WiFi Won't work, Ethernet works

[Krusetv]

Windows 10. This has gradually worse, used to get yellow triangle and could run troubleshoot to repair " reset network adapter". Sometimes did a reboot that worked. Not now. Tried on different routers- same thing. " WiFi secured, no internet". Would a new usb WiFi adapter work? Routers all work with other devices. There is no wifi switch. Lenovo 580. Device mgr says network adapter is up to date.

So it's the internal Wi-Fi NIC that's not working? I'd be trying a USB one first to check. Tried a driver download/reinstall from Lenovo's website? If a reboot is fixing it it might be failing - have seen similar issues with wired NIC's that start to fail.
