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
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] Module Size Used by rtl8192cu 67723 0 rtl_usb 18448 1 rtl8192cu rtlwifi 63229 2 rtl_usb,rtl8192cu rtl8192c_common 48877 1 rtl8192cu mac80211 596969 3 rtl_usb,rtlwifi,rtl8192cu cfg80211 479757 2 mac80211,rtlwifi
dmesg | grep firmware gives:
[ 61.782478] rtl8192cu: Loading firmware rtlwifi/rtl8192cufw.bin
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!
