Subject: Problems with Realtek USB rtl8192cu
Date: Mon, 27 Feb 2012 16:09:24 +0000 (UTC)	[thread overview]
Message-ID: <loom.20120227T170610-925@post.gmane.org> (raw)

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:

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
rtl8192cu              86266  0

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.
