Does ethernet signal quality depend on the desktop adapter?

My adapter is quite old and thus cannot hook up to 5G wireless connections. Because of that, and because wired connections are faster (I believe?), I intend to run a ~20m ethernet cable through my house, connection the router and desktop directly.
Should I consider upgrading my adapter, or will it not affect the ethernet connection?

The adapter in question is a U.S. Robotics Wireless 802.11g PCI Adapter.

I would not think there would be that much difference in wired connection not on 20meg
Powerline network adapters are probably your best option. Here is Tom's 101 on powerline -- http://www.tomshardware.com/reviews/network-switch-guide,4047.html#p1

The newest standard is AV2. It will provide the most bandwidth.

a wired connection will give you the best connection for your internet. the wifi adapter is separate so it will not affect your wired connection in any way

I'd rather keep it simple and stick to an ethernet cable. I'll admit, powerline seems cool and convenient, but I don't feel confident messing around with what's happening in the internal electrical circuits of my house.

After taking a look at the ports, I don't know why I ever thought the ethernet port was in any way connected to the desktop adapter. Thanks for the reality check!
