Try plugging in by ethernet cable to the router to compare, then plug the ethernet cable into the modem (if separate) to see if this might be an issue with the router. Go to Settings > Network & Internet > WIfi > Manage Known Networks, highlight and remove the network having problems, restart PC to see if it shows up again. Try also all older drivers from Update Driver > Browse > Let Me Pick list working backwards.
If you have the latest network driver then try on it's Driver tab also to Roll Back, or Uninstall and then restart PC to reinstall the driver. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start Menu.
Update your network adapter drivers from the PC maker's Support Downloads web page using the full model number, HP Serial Number or Dell Service Tag on sticker. Try powering off modem, router and PC and then restarting in that order with 1 minute in between each. It may be a Function (Fn) key or it may be an actual switch on the side. If not right click the network icon in System Tray at bottom right end of task bar to Troubleshoot Problems.Ĭheck that the wireless button on a laptop is toggled on. Which network icon is showing in System Tray: the Wireless waves or Ethernet TV with plug? Left click to see if any Networks show up to sign into.
