Right, just want to check a few things before the Christmas list is updated 
Currently using wireless network to my gaming PC as the only place the router can go means running a wire would be extremely impractical. Therefore, I am looking to improve the connection stability as gaming on wifi is annoying!
The network itself isn't great, I live in the country side and running a speedtest I get a ping of: 45ms D/L: 2.45 U/L: 0.38. Its better than some, but obviously not perfect!
I am looking at getting: http://www.overclockers.co.uk/showproduct.php?prodid=NW-032-TP&tool=3
and
http://www.overclockers.co.uk/showproduct.php?prodid=NW-048-BF&groupid=46&catid=1597&subcat=
Now,
1) The TP-link is the 200mbps model - am I right in assuming there will be no benefit to moving to the 500mbps model with my slow speed (will not be used for file transfer across the network)? any other suggestions for powerline adapters?
2) Do powerline adapters need to be on the same circuit or will it work as long as it all goes through the same fuse box? I have read mixed reports online about this.
3) Will the bigfoot network card show performance upgrades over the on-board card?
Thanks,
