Devolo dLAN 1200+ WiFi Multiroom Kit
I live in a rather long flat and have problems with the wifi in the back rooms. I have already used TpLink Powerline once, but it has a very low throughput (6 Mbps), but we have a 25 line which we also get from the wifi router. Now for my question, do you think I can get a higher throughput with this? (homeserver) And do the devices generate a unified wifi network in the whole flat or does each device have its own?
