I have installed 12.04.1 on Dell Latitude E6510 At work I could able connect to WiFi and it is OK At home I use DSL WiFi modem router which works fine and I can connect thru Windows, Android phone etc. But Ubuntu doesn't even see SSID name. Only "my" SSID name :( I can see others
03:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
My wifi settings are WPA/WPA2 PSK
