    Wireless disconnections screws up my laptop.

    I recently got a new T61. Whenever I try to connect to my University's wireless network, it disconnects a couple minutes later. Afterwards, I am unable to connect back to the internet until I restart. When I check the task manager, the cpu is constantly using ~50% resources and generating lots of heat. The computer becomes very laggy. It doesn't say what program is using the resources. I couldn't restart or shut down the laptop because it always freezes on the shutting down screen (while still generating lots of heat and creating this burnt rubber smell). Scared of overheating the laptop, I resort to holding down the power button to shut down the laptop improperly.

    How can I fix this?

    first i'd recommend running virus and antispyware programs.
    second, is this only when connecting to your university's wireless network? what if you connect to a different network?

    Check the wireless card manufacturer's website for a newer driver for the wireless card.

    You might as well try to completely turn off Windows Automatic Updates (Control Panel > Automatic Updates > Turn Off). This is what's probably causing the 50% CPU usage - you haven't said what process eats up the CPU time, but in case it's svchost.exe, then it's Automatic Updates causing this.

    Just noticed wireless adapter is set to maximum power savings. Think setting it to maximum performance will significantly decrease disconnections?

    I don't have university access right now so I'll check tomorrow.

    When you can't connect to the internet, does your wireless still show a good connection, or is there no connection at all?

    Probably not your issue, but, if you have any extra firewall software installed, you might try temporarily disabling it to see if that helps. I'm having issues that usually occurs after I put the laptop to sleep and wake back up later, but sometimes this problem occurs even from a fresh boot.

    It gets to the point where the "CA Personal Firewall" isn't happy for some reason, even though I'm showing a good wireless connection speed with the router. When it happens, I either have to disable the firewall, or reboot the pc. With Vista, I don't really enjoy waiting for another boot. Someday I hope to figure this problem out.
