I recently connected my bedrooms (2) to my network using tplink 1gig/500Mbps powerline plugs. I have Marantz cr603 units connected ti them via a tplink switch. Works well allowing me to stream fkacs from the router's media server. However, I have had to remove all the surge protected plugs and boards from the circuit as it would seem that they more than half the speed of the link. I'm worried now that my equipment is vulnerable. Especially as we just had a lightening storm that took out our bt verve dect phone base station. Can anyone advise a way around this? To be protected without sacrificing speed.
