I have a Laptop Dell Mini 910 Inspirion Wireless card: Wireless 802.11g Mini Card 32-bit Itel Atom Processor, N270 512K cashe, 1.60GHZ, 533MHZ FSB
Did a 14.04.01 upgrade and do not have Wi-Fi. Same thing happened on previous upgrade to 12.03.3 LTS. Solution was to get 2480236-Broadcom Firmware.tar.gz. I tried this and NOTHING.
Troubleshooting thus far:
Type of card: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] {rev 01}
I can see the empty (no signal) Wi-Fi ICON.
ran command:nm-tool
State: disconnected Device: eth0 Type:r8169 state: unavailable default: no HW Address: 00:21:70:D7:EB:cc Capabilities: Carrier detect: yes Wired Properties Carrier: off
ran command: iwconfig
lo no wireless extensions. eth0 no wireless extensions.
Anyhelp would be appreciated.
Thanks.
