Hi!
For the last couple of weeks, I’ve been having trouble accessing the Internet on some PCs. They are getting IP and DNS. Arises by itself, I have not found any dependencies for this problem, but there are a couple of patterns to fix, sometimes it helps to restart the adapter / pc, change the MAC address, issuing a static address, but after some time they kick out again. If you connect via a Wi-Fi adapter to the network of the same Mikrotik, everything works without fail. Problems at the physical level are excluded. As a quick fix - put a TP-Link (heh) between the Mikrotik and the switch, and everything works fine.
There are suspicions that it may be due to changes in configuration at the ISP. I also have some questions about it, but for now, I want to figure out what the problem is with the local network.
