Hello,
I'm attempting to get my belkin n300 to work with the kernel driver rtl8192cu. I
was previously using the realtek drivers but this only resulted in slow speeds.
I am running kernel 3.2.7 with the following information:
Bus 001 Device 004: ID 050d:2103 Belkin Components
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 0 (Defined at Interface level)
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 64
idVendor 0x050d Belkin Components
idProduct 0x2103
bcdDevice 2.00
iManufacturer 1 Realtek
iProduct 2 Belkin Wireless Adapter
iSerial 3 00e04c000001
modinfo rtl8192cu returns this:
filename:
/lib/modules/3.2.7/kernel/drivers/net/wireless/rtlwifi/rtl8192cu/rtl8192cu.ko

I have also ran md5checksum on the firmware file, it came back fine.
When I run modprobe rtl8192cu, this is what dmesg reports:
[ 1378.073848] usbcore: registered new interface driver rtl8192cu
Nothing else. This is what lsmod returns:
Module Size Used by

rtlwifi 81918 1 rtl8192cu
mac80211 165677 3 rtl8192cu,rtl8192c_common,rtlwifi
cfg80211 141272 2 rtlwifi,mac80211
What should I try next to get this module working? I hope I have given enough
information on trying to troubleshoot this.
Thank you.

Your device is in the current tables with the insertion patch date October 2011.
Unfortunately, I failed to Cc it to Stable, thus the patch was not backported to
3.2.7.
You could either choose to get a recent version of compat-wireless, or you can
echo "050d 2103" > /sys/bus/usb/drivers/rtl8192cu/new_id
(as root). That should bring the device to life.

Is that only about device table? You can always ask Greg to cherry-pick :)
