The network manager keeps prompting me for a password, while i'm sure it's correct. Sometimes it connects for a minute. When i used windows 8 at the same place with the same router, i didn't have this connection problems. Apparently someone has filed a bug already (http://bugs.launchpad.net/ubuntu/+bug/1244408?comments=all).

As stated in the title the model my Belkin wifi adapter is F7D1102 N150/Surf Micro with RTL8188CUS chipset (more information about device) http://wikidevi.com/wiki/Belkin_F7D1102. I'm using a recently updated Kubuntu 13.10 installation.

When i type lsusb and lsmod in the terminal, i got the following output:

Bus 006 Device 002: ID 050d:1102 Belkin Components F7D1102 N150/Surf Micro Wireless    Adapter v1000 [Realtek RTL8188CUS]

I tried several solutions to my connection problems:

Compilation of driver provided by Realtek:

I searched for the RTL8188CUS driver on Realtek's website and tried to compile it myself using the install script. When executing the script, sudo make driverfills my screen with a repeating error: implicit declaration of function?

Installation of Windows drivers on CD with nsdiswrapper

Blacklisted original driver. Windows driver doesn't work.

(Solution) Patched version of original driver (Ubuntu 13.10)

Meanwhile I found at that someone has patched the original rtl8192cu driver link and it works!
