Problems all day and night with the wireless .
Finally had it working and now upgraded the kernel and nothing at all.
Cant find a wlan0 device.

Ive check in the kernel everything is the same as before.
Except after the upgrade it had deleted my /lib/firmware/rtlwifi/rtl8192cfw.bin
So I placed the firmware back into the correct directory.
Modporbed rtlwifi and rtl8129ce and it still wont appear any ideas what the hell is going on ?

Really starting to grind my gears

Ok fixed but by emergeing linux-firmware but i had to remove radeon-ucode which i need for X.
Any ideas on how to solve this ?

Also still have to keep using iwlist scan to connect to my network this makes no sense at all

Maybe the Madwifi could solve your problem?
It seems it works with even the recalcitrant wireless cards

Err, not only is madwifi completely outdated, it's a driver for Atheros, not Realtek.

@gentoo_newguy: If you haven't noticed by now, linux-firmware includes radeon firmware too.

Ok no problems with that . So the radeon firmware is installed with linux firmware (i didnt no that)
Why does my wifi only connect when i type iwlist scan .
Seems really weird to me.
I cant pull a lease with dhcpcd doesnt matter if i restart the box or anything wpa supplicant doesnt read anything on startup and iwconfig will show wlan0 but with no network attached to it . i can leave it for 1 min or an hour nothing.

The minute i type iwlist scan it connects.
Im happy the wifi is working but dont want to have to type this every time i boot up the machine. and the fact it drops about every hour or so and once again i have to type iwlist scan to connect again.
