Question

Mikrotik

Greetings! Help a newbie solve a problem.
I inherited MikroTik hAP AC connected the Internet to it, everything works, but I also need the Internet on the second floor where MikroTik does not finish. I connect TP-LINK to Mikrotik via LAN, but TP-LINK "does not see" the Internet (((
How to solve the problem?

Answer 1

The problem was solved tritely simply: the ip of the router was determined after I checked the Unicast DHCP checkbox on the tp link (attached the screen)

Answer 2

On TP-Link - disable DHCP and set its address from the Mikrotik subnet (according to the standard, the Mikrotik subnet is 192.168.88.0/24
After that, turn on the cable in TPlink to the lan port - everything is
the same on Mikrotik - on the last screen - turn off the fasstrack rule

Answer 3

in TP-Link, specify the type of connection - Dynamic IP and connect the Internet connector to the Mikrotik.
