X-post: Public library wifi oddity, Linux vs Android
A few days ago I posted this to my local LUG mailing list:

XXXX "community" libraries offer free wifi, courtesy (?) of
*cough* O2. Tech support is non-existent. If it works it works, if it
doesn't, tough.
The last few weeks I noticed wifi performance degrading. Today, I
couldn't even connect the wifi network.
"nmcli device wifi list" was giving me the SSID "BCC_Free_WiFi" at 72db,
which should be enough.
Then I tried to connect with my Android phone and everything was ok. I
connected the laptop to the phone via USB tethering and the connection
was great.
Is there a chance that my wifi card is dead?
This is the output of:

Any clue?
This is a Debian Bullseye installation with kernel from backports.
$ uname -a
Linux t440 6.0.0-0.deb11.6-amd64 #1 SMP PREEMPT_DYNAMIC Debian
6.0.12-1~bpo11+1 (2022-12-19) x86_64 GNU/Linux
Somebody suggested that the Wifi provider might have a rule in place
whereas if they see "Linux", they would rate-limit or throttle the
connection.
Authentication is via browser, which is already configured to spoof user
agent to Windows.
Question 1: is rate limiting via OS sniffing a thing?
Question 2: is there a way around it?
Tech support is non-existent and in any case they wouldn't be able to
handle the question.
Thanks.
