can you help me with a problem. using IDNET I cannot play or host, AOL using the wireless works Great

IDNET since the 11th February lags out and does not work with TA springs ,
AOL works no problems.

Using IDNET whilst joining other peoples rooms after about 2 minutes I cannot move or order my units, when still in room playing people I see them typing on the screen saying hello tiptop etc I cannot respond due to a time out etc, but I can see my allie still building away!
I,am stuck ? help

IDNET Hosting a game after a couple off minutes all other people including my allie all time out and I,am only the one that can move even though they cannot do anything

With AOL I do not suffer any problems I stated above.

I have tried this since it started above whilst the 2 ISP are on the same GREEN exchange and confirmation that "BT are indicating that the line
is performing correctly" also TA springs is OK as per using the AOL connection?
can somebody help me find out who is to talked to, to solve there problem :-(

Hello!

Whats TA firstly? (a game yes...but that doesent tell us much!)
Try pinging some addresses such as multiplay.co.uk, by opening command prompt via start - all programs - accessories, type ping multiplay.co.uk

From what you've said it looks like a firewall issue thats kicking you/your freinds from a server after a few mins

[siege2]

Nope no firewall in the PCs

only firewall is in the router which correctly forwards port 8452 in / out to port udp / tcp
this same PC and others work  with aol. But not IDNET ?

also tried a old USB adsl modem and also a netgear as well as Belking all work brill whilst playing games withing the UK whilst going out off the country using TA springs using connection with IDNET it happens, not with AOL ?

Can we assume that you have spoken to IDNet Customer Support ?

talked with Simon, Miriam, Andrew about the problem in hand for nearly 2 weeks now, everyone seams stumped..

Iam going to phone up asap to discuss things ! further..

[siege2]

well the good news "so far" having talked to Miriam, I have bieng advised to change the MTU to 1400 and using DRTCP021.exe from this site http://www.dslreports.com/drtcp put the MTU at 1350.

So far after one Afternoon and Evening so far no repeats have happened from what I have experienced from before :-)

Well done Miriam

oh Hurry up with that extra bandwith, PIPE :-)

also whilst browsing found these very informative Webbys for assisting further using MTU etc

ADSL MTU's

WHAT IS MTU

http://www.wcc.net/faq/mtu.htm

1350 seems very low, I tend to find the DSL reports site encourages lower figures than are really needed. I prefer Speedguide here, select Analyzer on the left.

[siege2]

PS
should have being more bold 1400 is the mtu for the router
1350 is the MTU for the PC.

It doesn't matter what the router is set to if Windows is using a smaller figure, and vice versa. The smallest figure controls the size of packet sent (though having a smaller MTU on the router than in Windows will cause local fragmentation and add to your problems.

Of course, for AOL, the MTU should be 1400. It may be, therefore, that your router was set at that, while you were using a larger figure in Windows? That would certainly account for your problems. I'd set the router to 1500, then make any adjustments in Windows.

[siege2]

The figure is greater in the router at 1400
the PC MTU is 1350, although noted what you have said ok,
but yesterday as a test worked brilliantly, no problems I was having over the past weeks have happened again.

Well, if you're feeling adventurous, set the router to 1500 and Windows to 1500, then start pinging the sites you use.

Start with ping <url> -l 1472 -f (that's a lowercase L, not a 1. There must be a space between the l and the figure).

That will cause the site to be pinged with 1472 bytes of data, and the fragmentation flag will be set. If your connection is throttled, you will get a report that the packets were fragmented. If they are, reduce to 1400, if that isn't fragmented, then try 1430, if that is, reduce to 1415, if that isn't, increase to 1422 and so on. Eventually, you will find the largest packet size the system can handle without fragmentation. That's your optimal MTU.

Set Windows MTU to this figure, adjust RWIN to be a multiple, then try the game, if all is well, you'll be obtaining the most from your connection.

OTOH, if you're happy with the speeds you're getting, just leave it as is.
