I have an EA3500 as well, but I'm about to abandon it as the Wifi-Connections tend to break a couple of times during the day, just as described in the forum a couple of years ago, so I wonder why it does work for you guys here?!
I still have problems with the latest 19.07.3 build on EA3500. Like Wifi being connected but no IP connectivity. Does that ring a bell with somebody ? Any specific location I need to start troubleshooting ?
