LAN slows down file access

I am new to the whole thing of networking but have put in place a 54g
wireless link between my Laptop & my desktop PC. In turn, the desktop has
ethernet
connection to a Netgear ADSL router.
When both PC's are switched on & connected via the network link there is no
problem with file access, however, as soon as I use the desktop PC on its
own, it takes ages (often up to a minute) to open files or to get any
response from a "right-click" on them. As soon as I disable both LAN &/or
Wireless connections in the system tray, the files open immediately. Problem
here obviously is the nuisance factor involved in having to disable the LAN
as well as not being able to access the internet without having to re-enable
the LAN.
OS = the 'wonderful' Windows XP Pro.
Any ideas as to how to overcome this nonsense please?

I have exactully the same problem. I have deleted all the network shares,
and it seems to have improved a little

But any more suggestions would be great.
