My system seems to be working fine in that all of the devices on my home network seem to be able to access the internet. That said, I am unable to access my home router from my laptop, both devices are connected to the T-Mobile gateway via ethernet cables. I can ping the router from my laptop, however, when I try to access the router via a web browser by entering the IP Address, I can’t make a connection. Additionally, I am unable to see any of my home networked devices from my laptop. My home router is using 192.168.12.104 ad its IP Address. My laptop’s IP Address is: 192.168.12.236 and the DNS Server is 192.168.12.1.
I suspect that the issue has something to do with how the home router is configured and that the new T-Mobile gateway is somehow configured differently than the previous cable modem. My entire house is hardwired with ethernet cables and connected to centralized routers and switches. The primary router connects all of the wired (ethernet) and wireless (WIFI) devices together on a household network and the old cable modem was located next to the router and connected via ethernet.
Since the T-Mobile gateway requires line of sight locating, I have the device located in my home office next to a window and am using the ethernet connection in that room to connect the gateway with the router. However, since that connection uses the ethernet connection that I was previously using for my laptop, I have now connected my laptop directly to the T-Mobile gateway, using the 2nd ethernet port.
My question is how do I connect my laptop to my router so that I have visability to the home network and all of the devices on the home network (particularly, the network printer)? Everything worked great together when connected to the old cable modem. I’m sure that this issue can all be corrected somehow, but I need some assistance for what settings to change.
