Hi All - I recently got one of the new OWC Thunderbolt 4 docks, which is connected to my 2019 16" MBP. When I plug my ethernet into the dock, my wifi router suddenly stops working.
My home internet starts with my Verizon modem. From the modem, I have two ethernet cables coming out. One ethernet goes straight to my office (and eventually into the OWC dock), the other goes to our wifi router running in AP mode (so it gets its IP address from the modem). Before getting the dock, I could plug the ethernet into a USB-C to ethernet dongle and directly into the MBP and it worked fine with no impact on my wifi.
But when I instead plug the ethernet into the OWC dock, the wifi router suddenly has errors and everything connected via wifi is unable to access the internet.
I don’t fully understand all the nuances of networking, but I’m guessing that there’s something going on with the dock that is blocking the modem from giving an IP address to the wifi router. But it doesn’t seem to be the dock on its own. Because when the dock is powered and the ethernet is connected but the dock is not plugged into my MBP, the wifi still works correctly. It’s only when the ethernet is connected to the dock and the dock is connected to my MBP, that the wifi router becomes unable to access the internet.
Any advice or thoughts would be greatly appreciated
