Arch Linux

Same issue here. Intel 8265. 2.4GHz seems to be OK, but trying to connect via 5GHz repeatedly fails with "No beacon heard and the time event is over already". I'm not sure which exactly update broke it, but it was something fairly recent.

I'm facing the same issue, I've configured the modprobe options for iwlmvm and iwlwifi but there were no luck at all.

$ cat iwlmvm.conf
options iwlmvm power_scheme=1
$ cat iwlwifi.conf
options iwlwifi bt_coex_active=0 11n_disable=1 swcrypto=1

Same issue for me with an Intel 7265, on a lot of networks (both 2.4 and 5GHz). The deciding factor seems to be the channel used. Also not sure which update caused the issue, tried a couple of old versions but couldn't succeed.

So far, it seems to be fixed for me on the latest updates (linux 4.16.11-1 and linux-firmware 20180518.2a9b2cf-1)

I have problems while connecting to my Oneplus 5T phone hotspot. I didn't use it frequently. Approximately one month ago i used it, and it worked fine.

I tried 2,4Ghz and 5Ghz. Changed the SSID. Without WPA2 security the connection established. After change the WPA2-PSK, the connection established, too. But next day, i had problems again.

i still have problems.

core/linux 4.17.11-1

I spoke too soon - it's definitely still an issue for me as well. Results seem to vary depending on the AP and band used. On some APs, I can't connect via 2.4GHz at all but 5GHz works fine.

linux-firmware 20180825.fea76a0-1
linux 4.18.12.arch1-1

Upgrading from 4.14 to 4.16.18_rt12-1 fixed the issue for me.

Hi Vito,

A few questions:
- Which version of linux-firmware do you have?
- Are you running Manjaro? Or did you use a Manjaro kernel package on Arch?
- What patches are applied to that kernel? Do you have a link for the kernel PKGBUILD and any patch files that go with it?

linux-firmware-20180825.fea76a0-1

I am running Manjaro. I am not sure how to identify which patches have been applied to the kernel. I installed the 4.16 realtime kernel on October 19th. I insalled the kernel via the GUI Manjaro Settings Manager's Kernel tool, I am unsure of how to get the PKGBUILD/patch files.

I forget if happened in 2017, but this year(2018) when I try to connect to 2.4G or 5G wifi, it reports these and it's hard to connect to the wifi

Sherlock - what versions of linux and linux-firmware do you have?

So far I'm having much better results with linux-firmware 20181018.d877533-1 and linux 4.18.16.arch1-1. I'm not ready to call it completely solved yet, as I've been wrong before. But it's working fine on a 2.4GHz AP that I couldn't connect to at all before.

I have found a new clue that might help explain some of these issues. I discovered that if I am already connected to a wifi network, connecting to another network often fails. However, if I first tear down the current connection and then connect, it works fine.

For example (using network manager):
- start connected to SSID_A
- run: nmcli con up SSID_B
- connection fails with "No beacon heard and the time event is over already..."
- eventually, it aborts and connects back to SSID_A

vs

- start connected to SSID_A
- run: nmcli con down SSID_A; nmcli con up SSID_B
- successfully connects to SSID_B

Have the the same issue.

Connecting from a known network to a known network fails.

but connecting from a known or no network to a new network succeeded.

A workaround is to delete the current active network and then connect to the new one.

I am also affected by somehting similar. Where should I try to test solutions? Happy to help but the programming here is a ways beyond me.

I have a similar problem here, with linux-firmware 20190313.efd2c1c-1

However, I can connect to a new SSID after rebooting the computer.
It seems that I cannot connect to a new SSID after the computer waking up from sleep.

I am affected as well.
I am able to connect to 2.4GHz network without problems, but I cannot connect to a 5GHz WiFi on the same router, with the same authentication if I have been already connected to the 2.4GHz network. The only way to do disable autoconnect, reboot and manually (in NetworkManager GUI) connect to the 5GHz network.

The error is:
kernel: iwlwifi 0000:02:00.0: No beacon heard and the time event is over already...

My hardware is:
02:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)

Since yesterday, I see this issues on 2 different devices, on a Thinkpad T450s with "older" iwlwifi and also on my primary Thinkpad P50.

I can connect fine to a 5GHz network, but not anymore to a 2.4GHz network.

2 other devices a x220 (running windows) and a x230 (running current ubuntu) are connecting fine to the same wifi, so i think it's something broken with the module/kernel?

I see the error:

kernel: iwlwifi 0000:03:00.0: No beacon heard and the time event is over already...

My hardware (on the thinkpad p50) is:

linux-firmware 20190424.4b6cf2b-1

I also have this problem on a t540p. Mail me in case you need more info/someone to test.

It seems to have become better when I changed "Beacon Interval" from the default 100 ms to 50 on my AP. So far no disconnects in three days.

**EDIT**: Can confirm, the problem appears to be fixed after this change.

Interesting re beacon interval change, info about the AP WiFi, fw, hostapd, wpa supplicant, could be useful @andreyv. My guess is this is not related to Intel clients, more to do with the access point. In my case ath10k

AP is TP-Link TL-WR841ND v7 (Atheros AR7241) with OpenWrt 19.07.0 (hostapd 2.9). From the logs, these errors started happening regularly around May last year.

I am suffering this too on my 9260AC.

[ 1719.810647] iwlwifi 0000:21:00.0: No beacon heard and the time event is over already...
[ 1719.810659] wlo1: Connection to AP XX:XX:XX:XX:XX:XX lost
[ 1719.836953] iwlwifi 0000:21:00.0: expected hw-decrypted unicast frame for station.

