!! Fantastic as a alternative to the Xbox 360 wireless adapter !!
After installing the dd-wrt firmware login to your router
If you haven’t installed the firmware go here first
Navigate to Setup – Basic Setup page
Under the Network setup area , set a IP address on your range. I have chosen a IP address of 192.168.1.5, subnet of 255.255.255, and
my default gateway is 192.168.1.2 which is the IP address of my wireless internet router.
** EDIT 24/6/2010 You may need to set the “Local DNS” value if you have issues… set it to same IP as your gateway address. You can also check the DNS value from your ISP by logging into your router and checking the status page If you get really stuck try Googles 8.8.8.8 Thanks Jess for this
