Hi,

I have two Debian laptops at home: a Dell E7440 running testing/sid and 
a Lenovo T400 running stable with LibreBoot, both with Gnome and 
NetworkManager.

I think I always had the same issue with the Dell (I had it in 2017 I 
think), while Wi-Fi reconnects immediately with the T400. So in my case 
I suppose it is a hardware issue, either BIOS/UEFI (because I have many 
ACPI errors when booting and resuming on the Dell, and because globally 
this BIOS seems to have not so good quality), either with the Wi-Fi card.

Regards,
Yvan
