After upgrading to Ubuntu 13.10 from 13.04 my wireless card connects to the router, the router is connected to internet (I am sure about that) but still no internet access for my laptop!
I am using Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter.
iwconfig gives me:
lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11abg ESSID:"asteras" Mode:Managed Frequency:2.462 GHz Access Point: 80:1F:02:8D:4E:8C Bit Rate=72 Mb/s Tx-Power=200 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=70/70 Signal level=-38 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Not blocked by anything, I use wl proprietary driver and I also used brmcsmac but it didn't work at all, I couldn't even connect to a wireless network.
