Yes these will do what you want within the limits of how these work. I won't duplicate the user manual but these need to be on the same mains circuit for them to communicate with each other.
So here's the picture I see.
Cable modem -> first Powerline Ethernet Switch -> over the mains -> second Powerline Ethernet Switch -> Router.
In this scenario we NEVER use the other 3 ethernet ports.
Hi - hope someone can help.
I have cable broadband (Virgin in the UK) and use a Netgear wireless router. I have just bought an Xbox 360 and want to hook it up to Xbox Live. Problem is that my router is in a different room to my TV (and xbox).
I know I can buy the Xbox wireless adaptor but a colleague told me about plugs that you can buy, which via ethernet cables, can transfer the connection over the mains and gives an excellent signal.
I saw these: http://www.amazon.co.uk/Netgear-XEB1004-85Mbps-Powerline-Ethernet/dp/B00167D96S/ref=sr_1_3?ie=UTF8&s=electronics&qid=1259677749&sr=8-3
Seems like a good deal but wanted to make sure they were compatible with cable broadband. If not which ones are?
Thanks in advance