This wifi adapter is a pain in the ass.

Some intel folks are working on this over at https://bugzilla.kernel.org/show_bug.cgi?id=203709. But there are some issues collecting trace logs from users with the issue.

I've had this issue for a while, but it's very intermittent so it's hard for me to capture a trace. If anyone here experiences this issue with some frequency, or if you know of a reliable way to reproduce, I think it would be a great help if you could follow the instructions in the bugzilla link to capture a trace, and apply the patch in comment #28 if you are able.

Had been facing the same disconnects (every few minutes) since I replaced a Qualcomm WiFi card with an AX200 on the other day. Using 5.3, getting the same "No beacon heard and the time event is over already" messages and often failing to authenticate as well. After resuming from sleep, it was almost impossible to have working WiFi even for a few minutes, requiring a reboot but also facing new issues after a few minutes. However, I have fixed the issue by disabling ipv6 for the WiFi connection in NetworkManager and setting the 5GHz network in the AP to a fixed (39) channel, as I've seem somebody suggest in some other forum. Haven't noticed a single disconnect/issue ever since, even after resuming from sleep.

I provided a lot of logs here: https://bbs.archlinux.org/viewtopic.php?pid=1901025#p1901025 with a raw wpa_supplicant, it's a really painful experience... I can't resolve that, tried really hard. I wasn't experiencing this in the past on the same hardware and connection AP, so I suspect it's in the latest versions of the kernel. None of the suggestions above has worked, like removing ipv6 support (on any level), swcrypto switch, fixed channel...

Basically, what I see, is a success until out of nowhere, "iwlwifi 0000:04:00.0: No beacon heard and the time event is over already..." happens and connection is lost:

I'm experiencing the same issue with an Intel 3160 adapter, it seems to go into a connect-disconnect loop once in a while.

This happens on my machine as well.
Just like justincapella (https://bugs.archlinux.org/task/58457#comment185620) my conclusion is that the ath10k station is at fault.
ath9k stations don't produce this problem.

Connections break also for other devices (including Apple/Android).
To me, this doesn't look like an issue with Arch Linux but an issue with ath10k/openwrt.

The workaround suggested by andreyv (https://bugs.archlinux.org/task/58457#comment185619 - reduing the beacon interval to 50) doesn't resolve the connection issues on my end.
Changing the channel (https://bugs.archlinux.org/task/58457#comment186636) also has no effect for me.

I'm starting a discussion in the openwrt forum.
https://forum.openwrt.org/t/wifi-connectivity-issues-with-ath10k/67779
I've tried a few combinations of openwrt trunk/19.07 and ath10k stock/candelatech for the access point. There were working versions with openwrt-trunk + ath10k-ct and some with openwrt-19.07 + ath10k.

I mailed the ath10k list awhile back about this but didn't get much traction:ath10k@lists.infradead.org/msg11599.html"> https://www.mail-archive.com/ath10k@lists.infradead.org/msg11599.html

I think it's a weird timing thing maybe we're seeing more frequently now that airtime fairness queues are default. I think it may be fixed in hostapd, but that maybe some queued packets are not destroyed on disconnect

I'm having the same issue with rtl8188ee.

AP:

https://openwrt.org/toh/asus/rt-ac58u currently running OpenWrt 18.06.4 r7808-ef686b7292

Beacon interval is set to default (100). I started seeing disconnects after a recent kernel upgrade this month. Setting the following modprobe options seems to work so far:

options iwlmvm power_scheme=1
options iwlwifi power_save=0

I "solved" this by buying https://www.tp-link.com/cz/home-networking/adapter/archer-t2u-nano/. It's sad :-(

I've been experiencing this as well on two Arch laptops with Intel 8260 (rev 3a) chips - not only with ath10k (OpenWRT 19.07.x on a Unifi ac lite) but also with ipq806x (OpenWRT on a Netgear Nighthawk X4S R7800). I don't know when it's started but it's happened on and off for a number of Linux releases now. I'm unaware of my Android cell phone having any issues but I don't do a whole lot with it. Fiddling with the beacon interval didn't seem to help much.

Aha, it appears to be happening even on the stock Netgear r7800 firmware - exact same behavior. Since so many people were on OpenWRT here I figured it must be that firmware but that's been entirely disproven for me.

The same issue for ax201 on my new system76 lemur pro.
Also no problems with old laptop and intel 8265 / 8275 (rev 78) on it.

Based on https://askubuntu.com/a/1243683 it seems to be a clear cut driver regression (i. e. when they uninstall the newer backported driver the issue goes away).

Unfortunately the task (130034903) is private, but https://issuetracker.google.com/issues/172222923 has a couple of "intel.corp-partner.google.com" accounts asssigned, so hopefully Intel is getting some pressure from Google to get this fixed. Especially since it apparently also happens with Google WiFi, not just with chromebooks with intel wifi on random networks.

This issue was resolved for me a year or more ago. I don't recall which version, but one of the kernel updates fixed it. Intel 8265 wifi.

It's very much not resolved for me on the same chip (Intel Corporation Wireless 8265 / 8275 (rev 78)). I'm curious to know if you changed anything in your setup; Other than system updates everything's been the same for me.

I had to use https://aur.archlinux.org/pkgbase/linux-beacon/ to "fix it" for me

Indeed, it appears that setting the beacon timeout value to a larger value than default fixes the problem. There's a patch in the kernel bug report [1] that allows configuration of that option in the driver. I'll give beacon_timeout=256 a go with the above mentioned AUR package, which includes that patch.
