Problems with Realtek RTL8191SEvA Wireless LAN Controller on Compaq Presario

I've installed Debian Squeeze on a Compaq Presario CQ56, the wireless card is identified as:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8191SEvA Wireless LAN Controller (rev 10)

This is not supported by the kernal, so I downloaded drivers from Realtek, built and installed them.

I can now scan - and my router will show up, but I'm not able to connect to it.

I turned off WPA on the router, but this did not help. I know the
router is OK since I can connect with the same computer using an
alternative OS ;-\

From what I can see this would be consistent with the card beeing able
to receive, but not to transmitt.

So - I'm stuck here, any tips on how to procede from here?

Check the hardware compatibility list before you buy. Now that you have it,
try the Ubuntu forums. What isn't answered there isn't worth answering.

with the first gereration of the RTL8192se i had a problem like you.
Using wicd instead Networkmanager helped.


p.s. In my case (8192) the actual driver works with both.

Excellent advice, thank you!

I was using wicd, but Networkmanager was installed, and presumably
started via udev or some-such. I uninstalled it and now wireless is
working beautifully with wicd.

From the RHEL and Fedora world, NetworkManager is *not* your friend.
It's a fairly complex set if independently managed components which
leave out features of the underlying network configuration tools.
Frankly, I'd rather see it tossed out completely and replaced with
Webmin based components.
