HOWTO: Get RTL8187B (ID: 8197) Working. Step by Step

[afeasfaerw23231233]

I am using ndiswrapper for realtek 8187L (ID:8187). The native driver (rtl8187) doesn't work for me. Fixing the rate (e.g. 1M) would only reduce the frequency of disconnection. Also, in my system the native driver cannot auto-negotiate the rate as the signal is weaken. After I have install ndiswrapper with win98 driver the connection is perfect even it's in extremly high trafic.

p.s. I am using Intrepid i686

I experienced the same problems described in this thread.
Updating http://wiki.ubuntuusers.de/Linux_Wireless and activating channel11-13 fixed the problem for me on Intrepid(amd64) 2.6.27-11, with RTL8187B usb wlan.

"new, much cleaner, rate control API "
That is in the new Kernel, 2.6.29
Basically this means (In theory) that all the problems with the wireless card will "disappear".

There is a way of updating all the wireless drivers in any Ubuntu release (Inculding the driver for the Wireless Card ) to the lastest version (From Kernel 2.6.29)

This is how:

Download the package here: http://wireless.kernel.org/download/...ss-2.6.tar.bz2

And extract it.

Then:
(In Terminal)

cd /home/username/Desktop/compact-wireless etc

make

sudo make install

Reboot!

Hope it fixes the problems.
(If wireless doesn't work at first, just, in termainl, run this command:

sudo modprobe rtl8187

Then wireless should work.
(If it does, stick that code (without sudo) in /etc/rc.local)

My Friend followed your instructions (by himself - I'm well impressed) - and it fixed it perfectly - so many thanks for your help.

Also, sounds like good news that it is fixed in 9.04.

Thank you for the hint.
I had done it before and it seemed to work. But this time on another laptop, (same model as mine) it did not.

Here is the last lines of make command:

Does it make any sense to anyone out there?

it doesnt make any sense to me i came accross your post cause i googled the same term i just downloaded a 5 day older tar ball and that worked must be a bug that they need to get out

http://www.orbit-lab.org/kernel/comp...-04-13.tar.bz2

this is the one i downloaded that built fine

[sosostris]

Thx for posting the link anyway.
I also cannot compile the package for the last ~10days.
I am pretty new to ubuntu but could it be the kernel 2.6.27-11 is just no longer supported? You can actually make the build work by defining the constant by yourself. Nevertheless it got me in trouble later and the package totally broke my wlan.


Now I installed the 04-08 version and it works like a charm. It also solves the well known issue of losing your wlan connection when doing to much upload (eg torrent).

Thanks. I will try that one.

I installed the latest compat-wireless drivers, and it doesn't make much difference. I'm still downloading at 125 KB/s although I have a 30 Mb connection.

I tried installing linux-backports-modules-jaunty, but I get the following error after I do sudo modprobe rtl8187 :

FATAL: Error inserting rtl8187 (/lib/modules/2.6.28-11-generic/kernel/drivers/net/wireless/rtl8187.ko): Unknown symbol in module, or unknown parameter (see dmesg)

This is what dmesg says :

After adding this : options cfg80211 ieee80211_regdom="EU" to /etc/modprobe.d/options, i was able to use the backported module.

However the problem stays the same.

I was able to make my rtl8187b work in ubuntu 8.04 with this driver http://rapidshare.com/files/21484241...07.2008.tar.gz

In ubuntu 9.04 the wireless card is recogniced and it connects to my router (at least it says its connected) but i don't have internet connection or ping response for the router.

Any ideas?

Soultion found !! Installing the new driver release from Realtek (2009). You can download it from here http://ubuntuforums.org/attachment.p...8&d=1240801314
