How can I log-in to my router settings?

Dig out the modem/router manual. If it is web managed, you should be able to enter a pre-determined IP address (per the manual) that wakes up the web management component in the device. If it is not web managed, then you may have been presented with a management application's dialog asking if you wanted Keynote to remember your password for you on Mojave.

You may have to reset the ActionTec, and start over with a new password and configuration settings.

I have an Actiontec GT784WN modem/router and my log-in credentials are not recognized. Is there a way to log in?

When I used OS Mojave I didn't have to log-in.

I am admin but my username and password didn't work.

This has to be the router admin and passwd— this is set up when the router is at its default settings an anybody can log into it on your Network.

Some default settings on routers use admin/admin as the default, Look for support on the developers website if in doubt—different manufactures use different default login credentials

I would like to do a factory reset but an Airport Time Capsule is my Access Point/Base Station for my wireless network which complicates things for me. Can you possibly tell me: if I reset the Actiontec and start over with a new password and configuration settings what settings will I be losing?

You will only be losing the network settings.

If your TC is doing the routing, it is only getting the Internet IP address from the Modem. It then divides up that single IP amongst all the clients. So, you shouldn't lose anything resetting the Modem.

You will again have to configure the Actiontec to "bridge" mode or whatever is similar.

Confirm that you mean the TC is distributing IP addresses to all your devices and not the Actiontec router?

If the ATC is in Bridge mode, then you are using the Actiontec as your router. You will need to completely set it back up after resetting it. Most of that setup is automatic, though.

Your router may not have any default username and password.

If it was supplied by your ISP, then the username and password should be on a sticker on the bottom/back of the router.

Have you tried that one?

If you end up needing to reset the modem, make sure you do set a username and password to manage it--and write it down.

When you reset it, the nameplate username and password should work.

If it doesn't, you'll need to contact your ISP.
