I’m using a Pi 3 B+ with a HifiBerry Digi+ Pro HAT in addition to two Pi 3 B+ displays. The displays use WiFi and are on version 217 and are working fine.
The Pi with the HAT is using a wired connection and is still on version 173. I have it set to use the stable channel and never reboot since I have its HDMI output connected to my AV Receiver and when it reboots the receiver will often switch to it. I know the HDMI output doesn’t do much for me but I like having it and will often use it to watch the Pi reboot.
It’s been some time since the Pi was rebooted and the screen is showing three i2S errors. I don’t know when they occurred or if they are serious but I thought I would mention them. Feedback is fd8e4eff8bd07001 in case you are interested.
My concern about upgrading to the current version has to do with my use of a wired network connection and the changes I’ve read about related to how Ropieee now limits the Pi 3 B+'s wired network connection to 100 Mb. The Pi is wired to an Orbi Satellite which has Gb Ethernet ports and I assume they will auto negotiate but I don’t know for sure.
If I upgrade and the Pi can’t make a wired connection what options would I have?
I was thinking I could re-flash but then I remembered that a new install starts out using the wired connection until you access the web interface and switch to wireless. All the available wired ports I have at the moment are on Orbi devices so if it fails on one I’m assuming it will fail on all.
