[Pkg-utopia-maintainers] Bug#1038120: network-manager: WiFi connection by 5 GHz unavailable and fails

[Green]

Package: network-manager
Version: 1.42.4-1
Severity: important
Tags: ipv6 lfs
X-Debbugs-Cc: usergreen at users.sourceforge.net

Dear Maintainer,

Network Manager can connent by 2.4 GHz, but can NOT connect by 5 GHz.
Access point by 5 GHz does not indicated on its graphical inerface at all.

Wireless interface:

product: AR9287 Wireless Network Adapter (PCI-Express) [168C:2E]
vendor: Qualcomm Atheros [168C]
driver: ath9k
driverversion: 6.1.0-9-amd64

I assume that the Network Manager compiled by Debian has a bug, because on the contrary, a network-manager-gnome_1.20.0-4mx21_amd64.deb shipped with MX Linux works properly.

Best regards
