BLUF: My laptop will not detect the printer on the network.
My laptop is running Windows 10, my router is the Xfinity Xfi router (Model: CGM4140COM), and my printer is a Brother MFC-J6510DW. Both are on the same network (2.4 GHz because of old printer), same subnet (10.0.0.1/24), subnet mask is set correctly (255.255.255.0). Xfinity gateway confirms that both devices are connected to the network, and that the IPs are within the same subnet. Network discovery is on with automatic setup checked and file/printer sharing turned on. Password protected sharing is turned off. Network is set to Private/home. In the Windows Defender Firewall, all File and Printer Sharing Private rules are set to allow and enabled for inbound and outbound.
I have tried setting up the printer both through the Windows Printer installer and the Brother Printing Device Installer. In all cases, the printer is not visible to my laptop. I am currently unable to ping any local IPs as well. Lo address is still able to be pinged.
At this point, I am waiting for a printer USB cable to arrive to attempt installation that way. What else could be the problem though?
