I went to that site (someone suggested somewhere)

And they sell antenna's and amplifiers, would it be possible hooking an amplifier up to your antenna (looks like poynting yagi antenna) and then hooking it up to your modem?

Should be about 40 dbi gain

Whats your opinion?
 
40dbi gain? Damn thats alot...although I would be careful walking in front of its beam - you may lose the ability to have kids [:p]

Whether its a Transmit or Receive amplifier you did not specify, anyhow you would need a RF sniffer and high quality RF changeover switch, unless the amplifier has this built in, but would the costs involved be worth it - I dont think so.

lets assume I get the yagi, my signal strenght is 23%, what signal strenght would I expect with JUST the antenna?

I'd like to have a very stable ping.

BTW, if anyone can answer why I can download/upload through mIRC @ 14kb/s on the 512k package, that would be great as well.

My up speed is about 25k/s (tested it last night upping something to uunet) and download speeds are cruising, might sentech have a throttle on the port 6667 somehow? (or even IS?)
 
noone, a 12 dB yagi will give you about a 10% to 15% improvement.
Your up speeds are 25k - eish you lucky, I've never seen above 12k [:(]
I upload more than I download and everytime I have to disconnect and go back to adsl [V]

Btw, Sentech are not throttling any ports.

hey hey

i get really slow downlds with bittorrents im talking likr 2kbs :( im on 256k with 20% signal i have no idea whats wrong, i download at like 40 on url's . any help would be appreciated :P

noone, if you DCC in IRC it actually establishes a direct connection between yourself and the other person. If that person can't send faster than 16KB/s, then that's all you'll get.

Another thing to look at is the block size and most IRC clients have a setting to enable fast DCC transfers. Both parties must have this setting set.

eg. in BitchX you set block size with /set dcc_block_size 2048 (or whatever works best) and you enable fast dcc transfers with /set dcc_fast on

It is in general advisable to first try a higher gain antenna. It makes the modem receive more signal from the tower (and vice versa) and less of any interference coming from elsewhere. If its a receive amplifier it will amplify any interference you're picking up.

Remember also that with bittorrent your speed is not constant and while the client hops around from sources on the tracker, it does not download. The trackers are overloaded and slow so they dont handle all requests immediately. This would be how it works: you want piece 234 from 192.1.1.1 and also 235 from 192.1.1.2 now the 192.1.1.1 server is full so you are "bounced" to the next one but since the tracker is overloaded you wait say 30 seconds for service. then it sends you to 192.1.1.2 (say) which is also full and you are busy getting piece 235 there already. So the process repeats until you find a slot. During this time your downloads will be slow or stop.

The 2k/sec is probably some guy with 1Mbps sharing over 60 connections or something which means he has many "slots" but his bandwidth is overutilised by the majority of slots. In fact, this will happen for about 5 sources and the total will be 2k/sec. Just wait and wait and it will eventually speed up and hit maximum.

If it is ALWAYS 2k then check your firewall/router/routing software to make sure all the right ports are open.

I'm getting tired of hearing that, these dudes are on 1 meg lines, if I FTP to them and download, I get great speeds. I also tried upload/download from an ADSL buddy of mine close to me, same speed, doesn't go faster, and even goes slower if another download via mIRC starts

Hence why I thought 6667 might be throttled somewhere

Plus, my bittorrents are almost exactly like Drak's, I always upload at 8 kb/s and almost never go above the same speed (spikes alot though, thanks for the bit of info)

So yea, I'll try those DCC commands, hopefully things would speed up a bit.

And yes, I use mIRC (scripted some of my own stuff) to transfer work related files to my home PC, seeing as these bastards won't give me terminal service access via our firewall

bittorrent is pretty useless with firewalls. also DCC is blocked. you can of course try using tunneling software or a SOCKS type firewall.

what speeds do you get with kazaa? One would think if they were going to implement port shaping it would be on kazaa first. Try perhaps, if you havent already, another IRC client, another IRC download server.

Even if the guys have 1Mbps UP then you can still get low speeds here like 10k due to bottlenecks etc. Keep trying different servers. If its a local server ie. work&lt;-&gt;home then it must be some other problem.
If you can, test from another tower also with NO firewalls of any kind. Even if you configure the FW yourself. I'm sorry if I have insulted your intelligence or anything like that [:)]
 
Tried 3 different towers, i'm against using kazaa (use my connection usually for work related stuff, and obviously porn)

I'm not really in the mood to learn another IRC client, although I am pretty sure it won't help much.

Thanks anyway

DCC won't use port 6667, it uses random high ports
6667 is only for the IRCD connection.

Bittorrent tries to be fair when it comes to sharing with others. If you're limited to 8KB/s upload, then the download is only gonna try for 8KB/s download, and will go higher every now and then. Go check the bittorrent FAQ. This means, people on asynchronous connections like ADSL and IPWireless will not get full speed most of the time.

Port shaping will have almost zero affect on Kazaa because of the way the protocol works.

I'm currently on a torrent, download at about 10-13 kb/s, up at around 20kb/s???

I'm on the 128k package, which leads me to believe these speeds are not too accurate.
 
So if you are on 128k then what is your <i>average</i> download speed on bittorrent. It may spike above 15k but its just a spike.. on avergae it cant (in theory) go above 8k/sec. Can you just make sure for us and if you do get higher speeds.. keep very very quiet and make sure you are only paying R650[:D]
 
Actually on Average the top d/l should be around 10-15KB/s since the true absolute top of 128K is 16KB/s :) so 8KB/s is actually a 64K or half the speed but 10-13KB/s is pritty damn good :)

Yeah. I was mixed up. I meant 8k upload and 15k download speed. With 8k up its pretty cool if bittorrent goes above 8k regularly.
