I bought this Acer Aspire E15 with W10. After I bought a new router the Acer is the only equipment can't connect to wifi, only if I change to open security Mode in the router. I made a lot of reset of adapter, ipconfig, turn off both firewall but still I can't connect to the wifi at home.
This issue could be either due to Static Router, where the Router does not respond to the request from the computer or could be a bad driver, Restart your router as philetus suggested, & at the same time unininstall & reinstall the driver from device manager.
