Problem Changing Internet Providers

I recently inherited a couple of MikroTik routers. We are changing our internet provider and I need to update the IP information. I have plugged the new connection into port 9 on the router and connected to the router using Winbox.exe to do the configuration.

The information I have from our new provider is Ip address on our equipment 88.69.69.146/30 Gateway 88.69.69.145. This information was tested with a laptop connected directly to the new connection. It was then uplugged from the computer and plugged into port 9.

I have connected to the router and manually set the speed ether 9 to the specified rate and duplex ( I also tried auto). I then went to IP and addresses and added the above information. I added a new address and entered 88.69.69.146/30, selected Interface ether 9 and it automatically set the network to 88.69.69.144. I then added a second address of 88.69.69.145 and selected ether 9 as well. I then went to tools and selected Ping and specified ether 9. All of the pings are returned as either Timeout or Host unreachable.

Have I setup the address correctly?

I have rebooted the MikroTik and power cycled the provided equipment.

Can anyone tell me what I am doing wrong?

Hello,

If 88.69.69.145 is your GW, then you should add it at IP → Routes
Click the + sign and enter the GW like this:

Remove the GW from IP → Addresses, just leave the one 88.69.69.146/30 pointing to port eth9

Thank you. it looks like that is working.
