Realtek RTL8187SE Woes
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.
Regards
Joe
