881w Router and wireless 9971 phones

[Niels Kaae]

Hi.

I am using a 881 Wireless router in a DMVPN hub and spoke setup and I have a problem with the Cisco 9971 wireless phone.

The phone keeps dropping of the network. Every 30-45 minutes the phone unregisteres and register again also in the middle of a phone call.

Anyone any ideas why?

Kind regards Niels

What is the RSSI between the routers AP and the 9971?

"Excelent" is the best average reply to that. It is more than one phone in the same office that has this problem and readings in the office shows the signal strenght to be in the green.

Hmmmm ... 881W only has 2.4Ghz radio isn't it?

I have the same problem. Did you find out what was causing it? What's more, now when my phone drops it won't reassociate with the 881 until I do a factory reset and re-enter the wireless config. That may be a seperate issue. About ready to drill a hole in the wall and hard wire the phone.
