Something seems amiss with the DD-WRT software version on this thing. In the WiFi settings there's supposed to be a "Channel" field to pick a WiFi channel to use, but no Channel label or entry field exists. Maybe that's why it seems as if there's no WiFi out of it. :-/ I tried all of the various configuration options - AP/Client/Client-Bridge/etc./etc.
There's a newer version of DD-WRT that I've downloaded, but I don't have time to fight with it now. Maybe next weekend...
In the meantime, I've ordered some dual-band bare bridges (that seem to have some better reviews than the cheapie listed earlier). It's a bit more money, but I'm hoping it'll have less aggravation - http://www.amazon.co...oduct/B0062K5JAI/ . I also ordered a dual-band repeater - http://www.amazon.co...oduct/B0084ZYI88/ Here's hoping these bits are plug-and-play...
All of these things seem to be a crapshoot. Apple (and/or Google) would make a new fortune if they decided to go into home wireless networking business and made stuff that really was plug-and-play for most everyone.
I'll report back with any success.
