This was driving me nuts for the last two days and I couldn't find an easy solution online so I figured it out myself and thought I would share it in case anyone else is stymied.
Step 1: Go to Control Panel
Step 2: in the search field type "Device Manager"
Step 3: Select "Network Adapters"
Step 4: Right click on your Wireless LAN adapter and select "Properties"
Step 5: Go to "Driver" tab and click "Uninstall," select "Ok" to any warnings
Step 6: After your adapter disappears from the menu, right click on "Network Adapters" and select "Scan for Hardware Changes."
Step 7: Let Windows reinstall your drivers.
Step 8: Enjoy a fixed Wifi Tray Icon (assuming this technique worked for you)
