Hi,
I am using a Bluetooth dongle in my Laptop to access internet by connecting
to my Desktop which in turn is connected to the internet through a ADSL
modem.
However, I am facing a strange problem after getting connected to the
internet, which is that I am able to open only few sites in my browser, in
fact I can only open google sites such as : gmail ,google, gtalk etc. Trying
to open any other site results in no action. The browser keeps sending
packets but their is no reply. As such the page is blank with no visible
page and ultimately the page times out.

Although I am able to use TCP/IP applications but the problem is with web
pages. I have tried using all sorts of browsers but of no use. The problem
persists in all of them.

I somehow found on the net that it could be the problem of MTU size set in
the registry. Therefore I tried to lower down my MTU size to 1452, and tested
that it is the maximum packet size I can afford on the bluetooth adapter.
However, still after changing the MTU size in the registry I am unable to
open all the other websites.
Only google.com, and its related links are opening. There is no security
level problem or moderation or firewall of any kind which is hindering the
sites, because when I directly connect to the internet using ethernet adapter
I can straightaway open the sites.

Shishir,

So when you lowered MTU to 1452, what test results convinced you to stop there?
There's nothing magical about MTU that says "stop there", as minimum value in
all problem cases.

What MTU references have you read, anyway?

And have you tried opening any websites by IP address?
