Realtek Wireless Drops Out Shortly after Activation

Postby robthorley on Sun Mar 10, 2013 1:46 pm

Hi All,
I have installed Linux Mint 14 Cinnamon on my Samsung N210. The Wireless is a Realtek RTL8192SE (I think).
It connects so that I can log into email, other sites, but then it drops out after two or three minutes.
Ethernet connection works fine (as evidenced by this note :) ).

Can anyone talk me through how to fix this? I'm a complete noob, so would need step by step guidance.
I've tried downloading the driver from the Realtek website but for some reason cannot d/l the file (?).
If I was able to do that, I'd have to look into compiling the drivers, but not sure what I already have in place...

Here's my system info:

Linux Mint is funded by ads and donations.

Well so, I have overcome the first hurdle. The reason I could not download the driver from Realtek's site was because I was using Chromium. So switched to Firefox and Hey Presto! I now have the software.
But I've not been able to compile it - will post screenshots in a bit (4 hrs or so, after work)

Okay, this is the output from the 'make' command:

I also checked my wireless drivers through Menu > Preferences > Software Sources > Additional Drivers and "No Proprietary Drivers are in use".

I tried changing channel, it maybe stayed active a bit longer than otherwise, but still failed shortly after activation.

So, I installed WICD, no joy.
I removed Network Manager, which I had failed to do.
Rebooted.
Started the wireless connection (I was on WEP because that seemed to work on my HP Vista laptop - WPA kept dropping), but WICD went through all the steps but hung on "Acquiring IP address".
Removed all security (No WEP, no WPA, nothing).

Was able to connect!

I've now changed to WPA, I haven't tried this on the netbook yet but will do so tonight. Hopefully then this thread can be marked [SOLVED].
