If there is a hard wired internet connection, a wired network switch in any location can give you extremely fast service for next to nothing. Most homes don't actually have gigabit Internet speeds, but home networks can do gigabit networking for very little money.
$16 for a 5 port switch. That gives you one 'feed' connection, and four devices which can then connect to it.
If you had a bunch of network connections you ever needed to make, you can get bigger switches as well...
I use a 24-port switch in my basement for my equipment, and may be upgrading it to a 48-port model shortly.
