So I have managed to get a serial/uart connection up and going on a TP-Link Archer AX1500(Ax10). I understand that there will be no support for these devices but I'm not really sure where else to try for help.

The problem is that I can't login through my uart connection. All the standard login/passwd combos don't work along with common names and my web gui created password. The webpage/gui on these devices don't require a user name that I saw, just a password.

Two names I've noticed do something weird, admin/(any password) and guest. If I use the admin combo, then it kicks me out to the "Press enter to activate this console" line as opposed to showing me the "Login failed" and a retry. If I just use the username guest, then it does the same thing without prompting for a password.

Any ideas on how to get into this or a better place to get help would be greatly apricated. My goal is not so much to use this as a router but a testing/learning ground of sorts.
Thanks!

I was also Stucked at the Promt, so I dumped the Firmware of a vr600v via CFE and failed on binwalk.
But with your hint on admin I searched for admin and found this:

admin:1234:1:1;guest:guest:0:0;test:test:1:1;$

It is the /etc/vsftpd_passwd file

and i also found the WebIF passwd in /var/vsftp/etc/passwd for all the lazy scriptkiddys.

So at least, it was easyier, then get the credetials from a Fritz!Box, if someone know, how to open a Fritz!Box cable, maybe he/she/it would help me?
