I have a 4G router (Huawei e5172) with one LAN port (DHCP enabled). I need to connect 3 PCs and 1 wireless access point to this router via Ethernet so I got a 5-port Ethernet switch and connected it to the 4G router, and the 4 devices with Ethernet cables.
The connection works when I plug the 4G router directly to one of the PCs, but the problem is that I'm not getting any connectivity on any of the devices. I keep getting the following message "Can't resolve controller DNS" on the access point.
I'm not too savvy with networks, is there anything wrong I'm doing? How can I achieve connecting these devices to the 4G router via Ethernet cables?
Your help is much appreciated!
