Hello everybody. I have a Dell XPS13 with a broadcom wifi adapter. It worked perfectly, but all of a sudden Network Manager stopped detecting networks. I have no clues about what can be the cause, but when I click on "Connect" in network manager it hangs there forever and does not find any network. As I can regularly connect to the wifi with the same computer when I boot in Windows, the problem is neither the card nor the wifi. Any suggestion?

I maybe because there was an update of the kernel, therefore the kernel module for your wifi card need to be recompile, try using your machine with older version of the kernel, from the list at boot

I am using iMac Pro and I recently started using it. Actually, I can see that the Network Manager is not able to detect the Wi-Fi. It is not finding any network. I tried to contact about this issue. I tried many times to connect but couldn't get rid of this issue. So is there any suggestion available to fix this issue?

Anything different you did today compared to yesterday? Can you find out a potential solution for future reference?

dkms vrs akmod; ironic... UnitedRPMs maintains a broadcom dkms (broadcom-wl-dkms); Thus I have my Broadcom (BCM43142) working perfectly with the kernel 4.17.6-200. Some underestimate UnitedRPMs; but here exist, hard job... This works for me, and many people ...

Thank you. It does not seem to be a problem with the kernel: when I boot with an older version (4.16.5-300 as opposed to 4.16.12-300) the problem is still present. I doubt is a problem with akmod: right out of the box, the card was not recognized and I could not see the wifi entry in Network Manager; then I installed broadcom-STA and akmod and after that everything was fine. Now the entry is there -- so the card is recognized -- but it just fails to detect available networks.
