I client of mine has bought 5 CP7925. After a lot of trouble adding them to the UC500 with 2 AIR-AP521G-E-K9 connected to it they're finally up and running.
The only trouble is that after a not measrable time frame they start to stoter sound. I'll even make it spookie, 2 CP7925 registerard to the same acces point 1 has stoter sound the other doesn't, SAME SETTINGS.. I'll even make it more spookie 2 other phones registard to anther acces point, one stoters the other one doesn't when i remove the battery of the one that stoters the problem is gone after a reboot, bud not with a simple reboot of the phone. (by power button)
Does anyone have an idea?
Note that after changing form WPA to WPA2 the time frame did expand and even the range expanded..!!
