BSNL Broadband is a broadband internet service from state owned BSNL in India. during Past few weeks many Bsnl Broadband customers are complaining that they can’t open some sites like Google.com,Microsoft.com. MSN.com, Hotmail.com but can connect to mail.com,orkut.com. the sites which are not opening are random – it can be any site which does not open.If you a similar problem and can’t open some sites then read on……
There are mainly two Reasons to this Problem:-
- Bad DNS: Bsnl’s DNS sometimes due to overload fails to resolve queries. sometimes this is a temporary problem. if it occurs often then change to third party DNS server like Opendns. changing DNS server is very simple process, there is no software to install. you just need to specify IP address of alternate DNS servers. Opendns also has other features like filtering of adult sites etc. detailed instructions on how to setup can be found on Opendns website.
- Large MTU: MTU stands for Maximum transmission Unit. it is max size of each data packet which travels across a Internet. each interface has it own MTU value. Larger MTU ensures bandwidth efficiency but it can also choke interfaces. if you have problems with your network a conservative MTU value of 1454 is recommended.to change MTU. The third party Dr. TCP software can be used to change the MTU setting.
- Download this tiny utility from here. choose exe file type
- Run the utility you just downloaded.
- In the Adapter Settings, select the Ethernet driver and adapter used to connect with BSNL broadband.
- In the MTU box, type the 1454.
- Click in any other box, without changing the data there.
- Click Save.
- Click Exit.
- Restart the computer.
Hopefully you be able to solve your network problems. Enjoy High-speed enabled Internet!!

my prob was wid the MTUs. i used the Dr TCP n changed it, but that didnt work.
i use MTNL Triband (Mumbai). so the ISP has provided me with a Router. I went to the Router Configuration Page (default: 192.168.1.1) n changed the MTU there n that did the trick..

Hi,
You are fabulous. After trying different options suggested online and following up with BSNL, they suggested I purchase a new broadband modem to resolve the issue. constant follow up with BSNL offices with no avail, i had decided on cancelling my broadband connection. I came across the solution on your blog and it resolved the issue. Thanks again.
Thanks a lot. Changed MTU in the router home page and it works after that.
Thanks, hurrah finally i fixed the problem. i changed it from 1484 to 1454.

Bharani
Thank you so much ! you have done wonderful service for layman like me.
thanks gaurish ……. it is a pain for me …… for some time …. MTU is the issue … except that i did everything … but nothing worked ….
thanks …. for the tips ….. but can you possibly tell me whats the MTU issue it is … just for curiosity
@sourav
In simple terms, issue is that somtimes size of internet packets which carry data exceed the capacity supported by network pipe. hence, we reduce the size of that packet.
