Thanks, but I spoke too soon. Shortly after writing this post, the network yet again disconntected. The network is still visible to NetworkManager when this happens, but it will not reconnect at all until I reboot.
I do not know at this point if it is related to wpa_supplicant or not, but this long supported chipset will not work consistently. IPv6 related? I have disable it. We’ll see. In the meantime, if anyone has any idea what logs to check when this happens, I would appreciate a clue.
Thanks
Bob
