I switched to a different ISP while keeping the same configuration (except the network IP changed from 192.168.8.x to 88.x). The wireless PoE MicroTik antenna now acts as the gateway, and it also functions as the DHCP server with IP ...88.1. The first device connected is the router itself, followed by other computers, a switch, which in turn links another PC and AP. I need to reach the router to add new devices to the MAC filter, but changing ISPs hasn’t helped. Previously, I accessed the router at address 192.168.8.2, but it didn’t work at 88.2. I tried running cmd as admin (Windows 7), checking ipconfig, pinging 192.168.88.255, and using arp -a. The router’s MAC address isn’t showing up. I also ran a Colasoft MAC Scanner, but I’m not sure how to reset the router without knowing the setup from scratch. Any suggestions would be greatly appreciated.

The command line tools provide different ways to check routing details. Tracing packets with `tracert` shows the path and intermediate IPs, while `ipconfig` displays the local IP address and network configuration accurately.

The router isn't listed in IPConfig and Nmap didn't detect it either. I'm not sure which commands I used with Zenmap—it's a challenging tool for someone new to the task.

I appreciate the 'tracert' utility—it's useful! The initial hop listed appears to jump from a device labeled as the MicroTik antenna, bypassing the switch and router, which is interesting. I experimented with different configurations to see how it behaves.

We are using a MikroTik product.

You ran a scan targeting the 192.168.88.* range and then attempted a broader scan using 192.168.178.0/24. The switch appears reachable in the initial scan, but the router isn’t showing up in the second attempt. This could indicate the router is offline or not properly exposed to the network.

Uncertainty, it's located on the roof and difficult to reach. Appears as a container with openings. Similar to this one: https://mikrotik.com/product/RBLHG-5HPnD

Resolved. I removed all network connections except my PC and the router. I assigned a static IP from the old ISP range (8.x instead of 88.x) and entered the previous router IP in a browser (8.2). It functioned correctly. Afterward, I manually set the router's IP to a new range (88.2) and adjusted the default gateway to 88.1. It seems the microTik didn't respond to the DHCP server. Appreciate your help!
