Well...XP Media Center is supposed to be very close to XP Pro. That being the case, I see nothing to be gained by either going to XP Home or the actual XP Pro O/S...unless you have a clue that there is something about the O/S itself which is the problem. That's not likely
If Internet connectivity were the only issue a user had with a system, life would be acceptable
Since you are using wireless, the obvious possibility is that the system may not be properly configured...or may merely be experiencing typical spatial/connect difficulties that some users have.
As a rule, Internet Explorer messages occur for any number of reasons, many of which are valid and have nothing to do with the user. The website can be experiencing problems, the user may not have the system configured correctly, the cache may be overfilled, and so on.
The logical place to start: Event Viewer. Take a look there and see what, if any, errors are noted (probably under Applications, but maybe under System). Let us know by posting (at a minimum) the Source/module and the event ID number.
If your problems are strictly from your wireless connection, the easy way to test that is to use wire for a given period of time. If the wire doesn't exhibit the same problems as your wifi attempts, then my guess would be a configuration problem. If it does, then maybe we need to look at the hardware/drivers.
We can be better guided by any errors reflected in EV.
