Wi-Fi works for MacOS, but sporadic on Kubuntu
Hello all, I have a 2013 Retina MacBook Pro, and I just recently started seeing a strange network issue with it.
I am using a Netgear WNDR3400 as my Wi-Fi router, and it works great for my MacBook when I'm booted into MacOS, but my ping times are sporadic and often outrageous when I'm booted into Kubuntu.
Both MacOS and Kubuntu can only see b/g/n networks created by the router, so that's what I'm using for both.
My network security is WPA2-PSK [AES].
I can log into the network just fine on both MacOS and Kubuntu.
When booted into Kubuntu, my network connection will sporadically drop entirely, or my ping times to 8.8.8.8 will go up to thousands of milliseconds.
It will even get to the point that I can't even reach the router at its IP address, so the issue is not my modem or internet connection.
It typically comes back after a couple minutes, but it might go to poop again within seconds or minutes. Impossible to predict.
I assume this is a Wi-Fi driver issue?
I have never bothered to install Wi-Fi drivers on my MacBook. I have always just left an Ethernet cable plugged in during install of the OS, and let Kubuntu sort out what it wants/needs for itself. It's never behaved strangely until today, but I wasn't paying much attention to what recently got updated.
I followed the directions here to the letter: https://askubuntu.com/questions/5586...reless-drivers
No change. Still being ridiculous. I followed the instructions for Special Case #3 - For the 14e4:43a0 rev 03, and below is the result.
Hot garbage.
Further down the instructions page, it says, "IMPORTANT NOTE - After September 2014, if you follow this answer and still you have problems installing the correct driver, please try the firmware-b43-installer package and the linux-firmware package."
Well, when I try to run
I get
If I google that error, it takes me to the same page suggesting I just sudo apt install firmware-b43-installer
I'm running around in circles here.
