Before: max. 30 Mbit
After: about 80-100 Mbit
The values given here do not correspond to what outputs the respective control software. There is always too high values are given. Previously, however, was not enough once the link for the full utilization of the Internet line (50 Mbit) and now it is enough even for large HD streams to TVs in the living room.
The reason for the difficulty with the TP-Link adapters is otherwise the old home power wiring. In my previous apartment (new building), the TP-Link adapter ranged from easy. They brought there to the 100 Mbit.
Conclusion:
Devolo dLAN adapters 650+ play their full strength only really in poor conditions from. There they make what does not create competition.
