I recently replaced my Edge 530 with an 840. The 530 connected to my wifi network and always reconnected automatically when I got home from a ride. The 840 sees my wifi network and I can add it to My Networks, but when I try to connect, it tests the connection and says "Something went wrong. Try again." After a reboot the network has disappeared from My Networks on the Edge 840 and in Garmin Connect.
What do I have to change to get the 840 to connect like the 530 did?
