No matter how, without at least Cat5 there are only two alternatives: WLAN or Power Lan.
WLAN in turn depends on the signal strength at the receiving end but it is also of the WLAN equipment the terminals.
So often only Power Lan is as cost-effective connection path.
In this specific case, the bandwidth of the adapter kit is specified with up to 600 Mbit. And up to is very crucial here. The achievable bandwidth depends on the conduction. So, if in the main network (switch or router) occurs the link on the top floor, the house distribution in the basement and the basement is on a different circuit, then the signal must struggle through this entire line distance and then come in my case, with still acceptable 150 Mbit on.
If you stay only once in the same circuit are infallibly far better bandwidth reachable but then one is usually well anyway close enough to the WLAN AP or cable connection. The specified bandwidth is therefore almost always only a theoretically achievable value.
Moreover, there are different designs of the adapters. In this specific case it is a great thing to be able to use the same three RJ45 connectors, saving on multiple devices to be connected to the switch. But however you always need a wall socket and because the adapter can not provide outlet implementing also become a problem.
So there is also the Power Lan some factors that you have to weigh up front purchase.
In this specific case I have incidentally replaced a kit NetGear by this TP_Link adapter and could thus increase the bandwidth by about 10%.
So if you can draw taking into account the mentioned conditions the use of these adapters into consideration will make this purchase is not far wrong.
