BSNL broadband does not work with Ubuntu 14.04

@vishal Rao - Router name - Teracom - model number TDSL 300W2

The current issue is that I cannot access the net through DHCP but only through static IP.

Hard reset of the router using a pin has been done half a dozen times. But I am not able to configure DHCP. So we went with the option of static IP which works for now.

Yeah I read DHCP doesn't work on both Windows or Linux for you - that sucks - and points to likely DHCP config problem on router admin page side.

Would you mind trying to enable DHCP on the router side and OS and type the output of "dmesg" command here from Ubuntu? (Just to see if some info is there related to DHCP issue in the logs).

@ashwin_d123 in addition to "dmesg" output , can you post screenshots of your router config pages for LAN and "DHCP Server" portions, just to see if any anomalies there?

 

[ashwin_d123]

Dropbox - rout
That is the output of dmesg.

How can I turn on DHCP if I am unable to access the modem settings page ?

How do I access the router config pages for LAN and DHCP ?

 

[vishalrao]

OK so you are able to browse net with static settings but cannot open the router admin page at 192.168.1.1 ?

Can you check your "subnet mask" setting in OS is it 255.255.255.0 or 255.255.0.0 , try one or the other then again opening webpage http://192.168.1.1/ in your browser?

The DHCP or LAN settings should be there under some page titled like "Internet/LAN" or "DHCP server" something like that.

Meanwhile I will look at the dmesg if I can understand anything from it

 

[vishalrao]

Ok - could not figure out anything from the dmesg log

Can you try this - enable DHCP in your OS (change to "Automatic" in IPv4 settings dropdown) - and save it. Then in the console type following command:

sudo service network-manager restart

(I hope this is right version of command for 14.04 OS) and then see if you are able to connect to Internet and also the router's page at 192.168.1.1 ?

 

[ashwin_d123]

I tried that. sudo service network-manager restart after changing OS settings in networking to automatic DHCP.
It tries to get a connection and then disconnects. Frequently it tries and fails.

So I am back to static IP

 

[vishalrao]

Also @ashwin_d123 - when you have working connection in static mode - what is the "Gateway" value set in your config? Try that gateway IP as the modem/router webpage IP?

 

[ashwin_d123]

Gateway value is 192.168.1.1 in Ubuntu right now.

Subnet mask is 255.255.255.0

 

[vishalrao]

Did you try subnet mask (called "netmask" in the settings dialog) either 255.255.0.0 and 255.255.255.0 and also try opening 192.168.1.1 and also whatever is written in the "gateway" section of the OS settings dialog for both settings?
