My google wifi is connected via ethernet to a modem in my livingroom and I have one Wifi point in my hallway to deliver the wifi signal to the computers in the back of my apartment. My new job is requiring me to have a hard wire connection and I am wondering how to connect my google device via ethernet to my computer (located in the back of my apartment)
You have a few options. First, the primary Google WiFi (the one connected to your modem) has a second "LAN" Ethernet port. You can connect a computer to that, or connect an inexpensive (unmanaged) Ethernet switch to make more ports available and connect a computer to that switch.
Second, the secondary Google WiFi (in your hallway) has two Ethernet ports you can use to connect nearby wired devices via Ethernet. On a secondary, you can use either port, or you can connect a switch and make even more ports available. The only possible issue here is that while your computer will technically be connected via Ethernet, there is a wireless mesh hop between that secondary and the primary. So, if that's a problem for your company, then you need to use the first approach outlined above.
I just wanted to jump in real fast to see if you saw MichaelP's reply and to see if you still needed some help on this or if you were able to get it sorted out. If you are still needing some help, just let us know and we'll be happy to continue helping.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
