Authentication problems on all my wireless devices but this android phone

[dpinman57]

I have a new AC1900 archer C9 wireless router, all my WiFi gadgets have an authentication problem connecting tried all the expected procedures nothing is working, didn't have an issue before with old router, I know it works because I'm sending this message on my android just fine. No details on what authentication issues to explore just the notification any advice would be appreciated thanks.

Explain "authentication problem".

Not being flippant here - is the wireless password being rejected?

What error message(s) do you receive?

Who manages the router? What encryption is being used?

Take a close look at the Android phone's wireless configuration. Use that information to configure a second wireless device.

Check the Archer AC1900 router's current DHCP range and settings. Ensure that the router is configured to provide the necessary number of DHCP provided IP addresses.

Failing that:

Recommend a factory reset on the Archer AC1900 per the User Guide/Manual.

Go back to the basic factory settings.

Start over and focus on getting one wireless device connected to your network via the Archer router.

Keep notes and change only one thing at a time.

Please be aware that you may lose the Android's wireless connectivity as well.
