    Brand-new Dell 600M laptop with a ProWireless 2100 card (802.11b) running XP Home-SP2. Showed a good signal from the wireless router (Netgear MR314) but couldn’t connect to the Internet or ping the router. Dell tech support finally figured out that I had used the Passphrase WEP key generator a few years back and the wireless card doesn’t support that. Manually entered a new security key and I’m happily surfing the web.
    … for about two hours. Then I’m back where I started, suggesting that this problem apparently had more than one cause. Sometimes the taskbar icon shows I’m connected to the network, sometimes it warns of connectivity problems, sometimes it flips back and forth between the two messages. But in all cases I can’t get on the Internet.
    Here’s what I’ve tried without success: (1) Adding a range of IP addresses, including the ones assigned to my laptop, to the trusted zone of my firewall (ZoneAlarm). (2) Shutting off my firewall altogether (since I noticed svchost.exe was still blocking access to what may have been my laptop. (3) Shutting off the firewalls (Windows XP and McAfee) on the laptop itself. (4) Using the repair feature on Window’s wireless connection. (5) Checking device manager. Nothing amiss. (6) Installing Windows patch for SP2 (KB884020). (7) Installing AdSubtract, a proxy-based ad blocker I have on my desktop, the theory being that since I migrated all my settings with FAST, the laptop may have been looking for the program that corresponds to the settings. (8) Telling PC-Cillin’s WiFi monitor on my desktop to add 192.168.0.4 (the IP address usually assigned to the laptop) to its trusted list. (9) Releasing and renewing IPconfig address. (10) Uninstalling Intel network adapter driver (in Device Manager) and letting it reinstall itself. (11) Resetting DNS, Winsock, and TCIP/IP. (12) Installing a second Windows fix: WinsockXPfix.exe. (13) Removing Intel PROSet (in case it conflicts with Windows’ wireless card controller). (14) Manually setting wireless card’s power management to highest setting instead of default. (15) Setting TCIP/IP address manually (to 192.168.0.4). [I was blindly following the instructions of an apparently competent Dell tech support guy in the case of #10-15.]
    What haven’t I tried?

    Shortly after sending that message, I decided to uninstall the complete suite of McAfee security programs that were loaded on the laptop (which I plan to replace with PC-Cillin). I restarted -- and, amazingly, I could once again connect to the Internet!
    .... for about an hour. And now, once again, nothing.
    What the hell is going on here?
