Installing driver for Edimax EW-7318USG Wireless Adapter

**Lourie2** · May 8th, 2008

Having given up hope on the Belkin adapter (F5D7050 v5000UK) which I impossibly could not get to work in Hardy (It worked in Gutsy!), I got myself an Edimax EW-7318USG Wireless Adapter. Trying to install the driver with "HOWTO: RT73 (RT71) serialmonkey drivers
Posted by alex - 2007/10/08 04:57", I have reached a point where my hardware is not detected. Any help on this? Here is where I got:

I think that you might be doing some of these steps in the wrong order. eg from the instructions I was given you need to blacklist first. Here are the instructions I use:

1. sudo rmmod rt73usb (remove old drivers)
2. sudo gedit /etc/modprobe.d/blacklist and add these lines to the end of the file:
blacklist rt73usb
blacklist rt2570
blacklist rt2x00lib
3. sudo apt-get install build-essential
4. sudo apt-get install linux-headers-`uname –r`
5. get the latest version of the driver source from the serialmonkey site. The name is rt73-cvs-daily.tar.gz. I saved it in my user dir:
6. sudo wget http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz -O ~/rt73-cvs-daily.tar.gz
7. sudo tar -zxvf rt73-cvs-daily.tar.gz
8. cd ~/rt73*/Module
9. sudo make
10. if the file produced is 2Mb in size there is a problem as it should be about 250Kb. To fix this, use the "strip" command:
strip –S rt73.ko
11. sudo make install
12. sudo modprobe rt73
13. as sudo, edit /etc/modules – add the text rt73 at the end
14. as sudo, create text file called rt73 in /etc/modprobe.d
15. put the text “alias wlan0 rt73” in this file
16. remove /etc/modprobe.conf as it’s no longer needed (back it up first – but note I didn’t have one)
17. add the following to /etc/network/interfaces file. You might need to customise this to suit your particular situation (eg if you don't use WPA encryption):

auto wlan0
iface wlan0 inet dhcp
pre-up ifconfig wlan0 up
pre-up ifconfig wlan0 down
pre-up ifconfig wlan0 up
pre-up iwconfig wlan0 essid yourSSID
pre-up iwconfig wlan0 mode managed
pre-up iwpriv wlan0 set Channel=11
pre-up iwpriv wlan0 set AuthMode=WPAPSK
pre-up iwpriv wlan0 set EncrypType=TKIP
pre-up iwpriv wlan0 set WPAPSK="yourkey"
pre-up ifconfig wlan0 up

18. reboot

I hope this helps. I've got to say that I'm having trouble myself with this in Hardy. I can follow all the above steps and get no errors, but I still can't connect to my router. I get no DHCPOFFERS and I'm not sure why, but see how far you get anyway.

Thanks for this, I'll give it a try tonight. Just need to know, do I start from Step 1, or is there something I need to do beforehand, perhaps to undo wrongs I have done sofar? I'm a newbie, so please excuse my ignorance.

Lourie2 - no problem, glad you got it working. I've got a few of these edimax cards (pci, usb, pcmcia etc) and they do seem to work ok once you get the right drivers loaded...but it would be nice if they were supported out of the box.....oh well, maybe in intrepid ibex eh???....(well I can hope!)
