R6300v2 Can't Logon - Serial number not recognized

When I put the serial number on the label off the back of my R6300v2, the one just above the MAC address, into the when Router Password Recovery screen, it states "The information you entered does not match what is saved on the router. Please enter it again."

 

Does some know how to fix this?

 

Router model: R6300v2

Serial Number: 4SL60BB0A0830

On a private network, not externally accessible.

    OK, so mwilliams' personal folder is assigned to user 33397, which does not exist, and group 32897, which probably doesn't either.

     

    drwx------ 1 33397 32897 0 Jan 30 2020 mwilliams

     

    His proper user GUID is 33988 and his group is 33281:

     

    uid=33988(mwilliams) gid=33281(domain users)

     

    So I think chown -R mwilliams:33281 mwilliams from the .home share should fix the problem.

    If not, then chown -R 33988:33281 mwilliams.

     

    If the first one works, then this script should do it for all:

     

    cd /home
    for dir in */; do chown -R "${dir%?}:33281" "$dir"; done
    chown -R admin:admin admin

     

    I'm using the GID for the group because I'm not entirely sure how to handle the group name "domain users" with a space in it.

    If you have to use the UID instead of the name to make it work, then it'll take a lot more to get that info, and it's probably easier to just do it manually unless hou have a huge number of affected users.

    You'll need to factory reset the router and setup from scratch by pressing the reset button for 10 seconds then release. Wait for the router to come to ready, then log in to 192.168.1.1 using a web browser and walk thru the setup wizard. This time write down all important information for safe keeping later on.
