RE: [smartBridges] Stealing service

Thanks, Sully!  It will save me some restless nights. ;-) I'm going to look into the pppoe more closely, but probably will not implement it for a few months. Talking about WEP keys, I have all 4 WEP keys listed in the appo and on the airBridges.  I've just tried flipping the default key on the appo from key 1 to key 2, but lost all the airBridges.  I guess the airBridges don't have a cycling method to check for the next WEP key, huh?  That would be a nice feature, I think.
