Device: Nexx WT3020 (MT7620)
LEDE release: LEDE Reboot 17.01-SNAPSHOT r3435-65eec8b

Latest LEDE on Nexx WT3020 with MT7620 is getting syslog spammed with:
ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2

It usually occurs with high-bandwidth usage of WiFi client (Android i.e.) and results with need to reboot router (or WiFi won't even work for devices - it's seen but unable to connect).

# cat /etc/config/wireless

Also it's connected with the issue of android devices loosing connectivity/dropping wifi even 1 meter next to router:

I picked up the [[https://lists.openwrt.org/pipermail/openwrt-devel/2015-September/035776.html|patch mentioned above]] with some minor fixes into [[https://git.lede-project.org/?p=lede/dangole/staging.git;a=summary|my staging tree]]. Please build, test and report back. If it improves the situation, we may carry it in our tree for a while and then push it upstream.

psyborg55:

meanwhile i found to change gpio mode:

(*&gpiomode = readl((void *)(0xb0000060)));
if ((gpiomode & 0x100000) == 0) {
gpiomode &= (~0x100000);
writel(gpiomode, (void *)(0xb0000060));

	rt2x00_info(rt2x00dev, "Change as Normal Mode(0x%lx)\n", gpiomode);
	(*&gpiomode = readl((void *)(0xb0000060)));
	rt2x00_info(rt2x00dev, "After Change GPIO_MODE value is 0x%lx\n", gpiomode);
}</code>

comp. reg has to be 0, opposed to mtk driver where it's 0x100000 representing PA gpio mode which means rt2x00 doesn't run the PA in gpio mode. mini shows the 0x48371d value with PA enabled in DTS code and 0x58371d without it enabled.

Daniel Golle:

I tested last version of the staging trunk "mac80211: rt2x00: fix rt2800 queue management" doing the "git clone https://git.lede-project.org/lede/dangole/staging.git" and compiling it. The result it is that it hangs very fast and stop working but the tx queue 2 issue doens't appear this time in the logs but the result is the same. Need to restart device to make it working again.

It is setup as AP only and I use a just a laptop to connect to it. The connection hangs when reach 100-200 MB @ 3-5 MB/s. Before it only hangs when are more than one client connected. Now it seems that happens even with just one client.

Model | Nexx WT3020 (8M)
Versión del firmware | LEDE Reboot SNAPSHOT r5049-e53bdcb / LuCI Master (git-17.289.53761-19f30d0)
Versión del Kernel | 4.9.54

Edit #1: Seems that the hangs is caused just when WMM is activated in N mode, seems not related to the famous tx queue 2 issue. Maybe this is a new bug introduced.

Edit #2: For now, the __tx_queue __2 issue doesn't appear in N mode without the WMM (because if I enable this, it hangs very soon, as I said before, this sounds like a new bug). I will update this when I test it a bit more. For now looks good ...

Edit #3: 25 GB @ 3 MB/s without crash (N mode, No WMM, 2 clients = phone and laptop) :-)

increasing queue limit decreases throughput. use 128/64 values, if the problem does not re-appear patch might work.

sure, somebody followed standards and disabled HT rates for WMM off mode. check again you're connected at 54Mbps. so effectively G mode not N

As I said before, N mode is totally broken in the last version of Daniel Golle (LEDE Reboot SNAPSHOT r5049-e53bdcb / LuCI Master (git-17.289.53761-19f30d0))

It crash very quick at high data rates, that doesn't happens before.

Can you check it?

In my case WiFi dies, but seems to come back after some time (don't think I did anything besides logging in over LAN).

Is this issue still in trunk?

Timeless:

I also have this issue with a VGV7519 and WL-351. But I must add that the Wireless connection does not always fail when these messages appear. Sometimes it fails and sometimes I don't notice any hick up.

There was a OpenWRT issue about this aswell: https://dev.openwrt.org/ticket/12313

There are also multiple topics about this, I wont link them since I don't think it will help much.

svobodavac:

I have experienced the same problem not only on ramips/mt7620 platform (ZBT-WE2026)
but also on lantiq/xway platform (ZyXEL P-2812HNU-F1).
Both platforms use rt2x00 driver for their WLAN.

There are at least two different issues with the rt2x00 driver.

  • log messages
  • WLAN hangs

HOWTO simply reproduce WLAN hangs:

  1. Heavy load on WLAN - in my case:
    3x Samsung S4 mini connected to AP, WPA2 PSK
    AP in 802.11n mode
    1x iperf3 stream per phone against iperf3 servers on LAN, RECEIVING data TO phones

  2. Turn off WLAN on one phone (iperf3 receiver)

  3. There is approx. 50% chance that AP stops receiving packetsi mmediately from all clients after sudden client disassociation under heavy load.

