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 (192.168.0.1) but not my isp's modem(192.168.15.1). 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
ping -c 3 8.8.8.8 shows 100% packet loss

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 but can't browse. If I connect it directly to the isp modem via ethernet cable it starts working fine.

Connection Information shows:

Interface: 802.11 wifi (wlan0)
driver: ath9k
security: wpa/wpa2
speed: 150mb/s

ip: 192.168.0.106
broadcast: 192.168.0.255
subnet:255.255.255.0
default route: 192.168.0.1
primary dns: 192.168.15.1

i have restarted the router and modem many times. Rebooted the LiveUSB many times.

I know that Ubuntu +1 questions are frowned upon, but this I believe is a fair exception. Currently I have 2 systems running Ubuntu 12.10, and one of them has a Pentium M that doesn't support PAE (strange I know, but true). This has meant in the past that I had to rely on a custom iso to install… >>> More
