New mac user here and loving the switch minus one isssue that I am seeing. Hopefully its just some setting I'm missing for being new.

I have a MBP 15" and from some reason my wireless seems slow connecting to and from my XP desktop and nas. (Runs as expected on the internet and doesn't drop connection either) Copying a 15mb file to and from the devices takes about a 5 mins or so and most of the time it times out. My other xp laptop copies files to and from using wireless without issue and much faster (kind of tells me I have a setting off somewhere). A wired connection on the same laptop copies files 2 and from as expected. Anywho the wireless router is a linksys wrt54gx2.

Any help would be appreciated.
