I have a notebook (Lenovo) with Intel's WiFi and I have minor issues

high.
Which model Lenovo, and what is the exact wifi device? Please use lspci
to identify the device. For example, on my T520:
Actually I think I found out what was happening:
- for failed connection attempts trough SSH - the notebook sometimes
switches to suspend/sleep mode and turns off its WiFi card and it
takes time WiFi connection to become active again
I wake up my machines remotely, and then have to unlock (encrypted)
/home, so my unlock script is:
unlock-axis ()
{
until ping -c 1 -W 1 axis | grep 'bytes from'; do
printf '%s' "axis ";
done;
printf '%(%H:%M:%S)T\n' -1 && ssh -X axis -l unlock
}
This is related to my impatience rather than any system fault.
These are the entries from kernel log:

I'm not sure that these messages correlate to my attempts to log in
into the notebook through SSH. The messages appear always in kernel
log.
So is this followed by an entry along the lines of:
iwlwifi 0000:00:14.3: firmware: direct-loading firmware iwlwifi-QuZ-a0-hr-b0-63.ucode
or does it say something like:
iwlwifi 0000:00:14.3: minimum version required: iwlwifi-QuZ-a0-hr-b0-64
iwlwifi 0000:00:14.3: maximum version supported: iwlwifi-QuZ-a0-hr-b0-72
The former would explain why your wifi is working, and
the latter would make it surprising that it still worked.
