How to Reset All Wireless Connections
Network adapters enable users to access specific wireless connections. If you are having trouble getting online or maintaining a reliable wireless signal, resetting the connection may solve your problem. You can reset a wireless connection directly through your computer, regardless of the type of PC you have or how many wireless connections you have available.
Open "Control Panel" from the "Start" menu.
Search for "adapter" in the search box of the Control Panel window.
Click "View Network Connections" under the Network and Sharing Center heading. A new window will open displaying your wireless network connections.
Right-click on a connection.
Select "Disable" from the drop-menu options.
Right-click on the same connection, then select "Enable." Repeat for all the wireless connections you want to reset.
