Laptop wireless issues

I’ve been having problems with my wireless here – the same problem I had at TechEd.

I’ll connect to wireless just fine, and then after about 30 seconds, my system process will suddenly start using 100% of the CPU, and the whole system will hang. Turn off the wireless, and everything works fine.

Any ideas? The laptop is a Compaq Evo N600c running XP Pro.

    Same problem here… rumor is that if you use your wireless cards’ hardware config instead of windows xp’s wireless config then it just works… seems that xp’s wireless config is trying too hard to hop onto a "better wireless network" even though you’re currently connected.

    I get this problem a lot since I’m in an apartment complex with at least 5 totally different wireless access points. XP is constantly looking for another network and sometimes it detaches from MINE and attaches to my neighbors’ even though mine has WEP, stronger single etc.

    I’m hoping that XP SP2 stops this "hopping"

  2. I had some problems early this morning, but have not had any problems since… I don’t know if this may be due to the "IBM Access Connections" software installed on my thinkpad or not…

    Try restarting the wireless zero config service:

    net stop WZCSVC

    net start WZCSVC

    If that doesn’t work I’d try is disabling all of the automatic connect features – make sure "usenix" is the first (or only) SSID in the list, disable the "automatically connect to non-prefered networks" option if it’s checked, etc. Similarly, try disabling the 802.1x options since they’re not supported and could result in some odd auto-config problem.

    FWIW, since the wireless has been rock solid all day for even my Powerbook (the faraday-cage model) I strongly suspect this is a software problem.

    I had a PCMCIA card for g network access and with it in it would either connect for a few seconds or crash the computer. After trying driver updates and all sorts I found a slight hairline fracture in the card (it had been bent).
