Network Connection from Laptop to PC Dead Slow

Timewarner Cable in NC all ready sucks. Let me just get that out of the way.

My connection to the net from my PC (wired to router) is, okay (I miss DSL). My laptop wirelessly (a word?) is okay. My laptop into my PC via Remote Desktop is dead slow.

Any tweaks anyone know of to get a good conenction from laptop to PC? Signal strength is excellent.

Both XP SP2.
Linksys N wireless router.
Laptop uses N card.