  4. The only solution: rmmod kernel modules and insmod them again. (or reboot).

AP in 802.11g mode is stable.
Latest tested firmware: LEDE 17.01.2

PLEASE, PLEASE, help us with the hanging AP in N mode.
I'm able to help with testing.

Sorry it sould be:

kristrev:

Hi,

I am seeing the same issue and am trying the work-around with unloading/loading modules to get wifi back in a working state. However, I can't seem to figure out which modules to unload. Unloading seemingly relevant modules (like rt2800pci) has no effect, while the board reboots when unloading for example rt2800soc. Any hints or pointers to which module to remove?

Also, at least for me, the "Dropping frame ..."-error is harmless. However, in my case, that error message is usually (at some point) followed by the "Arrived at non-free ..." message. When the latter message arrives, wifi always hangs.

Thanks in advance for any help,
Kristian

Someone test it already?

I'm compiling it now for WT3020 (8MB) device... let's see.

24 GB at 30-50 Mbps with two devices connected (laptop and smartphone) and for now, it's working fine. No wifi dropouts. However, the logs shows the rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2.

Isn't this moment that the patch should be applied to OpenWrt then? ;-)

Have that bug too on Xiaomi MiWifi Mini
After sometime wifi stops work correctly: devices can connect, but does not receive IP address, but in logs I see, that IP is assigned. As I understand - router can receive packets from client, but can't send. In that hanged state I can wake up my PC with Wake-On-Lan magick packet from my phone over Wi-Fi.
Now I will try to compile OpenWRT 18.06.1 with patches for mac80211 from https://git.openwrt.org/?p=openwrt/staging/dangole.git and will let you know if it works

UPDATE:
No luck with applying patches from dangole to 18.06.1

@r0ck3r I have the same hardware. Which version of openwrt you recommend ?

r0ck3r:

@kofec Now I am on 18.06.1, built from source. Since I switched to it I don't had this bug, but I don't think it is related to version - this is only luck, because I don't found anything about this chip in changelog between 18.06.1 and 18.06, on which this bug has appeared twice or more for me.
Sorry for my English

@cjcr I'd like to test the firmware for you on my WT3020 (8MB) - currently having this issue with latest stable OpenWrt 18.06.1.
However Mega needs decryption key to download it.

@Ashus:

Here's the latest one based on https://github.com/sgruszka/openwrt/commits/rt2x00 that includes also some other changes. I'm using it for a week or more and is stable.

Luci, nano, usb-support, usb-storage, etc.

Got this bug again on stock 18.06.1 after 13 days of uptime
Now I applied 3 commits from https://github.com/sgruszka/openwrt/commits/rt2x00 to 18.06.1, compiled and installed. After 24h it looks stable, but I will test it for a while and will let you know

@cjcr I tested this build of yours and never seen this bug again. Tested extensively for 2 days, then a bit less for 3 more days and with another master router. The message never appeared in logs nor was it needed to reboot this OpenWRT router.

I got this error too, my device is

MediaTek MT7620A ver:2 eco:6

and firmware version is

OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152)

After I denied two wireless MACs to MAC-filter list, the wireless works for several days, and I still found the kernel log output included

ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2

Even kernel log output included

ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2,

if you modify MAC-filter list, the wireless can return to normal, I don't need restart my device.

Does anyone want to test it?

@cjcr can you tell me which patch to use and how to compile it, I have the xiaomi mini (MT7260A ver:2 eco:6) and have the same packet dropped problem in 2.4 ghz.

Update : I manage to download only the latest patch (b037ec7) using wget and main repository, after that compile it just like in the howto and after few days it seems no more packet dropped, I'll just hope it stays stable like now.

//(My device is not an MT7620, so please delete this reply if it is inapprioriate.)//

I'm using the stable release OpenWrt 18.06.2, which is very much resistant to the bug, but issue is still there (the bug is definitely not fixed). I am able to trigger the bug with high probability. How could I help fix the bug?

The issue still persists. Easily reproducible by simply installing miniupnpd, you will instantly see the log growing with frame drop messages, and by the end of the day the network will halt.

So if I understand this properly, the problem has been fixed in the snapshots builds, but still remain to be fixed in 18.06? Would be nice to know if it has been fixed in the upcoming 19.07 release https://downloads.openwrt.org/releases/19.07-SNAPSHOT/

If there is a patch that works for this would someone be able to point me in the right direction of how to apply the patch ... in layman terms please ?

I have a home automation setup so losing WIFI means losing all my home automation which as you could appreciate sucks :( . Router firmware is
