Just installed a UC520 with wireless for data and handsets.
Problem is, although the signal is fine (i.e. 70% - 80% signal). It keeps intermittently disappearing from both the data and voice sides.
The laptops lose connection then come back again within a few seconds. However the 7921 handsets lose the signal and don't get it back again! We have to turn the handset off and on again and it will find signal and work again.
We've never had problems with wireless before - UC520 replaced a linksys AP that never experienced any problems.
Any ideas would be greatly appreciated.
By the way this is a small office location, single building with no obvious Interference i.e. machinery, microwaves, wireless phones etc.
