Since March 20 I am unable to open most of the websites such as yahoo, indiatimes, msn. What is strange is all the google websites is accessible such as gmail, google, orkut , google news. On checking with BSNL, they changed the DNS server but without any success . The same problem is even with the laptop. I have reconfigured the modem but the problem still persists.
Any assistance is welcome and appreciated

Edit the PVC with VPI /VCI =0/35
Click next twice
Change the MTU seen below Username & password

also try MTU values like 1454 and 1492 .. change these values in your windows machine.. if possible get a LIVE CD of ubuntu and try connecting

shawn600

Tried 1454 and 1492. the problem still persists.
Any other DNS Settings which needs to be changes?


Found this command to check optimum MTU on some other forum.

need to check the below
ping -f -L [packet size] [website]

denharsh

Generally the issue can be because of DNS...
try using open DNS
That will be helpful for u

PROBLEM WA3002-G1
Tried Open dns and MTU change. Still some web sites not accessed.


Checked with the (*same?)Modem and Laptop on another BSNL connection @ bsnl office, was able to connect and open all the websites

Now very difficult to pinpoint the fault.
Ignore all below. Expand above result.
PARA TWO:
try TCP/IP optimizer from speedguide.net
or
Dr TCP .
DRTCP: How do I use it, & what are all these settings?

@ Essbee YOU ROCK!!!!!!!!!!!:t humbup:

I downloaded TCP/IP optimizer from speedguide.net and set MTU as 1444.

Able to open all the websites with an improved Speed

sanjdar

what does TCP/IP optimiser do? can i do the TCP/IP settings manually, without the optimiser?

essbebe

.1.Mention your modem/model number.

2.The problem you face. Like some web sites not opening,slow speed etc.

3.Download the application and see the advice given.
Then further clarifications possible.

4or if you want consult another "specialist" DR TCP
for the answers!
DRTCP: How do I use it, & what are all these settings?

5. from Post No 4.

sanjdar

I want to know the function of TCP optimiser, and how to tackle the problem without installing any software.

1) UTStarcom WA3002 G1 Type2

2) Hotmail not opening

3) If i don't want to install 3rd party software?

because I use both OS, XP & Leopard, I can install TCP optimiser on XP but what about Apple? that's why I would like to set-up manually....

SpeedGuide.net :: Images

You can see what parameters are changed.
Do it for Windows and MacOS.

superprash2003

the most important change is the MTU change..
