Intel Dual Band Wireless AC 7260 randomly stops working.

Hey all,

I have an Intel Dual Band Wireless AC 7260 (Desktop edition) that randomly stops working. The only thing that will fix it is rebooting the machine. I've googled a bit and can't find anything that worked. Hopefully someone here knows what can cause this and how to solve this.

Thanks in advamce!

My kernel information:

Linux dijkstra 4.13.8-1-ARCH #1 SMP PREEMPT Wed Oct 18 11:49:44 CEST 2017 x86_64 GNU/Linux

My firmware information:

The errors in the log when it happens:

Re: Intel Dual Band Wireless AC 7260 randomly stops working.

Nobody has the same issue? This is really annoying and I really have no idea how to fix it.

Does

iwconfig

Show power management on?

Re: Intel Dual Band Wireless AC 7260 randomly stops working.

Same issue here. Actually I'm not using Arch but Fedora but I guess that's still a useful data point, especially as I could only find a single other mention of that message, "solved" by replacing the hardware. Mine also started acting up yesterday. As my son had just dropped the laptop I put it down to a hardware problem (loose contact or so) at first but being that it just came up for both of us, software sounds far ore likely.

My kernel version:

Linux 4.13.9-200.fc26.x86_64 #1 SMP Mon Oct 23 13:52:45 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

HW is a ThinkPad T540p, kernel messages are almost identical to yurs:

[   10.468831] iwlwifi 0000:04:00.0: loaded firmware version 17.459231.0 op_mode iwlmvm
[   10.549833] iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x144
[   10.568634] iwlwifi 0000:04:00.0: base HW address: e8:2a:ea:00:b3:e7
[   10.773680] ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs'
[   10.780216] iwlwifi 0000:04:00.0 wlp4s0: renamed from wlan0

The driver version is from linux-firmware-20170828-77.gitb78acc9, apparently the version is from September 20th. Which is strange because even though I rarely reboot the laptop unless there's a critical update, I have definitely done so a once or twice times this month.

@jeremy31: yes, PM has generally been on in my case. Just switched it off, it's been running for half an hour now ...

I'll report back if I find any clues.

Yeah, I disabled it, let's see if that helps. The weird thing is that this a recent problem.

I'm afraid there's not much you can do
