Converting Time Capsule to Ethernet Only

Using the article from MacWorld below, I’ve converted my Apple Time Capsule from a WiFi to an Ethernet device. Prior to making this change, I’ve been experiencing WiFi issues with my MacBook Pro devices and with my Linksys Velop WiFi mesh system. My 2019 MBP running macOS Catalina was frequently dropping its WiFi connection, and my Linksys Velop office node would drop its connection once or twice each day and quickly recover. This was most annoying as I spend most of each day on Teams / Zoom calls.

Prior to making the change, here’s my setup:

  • Main Linksys Velop node connected to Internet source
  • Linksys Velop node in my office connected via the Velop wifi mesh.
  • Time Capsule connected to my office Linksys Velop node via Ethernet with a 6″ patch cord; hence, two WiFi radios only inches apart. Wifi was also turned on in the Time Capsule by default, and serving 2.4 and 5.0Ghz WiFi.
  • All devices connected to the Linksys Velop WiFi – none connected to the Time Capsule.

I used the AirPort tool to turn WiFi off on the Time Capsule. I honestly did not know how or whether the Time Capsule would continue to function. Good news: no changes whatsoever – Time Machine backups continued with no changes required whatsoever. The entire history of backups on the Time Capsule continue to be available.
