Hello all, I make a hotspot with my mikrotik and its working very well with user name and passwords. But right not trying to log-in users with mac addresses. I mean that, I know users mac addresses and register to mikrotik then I want them log in without user name and password. I edit hotspot login page, I disable username and password field and I set hotspot server profile window with logging by mac but cannot succeed. Can anybody help me step by step.
What are you using for authentication? Are you using the local user database or a RADIUS server like User Manager or FreeRADIUS?
Good question 
I think local user database
Do you have the mac address in the local database? Does it have a password?
Enable hotspot verbose logging. Maybe the log will help you see what is happening.
/system logging
add topics=hotspot,debug action=memory
Try a login and check the log.
Logs are here
That looks like that mac address is not in the database or the format is incorrect. Looks like it is also checking a RADIUS database with the same result: “User not found”.
However it displays the mac address in the log is the format. Should be
XXXXXXXXXXXX
or
XX:XX:XX:XX:XX:XX
Is there any idea what to do from beginning to end, I am newbee at mikrotik.
It is simple. I just checked it.
/ip hotspot profile
set X login-by="mac,http-chap"
/ip hotspot user
add name=XX:XX:XX:XX:XX:XX
Insure you change the correct hotspot profile. Mine has more than one.
That is the format my hotspot uses for the username. Leave the password blank.
I restarted the router to insure the hotspot was starting clean with the new login setting.
I opened my web browser and went to Google. It came right up and the mac address showed in
/ip hotspot active
