Thank you for the links.
An official power supply certainly couldn't hurt and at least would rule power out as a possible cause.
From one of the links you posted I see brownout can be expected when the power drops to 4.6V.
Although my power supply was not listed in the links you posted I did find a test of it here:

Mine is the A1357.
Their test indicates that under load I can expect a voltage sag to 4.4V at 2.3A.
Maybe that is my problem.
I'm not really sure how much of a strain I am putting on the system at this point. I don't really have the pi doing anything. I have configured the wifi as described and I do have apache running, but I have no web app running.
I only connect to the ap from my one laptop and then attempt to ssh which freezes intermittently. As I mentioned I am not serving a web app yet - (its difficult to write anything when the system freezes up every few commands).
Thanks for the info.
