[Rtl-wifi-devel] Realtek RTL8187B stopped working

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

Hello there,

I have Ubuntu 13.10 Server running 3.11 kernel, I also have two USB Wireless adapters as follows:
Adapter 1: Realtek RTL8187B chipset https://www.thinkpenguin.com/gnu-lin...-g-usb-adapter
Adapter 2: AR7010+AR9280 chipsets https://www.thinkpenguin.com/gnu-lin...nux-tpe-nusbdb
They claim that they work out of the box and they did, however, Adapter 2 had some limitations on frequency use
So, I recompiled backports 3.15 source files after doing some manipulations to get a more opened driver, these manipulations were only for Atheros drivers
Now, Adapter 1 stopped working, I tested the same adapter on another computer and it works fine
The adapter doesn't even show up in lshw -C network
I looked at the module in /lib/modules and the module is still there, apparently it wasn't modified recently
Kindly look at the following codes

hosam@Robin-05:~$ sudo modprobe rtl8187
ERROR: could not insert 'rtl8187': Invalid argument

hosam@Robin-05:~$ sudo insmod /lib/modules/3.11.0-12-generic/kernel/drivers/net/wireless/rtl818x/rtl8187/rtl8187.ko
Error: could not insert module /lib/modules/3.11.0-12-generic/kernel/drivers/net/wireless/rtl818x/rtl8187/rtl8187.ko: Invalid parameters

Do you have any suggestions?
Thank you

Welcome to the beauty of open source….
If it ain’t working use KGDB to debug it, fix it yourself.

That’s the real beauty of a long time dead driver…

Tells me you should recompile your driver and kernel…
FWIW.

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!
