Windows 7: laptop acting strange on one network

Hi, I have 2 networks, one in my warehouse and 1 home office, it is just 2 laptops, we carry back and forth on a daily basis, at my home office I have no issues it works great.

This problem started a few weeks ago, nothing has been changed, I didn't installed any new software etc. everything is the same no new hardware.

Both networks are wireless

at my warehouse, my laptop is acting strange, when I single click it does a double click, when I try to highlight something it takes forever to highlight it to copy it and so on.
the other laptop works fine,

Laptop with problems is Sony Vaio Windows 7 home edition 64 bit

Warehouse we have AT&T DSL (that is the network where my laptop acts strange)

Home Office we have Internet with cable

Any ideas what can cause the one laptop to act up and how to prevent it?



thanks for any help

Could be a lot of things but I would first re-install the cranky driver (wifi?) it may have become damaged.


Just in case run an antivirus scan.


Let us know the results
