Hi
Been on i burst for a week now and it is running well. I get a 90 to 100 % signal off the Wonderboom tower. Just a few issues that need clarification.
When the modem is idle (UTC) the signal will drop to 80% but immediately jumps to 100 when a request is sent thru it (Clicking on a link or something).
Speed:
Below is the data used to calculate your download speed:

* Download time: 5.14 seconds
* Size of file: 500 KiloBytes
* Estimated line speed: 793.8 (kilobits/second)
* Estimated line speed: 97.3 (kiloBytes/second)

When d/loading a file, the throughput varies and depending from where obviously - one thing that I find disturbing is that the signal will drop to 0% for about a second and then jump up again to 100%. Depending on from where the d/load is made, I get speeds of from 400 to 900 kbps (it fluctuates).
MTU is 1352; RWIN 64288; Win scaling YES; Time stamping NO; Acks YES; MTU Disc YES; Black hole NO;Max dup acks 2; TTL64.
When idle, the Frame error rate is 0% but during transfers, this also jumps up at stages and then back to 0. Also when going to a web site, there is sometimes a delay before the modem sends the request.
I am not complaining about the speed and access as I find this muuuch better obviously than ISDN just want to find out if this is normal - I have no external antennae.

Support:
Last Friday after receiving the modem I phoned for them to activate the account after I installed it. Phone answered on 4th ring - was told to give 5min for the account to go thru. Was activated in 3min. Then after about 1hr got a call from Cape Town to find out if everything is alright.
On Sunday, found e-mail and access to the bandwidth usage monitor not working yet and sent an e-mail via the web site. Received a e-mail back after abt 3hrs (thats when I checked) to say e-mail is fixed and I have access to the bandwidth monitor etc. So no horribles as described here experienced yet - maybe they concentrating on their cust services a bit more now.

Should not have problem of being called an ábuser'as I have the iGo package which cuts off after cap unless more bandwidth purchased. Recon will use in the vicinity of 1 GIG p/m at current levels.

Hi adsl3g. Yup, that sounds about par for the course. If you want to bypass the delay you mentioned, do a search on the forum for the ping workaround - if you can afford the bandwidth.

Keep us informed should anything change. Otherwise, good luck. Some of us get iBurst, some get iBust.

What is this ping workaround you speak of?

 

[Raithlin]

Set up a constant ping - I have a app that pings the gateway every 5 seconds. The signal strength stays at maximum (active link), and no delay is experienced. I think Slimothy can be credited with discovering this (although I stand under correction), way back in the middle ages.

Would UOTrace do the trick?

I believe the credit goes to TheLoneGunman.

Thanks, GC. I was too lazy to search for it myself.

Kudos, LG.

Not too clued up on TCP settings..
Would changing the RWIN to higher no like 255555 (like seburns) make any change to latency, ping times etc. My MTU is 1352 according to the posts in these forums.

..and Gatecrasher why is yr MTU so high - I get fragmentation if anything other than 1352 or is it the tower you on?

ping 196.30.31.100 -t

I get ping around the region of 100

Actually the ping "solution" found it's roots in the old Mywireless forums ... but then who's keeping score

Also when going to a web site, there is sometimes a delay before the modem sends the request.

I dont have problems with signal strenght (allways 100% -> -62 to -67 dB) and I still have the web response pauses.

It is my belief then main problem is the slap/lazy web proxy server(s) WBS run. Seem like they just use open source Squid running on PC based hardware. While there's nothing wrong with squid, its performance is a good as the techie optimising it, and this becomes a ballache past a certain scaling.

Thats why all decent ISPs invest in purpose built cache servers from companies like NetApp, which are designed/optimised for extreme volume caching (proprietary real-time OS & propriety storage architectures + file systems).

Just WBS being cheapskate.

ping 196.30.31.100 -t

I get ping around the region of 100

Where or what is this address, cause I get Minimum = 62ms, Maximum = 875ms, Average = 274ms...

My signal strength (Northcliff...) is around -66db.

Just a note that i bought the external antenna and... WOW. The speed is like i'm strapped to a Boeing! And my modem always had full lights on it - so that doesnt mean squat. Probably getting a lot of bounce in my signal with the modem alone so that slowed everything down and increased timeouts.
