Many ppl with NIB-I or NIB-II connection are complaining about they are not able to connect to some sites.sometimes it is google,micro$haft etc.

So the Solution is to change the MTU(Maximum Transmission Unit) to 1454 from 1500 or 1492.

In GNU/Linux , you can easily change by editing /etc/ppp/options file or /etc/ppp/peers/dsl-provider to add MTU value.

First try as root ,"ifconfig ppp0 down && ifconfig ppp0 up mtu 1454" to see the change!I was not able to access youtube and all(very slow).now it changed :)

In window$ ,I have no idea.apart from in cmd , "ipconfig /ALL" will show those values :p

but I saw this thread ,in broadbandforum :

^this is the solution for winblow$ users. :)

Doesnt the MTU value change for people depending upon their connectivity. The best bet would be to find the MTU value ourselves and set it in the router.

Windows 2000/XP users:

Go to Start/ Programs/ Accessories/ Command Prompt and type the following:

ping -f -l 1472 www.google.com
(That is a dash lower case "L," not a dash "1." Also note the spaces in between the sections.)

Linux users:

ping -s 1472 www.google.com

OS X users:

ping -D -s 1472 www.google.com

Linux and OS X commands are case sensitive.

Press Enter. Then reduce 1472 by 10 until you no longer get the "packet needs to be fragmented" error message. Then increase by 1 until you are 1 less away from getting the "packet need to be fragmented" message again.

Add 28 more to this (since you specified ping packet size, not including IP/ICMP header of 28 bytes), and this is your MaxMTU.

Hope this helps :)

even I thought like this!but 1454 is the value that works for now.it is some problem with routing with NIB ?

Legen-wait for it-dary!
I dont know, yesterday there were problems, I couldnt access PirateBay and Demonoid, and today its fine. Yesterday I was messing with MTU too, but I couldnt get any value which worked for those sites. So just gave it up, then today I reset it to 1500 and they start working... Must be some problem with NIB.

I am 100% sure that some problem with NIB(routing?).with MTU=1454 it is a good value.
1492 aint enough :)
