List of some current Buster CLI WiFi commands?

[DKCorl]

I'm having real hard time trying to sort out a USB WiFi. Think I'm missing some of the needed to get it going.

Seems most of the searches I try pull up older commands that are not on my system.

Got to shutdown - another lighting storm coming.

rfkill tool for enabling and disabling wireless devices
nmcli command-line tool for controlling NetworkManager
iw show / manipulate wireless devices and their configuration
iwconfig configure a wireless network interface
iwlist get more detailed wireless information from a wireless interface
iwspy get wireless statistics from specific nodes
iwpriv configure optionals (private) parameters of a wireless network interface
iwevent display wireless events generated by drivers and setting changes

Drivers or firmware are the usual suspects for non-working wifi. Identify the chip in your device and search for solutions.

lsusb should show your device.
Example from mine:

Code: Select all

Bus 007 Device 002: ID 0cf3:7015 Qualcomm Atheros Communications TP-Link TL-WN821N v3 / TL-WN822N v2 802.11n [Atheros AR7010+AR9287]


Take the 8 numeral ID and search like "linux 0cf3:7015"

In my case the driver is in the kernel but I needed to install firmware-atheros to get it working. Sometimes you need to find and build a driver as well. And occasionally you just need to get a different device. Lotsa luck!

Thanks for the info. The best that I can see is there is no wlan0 setup or loaded and so far I can't figure out why.

Thanks for the reply. The best I can see is the firmware is getting loaded. I have a raspberry pi zero that is based on Buster that is working perfect on WiFi so I have been comparing. Below are some commands and the output from both the pi and the desktop.

Looks like the wifi device on the desktop is called wlx9cefd5fca3d6 not wlan0 (don't know why) and it is disconnected (don't know why).

Try this

Code: Select all

nmcli -a con up id wlx9cefd5fca3d6

[DKCorl]

Found and ran some more commands with interesting results but still no WiFi. Also found iw and some other commands are not in the path and won't work unless I add /sbin.

When I check my router client list I do not see the wifi connection from Buster.

[sunrat]

Try the solution in the last post here - https://forums.bunsenlabs.org/viewtopic.php?id=5032

Basically, check it's unblocked with rfkill and maybe disable MAC address randomisation.

[ruwolf]

Try this

Code: Select all

nmcli -a con up id wlx9cefd5fca3d6

wlx9cefd5fca3d6 is not their connection name, but device name.

[DKCorl]

Looks like I'm going to have to take a break on getting WiFi working. Got as far as:
root@Buster:/home/dkc# nmcli device wifi list
IN-USE SSID MODE CHAN RATE SIGNAL BARS SECURITY
CoreDump Infra 3 54 Mbit/s 84 ▂▄▆█ WPA2

But when I run:
nmcli dev wifi con "CoreDump" password "mypassword"

I get an error:
Error: Connection activation failed: (53) The Wi-Fi network could not be found.
root@Buster:/home/dkc#

If you really don't have any GUI layer installed (plasma-nm for KDE) to make things easier, you can use nmtui which is the n-curses application of network-manager, and should clarify.

[DKCorl]

Update - got it working. Perhaps because I installed using the smaller CD image instead of the DVD or Net-install and or because there was no WiFi adapter installed in the computer when I first installed Buster I had no front end to the network-manager. Tried to bring up the WiFi adapter using the nmcli from root in a terminal but could not get the syntax correct. It was only after I installed WICD, unplugged the wired Ethernet and forced WICD to connect to my WiFi router that I got it to work.

BTW - I did think the Panda PAU05 was supported by linux. The listing on amazon said over and over it was but it does use the non-free firmware. Will cross post this in the other post I started on WiFi.

Thanks for all the help and ideas
