Windows 7 detects Wireless connection but cannot connect (3Com® OfficeConnect® Wireless 54 Mbps 11g Access Point Prod. #3CRWE454G75)

Dear Microsoft,

I appreciate any help to fix the inability of my brand new HP G42 Notebook with Windows 7 to connect to my home wireless network.

Whilst I am able to browse the net connecting by cable, for the past 4 days, and an estimated total over 20 manhours, I have tried several suggested solution ound thus far online to resolve this inconvenience but to no avail.

Windows 7 detects my wireless network (OPEN WEP Security) but simply cannot connect.

Meanwhile, my husband's Dell Latitde 630 w/ Windows XP Pro and dauther's Mac Book are running just fine. 

Thanks in advance for your assistance. 




  • Programs you are having problems with
  • Error messages
  • Recent changes you made to your computer
  • What you have already tried to fix the problem


As a first step, I will move temporarily the computer to a spot near the Wireless Router to compensate for weak, and or blocked signal that might be part of the problem in the further away working spot.

In the computer itself.

Check the Device Manager for valid Wireless card entry.

If there is No valid entry, delete any Bogus Entry, and re-install the Wireless card's Drivers.

Check the Network connections to make sure that you have a Wireless Network Connection Icon/Entry, and that the Properties of the Icon (right click on the Icon) are correctly configured with TCP/IPv4 protocol in the Network Connections Properties.

Make sure that if there is a vendor's Wireless Utility the utility is Not Running together with the Windows native Wireless utility .

Make sure that No Firewall is preventing/blocking the Wireless components to get to the Network.

If everything above is OK and it is not connecting to the Wireless router. Log from any computer that is, or can be connected to Wireless Router with a Wire, disable the Wireless Security, and try to connect with No Wireless security.

When working turn On the Wireless security, and move the computer back to its original location.
