Hi wpan,
When did this issue occur ? Did this issue occur before ?Have you tried to connect to another wireless connection to have a check ?This will help us to troubleshoot whether it is caused by the specifice router.
It is recommended to run the built-in troubleshoot tool to have a diagnostic:
Control Panel\All Control Panel Items\Troubleshooting\Network and Internet\Network Adapter ,Internet Connections
If the issue persists ,reinstall the network adapter driver to have a check .We may need to download the driver from the manufacturer website.
If the issue persists ,please run the following commands to reset the TCP/IP stack to have a check:
ipconfig /flushdns (Clear the dns cache)
nbtstat -RR (release and refesh NetBIOS names)
netsh int ip reset (reset ip settings)
netsh winsock reset (Reset Winsock Catalog)
Reboot
When the wireless connection is disconnected ,please also check the Event Viewer for related information to troubleshoot this issue .
Event Viewer \Windows logs \Application ,System
Best regards
