Q: Macbook Pro (purchased Dec 2010) OS 10.9.5 Internet connection problems via Belkin ethernet

Hello.

I've just moved to an old house with very thick walls and positioning my BT router close to my Macbook is a problem due to the location of the BT box and powerpoint. I can connect to the router with WIFI but it's a little clunky and slow. I'd like to use my Belkin home plugs to connect to the router by Ethernet instead.

I've plugged in the Belkin box, both green lights are on steady and I've connected the computer by ethernet cable. Network Preferences show that ethernet is connected and there is a green light on the left side of the NP pane. Trouble is, I cannot connect to the internet. I've tried switching WIFI off and that doesn't solve the problem.

WIFI advanced settings are:

Configure IPv4: Using DHCP

IPv4 Address: 192.168.1.64

Subnet Mask: 255.255.255.0

Router: 192.168.1.254

Ethernet settings

Configure IPv4: Using DHCP with manual address

IP address: 192.168.1.64

Subnet Mask: [blank]

Router: [blank]

DNS Server: 192.168.1.64

Thanks to anyone helping me.
