No comparison to develo 1200+ ;-(

I would have liked 650+ again changed from devolo to AVM powerline adapters. the 14-day trial broke the TCP / IP connection to a SQL Server Express from again. I have not had time to examine the problem in more detail, but in the end I had no choice but to switch 1200+ devolo adapters.

Both adapters do not currently have firmware update (currently 2.0.0) is available.
The AVM adapters no additional software is required, password, and updates can be on the Fritz! OS GUI set / install. The devolo adapters 1100+ This is only possible via software "cockpit".

The AVM adapter reported a slightly higher possible data transfer rate of 220 Mbit / s, the devolo adapter show here (FB 7490) 170 Mbit / s. However, the devolo adapter significantly more reliable in terms of the network connection.
