I can confirm the issue affects the MBPr 12,1 as well. I've also noticed that when going to suspend/hibernate that exactly 60 seconds after resume the whole system will lock up if brcmfmac is loaded. Not sure if this is related or not. Manually running rmmod brmcfmac before suspend, then modprobe brcmfmac afterwards results in me being able to see wireless networks but oddly enough not my own one via network manager. using wifi-menu/netctl I was however able to see and connect to my network. Sorry for double post. When restarting networkmanager it spews out the following kernel trace (again, this is only post-resume from hibernate/suspend): https://gist.github.com/justin8/484464641fae604799bd Also 5 GHz doesn't work, and the correct physical MAC address isn't recognised properly, everyone with this card (14e4:43ba) gets assigned the MAC address 00:90:4c:0d:f4:3e. Even by spoofing MAC address, it isn't possible to have two users of this card in the vicinity of each other. This issue has been root caused as a firmware issue. We are preparing a new firmware release to linux-firmware repo. (In reply to Arend van Spriel from comment #5) > This issue has been root caused as a firmware issue.

The 60 seconds suggest firmware loading using some timeout. Do you have the brcmfmac driver built-in the kernel or using it as a kernel module? It is a module.

Do you have the > brcmfmac driver built-in the kernel or using it as a kernel module? I had the 60s to load problem when I was compiling the linux-mainline package on ArchLinux, I think it only happens when the kernel is running with debug enabled? I'm not getting it with the linux 4.2.0-4 package from the testing repo, and I wasn't getting it with 4.1.6 from core either. Prompted by Adrian's comment, I enabled Arch's testing repositories and enabled its kernel. I can confirm that fixed the 60s to load problem on my machine. I can also confirm the testing 4.2.0-4 kernel in arch's testing repo fixes the 60s to load issue. The MAC address is still forced to 00:90:4c:0d:f4:3e however. And I do not appear to be able to see or connect to 5GHz networks still. But they existed in 4.1.x as well; so the regression is fixed? but networking is still fairly broken. Please try latest firmware in linux-firmware repository [1]. Regards, Arend [1] https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/brcm/brcmfmac43602-pcie.bin?id=ea1178515b8852a5ead23b165b4609ef2b49f36c I found that one 2 days ago, I've been using it for a full day now and it's working great! Thanks Running 4.4.2 on Dell XPS 13 (2016) with latest brcmfmac4350-pcie.bin from linux-firmware repo and I get the timeout still: [ 74.153278] brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Oct 22 2015 06:16:26 version 7.35.180.119 (r594535) FWID 01-e791c176 [ 74.169784] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code Is there an updated firmware for this chipset?

I'm having the same issue with my last dell xps 13 (2016) laptop since last update... How can I do? Have the same 60s problem (on MacBookPro 11,5).

I tried the firmware blob as described here plus from linux-firmware (git), but that crashes instantly the kernel (could not debug it further att) when try to load. I'm on Gentoo (with gentoo kernel patchset) and not know if the guys here have modified something related. best regards, Niels. I also touched this problem in Dell XPS-13, with Fedora 24 system.

Same issue here. Dell XPS 13 9350 with Broadcom Corporation BCM4350 802.11ac Wireless Network Adapter [14e4:43a3] (rev 08). I'm using Ubuntu 16.04 with the 4.8 kernel. brcmfmac errors are logged in dmesg every 60s or so: [ 449.586402] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30) [ 517.154683] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30) [ 582.704065] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30) [ 650.273411] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30) And when the error happens, wifi dies for ~10s. This issue did not happen with me when using kernel 4.7. I also experience this issue on a MacbookPro 12,1.

[ 52.135162] brcmfmac: brcmf_inetaddr_changed: fail to get arp ip table err:-23
Just an update:
I'm on a new kernel 4.8.1 with linux-firmware 20160628 (Gentoo) with no change. After loading the brcmfmac module it takes a minute until upcoming with the network device. Same happens when rmmod and insmod the module again. Seems it run's into any timeout while firmware loading or similiar.

New elrepo kernels should have this. See http://elrepo.org/bugs/view.php?id=671. I ended up swapping the wireless card for an Intel one. Easy and works great. I've flashed my router (Archer C7 v2) with dd-wrt (ftp://ftp.dd-wrt.com/betas/2016/11-01-2016-r30826/tplink_archer-c7-v2/), configured 5Gz network as follows: Wireless Mode: AP Wireless Network Mode: AC/N-Mixed Channel Width: Full (20 MHz) Wireless Channel: 40-5200 MHz The connection is fast and stable, but I still getting error about ISO code. I see a systematic driver crash on a Mac Book Pro 15" running Fedora 25 Workstation, following the same "not an ISO3166 code" message. It only happens when connected to one of my two base stations, a Freebox Revolution. As far as I can tell, 5GHz is not enabled on that base station (the configuration page says it's using a 40MHz bandwidth at 2.4GHz, channels 12 and 8). It happens every time I enter a Wi-Fi password. From a user perspective, it looks as if the Wi-Fi password was bad, there is no notification other than in dmesg. The other base station is an old Airport Time Capsule, and there is no issue connecting to it. The stack trace is: [ 1008.652836] brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30) [ 1011.548069] ------------[ cut here ]------------ [ 1011.548099] WARNING: CPU: 2 PID: 2262 at net/wireless/sme.c:724 __cfg80211_connect_result+0x3ab/0x410 [cfg80211] [ 1011.548100] Modules linked in: rfcomm fuse nf_conntrack_netbios_ns nf_conntrack_broadcast xt_CT ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 xt_conntrack ip_set nfnetlink ebtable_nat ebtable_broute bridge stp llc ip6table_mangle ip6table_nat nf_conntrack_ipv6 nf_defrag_ipv6 nf_nat_ipv6 ip6table_raw ip6table_security iptable_mangle iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conntrack iptable_raw iptable_security ebtable_filter ebtables ip6table_filter ip6_tables cmac bnep nls_utf8 hfsplus intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel btusb snd_hda_codec_cirrus snd_hda_codec_generic snd_hda_codec_hdmi brcmfmac kvm btrtl btbcm btintel joydev bluetooth brcmutil snd_hda_intel snd_hda_codec applesmc cfg80211 iTCO_wdt irqbypass iTCO_vendor_support input_polldev [ 1011.548128] snd_hda_core crct10dif_pclmul mmc_core crc32_pclmul snd_hwdep snd_seq ghash_clmulni_intel intel_cstate intel_uncore mei_me intel_rapl_perf bcm5974 snd_seq_device rfkill mei i2c_i801 snd_pcm i2c_smbus lpc_ich thunderbolt snd_timer snd soundcore shpchp sbs sbshc acpi_als apple_gmux kfifo_buf industrialio video tpm_tis tpm_tis_core tpm apple_bl nfsd auth_rpcgss nfs_acl lockd grace sunrpc uas usb_storage hid_apple btrfs xor amdkfd amd_iommu_v2 radeon raid6_pq i2c_algo_bit drm_kms_helper ttm crc32c_intel drm fjes [ 1011.548154] CPU: 2 PID: 2262 Comm: kworker/u16:9 Tainted: G W 4.8.14-300.fc25.x86_64 #1 [ 1011.548155] Hardware name: Apple Inc.
