Hello All (sorry if this appears twice. I cancelled the first one because of errors)
After five exasperating hours with three different tech support people from Linksys and one from the cable company, here is the answer:
Gateway had installed a second wireless configuration utility on the new laptop - one from Broadcom - that was conflicting with the Windows wireless setup program. Both we enabled and set to start with the computer. Apparently what was happening after the Linksys Netset software setup the wireless and the computer was shutdown was the Broadcom program would come back on during restart and interfere with Windows' efforts to establish the wireless connection. The result apparently was creation of conflicting IP addresses or something like that. When the wireless worked, the wireless address using the Ipconfig /all cmd was 000.000.000. When it wasn't, it read
169. something - which is apparently the default windows XP one. Blah blah.Why we have different programs, conflicting programs and all this to do one simple thing seems to me to be just one more example of how this computer tech stuff is too far in its infancy. Imagine if we had these problems when we got our new car home --- "If you are having trouble making the car actually go, make sure the duplicate transmission shifting strategy corresponds to the selected engine. Please open the engine diagnostic hatch and disable the Cruxmulch overdrive modular drive lockout and reposition the crank engine piston ring slave to the lowest groove. Then close the hatch, crank the engine three times and reinstall the rubber modulation connecting band. NOTE: The stock random pressure relieve valve installed in this vehicle may not work with the selected drive train. If not, please contact your engine manufacturer for the installation ID certificate read diagnostic utility. Once you download and obtain the tray installation manifest, contact the transmission manufacturer using the numbers listed on the transmission identification placard located behind the dashboard on the left side of the firewall. Ask for instructions for disabling the alternate upload shift regime. After removing all the fuel from the gas tank, press the reset button. If this does not work, call Chile."
Well... at least I got to spend the day talking to people in Rhode Island, the Philippines, Argentina and another place I forgot to ask. The laptop starts up now all nice and wirelessly connected. We now have no interest in or energy for using it.
Thanks to Jeff and to everyone for your assistance.
