http://ubuntuforums.org – I am working with ubuntu (gnome) 10.10 maverick 64 bit on a HP pavilion 2713ca. I have installed the Broadcom sta driver for a BCM4328 wifi driver. After setting wpa security with my password, the wifi network worked for many weeks. However, in the last few days it doe not connect no more. I have tried to reinstall SSID. And I have checked to see if eth1 was still there: root@max-HP-Pavilion-dv2700-Notebook-PC:/home/max# iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11abgn ESSID:"" Mode:Managed Frequency:2.412 GHz (HowTos)
