We have received several support requests lately about Windows 7 based computers not being able to connect at all or having "limited connectivity" when used with WMWifiRouter in Cellular to Wi-Fi mode. 

Quite surprisingly, for a fair number of these support requests the issue was the Wi-Fi driver used by Windows 7. It appears that Windows 7 occasionally installs the wrong (or a severely outdated) Wi-Fi driver. These drivers often work partially and may actually be able to connect to access points, which might be a reason it is generally not noticed the wrong driver is being used.

If you are having connectivity issues with Windows 7, we advise manually updating your Wi-Fi driver. Using Windows Update will generally not get you the correct driver. If you are using a seperate Wi-Fi card or Wi-Fi USB dongle, please go the manufacturer's website and download and install the Wi-Fi drivers from there. If the Wi-Fi is integrated on your motherbord, go the website of your motherboard's manufacturer to find the correct drivers.

Another issue that seems to be specific to Windows 7 is the computer not using the Wi-Fi connection when an ethernet cable ("wired" internet) is linked up. This seems to primarily happen with computers that are registered in a domain. If you are having this problem, you may have to go to Start -> Control Panel -> Network and Sharing Center -> Change adapter settings, find the adapter the cable is plugged in to (usually named Local Area Connection X), right click on the name, and select disable. This may suddenly make routing through Wi-Fi work. When you are done using WMWifiRouter go to the same adapter again and right click -> enable it.
