I just spent the last several days trying to find the solution on this site to getting my wireless connection back. I could not find the solution, so I'm trying this post.
I re-installed Windows XP Home on my Dell Inspiron 700m because the system was getting way too slow to be useful. I did msconfig and turned off what i thought might be safe to turn off, but that only improved performance slightly.
Anyway, after re-installing windows, the system is spunky again, but the previously working wireless no longer seems to work. The Windows Help told me to go to Network Connections and "click the wireless network connection icon". Unfortunately, like the other folks, the icon on my system is missing.
As instructed to other folks, I went to Device Manager and I found that everything under Other Devices had a yellow question mark or exclamation point. I went to Properties on some of these devices and the message said "The drivers for this device are not installed (Code 28)". I then went to Dell Support to see if I can find the drivers for my wireless modem. I got some files but when i clicked on the Reinstall Driver button, it said it could not find the drivers.
I opened the command line and typed "ipconfig /all" but nothing came up. All it said was "Windows IP Configuration".
So now I'm lost. Not sure what to do next. Check the modems physical connection? Any assistance would be much appreciated.
