9971 VPN WIFI Phone Disconnect Problem

I have just installed at home a 9971 VPN phone (model CP-9971) using WIFI.

Since installed the phone is disconnecting and reconnecting periodically (irregularly 10- 20 minutes),

even during phone calls.

The phone is installed in a room where I have a macbook a wifi epson printer.

The ADSL WIFI router (from telecom Italia) is installed 4 mt away in the adjacent room separated by a glass door

I have disabled Bluetooth on the Macbook and mobiles on my dek and even tried to switch off the Epson printer that is near the 9971 phone

Thanks for your help.

Cheers Sergio
