view story

http://askubuntu.com – I'm running ubuntu 12.10 liveUSB on a lenovo b570e. It has an atheros wifi card that connects with my home network but I can't browse AT ALL. My network is multiple clients --> router --> isp modem --> Internet I can ping my router ( but not my isp's modem( I have 3 other computers connected to the same router that are working fine (infact i'm posting from one) ping -c 3 google.com unknown host google.com I think its some networking issue. I tried directly connecting it to the router via ethernet cable but same issue. It gets an ip, shows LAN connected (HowTos)
