I have a quick qwuestion for a odd problem. SO Riser/folken/bob/ anyone...RichPLS? if you have ideas I'm all open (not you wingding, if you do look at this part of the forum anyway...).

I have a LinkSys WRT54GS router. Maybe one month ago I wasnt able to access www.hotmail.com and www.tomshardware.com...a few othersites, like my AV update site, addons.mozilla.com etc.

But all the other web sites worked flawlessly google.com etc.

Now If I remove the linksys from the loop it works 100% all the sites.

I did flash the firmware too the latest, default settings, it doesnt helps. So anyone got ideas as what I should do?

I might add that I can do a nslookup on all the site that dont work and the names get resolved so its not a DNS issues, I get timed out every time!

I heard about modifyed linksys firmware, I'D be willing to try this...Anyhow any input would be appreciated! Thanks guys!

Linksys website attributes this to the MTU being set differently.. 1492 should be the correct setting..

192.168.1.1/filter.htm

enter your password, change the MTU.. I see 2 settings.. they recommend 1492 or 1400.. claiming that should fix it.

Im at 1492 right now!
I will try 1400 when I get home thansk for the info!

And yes I was aware that 1500 can cause odd stuff...Didnt think it would be linked to my problem thks for the info!

And uh you think the registry "hack" to set the MTU lower would help or just te linksys is fine?

Whats odd is that it was working fine before and I havent changed anything...

Edit: I did some readin on the MTU and people complain about getting to the hotmail.com page but not being able to login. I dont even GET to the hotmail.com page, so dont know if its related...
I'll still give it a shot later on...

Windows has it's own MTU but your router has it's own MTU setting too. You'll want these to mesh up. Ethernet standard is 1492, but I want to say that it's different somewhere along the line.

It's based on how much data is transfered.. 1492 being the max size, so if it goes over, the packets get fragmented by the router, which inturn causes the problem.

I'd shoot for 1450 (any number really works, the smaller, the more packets, the higher, the larger the packets, but then it can stress the router). 1450-1470 would be good, since it adds 15 or 18 extra on top of that.

That's about the only thing I could possibly think of that would cause the problem through the router if it's still with default configuration..

Set windows and your router to have the same MTU.. there are programs out there to cover the Windows portion or you can do the reghack.. either way, but the programs tend to be nifty.

Did try to change it on my PC yet, not enuff time, Bt it didnt change anything on my router...
I heard about alernates firmware with more options for the linksys, I'll try to find some...Otherwise it might just be defective.
