So I've had hAP ac2 for a week or so, and everything was working perfectly fine ! I'm very much satisfied with this device.
However, today something strange happened.
Suddenly, MikroTik was unable to ping gateway.
I have a router that is connected to my ISP via coaxial cable.
On my ISP router (192.168.0.1) i have several devices connected to it via ethernet cable.
MikroTik is connected to that router also via ethernet cable on the other side of the wall.
In order to communicate with other devices that are physically connected to my ISP Router, I've set MikroTik in bridge mode even on ether1 port, assigned it address (192.168.0.3) from same LAN subnet as internal ISP routers network, but I've set in MikroTik DHCP Server an option that he is the gateway.
However, here comes the weird part.
Today, out of nowhere, from time to time MikroTik decided he cannot see my ISP router that is directly connected to via ethernet cable. I noticed that because devices started loosing internet connection. When doing troubleshooting, i could see that when pinging ISP router (192.168.0.1) from MikroTik device, packets will go through without packet loss and all of a sudden, a timeout will occur for couple of seconds, approx 10-15 packets. And then it will ping again and again drop.
I thought it might be a cable between mikrotik and ISP router, so I've connected my PC directly to it, but there was no packet loss.
From time to time i also failed to ping MikroTik device itself from other devices in my home. When that happens, i could access MT ONLY from MAC Telnet, not via IP address. So something happened to it, don't know what.
What seemed to have resolved the issue (for now), is that i have performed a factory reset of MikroTik device , and it seems to be working again.
What could cause this issue? I have backed up MikroTik config using /export prior to restoring to factory defaults , so if anyone need to see some configuration that i was using, let me know.
Thanks in advance
