Very short range and low speeds with Intel AC 9260 chip

My laptop's wifi has a very low range and speed.
This happens most noticably with 5GHz networks, but 2.4 GHz APs are also affected by low speeds.

I tried completely reinstalling linux-firmware and linux-firmware-intel via

pacman -Rns linux-firmware{,-intel} && pacman -Syu linux-firmware{,-intel}

this did not help.

Multiple combinations of options were also tried:

# /etc/modprobe.d/iwlwifi.conf 

#options iwlwifi 11n_disable=8 
#options iwlwifi power_save=0 d0i3_disable=0 uapsd_disable=0
#options iwlwifi power_save=0 d0i3_disable=0 uapsd_disable=0 11n_disable=8
#options iwlwifi power_save=0 d0i3_disable=0 uapsd_disable=0 11n_disable=8 power_level=5 disable_11ac=0 swcrypto=1
#options iwlwifi power_save=0 d0i3_disable=0 uapsd_disable=0 11n_disable=8 disable_11ac=0
#options iwlwifi power_level=5 11n_disable=8

# ArchWiki
#options iwlwifi 11n_disable=1 swcrypto=1

Currently they are all commented out, because none of the lines improved anything.

System specs:

Re: Very short range and low speeds with Intel AC 9260 chip

Don't grep dmesg, there's a firmware crash but that doesn't explain "very low range and speed", please post your complete system journal for the boot: 

sudo journalctl -b | curl -F 'file=@-' 0x0.st

to illustrate the overall setup and situation.
if you're using NM and wpa_supplicant they'll log network quality levels, otherwise you might have to check those manually, https://wiki.archlinux.org/title/Networ … ireless#iw (though iwd and wpa_supplicant both can be queried)

If this is really a poor signal situation and not a hardware one (tried sth. like https://grml.org/ for comparism) I'd bet on power saving, see https://wiki.archlinux.org/title/Power_ … interfaces next to the parameters you've already tried.

Re: Very short range and low speeds with Intel AC 9260 chip

The journalctl is here: http://0x0.st/KM4p.txt

Signal strength

# iw dev wlan0 station dump -v
        [...]
	signal:  	-50 [-50, -53] dBm
	signal avg:	-52 dBm
	beacon signal avg:	-50 dBm
        [...]

Regarding power saving, I have now tried modprobe options:

options iwlmvm power_scheme=1
options cfg80211 cfg80211_disable_40mhz_24ghz=Y
options iwlwifi 11n_disable=8 power_level=5 power_save=0 uapsd_disable=1

which doesn't make a difference unfortunately.

"Low speed" means ~1 Mbps on 2.4GHz where other devices get ~95 Mbps.
5 GHz is not able to connect, if it is even seen, while other devices can easily connect.

Re: Very short range and low speeds with Intel AC 9260 chip

-52dBm isn't great but also not terrible and you should™ get a stable signal on that.

5 GHz is not able to connect

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855 - post the actual IO of an attempt.

There's a firmware crash early on but the NIC effortlessly connects to the AP.

Is there another OS? Parallel windows?

I have now tried modprobe options:

Why are you constraining the 11n support and limit the channel width to 20MHz?
You're nudging the system towards 802.11g performance… also uapsd_disable=1 is more aggressive power saving than the default uapsd_disable=3

For clarification: you're getting 1 mega BIT per second, not 1 mega BYTE per second?

Last check: what DNS server do you use (cat /etc/resolv.conf) and what if you change that to 1.1.1.1 (cloudflare) or 8.8.8.8 (google) - we'll deal w/ the privacy concerns etc. if this actually pans out to be the relevant factor.

Re: Very short range and low speeds with Intel AC 9260 chip

I have a dual boot of Windows 11, yes. It is used very rarely, and I can delete the partitions if that might solve my issue.

Regarding modprobe options:
I tried those that seemed to help other people, prioritizing range over speed for the time being because I wanted to make sure that there are no problems with signal strength. Limiting channel width to 20MHz was an attempt at avoiding issues with channel overlap.

For clarification: you're getting 1 mega BIT per second, not 1 mega BYTE per second?

I looked at different bench scripts this time, turns out it is indeed 1 megabyte per second. bench.sh writes "Mbps", but that seems to be incorrect.

pacman -Syu

showed an average (Total) of 857 KiB/s for the upgrade right now.

$ cat /etc/resolv.conf

nameserver 94.140.14.14
nameserver 94.140.15.15

Using 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) didn't make a difference.

Re: Very short range and low speeds with Intel AC 9260 chip

I have a dual boot of Windows 11, yes. It is used very rarely, and I can delete the partitions if that might solve my issue.

Bo, but see the 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Then leave only

options iwlmvm power_scheme=1
options iwlwifi power_save=0

and remove the other options, you have a peak of 45 Mbps what's close to the 802.11g maximum

Re: Very short range and low speeds with Intel AC 9260 chip

Booted into Windows, executed 

 powercfg /H off

and rebooted twice, followed by two reboots into linux.
The options are now as you wrote, after changing them I of course rebooted to be sure they are in effect.

Now my iperf looks worse for some reason:

And there are beacon losses and reconnects now:

Re: Very short range and low speeds with Intel AC 9260 chip

Okt 06 15:54:05 hostname wpa_supplicant[1434]: wlan0: CTRL-EVENT-DISCONNECTED bssid=78:9a:18:dd:0c:e1 reason=4 locally_generated=1

reason=4 "Disassociated due to inactivity"

after ~1m
Throughput is still all over the place but the retries have gone down massively.

Can you try to connect it to some other AP (eg. a phone hotspot)?
Edit: mostly to see whether the connection remains stable.
