I did some more testing to try and localize the problem.
My original analysis was incorrect.
Using my Android phone set to wifi mode, I was able to conclude it wasn't that specific laptop.
I could see that when the laptop disconnected, so did the android.
The wifi signal from the router itself seems to be dropping very frequently.
I even tried moving the laptop into the room near the wifi router and still got drops.
Right now I am trying to see if there is some interference maybe from a neighbors cordless phone.
I am testing with setting the wifi channel to a specific number instead of auto. So far, no difference. I tried 2 and 8 (not sure what the "best" channel is ) and now am trying 6.
I should let you know I am connected to the Internet with Clear Wimax.
I also separated the wifi and wimax routers so that they wouldn't interfere with each other. Yet still get drops.
