I had a 2.4Ghz router in my apartment, I couldn't get it 3 rooms away at times and when I did get it, it was never better than 2 bars.
Here is another thing, i turned my comp one way I got 2 bars, then 2 hrs later -gone- no explanation, who can I complain to, then I turned my machine a little again and 1 bar. I can't see WiMax being much better than the issues that plague local WiFi, at least WiFi is free (another words either free at, say McDonalds, Starbucks, Airports, etc. & free at home cause the wireless router is included with the home's broadband service or at least, it has been for me).
