Hi jamco,
Yes, You can... Linksys WAP54G has only three modes. These are, the basic access point mode and the wireless bridge mode ? point-to-point and point-to-multipoint.
The web interface does not specify whether the bridge mode is point-to-point or point-to-multipoint, as compared to the WAP11 device. Which makes sense, because you don't have to. If you enter only one MAC address, then it would be a point-to-point connection with another access point acting as a wireless bridge. If you enter more than one, then it's a point-to-multipoint wireless bridge connection ? less options, less clutter and a simpler interface.
If you're thinking of buying an access point to act as a wireless repeater or a wireless client, then WAP54G is not for you, as these modes are not present in the unit.
Hope this will help you!
