Router Model: TP-LINK, TD-W9970
Printer: Samsung M2070.
I have already tested out why the router keeps rebooting and I found out that connecting the printer via the Ethernet cable is causing this issue. I don't know if there is a specific setting in the router that should be applied, or if the router cannot handle the printer for some reason. I am really confused and I don't know what to do. Actually, the problem happens even when the printer is not connected, but it's more frequent when it is. I tried unplugging the switch and then the problem didn't happen anymore. Now I am trying to plug the switch into the router's other Ethernet port to see if the problem is maybe from the router port itself which is causing an electric failure or something like that.

Now I am still working to track down the problem but I am looking also for your suggestions and what can cause this.
