It's virtually impossible to troubleshoot a wireless LAN in a forum thread.
Seriously, it's virtually impossible!
Find someone COMPETENT in Windows networking to come fix it; if you dont have a friend that knows what they are doing, email me and I will be happy to try and help.
[email protected] At this point, we have no idea whom the culprit may be... HP and Toshiba can load some NASTY Wireless LAN software onto thier notebooks, I suggest stripping it down to it's lowest common denominator and installing the Intel PRO+set software/driver package to get it on line.
The best thing to do is make sure that you have a workgroup that CAN file/print share. Once that is done, and the missing link turns out to be the notebook, then it can be troubleshot. Also, as Jorge pointed out, just because you are on the INTERNET w/your notebook, it does not mean that you are on the same subnet, you could be on your neighbors’ WAP and need to rule that out as well.
Chances are you could spend 10 hours posting, reading, etc... in this thread, and possibly not even get this resolved.
Find a competent MCSE, or CCNA, etc... And you could have your problem solved in 10 mins.
Chances are it's something simple, but overlooked.
