Hi,
I'm using Debian testing.
WLAN adapter is NETGEAR:
Bus 001 Device 004: ID 0846:4260 NetGear, Inc. WG111v3 54 Mbps Wireless
[realtek RTL8187B]

Before recent upgrade, adapter worked properly for a long time. It is still
working on another machine.
Here is part of the log during the process of connection:

I've tried to downgrade network-manager to 1.14.6-2+deb10u1, but almost the
same problem.
Eventually, I've tried to reinstall firmware-realtek, nothing changed.

I've tried upgrade of kernel on 5.4.3 (stable), also a downgrade on
5.2.0-3,  or on 4.19.0-5, but same problem, adapter tries to connect and
not successful.
No idea what to do next.

Hello,

I have the same issue and I found that it is possible to manually
connect to a WiFi network and that would indicate that it's indeed a
network-manager bug.

1. `sudo systemctl stop wpa_supplicant network-manager`
2. Follow this guide:
https://www.blackmoreops.com/2014/09/18/connect-to-wifi-network-from-command-line-in-linux/
I recommend saving the config file in a location like `/dev/shm` or
`/tmp` not to infer with the default config.

I upgraded network-manager to 1.22 and still wasn't able to connect.

I run `sudo apt purge network-manager-gnome network-manager-openvpn-
gnome network-manager-openvpn network-manager`, removed
`/var/lib/NetworkManager/` and `/etc/NetworkManager/` and reinstalled
`network-manager`. That also didn't help.

I enabled debug log in both network-manager and wpasupplicant. Here it
