I have yet to be able to roam well between APs using the 7920 phone. I right now have 2 1230 APs running c1200-k9w7-tar.122-13.JA1. I have them spaced at AP1 channel 1 AP2 channel 6. Site survey mode picks up both APs. The APs are on the same VLAN. When I walk toward AP2 I see the signal weakening from AP1 and getting stronger to AP2. However the actual kick over takes a few seconds like about 10 seconds. In the mean time due to poor signal from AP1 the call quality gets really poor. And sometimes the call is even lost before the phone switches APs. Ive tried adjusting the TX power on the 7920 to 5 and 1. With very little difference. any suggestions?
