OK i have now jumped up and down enough....

I have been solidly connected for the last 4 days. Speed is flying.
Things seem to be improving. True there have been mail problems, but hey, it is still pre launch. Our reason for been in this forum is to be an aid to others who are still as yet undecided about iburst. The speed truely kicks adsl's butt.

For you guys having a few problems i hope you have set your mtu to 1352. Fast and stable.

Also there are now new names at their call centre. This means they are not just raising ant.s but growing their staff to meet our larger and growing needs.

You still want to bitch...

Get a new pc or move if you have a bad signal.

Iburst is realy performing.

Great job guys. You are kicking Sucktech's butt good and solid. About time some good competition hit our broadband market.

where are you located?

MTU must be set to 1392 for all iBursters, less than that and your connection is not optimized & will be slower, higher than that & your packets will be fragmented & slower throughput.

I have tried 1392.... SLOWER DOWNLOADS.....]


Leave me alone on 1352..

It is what the help desk recommends as well.

Call if you dont believe me.

The Helpdesk recommended 1392 to me.

Regardless with my MTU set at 1392 I cannot access certain sites, including this one It also ran dramatically slower.

I think the key is to the the ping test and discover your optimum MTU through a bit of trial & error. I find that at 1392 I cannot d/l faster than 120Kb/s but when I set my MTU to 1024 I can reach speeds of 130KB/s. (ofcourse all multithreaded)

I am still very sceptical about the entire MTU issue, however I will continue to fiddle until I find something I am happy with, although I must admit that if I leave it at default I experience no degrade in service at all.

What UT do you have, if it's a UTD how is it attached, what OS are you using, if Windoze what's your latency like to 196.30.31.100 & what's your RWIN value?

PS: I double checked just recently to see if MTU of 1392 was still correct, and it was, so unless WBS have gone & changed their official MTU without informing us, it is still 1392 for a PPPoE connection - perhaps you misheard the helpdesk, or the helpdesk people don't know what they are talking about...

....it is still 1392 for a PPPoE connection - perhaps you misheard the helpdesk, or the helpdesk people don't know what they are talking about...

Agreed.... or there is confussion over MTU and MSS. With MTU of 1392, the MSS is 1352. I use a RWIN of 18x1352 = 24336.

If you have Path MTU discovery "on" you will automatically get MTU of 1392 via the WBS server, regardless of your MTU setting.

Most default TCP settings work fine because Path MTU discovery defaults to "on."

But, theoretically at least, you can improve data throughput by optimising RWIN to an even multiple of your MSS. The windows default is too small, and can slow you down, particularly because the higher latency of wireless.

But I'm no expert, so...

sexual, glad to see more happy customers joining my team, its been lonley the kast couple weeks

 

[sihen]

We are testing a few MTU's and one that is being tested right now and seems to work the best is 1352

 

[Impressed]

Told you guys 1352 was on the spot.

I am using a UTD on a P4 3.6, 2 gig ram, 21", 750 Gig SATA etc etc

My up time is 16H48M after i restarted my machine to load codecs..

Hope this service can continue at this pace.

Great job.. to all at Iburst

The fact is that it's typical WBS to not inform us of a critical change that affects everyone, also MTU Path Discovery doesn't always work, there stuff like Black Hole Detection & other things you don't want to get into.
