Problem is now worse and I've spent many more hours trying to fix:
Windows Wireless connections in Network Connections menu says:
'No wireless networks were found in range. Make sure the wireless switch on your computer is on...'
Notes: wireless switch is on. Tried turning other wireless programmes off, and ticking the box to 'use Windows to configure my wireless network settings'. Still not working.
So I moved on to the Intel Proset Wireless Wifi program. It is able to see the modem, but no matter how I configure it, and making sure other programmes are turned off, it won't connect.
Then I moved on to the ThinkVantage Access Connections program, but, again, although it can see the modem, no matter how I configure it, it won't connect.
Have tried the help menus and options for all three programmes and Qwest.
Am out of options.
Is it just that the computer is unable to acquire the IP address still and that is why I can't connect through either of the latter programs . . .?
