I had 3 x 85 Mbit adapters and was only moderately enthusiastic about whether the low transmission rate to approximately actual 4-8 Mbit ie 500 Kbytes / s - 1 Mbyte / s totaled, no matter what the Delovo tool (35 Mbit / 4 , 3 MB) indicated. All 3 adapter in single doses on 2 floors verteit. Unfortunately no better than wireless and not even TV / video streaming so smoothly was possible for DSL 16000 was quite thin. So one more try with the 200 Mbit devices, old equipment out new devices in the same box clean. Lo and behold, there are now 1.8 Mbyte / s (14.4 Mbps) to 2.5 Mbyte / s (20 Mbit), depending on the box actually available. While that is not state of the art, but TV / video streaming and data transfer are now iO It has therefore been worthwhile to use the fastest technology, even though these devices are quite expensive and actually no me known event, the 200 reach Mbit. So clearly, if at all Powerlan, then use the 200 Mbit class, unless you just want a maximum of 6000 for the purpose of DSL Internet, then go well the favorable 85 Mbit devices.
