I believe this is similar to the issue im getting with my BCM43602 on macbookpro running 16.04. It worked fine on 15.10.
Ive updated to the upstream xenial kernel but the bug still exists : $uname -a Linux <redacted> 4.4.9-040409-generic #201605041832 SMP Wed May 4 22:34:16 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux $lspci | grep -i wire 03:00.0 Network controller: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC (rev 01) $dmesg | grep -i brcmf [ 10.242291] usbcore: registered new interface driver brcmfmac [ 10.381196] brcmfmac 0000:03:00.0: Direct firmware load for brcm/brcmfmac43602-pcie.txt failed with error -2 [ 10.864481] brcmf_c_preinit_dcmds: Firmware version = wl0: Nov 10 2015 06:38:10 version 7.35.177.61 (r598657) FWID 01-ea662a8c [ 10.892497] brcmf_cfg80211_reg_notifier: not a ISO3166 code [ 10.897532] brcmfmac 0000:03:00.0 wlp3s0: renamed from wlan0 [ 10.968018] brcmf_add_if: ERROR: netdev:wlp3s0 already exists [ 10.968051] brcmf_add_if: ignore IF event [ 11.080205] brcmf_add_if: ERROR: netdev:wlp3s0 already exists [ 11.080208] brcmf_add_if: ignore IF event -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577113 Title: 50/50 chance for BCM43602 to come up correctly during boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577113/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
