MTNL Low MTU - Need Help!

[DJDrunk]

I got a new MTNL connection and They gave me Sterlite SAM 300AX
In my router the TCP MTU setting is 1492 and TCP MSS is set to 0 (default)

I noticed that my broadband speeds are not great and MSN does not work.
When I try to ping My router or public DG, it's only connecting at 1272

Pinging 192.168.1.1 with 1273 bytes of data:
Packet needs to be fragmented but DF set.

Test on SpeedGuide Says
SpeedGuide.net :: The Broadband Guide

MTU = 1300
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.

MSS = 1260
MSS is not optimized for broadband. Consider increasing your MTU value.

Default TCP Receive Window (RWIN) = 65535

Was your connection previously working properly?? If then do not change the settings as per the Speedguide.

msn.com is still not working with their default dns !

if you are using vista then try this tweak :

it made my response time very fast and using with open dns is charm!
open dns of 4.2.2.3 & 208.67.220.220

I always take second open dns order for better response !
