Router is an old Intento FG101R2 connected via fiber and has 4 Lan ports.
After fiddling around and numerous factory resets I no longer have access to router and internet via any of the Eth ports on the router, but I can access and have internet connection over wireless.
Tried with multiple machines, cables, ports, by manually adding and automatically obtaining IP settings on client machine. I also tried to configure second IP Address and Subnet Mask for LAN interface via Router's web interface but still didn't get IP settings from DHCP and manually setting IP and gateway on client machine had no success.
Following outputs are taken right after factory reset, while still having access to router and internet connection over Wireless.
Current routes are as follow (ISP's gateway X-d out):
> route show

System log after factory reset and reboot: https://pastebin.com/TZJUN5Ji (X-d out my IP, ISP's gateway and DNS server. Weird thing is that all my Mac's are 0-d out and also not sure why the ip 128.9.0.107 is there because it's not related to my ISP or me at all)
Let me know if there is anything else I can add and any help or suggestion would be highly appreciated!

EDIT:
Tried adding eth0.5 to bridge br0, got an error can't add eth0.5 to bridge br0: Cannot assign requested address .
Brought the interface down and assigned random MAC address to eth0.5 and after that I was able to add eth0.5 to br0.
Got an IP automatically via one of the ETH ports! Was able to connect to router via Web interface but at the same time can't connect SSH/Telnet via neither, Wireless or Ethernet.
Found that DNS servers got put to 192.168.1.1 so I changed those to Google public ones via Web interface. After a bit of waiting I have internet access via both Wireless and Ethernet.
EDIT: Looked around the web interface and double checked Access-control rules and checkboxes seem correct but still no SSH/Telnet access.
Tried adding other Lan ports to that bridge but that seems to break things and after that I couldn't ping ISP's gateway, so I did a factory reset and sticked to adding just eth0.5 to br0.
EDIT: figuring this out step by step, I found that other ETH Lan ports(eth0.2, eth0.3, eth0.4) weren't marked as up so I did the same thing, assigned random Mac, added to bridge and marked them up. What made it break before was that I added eth0.6 to bridge which is used for WAN on eth0.6.2. Now all the LAN ports work, have access to internet and router via both Wireless and ETH. Also now have access to SSH/Telnet over ETH, which didn't seem to work right after adding to bridge.

The issue is that after rebooting the router those changes seem to revert, ETH interfaces are removed from the bridge and everything is back to where I started.
If anyone has an idea how I could make so that those changes don't revert back I will be very thankful.
