Okay, I have a Netgear cable modem, CMD31T, with a single Ethernet port. I bought a Google WiFi, so I could get WiFi for my phone and tablet. I couldn't hook up the Google WiFi because there's only one port. I bought an Ethernet switch, Brash Networks 5 port gigabit ethernet switch, model BN105. I connected a Belkin CAT5e networking cable from the modem to the switch, the desktop Ethernet cable to the switch, Google WiFi cable to the switch. WiFi works great. I can't get my desktop Inspiron computer to connect to the internet. What's wrong? Thanks.
