documentation to be seriously lacking. I'll be the first to admit that this might well be due to the fact that I'm a complete moron and that I didn't have even the vaguest idea what a something like a routerboard or a pigtail aerial was when I first got my kit. In fact, even now I've still only got a very rudimentary working knowledge of everything involved. Be that as it may, I found myself on numerous occasions during the installation process to be completely stuck and no amount of reading and re-reading of any of the documentation could get me past certain points in the installation procedure.

I want to emphasise here that I NEVER simply jumped on the IRC and started firing off lots of questions before making absolutely sure that I could not solve my problems by making a detailed study of all of the documentation. In other words, whenever I asked for advice on the IRC this was as a last resort and only when I've exhausted all other options.

So anyways, almost every time that I asked for advice on the IRC I was immediately referred back to the documentation and was told "not to ask stupid questions before doing my homework". When I then explained to the users that I've already done all the reading that I could and that this did not help, the response was along the lines of "Well, if you don't want to listen then go and do whatever you please. Why do we have to keep repeating the same stuff over and over to noobs who do not READ?!"

I have to stress that every time this happened there were also people that absolutely went out of their way to help me at all hours of the day. In fact, I found that the vast majority of users were most helpful and friendly. Protzkrog was one such a guy. This guy is absolutely a class act and I can only speak of him (and a number of other guys that helped me) with the highest of praise. It was just that the vocal minority spoiled the experience for me. Even then, I was soon up and running and was a happy camper with a very, very fast connection.

Now let me address your accusation that I'm uninvolved: Has the thought occurred to you that maybe I'm not a card carrying member of MENSA and that perhaps I know less than nothing about wireless IP networks and that asking me to "get involved" in stuff like configuring the network and assisting with the setup of highsites would be the same as asking Julius Malema to land a Boeing 747?

Alas, the only "involvement" that I might offer that could in any way be seen as helpful would be to offer financial support. I DID mention this in my previous post, by the way. What I've decided to do was to start paying my own self imposed "monthly subscription" towards the upkeep of the network. I have yet to figure out how to actually go about this but the plan is to make a monthly financial contribution to the WUG via EFT.

I'm getting paid on the first of the month, by the way, and I'll be ready to start paying my "subscription" at the weekend. For obvious reasons I'm not comfortable divulging on a public forum the exact amount that I've got in mind but suffice to say that for someone like myself who doesn't earn much and who has a wife and kids to feed this is a substantial amount that I could definitely have made good use of elsewhere. PM me if you want details. I'll be willing to sign a debit order too. So much for me not being involved.

I trust that this rather verbose explanation has proved to you that I'd much prefer to be "part of the solution" than the opposite and that I'm merely looking for a solution to my speed problem.

Lastly, thanks for the excellent advice that I've received on this thread form spiderz, jannysoft, protz and acidrain in particular. I'm leaving early tomorrow morning for a business trip but I'll be digesting all of your suggestions when I get back this weekend. Much appreciated.
 
Hey, I was impressed by all the tech-stuff! They seem to have more links than I do at home! :)

There is a wiki at 172.20.1.1, make a new page, and put in the stuff that you struggled with with better descriptions/explanations/pictures/etc. then we can put it on ptawug.co.za. This an community effort.

On http://www.ptawug.co.za/content_list_11 there is a table with a picture and description of each item contained in the kit.

Now let me address your accusation that I'm uninvolved: Has the thought occurred to you that maybe I'm not a card carrying member of MENSA and that perhaps I know less than nothing about wireless IP networks and that asking me to "get involved" in stuff like configuring the network and assisting with the setup of highsites would be the same as asking Julius Malema to land a Boeing 747?
One has to start somewhere, first you go with on a highsite mission, help carry the equipment up, fasten antennas, align atennas, connect pigtails, connect LMR, etc.

