I've got a new AIRAVE working behind our router (to make sure everything works). But we went all wireless a while ago, and the router and cable modem are in a windowless basement. Putting in an ethernet cable to where the AIRAVE has to go would be a real problem. Does anyone have a setup where the AIRAVE is connected to the router/cable modem via the wifi system? Normal wifi access points seem to offer the reverse solution.
You should be able to use a wireless extender (that has ethernet ports), such as: http://www.amazon.com/NETGEAR-Universal-Range-Extender-WN2000RPT/dp/B003VWZE7Shttp://www.amazon.com/NETGEAR-Universal-Range-Extender-WN2000RPT/dp/B003VWZE7S
Which basically connects to your wifi as a client and acts as a bridge between your router and whatever devices you connect to it (by ethernet or wireless), so you could put the extender wherever you want and connect the Airave to it.
Alternately, if you have the techical ability/willingness and have an old router laying around that's DD-WRT compatible, you could install DD-WRT and configure it to do the exact same thing.
The buzzword is 'wifi bridge' -- you use the wifi bridge to connect your wireless network to your AiRave. Plug the AiRave into the bridge, then configure your bridge to connect to your basement wifi network.
