I still wasn't able to resolve the issue. I am not sure how to log everything that is happening on interface ether1. I would like to monitor EVERYTHING that is happening when I connect the cable. How do I access lower level logs on the interface? It Is still not at all clear ( to me ) if the issue I...

It Is still not at all clear ( to me ) if the issue Is just the DHCP client or something else. OP stated that port shows "no link". Which means that there's problem on layer1 (physical connectivity) or layer2 (ethernet connectivity). Until this part of problem gets resolved, layer3 (e.g. ...

Some random ideas: cables can not be ruled out with excuse of "they work with other devices" ... physical layout of connectors and sockets has some tolerances and even if they are manufactured within allowed tolerances they still could fail to work correctly (i.e. pins in device socket ma...

Point being. Use the same mac address on you asus router but change the last two and use the Quick set to change it but first do a reset with defaults on the mikrotik router. You might have to power cycle your isp modem. Not sure about the mikrotik router but I would reboot it too! This is one of t...

Hi Kaszanas I had simillar issues.. 2 Modems, one did well with the CRS310, the other did not at all (port down). PC's and other Mikrotik switches worked instantly with both modems. Drove me insane, until i gave up for a day or so. Now suddently both modem work like a charm, however, switching the ...

Assuming your ISP connection is 400Mbps or less ???

Yes it is. Why?
I do not see this as an issue when I connect through another device the connection shows up and the switch acts as intended by distributing the connection accross other ports.

Well, start by posting the exact make/model of the ISP router/modem AND a copy of your current Mikrotik configuration, follow the instructions here: https://forum.mikrotik.com/viewtopic.php?t=203686#p1051720 These are the details of the current configuration. The configuration is pretty basic. I am...

Bump. I still haven't been able to resolve the issue in any way, I have this problem for more than a month and I am unable to use the hardware.

MikroTik Community I recently acquired a MikroTik (CRS310-8G+2S+IN); I plan to leverage this hardware to self-host some simple apps with remote access. The following are diagrams of my current network and the setup I would like to be able to create. Old Network setup: OldNetworkDiagram.png Future Ne...
