Title: Cannot use WiFi
Post by: Ev @ Mammoth on January 29, 2011, 02:50:45 AM

At home I use a direct wired Ethernet connection and elsewhere WiFi to a local hub. The computer must have a receiver-transmitter modem that connects it to hubs which doesn’t seem to be woorking.  In the past I clicked ‘Wireless Network Connection’ and got the list of local hubs.  Now clicking ‘Wireless Network Connection’ I get a box titled Wireless Network Connection displaying, “Enabling…” and then quickly displays, “Connection failed!” and then disappears.
I used to have a controller on my start list that let me enable/disable WiFi but it was accidentally deleted.
I tried System Restore, but for all dates it only stated “Your Computer cannot be restored to the [date given] System Checkpoint” –or –if not a System Checkpoint, then no explanation.
On clicking Dec 20 in System Restore these notes appeared:
   8:36 pm Removed Digital Line Detect
   8:34 pm Removed Get High Speed Internet
   4:42 am Remove EducateU
   4:39 am Configured Broadband Management Programs 2
It’s possible that on Dec 20 I ran a copy of Regwork and picked up some kind if virus – but that’s just a guess.

If you're on Windows XP, go to Start > Connect To > Show All Connections.

See if your wireless adapter is disabled. If it is, try right clicking it and enabling it. (Although it seems that it's disabled and has a problem enabling)

Thanks for the 'Right Click' suggestion to try to enable, but unfortunately it doesn't work.  Got the same boxes as described above.  Could the modem be damaged?

ridwhan, thanks for the suggestion, but I don't understand what I should un-install and then install after restart. Also, I don't know where to look for the WiFi driver. Ev

Thanks for the idea and reference, but I still have XP - considering an update.
