I've tried getting my Belkin N Wireless adapter to work on Ubuntu many times with no luck at all. Each time I seem to arrive at a dead end.

After some thorough searching of UbuntuForums and WifiDocs I've gathered some information and narrowed the problem down to an issue with the rtl819xU driver.

Here's some info that may help:

I'd like to know if 1) Is the driver is properly installed and recognized by Ubuntu? 2) What can I do to load the drivers properly and make use of the adapter?

Thanks!

I'm struggling to install f5d8053ed (Version.6002ed) device as well. What is the output of lsusb | grep Belkin? I have a 050d:815f device id, which basically means that we both have a chip from Realtek. –  Leonid Jun 26 '11 at 14:51

If you have a 050d:815f version that uses Realtek chip rtl8192su then follow the steps below to install the drivers. I've tried it on version 10.04, but it should work on 11.04 as well.

  • Make sure you have 050d:815f.

    lsusb | grep Belkin

  • Create a directory to store the driver.

    sudo mkdir /lib/firmware/RTL8192SU

  • Download the driver. Make sure you have internet connection enabled or use other pc and copy it over to the created directory.

    sudo wget http://launchpadlibrarian.net/37387612/rtl8192sfw.bin.gz

  • Unzip the driver.

    sudo gunzip rtl8192sfw.bin.gz

  • Restart the adapter. Just plug it off and back on. The light on the adapter should start blinking after few seconds, and the list of connections will appear.

If it doesn't work try following the steps outlined in this to troubleshoot and get the exact error message page.

If you're desperate on making it work I'd suggest getting an adapter from this list.

Unfortunately an integrated Wi-Fi card on my laptop is performing by a factor of 30 better then the Belking USB adapter. My Broadband connection is 10Mbit, and the download speed is @ 0.3 Mbit, which is ridiculous. Wondering if that is a problem with Linux or with an adapter. This is my second Belking USB, and I'd never buy another...

After more testing I found that on Windows 7 the same USB adapter performs at 0.8 Mbit in Windows, which is just 15 times slower then the built-in (much older in fact) adapter in my laptop, and uses only 8% of available throughput. Claims that it is "Best for Speed & Coverage" seem to be ridiculous. And the conclusion seems to be that this USB adapter is a piece of crap.

$ lsusb | grep Belkin Bus 001 Device 003: ID 050d:805e Belkin Components F5D8053 N Wireless USB Adapter v5000 [Realtek RTL8192U] Looks like I have 050d:805e. I still have no response from the adapter. No light indicating activity, nothing. I'll take a look at that message page, but I think I'll have to cut my losses and buy an adapter (or PCI card) that I know will work with Ubuntu. –  disassembler Jun 27 '11 at 14:22
