Troubles connecting two computers

I’m looking to connect two computers, Comp A and Comp B using a NetMetal AX (no internet, just two computers talking on their own network). I wish to use static IPs. Comp A is able to connect to the wireless network provided by the NetMetal. I can ping the Netmetal from Comp A. All seems good there. Comp B is physically connected to the NetMetal AX via an Ethernet cable, but I can’t seem to get the NetMetal to see it. If I put Comp A and Comp B on my home router/network (no NetMetal AX), I am able to get both computers to ping each other. I’m very new to networking in general, so I suspect my settings are incorrect in WinBox.

I am using WinBox v7.18.2

The following are the settings I’m using:

In the “Internet” section of “Quick Set” in WinBox…
Port: Eth1
Address Acquisition: Static
IP Address: 192.168.0.111
Netmask: 255.255.255.0
Gateway: 192.168.0.1

In the “Local Network” section of “Quick Set” in WinBox…
IP Address: 192.168.0.111
Netmask: 255.255.255.0
DHCP Server is not checked
NAT is not checked
UPnP is not checked

Comp A has…
Static IP of 192.168.0.123
Netmask of 255.255.255.0

Comp B has…

Static IP of 192.168.0.248
Netmask of 255.255.255.0

Please let me know if there is additional info that is needed.

Thanks in advance!

Post your full configs. "Not checked" tells nothing.

It looks like you want to use your L23UGSR-5HaxD2HaxD-NM as a bridge, bridging ether1 and the WiFi interface. But in your current config, mode "Router" is currently selected, ether1 is outside of the bridge and acts as a WAN port. If you plug Comp B to ether1 then this computer is on the WAN (internet) side and will no have access to the devices on WiFi that is in the LAN side.

The easiest would be to reset the device back to the default configuration, in that case it will have a PTP Bridge configuration and is what you need (choose the AP mode not CPE). Afterwards you can change the default static 192.168.88.1 IP address to 192.168.0.111 if you wish. But do not switch to AP Router mode!

You are not using Winbox 7.18.2, you are probably using RouterOS v.7.18.2 through either Winbox v.3.xx or Winbox v.4.xx

Follow instructions here:

and post your configuration.

Conceptually you need to put all your interfaces (ethernet and wi-fi) into a bridge.

This bridge (and not the single interfaces inside it) might be assigned an IP, this IP is not strictly needed if you access the netmetal only through Winbox, see:

Quickset is better NOT used, but if you really want to use it, use it ONLY ONCE and after a device reset, see Rule #4 :

The problem is that when you run Quickset more than once, some of the settings of the previous run may not be updated, leading to an inconsistent configuration.

This ^^^. Don’t bother posting your configs for the moment.

Reset to default config. Make sure the 2 computers have DHCP clients enabled. Plug them into anything other than ether1. Check IP addresses are on subnet 192.168.88.0/24. Ping should just work. Once you have reached that stage, you can set static IPs.

Come back and post config if it does not work.
