I am running a GSv4 as a (dsl)gateway, and a Gv2 as WDS device. I am using WPA/TKIP and not broadcasting. When my MAC G4 sleeps and wakes up it will not reconnect and when I attempt to manually reconnect, it returns an error saying the device does not support selected encryption. if I broadcst there is know problem. I do not have any problem if I use wep.
