Nikktech tried the AVM FRITZ!Powerline 546E WLAN Adapter
A quote from the article:
Powerline network adapters may already count quite a few years in the market (i used my first set well over 5 years ago) but the main consumer base has just now begun to learn of their existence and as expected most network equipment manufacturers have recently focused their efforts in the release of models featuring 1GbE connectivity. We've reviewed such models already and although we're quite satisfied with their performance we do feel that they leave much to be desired especially in terms of features and available settings. Devolo is amongst the very few such manufacturers that have already tried to improve on that area by releasing powerline adapters with Wi-Fi capabilities but again i can't honestly say that we were overwhelmed with what they had to offer (at least the models we have reviewed and/or used so far). AVM aims to change all that however with the highly anticipated FRITZ!Powerline 546E model.AVM FRITZ!Powerline 546E WLAN Adapter Review @ NikKTech
