Any update on this ? My router (Centro Business 2.0) is in the basement and my Gigaset Maxwell C is in the office on the first floor. The phone looses the connection with the base. I had hoped the Gigaset Maxwell C as business phone would have had an ethernet connection, but the only way to make a connection with the base is over wireless DECT. I hope a DECT repeater on the ground floor will do the trick to brige the space between the basement (sous-sol) and the 1st floor, but not sure which DECT repeater one to buy for the mentioned router and IP phone. Any help or recommendation ?
