I recently upgraded my Advent notebook from Debian 9 to 10 at which point the
wifi card, an RTL8187SE using the rtl818x_pci driver, stopped working properly
and no longer connects to the router A wired connection still works. Two
other laptops, an HP and an ancient IBM T42, have no problems continuing to
connect wirelessly after the upgrade.
For debugging purposes I switched the connection to a second ("Guest") wifi
network on a different MAC address (same router) and temporarily disabled
encryption. The connection still failed. Dmesg shows the following:
Note: c4:04:15:df:a2:41 is the correct router and the reference to RTL8201CP is
the currently unconnected ethernet port.

Repeated attempts to connect give the same output barring the IPv6 references.
As I know next to nothing about this wifi driver and the documentation is
unheplful, can anybody help by translating the dmesg output into useful advice
for resolving this? I'm particularly confused by the wlp2s0: deauthenticating
from c4:04:15:df:a2:41 by local choice (Reason: 3=DEAUTH_LEAVING) line.

Joe
