Thread: Unable to open specific websites! Surprising!!!

I am using BSNL broadband 500C plan for past many years.

Always I have been unable to open specific websites. A small list of them are...

yahoomail.com
hotmail.com
mediafire.com
mathworks.com
etc.

in case of mediafire, just an initial progress bar appear, but no download link appears.

i have tried to open these sites both on my desktop and laptop, on different browsers(chrome, firefox, internet explorer) and different OS(windows xp, windows 7, ubuntu 10,11) but still i am unable to open.

thats why i came to the conclusion that some problem is with my broadband connection.

Someone please help!!! Please , please , please...
Thanks in advance!

Mention modem/router model/make/number.
Check MTU value usually 1500/1492 decrease in steps of 8 and try.
Default 0(1500)
detailed suggestions ( if needed) on feedback.

Try tcp/ip optimizer from http://speedguide.net

1. Change DNS to Google DNS or Open DNS

2. Change the MTU values to 1440, 1450 etc and check.

Modem specs:
Beetel
Product: ADSL2+ CPE
Model Name: Beetel 450 TC1
Month: Nov Year: 2009

Thanks for the reply. will try and let u know shortly...

If nothing works, try Opera Turbo. It can open those sites.

unless MTU parameter is set,
perhaps change of browser may not help, boss.

Opera Turbo works like a proxy. So irrespective of your MTU settings, it will open sites that are even blocked by ISP. Worked in a few other cases.

i have tried to open these sites both on my desktop and laptop, on different browsers(chrome, firefox, internet explorer) and different OS(windows xp, windows 7, ubuntu 10,11) but still i am unable to open.

Result :
MTUDNS change did not help:

Cause:
Common Gateway : Modem/router 450TCI. ???
Check firewall page disable both boxes..

or
How you connect to Internet ?
Using Dialer? 1483 Bridged mode or
PPPoE mode.
Change connection mode to Dialer and try.

try using different browsers or may be there is a temporary disruption
