Wireless Connection Unstable

1) How do you determine if your wireless adapter supports rf monitor
mode?

2) Are there any cards/adapters that do support RF monitor mode?

PS: I'm not talking about promiscuous mode, as I care nothing about
anything after the MAC layer; I would just like to see why my
connection is very unstable. Granted, I do have a cheap access point &
wireless USB adapter (total came to about $50), but I would like to see
if there is a reason why they get disconnected. I have done the basics
and have even gone as far as to put the access point within 2 feet of
the computer with the wireless card and low and behold the connection
gets broken (but reconnects with each other within 2-3 minutes).

Would the access point or the usb adapter probably be the most to
blame?

I'm not looking into a "just buy this" solution you'd hear from a Best
Buy salesman or whatever. You can give me the technical details. I've
tried to use Ethereal but apparently my cheap usb adapter doesn't
support rf monitor (or even promiscuous mode). There are no other
access points in my vicinity (of my apartment) so please don't think I
have malicious intent. I just have an investigative mind.

Sounds like something is interfering with your equipment. IE. cordless
phones, microwave ovens, other wireless equipment, perhaps a neighbors.
Have you changed the channel? Try channel 1 or 11
