It is sometimes tricky to connect your computer to the mobile device running WMWifiRouter - especially when you have just changed your network settings. Windows XP is especially problematic in this.

It is important to note that many operating systems cache wireless network information even if you have removed them or refreshed the settings.

If your computer cannot find the wireless network, or can not connect to it, the advised procedure is:

• Run WMWifiRouter and connect so it's fully up and running
• Wait approximately a minute
• Go to Comm Manager and turn wifi off
• Wait approximately 15 seconds
  
• Go to Comm Manager and turn wifi on again
• Search for the network again (it may take a few tries)
  

The above trick works often, but not always. The followup procedure is as follows:

• Quit WMWifiRouter
• Restart mobile device
• Remove any wifi networks related to WMWifiRouter from your computer:

• Windows XP: Right click your wireless icon and choose "View Available Wireless Networks", click "Change the order of preferred networks", select the network name in the new window and click "Remove".

• Windows Vista: Right click on "Network Connections", select "Network and Sharing Center", select "Manage Wireless Networks" from the left hand side. Click on any WMWifiRouter networks and then click "Remove".

• Disable and re-enable wifi on your  computer:


• Windows XP: Right click on your wireless icon and choose "Repair".

• Windows Vista: Right click on "Network Connections" and choose "Diagnose and Repair".

• Start WMWifiRouter and "Connect"
• Searching for the network on your computer - you may have to refresh several times for the network to be found, and you may have to disconnect / reconnect or quit / restart WMWifiRouter a few times.

After you have successfully bonded the computer with WMWifiRouter once, it usually keeps working without needing the above procedure unless you reinstall the software or change network settings. With the latter, the computer will often use the old settings even though you have told it to use different settings.
