Re: [Rtl-wifi-devel] Realtek RTL8187B stopped working

[Hosam H. <h.h...@gm...>]

Recompiling the kernel or installing a new one would not work.
Because I would recompile Adapter’s 2 driver and that would probably cause the same conflict again.
I recompiled backports 3.15 source files with my custom settings, but this time for both chipsets.
I needed to use “make defconfig-wifi” because RTL8187B is not listed in “make menuconfig” or compiled when using “make defconfig-rtlwifi”
After using “make defconfig-wifi” I manipulated my settings and now everything works
Thank you!

Eng. Hosam Hittini
