wpa_supplicant works directly but not as wifi backend for NetworkManager

Open jsermer opened this issue 4 years ago • 9 comments

First of all, thanks for making this arch package. I'm not sure if I'm doing something wrong or it's some odd interaction between the adapter (https://www.amazon.com/gp/product/B07FCN6WGX/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) and NetworkManager itself.

Using Gnome's control center to setup/configure/connect to the wireless network never connects, but using dhcpcd and the wpa_supplicant hook from the command line works (the below command will trigger dhcpcd to start wpa_supplicant and then request an IP address (can be found in arch's wiki).

rfkill unblock 1
sudo dhcpcd wlp5s0u2

My setup is as follows:

It just continues prompting for the PSK over and over and never connects. Is there something obvious I'm missing?

Hi, set echo 6 > /proc/net/rtl88x2bu/log_level and see dmesg. Is there any new beacon occur!! in the log?

RinCat avatar Dec 02 '20 23:12 RinCat

Attached the log, but the only 'beacon' messages I see are:

[  +0.000005] RTW: OnBeacon: beacon keys ready
[  +0.000007] RTW: OnBeacon: beacon keys ready
[  +0.000006] RTW: OnBeacon: beacon keys ready

RTW: assoc reject, status code: 40 Invalid information element (doesn't follow 802.11 standard) https://support.google.com/chrome/a/answer/7172038

I guess some of your configuration does not compatible with your wifi.

RinCat avatar Dec 03 '20 00:12 RinCat

Hmm, my NetworkManager config is bare bones (/etc/NetworkManager/NetworkManager.conf is effectively blank), it's using the default wpa_supplicant backend (not iwd) and my wifi config file is:

[connection]
id=myssid
uuid=39a38116-0be8-48a7-9ffc-8a378c9330c5
type=wifi
interface-name=wlp5s0u2
permissions=

[wifi]
bssid=myssid_bssid_mac_address
mac-address-blacklist=
mode=infrastructure
ssid=myssid

[wifi-security]
key-mgmt=wpa-psk
psk=mypsk

[ipv4]
dns-search=

[ipv6]

Try change your wifi router configuration and see if it works.

RinCat avatar Dec 03 '20 01:12 RinCat

It works using the same basic config options (ssid, bssid, and psk) manually with wpa_supplicant directly but not using those same options with NetworkManager (I'm actually sending this message over the wifi adapter manually configured using wpa_supplicant command line):

wpa_supplicant -B -c/etc/wpa_supplicant/wpa_supplicant-wlp5s0u2.conf -iwlp5s0u2

Which leads me to believe it's some sort of NetworkManager bug/issue/misconfig/etc

jsermer avatar Dec 03 '20 01:12 jsermer

I do use NetworkManager and iwd, and they both works fine for me. So I don't know what special reasons may causes NM to not work properly. Your wifi authentication is successful, but failed at association without any useful info.

RinCat avatar Dec 03 '20 01:12 RinCat

Switching the wifi backend in NetworkManager to iwd, restarting NetworkManager, removing existing 'known wifi networks', killing the existing wpa_supplicant, and re-attempting a connection using the wifi settings in gnome control center seems to have made everything work as expected.

jsermer avatar Dec 03 '20 04:12 jsermer

Still unsure why wpa_supplicant works natively, but not via NetworkManager using the default wifi.backend of wpa_supplicant. I can report however, that changing the backend to iwd seems to work pretty well.

/etc/NetworkManager/conf.d/wifi_backend.conf:

[device]
wifi.backend=iwd

I will also note, initially the 2.4ghz band was preferred (2.4ghz signals travel better through walls), but since this is a desktop and doesn't move, I wanted to force the adapter to connect to my 80mhz 5ghz band. iwd made it pretty simple to influence the 5ghz preference by adjusting the following:

/etc/iwd/main.conf

[Rank]
BandModifier5Ghz=2.0

While not technically 'solved', you are free to close this issue.
