      I have installed Antix on my old Acer 3023WLMi, and I am quite happy with the OS performance. The laptop had been previously running Debian 11 with LXQT and it was visibly slower.
      There is one major problem though, and it is the Broadcom BCM4318 WiFi. Connman says it is connected, but I can not access anything. I have to say that the last official 32bit Puppy linux works well with the laptop’s WiFi.

      During the Antix installation, the b43-fw_cutter, firmware-b43-installer, firmware-b43legacy-installer have been installed. I have removed firmware-b43legacy-installer, as it is not relevant for the 4318.

      After a re-scan, Network assistant has shown the following loaded drivers: b43,r8169,mii,fjes

      ping fails, with message “Destination Host Unreachable”. The same message appears whenever I try to use a browser to access Internet.

      ping works fine.

      I have attached the output of several commands.

      The file /etc/network/interfaces has also just two uncommented lines:

      iface lo inet loopback
      I have also followed the steps advised on B43 thread found in the Antix Forum:

      1. sudo rfkill unblock all
      2. sudo apt purge firmware-b43-installer
      3. sudo apt update
      4. sudo apt install –reinstall firmware-b43-installer
      5. sudo modprobe -r b43
      6. sudo modprobe b43

      Unfortunately, nothing has changed.

      Have to say that my laptop has been working relatively fine for several years with Debian. After the last Debian update the Wifi stopped working and this was the reason to move to Antix.

      Another detail is that when I move my Wifi connection to the top of the Connman list of Services, the connection begins to work for a while, albeit at a really slow speed. After about 1 minute, the connection is lost again.

      This problem is way outside my experience and I would be grateful for any help.

        I wonder if the Ceni network manager would have different results.

        I’ve had a few cases where it’ll solve things and sometimes switching between connman and ceni help; the switching network topl can be helpful for this kind of switching back and forth; sometimes it helps identify or magically solve networking issues.

        As far as the Broadcom commands, yes, those are accurate.

        If you can throw a few dollars at this, sometimes grabbing a removable USB wireless antenna/adapter helps but be careful to choose one that has a well supported card that works well with Linux so that you have a working solution.

          Dear aspire3023,
          I experimented your issue in December 2021 when installing antiX on an Acer from 2007, and I found that the solution proposed in the top of the forum was optimal for me.
          The same issue was detected in a lot of Debian derivatives such as Mx, Q4OS, Sparkly, etc and NOT on the *buntus => the issue lies in Debian and not in antiX.
          The forum solution worked both on antiX 19 and in 21.
          In some cases, with antiX 22, some problems with Connman are reported, and @Brian Masinick in the previous post pointed you to a solution.

          As a 1st step: I’d search using a live with 21, to verify if the forum solution works.
          Don’t forget to do : “sudo apt update” before following the 6 steps.
          In this case you need another way to be connected to internet: in case your internet connection is done with another wifi dongle or an eth cable, you can immediately test if the forum solution is good for you.
          In case your internet connection is done using your mobile phone, usb connection, unfortunately you should reboot your Acer in order to see if your b43 now works. In this case you should make your live try, using the root persistence.

          As a 2nd step: now you know if your b43 is working or not, if it works now you can try on antiX 22 as now you will have located your problem.

          Good luck 🙂

            Did you look at the thread up near the top about Broadcom WiFi?

            Maybe you didn’t notice it above. Here is a link…


            my bad, I bet that is the thread you referred to…

            PS: I fired up the old Dell D620 laptop I have, and it has a Broadcom 4311, so everything isn’t identical.

              I am guessing Debian (or upstream of them) maybe changed something which affected your card, and that code is used by antiX as well. I would suggest you try an older version of antiX, but don’t update it before you install. My 4311 had trouble running from antiX off the flashdrive, but worked ok once installed to the hard drive. Maybe the 4318 will have the same issue.

              PS: If you get it working at good speeds let us know, please. My 4311 has gotten much slower. BTW, the best answer I found so far was to add a separate wifi adapter.

                Many thanks for all of your helpful replies.

                I have bought a TP-Link TL-WN722N wireless USB adapter. It began working immediately after I had plugged it in. There was a user panic after the first reboot, as the adapter was shown as connected to my wireless service, but again there was no internet connection. Luckily, moving the connection to the top of the Connman services solved the problem. The connection was fast and stable. So the only minor annoyance left is that after every reboot, I have to manually start the Wifi connection, which is OK with me. This was not an option with the latest version of the b43 driver, as the laptop was losing connection shortly after gaining it.

                Then, I have removed completely b43 related software from my laptop and reinstalled an older version of the firmware-b43-installer.

                $sudo apt purge *b43*    
                $sudo apt list -a *b43*  
                $sudo apt install firmware-b43-installer=1:019-3

                After that, I have rebooted my laptop and manually pushed my WiFi network to the top of Connman services. This time, the connection provided by the BCM4318 was stable and its speed was acceptable. Still, the TL-WN722N USB adapter seems faster, than the old BCM4318.

                Many thanks again!


                  Glad to hear it worked. Thanks for posting the solution. I’ll give it a try on my 4311. Its pretty similar.


                    Dear aspire3023,
                    I’m happy that you could find a solution.

                    Still, the TL-WN722N USB adapter seems faster, than the old BCM4318

                    To me happened the same: using the native B43, the max speed arrived to 20Mbps (average 10), while with the TP-link it was easy to arrive > 35 Mbps.
                    In any case, my needs are not so high, so I ended up using the internal wifi, being happy that way.


                      I downloaded Debian 11.5 and tried to install it on my Dell D620 with the Brcm4311 wifi, and B43 does come up on the list to select it, but it doesn’t recognize the card, and won’t install.

                        Isn’t it interesting; a decade ago that same hardware could run almost anything and in it’s prime it was an excellent laptop.

                        Dell, IBM/Lenovo and HP equipment has always worked well for me and I have had pretty good results with Gateway and Acer too.

                          Hi BobC,

                          You may have already checked it and tried it, but BCM4311 is also supported by the wl driver in broadcom-sta-dkms package.
                          Also, during my first Debian installations, I had to complete the installation without the WiFi drivers. I had to download the drivers on another computer, and then I have copied and installed them on my acer 3023.

                          I have followed the installation procedures for the bcm 43xx drivers shown here:

                          And the for the wl driver you may check this link as well:

                          As we had already commented above, after the last Debian 11 update, I had to use the previous version of b43 package 1:019-3, because the latest 1:019-7 provided by the installer didn’t work. It may be the same with the broadcom-sta-dkms package. I do not know how you can choose a previous/older version of a specific driver during the Debian installation though.


                            I will look into it and also try the solution you used. I was looking, and there was a bug reported in 2012 that affected machines with 2 Broadcom adapters, which mine has, and it doesn’t look like it was ever fixed.



                              I had a similar issue installing MX Linux 23.2-386 on a HP Pavilion ze2000. The issue was present booting from Live-USB as well as booting from a fresh installed system. The WiFi access points were visible but I could not connect to any.

                              The 6 steps procedure described in the first post worked like a charm, on live system and installed system. I just had to retype the step-4 command due to a syntax mismatch. The “reinstall” parameter must be preceded by two “-” (not the strange “–”).
                              sudo apt install --reinstall firmware-b43-installer

                              Thanks to @aspire3023. Resurrected this antic but useful comp.

                                The incorrect dashes in any command copied is due to the way in which certain characters are interpreted in the text widget of the forum software — is correct – or _ is incorrect, as is some graphical display of dashes instead of –, so you were correct in fixing this.
