Problem : My internet connection get disconnected constantly for a while, but it get resolved by itself after a while.
Situation : This happens after I upgrade my Ubuntu OS 13.10 to 14.04 and this problem only appear when I get connected to my office wifi. (I don't get this trouble at my home wifi)
Clue : When I do a ping, I found this message when the internet connection is down:
ping: sendmsg: No buffer space available
Could anybody help me to resolve this problem? This problem is really annoying for me.
