This was bought for one single purpose – to give an old XBOX wireless access to the internet. It serves that purpose perfectly.
When I got the second XBOX to run XBMC, I ran into the issue that it had no wired access to the house LAN. I heard you could get wifi adapters but I decided to be inventive and use an “open” solution. The XBOX has a LAN port so I searched around for the cheapest wireless router I could find that supported WDS. The idea here is that the router becomes a simple relay to your main wireless router. I found this EDIMAX EW-7206APg on DABS (I used dabs4work.ie) and was chuffed to see that (a) it cost peanuts and (b) it supported WDS.
It’s a very basic device with only one LAN port (like the old FON), a single aerial and a nice small PSU. Configuring it to use WDS to connect to our Linksys WRT54GS which runs the DD-WRT firmware was a little fiddly but pretty easy. It is a secure connection. The XBOX gets is IP address via DHCP and has full internet access. It can stream video from my various PCs over wifi but it’s not great, I generally just FTP the video files over to it. Transfer speed is as expected on 54Mbs connection. The box has been utterly reliable and far less hassle than some much more expensive routers I have. The only word of warning I’ll give is that many routers do not support WDS (including our pricey Netgear Rangemax) so this configuration may not work for you.
