HAP AC2 reset problem

Hi,

I have HAP AC2, reset it via reset button (turned off, while turned off press and hold reset button), power up, usr led blinks several time, reset button release.

connected LAN 1st port to LAN of computer, and as I understand it should give DHCP address to laptop, but it don’t do it, Mikrotik LAN port is blinking.

please guide me, what i`m doing wrong.
Thanks

BR,

connected LAN 2-5 port to LAN of computer,
1st port to WAN, default config.

yes i`m connected to first LAN port, I have in mind that WAN port will not work

Connect computer to second LAN port (or third, fourth and fifth).

Can you please explain what the problem is?

Did you decide to reset because the router stopped booting normally? That is, after turning on the power, did the router blink its lights and reboot itself?

This only works when the laptop is connected to ports 2-5.(LAN) Port 1 is configured to connect to ISP equipment.(WAN) This is the default configuration.
So what’s not working for you?