Alas, the only "involvement" that I might offer that could in any way be seen as helpful would be to offer financial support. I DID mention this in my previous post, by the way. What I've decided to do was to start paying my own self imposed "monthly subscription" towards the upkeep of the network. I have yet to figure out how to actually go about this but the plan is to make a monthly financial contribution to the WUG via EFT.
http://www.ptawug.co.za/content_list_29 - these are the projects currently running. There is no way to pay a monthly "fee" to keep you connection up and running. Especially in the moot we struggle with people are just MIA and do not make an effort to physically help on highsites. The second sector for WL is there, it just needs to be put up. Money won't fix the problem, getting up and doing something will.


I trust that this rather verbose explanation has proved to you that I'd much prefer to be "part of the solution" than the opposite and that I'm merely looking for a solution to my speed problem.
Help install the second sector on Waverley and get the WL-DW link going.

Suggestion to improve the documentation is always appreciated. Especially from the view point of a new user.The documentation has improved a lot from the previous version (thanks to the pictures). Make suggestion on the wiki or in irc. (wiki is probably better)

As regard to the IRC, you'll always have a few idijts blowing off steam there. It's a public IRC, it happens, at least their is more helpful ppl available there and you get an answer almost immediately. :D

Oh, and don't be afraid to ask question, you'll never learn if you don't ask. The trick is to ask the correct questions... :D

I'm sorry but my attitude is not vindictive. I've helped more than a 100 users connect, spending hours with some of them. So maybe I'm sometimes abrupt or direct or to the point. But I'm not vindictive. I was merely stating the facts just like you!

I have also personally spend hours working on WL's configuration. I've also spend plenty of time on the documentation.

Instead of moaning about how bad the documentation is, why don't you just improve it?

Instead of moaning about your speeds, why don't you just improve it?

I would say, without our current documentation it would require someone spending between 1 and 4 hours on average to help someone connect.
so lets say 2 hours (allthough I think it is more). That means it would have required almost a 1000 man hours at least to help everyone get connected.

So, out of respect for everyones time, we ask people to take their time and read the documentation, then if they get stuck, I would be the first to help.
BTW. our guides are good!!

Louis, I should apologise if I created the impression that your not inconsiderable efforts are not appreciated. On the contrary, I am much in debt to users like yourself who took the time out to help me at various times. For that I am very thankful and I thought I made that quite clear in my previous post. I AM IN NO WAY BELITTLING YOUR EFFORTS!

However, why you persist with calling me a "moaner" is beyond me. How do you expect me to "fix my problem myself" when my grasp of wireless technology is, if anything, downright dangerous? Likewise, how do you expect me to rewrite the documentation when I barely understand the difference between wi-fi and hi-fi? How can labeling me as "part of the problem" in any way be justified as merely "stating the facts"?

But enough of that. I'm beginning to sound like a stuck record. Allow me to put it on record that I apologise profusely for sounding less than appreciative of all your efforts. That was honestly not the intention. I am indeed very thankful. The same goes for everybody else that helped me at various stages.

So how do I go forward with this? I've just gone through all of the posts with excellent advice that I've received on this thread. It would appear that my speed problem is indeed related to congestion on the Waverley South sector. If I understand Protzkrog correctly then there is indeed equipment available to rectify this but somebody just needs to actually install it. Right? So how do I offer my services?

Protz, I've just visited the project page that you linked to earlier (http://www.ptawug.co.za/content_list_29) but I don't see Waverley upgrades being listed as a project. Do I need to add it to this page myself? If not, then how do I initiate such a project? As I've stated before, I'll be more than happy to contribute financially if this would help.

Alternatively, how much work is involved in moving myself over from the South Sector to the West sector. To be honest I am extremely reluctant to start messing around with stuff like IP addresses and persistent routes (whatever that might be) if not absolutely necessary because I'd rather not scratch where it doesn't itch.

@ Spiderz: I'm intrigued by your suggestion to "mesh" by adding links to more highsites. How does this improve the network? Does it mean that IP packets will be able to pass through my routerboard on its way somewhere else, thus expanding the "backbone" (for lack of a better word) of the WUG, in a small way benefiting everybody?
