You have to get industrial hardware built to last. I picked up an all-metal network appliance back in 2015 and it’s still kicking. Handles gigabit just fine as well. Here’s a random example of the type of thing I got (the exact one I got went out of sale years ago): https://www.amazon.com/dp/B07FKMJGD6/

You also end up having to split out your Wi-Fi to a dedicated access point this way for another ~$80, but you end up with a rock-solid setup that you can upgrade the software on year over year. I’ve ran at least 3 different OSs at this point since I’ve owned it and it’s handled them all perfectly. I’ve only had to upgrade my Wi-Fi AP once in that time.
