Using Linksys here with a router and 2 unmanaged switches and a hub, couldn't be happier. Everything is gigabit and I can transfer files at 111 MB/s . As for your AV receiver I assume its network capable. If you can run a cat5e or cat 6 cable from your router down to your basement,from there you can use a switch or hub if you want to have more than just your receiver hooked to the internet.. I live in the Yukon and it gets -40 here and all I did was drill a hole in my wall and run the cable one the outside of the house. Goin on 3 yrs no problems.
