Question

Posted

Today I installed drivers for my Broadcom wifi card - it was working under Fedora, but after restart under both Fedora and Win7 there are neither wireless nor wired connections available, despite both wireless and ethernet card detectable by the system.
I read sth on google that fedora sometimes burns broadcom wifi adapters. But maybe firmware is just messed up?

I followed this tutorial -> http://forums.fedoraforum.org/showthread.php?t=239922 , laptop is Dell Inspiron 1545 '09 with Dell Wireless 1397 on Broadcom BCM4312 chipset.
In the tree below I got the solution to install version 4 firmware, so I did. WiFi worked until first restart, now I can't even get any packages from the internet because of not working net adapters.
