Cannot return to Ceni from Connman

[rolandMember]

I used Ceni for years with little trouble, but when Connman finally seemed to be stable I changed over to it. However I now believe there is some hidden bug in Connman that causes frequent line dropping, so frequent now as to make it virtually unusable for my circumstances, and I decided on a return to Ceni.

This return however has proved impossible, as I am requested by Ceni to erase a file wlan0 left in /run/wpa_supplicant, which insists on returning the moment I invoke Ceni.

root@antix1:/run/wpa_supplicant#

root@antix1:/run/wpa_supplicant# ls
p2p-dev-wlan0 wlan0
root@antix1:/run/wpa_supplicant#

Password:
root@antix1:/home/roland/Desktop# cd /run
root@antix1:/run# cd wpa_supplicant
root@antix1:/run/wpa_supplicant# ls
p2p-dev-wlan0 wlan0
root@antix1:/run/wpa_supplicant# ls
p2p-dev-wlan0 wlan0
root@antix1:/run/wpa_supplicant# rm *
root@antix1:/run/wpa_supplicant# ls
root@antix1:/run/wpa_supplicant#

Whenever I erase this file, and run Ceni in scan mode, Ceni returns a screen telling me to erase wlan0, and when I look in the folder, there it is again.

It’s almost certainly some error of mine, can anyone point me in the right direction please?

Did you try the easy way first with antix wifi switch?
sudo antix-wifi-switch -c ceni

Hello,

And wether using Ceni or Connman, I don’t see why one or the other would fail. When you say, “line dropping”, is it really the network which is down? Are you using wifi only, and never using Ethernet?

What I have noticed : sometimes, the network would be accessible (a ping to, for example, “www.example.com” would work : “ping -c4 http://www.example.com” outputs 4 lines of returning pings, but the web pages would all be unreachable. I have been using the resolver openresolv many times to replace resolvconf, and it has solved that one issue.

I wonder, is your issue really no network at all?

Hello roland.

I can recommend the video “55 – How to connect to the internet with a wired network (Ethernet) or wireless network (Wi-Fi) in antiX Linux with the Ceni network connection manager? (How to use the Ceni Connection Manager?; How to use the Wi-Fi Manager Program Selector or WiFi Program Selector or “antiX WiFi Switch”?; The Wi-Fi connection fails in CMST ConnMan what do I do?; How to switch between antiX network managers?; etc.)“.

Hello,

Maybe a few simple command lines can also help, with getting a connection, for starter.

This one will provide all information on the network cards that are up:

ifconfig

Then, you will see which ones are ‘up’, and if you want to remove wlan0, it is not with the “rm” command. It would rather be as root :

ifconfig x down

where “x” is the name of the card interface that you want out of the way (as I understand, “wlan0”). To check the result, you can invoke “ifconfig” again. To revert back, use “up” instead of “down” with the network card interface available that you want to use.

If you want to just connect to internet with one command line:

dhclient x

where “x” is still the name of the network card interface (found with the “ifconfig” command line). And just:

sudo dhclient

(or “su”, then “dhclient”) without argument works too. It will use the available network interface.

I just tested it all in a VM where I started antiX 23.1 runit full.

Marcelocripes video was a good one and I caught something I never thought much about before: (I’ve switched to Ceni myself since I don’t connect to anything but ethernet or my own wifi router)…

Total conjecture: I wonder if anyone using Ceni having these line-dropping issues might consider to change from the default of “hot plug” to “auto” (which is for stay-in-place internal devices..)

In other words, on my machines, unless I’m using a usb wifi-dongle, I’ve changed the defaults when I first set up to “auto”, not hot-plug.

I’m not having the issue, and again, this is total conjecture. It did work in my situation, so I’ll probably just leave it like that.

Many thanks to all contributors, there’s quite a bit to think about in your responses, I’ll go through them one by one.

I ran across this before as I move sticks around to different desktop machines with Ceni.

Ceni has an option you can chose to make it forget the current configuration. And then you can instruct it to reconfigure. So no manual deleting of files.

In fact, for my wifi-only desktop machines, I tell it to simply remove the configuration for ethernet, so it doesn’t sit there for a long timeout when I reboot.

But yes, Ceni is mind-numbingly slow when first configuring wifi as it steps through the channels of a dual-band wifi card! 🙂 So for laptops, I use Connman. But maybe this will help.

Thanks for all these suggestions, but they did not take me forwards. I would revert to Wicd if it were available but is is no longer in the software install lists. Anyone know how I can install it? It was withdrawn I hear due to large memory requirement, but with 64g I have no problen there.

Try

apt search network-manager

How to Search for AntiX solutions to your problems

[rolandMember]

I am pleased to report this problem resolved, along with my previous reports of persistent wifi line dropping by Connman.

I spent some time on the www following the sound suggestions by Rokytnji about helping onesself to find solutions, and came across a warning to avoid having multiple network managers installed, which was my case. I uninstalled everything network related except Connman and Ceni, which for some reason is harmless in this context being merely a collection of scripts I think, ran a cold reboot, and have not lost my line since then. I will be monitoring progress but so far the author of this warning has an additional admirer. Thanks and best wishes!
