 Posted: Sun Nov 09, 2014 11:31 am Post subject: WLAN problem: "disabling HT as WMM/QoS is not supported |
 |
|
Hello,
I have a strange problem connecting to my wlan.
It works flawlessly in 11g-mode but does not work in 11n-mode at all.
The corresponding dmesg entries are:
| Code: | [ 12.421227] ath9k 0000:03:00.0 wlp3s0: disabling HT as WMM/QoS is not supported by the AP
[ 12.421230] ath9k 0000:03:00.0 wlp3s0: disabling VHT as WMM/QoS is not supported by the AP |
I have already checked these potential problems:
- Not a network quality problem and not an AP-problem (the AP is definitely configured correctly):
A Raspberry Pi with an edimax usb wifi-adapter next to the computer connects in 11n mode and no dmesg output regarding WMM/QoS is shown.
Also all other gadgets (Media players, mobile phone, Laptops, Raspberry Pis) connect at full speed.
- Not a hardware driver problem:
I tried to use the edimax usb wifi-adapter, used successfully by the Raspberry Pi in the first test. But the result was just the same:
| Code: | [ 12.610413] rtl8192cu 1-2:1.0 wlp0s18f2u2: disabling HT as WMM/QoS is not supported by the AP
[ 12.610414] rtl8192cu 1-2:1.0 wlp0s18f2u2: disabling VHT as WMM/QoS is not supported by the AP |
Also tried to deactivate hardware crypto without any success:
| Code: | | options ath9k nohwcrypt=1 |
The wlan card is capable of 11n:
From lspci:
| Code: | | 03:00.0 Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01) |
Checked in kernel config that the schedulers are included:
| Code: | CONFIG_NET_SCHED=y

Does anybody have another idea where the problem might be?

This seems to answer your question. You can't use mode 'n' with AP that doesn't support it (or has it disabled). As simple as that, mode 'n' is disabled on the other device you're connecting to. |

Thank you for your answer, but no, it's not that easy. Would be great if it was, but it isn't:
The AP is configured to do WMM/QoS and is capable of accepting n-connections.
Indeed it does so!
I have verified, that all other gadgets/computers can and do connect at n mode.
That was the first bullet point of my original post:
| Quote: | Not a network quality problem and not an AP-problem (the AP is definitely configured correctly):
A Raspberry Pi with an edimax usb wifi-adapter next to the computer connects in 11n mode and no dmesg output regarding WMM/QoS is shown.
Also all other gadgets (Media players, mobile phone, Laptops, Raspberry Pis) connect at full speed. |
If the problem is the AP, then how can a Raspberry Pi running Raspbian and using an Edimax usb-wlan-stick connect to exactly this AP in n-mode?
Furthermore, I tried to use exactly the same Edimax usb-wlan-stick originally used in the Raspberry Pi in my computer. And there it just connects in g-mode and dmesg shows the same message as when using the Atheros-PCIe-card. Plugging it back into the Raspberry: The Raspberry connects at n-mode.
So it does not seem to be a hardware or AP problem...
Any other ideas? |

Hmm.. yeah, that makes it more tricky.
Do you use WPA2? (N doesn't work with wep, not sure about wpa1) And it does not fall back to weaker stuff, right?
What about running it without encryption at all?
Oh, and what about
grep -i ath9 /usr/src/linux/.config |

Well, I use WPA2 with AES as needed for n-networks. (I think WPA1 would not work. The router is configured to just do WPA2 and AES)
So here some information about the kernel:

As you can see, the Pi connects at n-mode: "Bit Rate:150 Mb/s"
I somehow think, that there is something wrong with my kernel config but I can't find the flaw.
First I thought that the problem was the multiqueue net device scheduling, but as far as I can see, everything needed is turned on.
So I'm out of ideas...
Thanks,

That doesn't look right... your driver's limiting itself to the set of radio frequencies valid in both DE and AU. The AP may be configured to send the wrong country code there. Try overriding it with `iw reg set [correct country]` and see if that helps. Might be interesting to compare it with the RPi's dmesg output too. |

Thank you for the answeres!
Well, the dmesg output of the Raspberry is not very helpful, I think.
This is the output (I cut it where the WLAN-stick was detected):

So it does not seem to set any regdom...
However, trying your hint with "iw reg" the computer running gentoo says directly after booting:
| Code: |

So changing the reg domain does not seem to make any difference. iw reg shows "DE", which is correct and resetting it to DE does not seem to make any difference.
The dmesg output is a little bit strange though... It seems to set the reg domain to AU but "iw reg get" returns the correct "DE"-setting.
I also checked the router again but I was not able to find the setting. (The router (Linksys E3200) runs DD-WRT but the "WLAN->advanced settings" do not show a setting for the regulatory domain.
I'm not sure about that, but it might be, that the kernel "2.6.24" used by DD-WRT does not support the reg domain setting correctly...)
I also tried to omit the reg domain config I used in /etc/modprobe.d/cfg80211.conf:
Used to be:
| Code: | | options cfg80211 ieee80211_regdom=DE |
I removed file, as this line was the only entry, and rebooted.
After that the dmesg is:

On the other hand the frequency used is 2.457 GHz with 40MHz channel width.
The 2.457 GHz/40MHz setting seems to be allowed according to the dmesg output:
for "world" (unset):
[ 5.751075] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
for AU:
[ 5.821748] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm)
for DE:
[ 6.142515] cfg80211: (2400000 KHz - 2483500 KHz @ 40000 KHz), (N/A, 2000 mBm)
Or am I missing something with these frequencies?
I somehow still think the problem is with the kernel config... Does anybody know which features have to be turned on to get n-speeds?
I mean those settings apart from the wlan driver and the ieee80211 stuff. Something like the multi-queue scheduling options or any multi queue device drivers?
I can remember, some time ago, the 2.6 kernel needed an option called something like "NETDEVICE_MULTIQUEUE" (not sure about the correctness of the spelling), but that option was abandoned later.
Do I have to enable something similiar in kernel 3.14? |

Multiqueue should be used automatically if your card supports it. If it's working, `tc qdisc show` should print a "mq" line (not sure if it's always the case).
I'm out of ideas, unfortunately. You could try adding country=DE to wpa_supplicant.conf but I doubt it'll help if the other things didn't. |
