Background:
-Brand new router as of Aug. 30, 2005
-Windows XP-SP2 OS
Symptons:
-If connected directly by ethernet cable to a port on the back, the connection to the router works without issue.
-If connected via wireless, the connection drops after about 5 minutes. A simple "repair" of the wireless connection restores the connection. Very annoying.
FIX:
-Trying all channels found that some channels were more stable than others. Picked the channel the most stable.
-Upgraded firmware to "v4.20.6, May. 26, 2005"
Moral of the story: I bet the problem only shows up with service pack 2.
