Whats happening?

Hi guys, I have a trouble with Mikrotik hap mini. I plugin 3 devices, all working fine, but when i add one more device - fourth! Mikrotik crushed down. It’s the fourth device that’s left without the Internet. Then I reboot the Microbe. After that, I can’t go to its settings. I reboot several times, after which the Internet starts to work only over the wires - my PC is connected through the wire. The Wi-Fi Internet does not work. After that I reboot the Mikrotick again and the Internet starts working over Wi-Fi but my PC is left without the Internet.
And only when I turn off the fourth device that the Internet starts working everywhere.
Whats problem, 3 devices - it’s maximum ???

And device status is “offered” what it meaning?

DHCP lease status offering means that it is in the middle of the process - the client has sent a discover, server (Mikrotik) has sent an offer, and the client has not requested that offer. Which may be because it has never received the offer, or lost connection before it could request the offer, or because there is another DHCP server on the same L2 segment whose offer the client has chosen instead.

So I’d say post your configuration following the hint in my automatic signature below and post also a drawing of your network topology - ISP box, some other switches/routers…

Is it wrong if I laugh with: “… than I reboot the Microbe” !?! :grinning_face_with_smiling_eyes::grinning_face_with_smiling_eyes:

Seriously now: please just post your config.

When you throw the DHCP problem in the mix, I’m tempted to suggest you do the initial test again, except plug the “fourth” device in first, and see if it triggers the problem behavior all by itself.
