WIFI broken after kernel RPM update

[Zoltan Hoppar]

Yes, I have.

In my HP Probook 4515s have broadcom either.
Follow my steps, and you never again loose your wifi after a kernel update.

1. http://linuxwireless.org/en/users/Drivers/b43?highlight=%28broadcom%29
2. Search for "If you are using the b43 driver from 3.2 kernel or
newer:" text and execute the steps after it in terminal one by one.
Exporting the variable will make your machine immune to loosing after
updates your wifi.
3. Check the blacklist files, you have to use the b43 module, and ssb
too to get higher speed. ('Locate blacklist' command will show the
file). If your wifi sign has no colors, just wire squares - it means
that you use it just in basic mode, with 24 Mbit max peak. (if you add
ssb, you receive 36)
4. Install rfkill package too, to check that your real wifi switch
state - sometimes it stucks in OFF state, or such. "rfkill list"
command will tell you, and you - and with other parameters, you can
solve with it. When you removed the block, you have to always restart
- then continue.
5. Check the result always with dmesg, and 'lspci -vnn -d 14e4:' to
know what happens.

HTH, if you have more questions, drop me an mail.
