Package: wpasupplicant
Version: 2:2.10-12
Severity: important

There is no problem using a closed Wi-Fi network that requires a
password. But unencrypted open networks are all wholly unusable. Many
have been tried (libraries, cafes, etc). This problem goes back to
Bullseye, maybe further back, and persists in Bookworm.
Pre-Bullseye, I think I used the Gnome and the graphical network
manager. Then I switched to Wayland in Bullseye which neglected to
present a GUI Network Manager out of the box. In preference with CLI
and text anyway, I went whole-hog CLI instead of sorting out NM.
It’s crippling to be limited to encrypted networks. This procedure was
used to attempt to connect to a public library:
===8<----------------------------------------
$ wpa_cli
> scan
> scan_results
> add_network
> set_network 0 ssid "library_free_assange"
> set_network 0 key_mgmt NONE
> list_networks
> enable_network 4
> disable_network 0
> save config
===8<----------------------------------------
Edited /etc/wpa_supplicant/wpa_supplicant.conf
Added an “id_str” field and custom identifier to the wpa_cli-generated stanza,
yielding:
===8<----------------------------------------
…
network={
ssid="library_free_assange"
key_mgmt=NONE
mesh_fwding=1
id_str="public_library"
}
…
===8<----------------------------------------
Side note: I do not recall “mesh_fwding=1” being there in Bullseye. No
idea what introduced that but I do not think it was me¹. The interfaces
config needs to be told to use DHCP for public_library (hence the need
for id_str):
$ echo "iface public_library inet dhcp" >> /etc/network/interfaces

===8<----------------------------------------
↑ It’s bizarre that there seems to be an IPv6 assignment for wls3
sometimes (IIUC), but not IPv4. I overwrote the hex for privacy but
retained format. I would somewhat expect IPv6 to work these days, but
to be clear, the network is dead. No DNS resolution. The library has a
captive portal but pointing a browser to http://neverssl.com gives a
no network message. Nor does it work to attempt to point the browser
to the library’s gateway or captive portal URL. We can see it’s
dysfunctional at a very low level because “route” shows nothing for
wi-fi:
===8<----------------------------------------
$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.16.0.0 0.0.0.0 255.255.255.0 U 0 0 0 vnet0
===8<----------------------------------------
↑ vnet0 is just noise. It’s a Tor “middlebox”. What’s important here
is the lack of wls3 rows.
