Are you using the latest version of firmware on the wap200? If not, upgrade that and see if that helps. Is there any wireless noise in your network (other ap's in range, 2.4 ghz phones,) that could be messing with your wireless connectivity. Wireless connections work on half duplex and can only listen to one thing at a time. If your getting interference on that channel, it could be that your connected but there is too much noise on the channel. You can perform a wireless scan to see what channels are being used and manually select a channel that is not being compromised.
