Hi, Pretty much all the details and logs are here: refuses to connect to WPA2 secured WiFi https://bugzilla.redhat.com/show_bug.cgi?id=1516009 So I will just include a summary here: Macbook Pro, Broadcom BCM4331 firmware version 784.2 (2012-08-15.... kernels 4.5.5 through 4.13.13 NetworkManager-1.8.4 wpa_supplicant-2.6 Access point is an Xfinity branded Arris TG1682G, 802.11a/b/g/n/ac Connecting to this AP's unsecured "xfinity" SSID succeeds, but fails to its "altitude" WPA2 secured SSID. The user visible failure is either no error other than three dots for the Wifi icon in the gnome menu bar, or more often the modal passphrase dialog for the AP comes up asking for the passphrase again. No other devices (about 1/2 dozen) have this problem, including this same laptop if I reboot to macOS and connect to this same "altitude" SSID with the same entered passphrase. There is an attached log (journal3) where a connection did succeed for a very short amount of time, but then promptly was disconnected with all subsequent attempts to connect failing while the user intervention was zero (I was touching nothing, just monitoring and logging stuff). The journal2 log attached to the bug report contains wpa_supplicant -d output. Let me know if I need to retry with -dd and post that somewhere. Also in the bug are the kernel config options, I don't see any of the requested 80211 options in the reporting bugs guidelines. https://wireless.wiki.kernel.org/en/users/documentation/reporting_bugs So if I need to compile a kernel and enable options, no problem, just let me know which ones. If I change any of the three components: client (the laptop with BCM4331) + linux + AP then the problem doesn't happen. Change the OS and it works. All other devices work with this AP and WPA2. And BCM4331 + linux work with other APs than this one. So it's something of a trifecta bug. -- Chris Murphy
