Same issue. Still get notifications of devices connected, etc.   When I go to log in with the routers PW it times out. Let me get the exact error

Login failed. You may  be connected to a guest network, limited  by Parental Controls or  your network may be  unstable.

Hi,

 

What's the error message?

 

Once login via the Tether app, you need to input the device login password but not the password for your TP-Link account. Check this FAQ for details.

Are you connected to the main network of the AX55?

 

If yes, and you do remember the login password correctly, please try resetting the AX55 to factory defaults and reconfigure it to see if you can login to the device on the Tether App.

I'm a 20 year IT pro.  I know that I can do a master reset, the problem is that I didn't save a current backup prior.  My fault.  Never had an issue with consumer grade router FW in the past.

I tried the tplink website, tether app, telnet, static IPs, as suggested in other threads.  None of which work.  I have a year old settings backup I hope that has enough.

FYI.  That's not really a solution or helpful.  @Liverpool20
