I am using Ubuntu 13.04 and sometimes I'm unable to connect to Internet. After adding a DSL connection in my network connection preferences, DSL connection1 isn't visible anymore. When trying to connect using the pppoeconf command, the command is completeyed but when checking the connection using plog I get:

Aug 14 21:49:38 vijay pppd[887]: Compression disabled by peer.
Aug 14 21:49:38 vijay pppd[887]: Could not determine local IP address
Aug 14 21:49:38 vijay pppd[887]: Connect time 0.1 minutes.
Aug 14 21:49:38 vijay pppd[887]: Sent 118 bytes, received 138 bytes.
Aug 14 21:49:38 vijay pppd[887]: Connection terminated

After trying 5 to 6 time able to connect to internet. Does anyone know what's going on?
