Broadcom wifi dies in 60s cycles with 4.8 kernel

[Leonardo]

I have a Dell XPS 13 9350 with a Broadcom wifi adapter. Wifi connects fine, but dies for around 5-10s (the signal dies completely, tools like wavemon show "no interface data") in regular cycles of about 60s. dmesg logs the same brcmfmac errors every minute or so: "brcmfmac: brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)".

network-manager's icon doesn't change however (remains as if the adapter was connected).

This issue started to affect me when using kernel 4.8 on Ubuntu 16.04. I previously used kernel 4.7 and did not experience this bug.

I booted the 16.10 daily build and experienced exactly the same errors.

I've got the same issue with my Dell XPS-15 (9550). The chip is BCM43602.

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

And the problem is almost gone. The connection is fast and stable, but I still getting error about ISO code.

[Christophe de Dinechin (i-christophe)]

I have a similar issue with Mac Book Pro 15", with only one of my two base stations, the other one seems to work fine.

The base station that fails is a Freebox Revolution, configured to use channels 12 and 8 with 40MHz bandwidth in 2.4GHz mode (according to its configuration page).

The base station that works (same SSID, same password) is an old Airport Time Capsule.

When I attempt to connect to the Freebox Revolution, I get a stack trace:

[Rohin Gopalakrishnan (rohinrohin)]

Is there a fix or a temporary fix expected for this issue? I'm unable to use my system without an external dongle on any Linux system.

Any help is appreciated.

[Kai-Heng Feng (kaihengfeng)]

Does newer or older Linux kernel work without this issue?

Is the issue linked to "brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)"?
I can see this message popped out several times, but the network is still connected.

[Chris Sanders (chris.sanders)]

This appears to be a conflict with the Nvidia driver (at least for me).
I've tried:
nvidia-378 (open source)
nvidia-370 (open source)
nvidia-375 (proprietary)

All three give the exact same results as above on both 2.4 and 5 Ghz. Switching to the intel graphics driver completely clears this up. It's not a great work around for me as the Intel in the XPS-15 (9550) chokes on an external 4k display with chrome. But it's functional when I need to switch to wifi (which I'm generally not connected to an external display with)

[Chris Sanders (chris.sanders)]

I've just noticed this has resolved for me. See below, the errors do not repeat and I connect to the network. However, I have recently updated my router firmware to my knowledge it's still configured like it was (40/80 Mhz channels). I'm running the same nvidia-375 that was causing errors before.

[Leonardo (lbrito)]

I am no longer experiencing this error; however, now the network-manager applet does not load at all and I am only able to connect to open (i.e. with no authentication) or previously-configured closed wifi networks (through Settings -> Network).

I am unsure as to what caused this new error, since I don't remember when exactly it started. I will possibly open a new bug for this.
