Weird. Try forcing each base station onto its own WiFi channel. Use channels that aren't already in use by your neighbors (hint: on a Mac, option-click on the WiFi logo in the menu bar) and set the channels as far apart from each other as possible (e.g., use channel 1 on one, channel 11 on the other).
