I was just sent a 4g LTE cellspot from T-Mobile to help with the low cell signal that I have in my home. It seems pretty easy to set up, however, when I went to my modem (which I have via Spectrum), I saw that there was only one ethernet port and this was taken up with my router. Now, on my router there are a number of ethernet ports that are designated as "LAN" ports, but there is only one yellow "WAN" port. Can I plug the Cellspot into one of the LAN ethernet ports on my router, or do I need to buy an ethernet switch or something so that I can more or less multiply the number of WAN ports on my modem?
I am completely new to this so any advice will be most appreciated. Thanks!
