my name is /dev/human and I would like to ask for some help.
I recently bought two same notebooks. I installed Debian 9 "stretch" on both. They have the same WLAN configuration, i.e. the /etc/network/interfaces and /etc/wpa_supplicant/wpa_supplicant.conf files are perfectly the same. I don't use the "network-manager", "wicd" or similar tools.
Now, one of these two notebooks has the following error: sometimes, there is no WLAN connection after suspend. Not always, but perhaps 0.5-1 times per day (average).
In the system logs, i found the following suspicious messages:

[13239.321712] PM: Device phy0 failed to resume async: error -5
WLAN and Bluetooth card: Intel Dual AC 8265 & Bluetooth (M.2 2230)
Kernel: default, i.e. "4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07)"
Version of Package "firmware-iwlwifi": "20161130-3" (stretch)
I tried the firmware-iwlwifi package from backports, too, but the problem persisted.
Anyway, the newer firmware isn't necessary. Look here for the list: https://www.intel.com/content/www/us/en ... rking.html
Intel states for my card:
Device: "Intel® Dual Band Wireless-AC 8265"
Kernels: "4.6+"
Firmware: "iwlwifi-8265-ucode-22.361476.0.tgz"
The kernel page says the same thing: https://wireless.wiki.kernel.org/en/use ... rs/iwlwifi
The firmware-iwlwifi package from the stretch repository contains that driver.
Look here: https://packages.debian.org/stretch/firmware-iwlwifi
As I said earlier: the other notebook runs perfectly fine!* Intel Wireless 8265 firmware, version 21.302800.0
(iwlwifi-8265-21.ucode)
* Intel Wireless 8265 firmware, version 22.361476.0
(iwlwifi-8265-22.ucode)
I would really appreciate your help!
