Test 85mbit Netgear, bought 200mbit Devolo
I test the 85mbit version from Netgear, the type that are a self-contained unit and were connected between my apartment and the basement storeroom I have, to service my server. The best I got was 13mbit up or down, but it proved the connection could be made.
So I plumped for the Devolo 200mbit ones a) because they were cheaper, b) I got the desktop models which were cheaper still. The speed bumped up to 48-55mbit up or down, so pleased with that (it's only a server for mail and a personal website I toy with).
However, after overheating issues in said storeroom, I placed the units within my own apartment and get between 140-160mbit.
I'm thinking of adding a 3rd unit in the living room to service my Xbox 360 and ShowCenter media player (currently both on 54g wireless).
