MikroTik

Hi all together,

probably I’m having a quite weird issue, maybe it’s just paranoia.

This morning I plugged in my new hAP ac2 and connected it with my router, a Fritzbox 6490, which is the gateway to the internet.
After that, I needed to leave the house and I came back hours later.
Then I saw that AP was offering a free WiFi with no passphrase, also the web GUI is unprotected.
Being connected with the hAP via WiFi, I can reach all network devices, including Raspberry Pi’s and stuff.

Now my concern is that in the meantime Someone accessed my network and maybe installed a persistent accessibility onto the hAP to be able to access the network from outside without having to be connected with my network, e.g. via WiFi because I set a WiFi password and an admin password now, of course. I’m living in Berlin, the chance someone with technical experience found my open WiFi is high.

Is there a way to completely re-install the firmware to undo all possible settings made to the hAPs Linux?

Netinstall

What were the firewall rules like on the hapac2 that you added to the network?
In other words, no point in putting new firmware if you are just going to repeat the errors.......

See Para B for FIREWALL assistance.
See Para H for netinstall guidance

After hours of struggle (because I only have a MacBook Air without Ethernet port), I made it work.

Thanks guys!
