Ipq806x NSS build (Netgear R7800 / TP-Link C2600 / Linksys EA8500)

Yep, all of those additional settings are optional.

Some people run the performance governor so you can run this if you want:

The speed should be the same. I haven’t seen a difference between aggressive on demand vs performance for typical use.

i have not tested your latest firmware yet and am currently still on hnyman's build. due to my apartment i am forced to use my desktop pc over wifi through multiple walls at the edge of 5 ghz range.
my asus wlan card supports 160mhz and i manage 220mbit (iperf and speedtest) due to the still poor reception strength. the main advantage with 160mhz is that the stability (no drops) is much better than with 80 mhz. but i confirm with apple devices i struggle from openwrt beginning. if this is due to the 160mhz i need to test

Hi @ACwifidude
i am using your OpenWrt 21.02 (Stable) + NSS Hardware Offloading (20210620 factory > 20210905 sysupgrade > 20211010 sysupgrade) build on my R7800.

I just did a Ping test on https://ipv6-test.com/speedtest/ and noticed that I get about 4% packet loss (reproducible ) over IPv6. Take a look at the screenshot below.

And this is what I get in the logs.

Tue Oct 26 07:22:33 2021 user.notice firewall: Reloading firewall due to ifupdate of wan (eth0.2)
Tue Oct 26 08:03:43 2021 daemon.notice netifd: wan6 (16925): cat: write error: Broken pipe

Tue Oct 26 08:15:36 2021 daemon.notice netifd: wan6 (16925): cat: write error: Broken pipe

I have no clue if the logs and the packet loss are somehow related or not. Also it might be totally up to my ISP (Vodafone Germany, NRW). I am using their new Vodafone Station (WiFi 6, Technicolor CGA6444VF) in BridgeMode (Modem Only Mode). It is a native Dual Stack (no DS-Lite) configuration.

To investigate further I did some iperf3 tests from my desktop PC and from the router:

There is quite some packet loss with IPv6.

During those tests I got some more logs:

Tue Oct 26 09:14:23 2021 daemon.notice netifd: wan6 (16925): cat: write error: Broken pipe

Tue Oct 26 09:19:28 2021 daemon.notice netifd: wan6 (16925): cat: write error: Broken pipe

One more thing to note: The IPv6 test from my Desktop PC looked different to the ones from my R7800.

What are all the other users here thinking?

Why do I get packet loss over IPv6 (only)?

my ISP Vodafone Germany (NRW)
OpenWRT in general
this specific ROM by ACwifidue
my testing procedure
something else

I don't want to blame anyhone here. I am just curious.

Now I tried to do some more iperf3 tests from my R7800 but I constantly get
iperf3: error - unable to write to stream socket: Permission denied
after some seconds (e.g. after 21s, 27s, 111s in the test).

and even more logs

no troubles testing IPv4 though

Is this somehow related to bittorrent crashes over UDP?

@xeonpj are those UDP torrents IPv4 or IPv6?

IPv6 TCP success

Keep in mind that I never used iperf ever before.

ACwifidude · October 26, 2021, 1:43pm

The R7800 should be between two clients like it would be in real life. While you can run iperf client from the R7800 - I wouldn’t, the R7800 is heavily underpowered to both route packets and originate/receive packets. You’ll get unsual results when you are making the router be both a client and router.

Run the tests again with two clients on your network with the R7800 in between. That will help isolate is the R7800 routing well vs. what the ISP is doing.

ACwifidude · October 31, 2021, 2:16am

Today’s 21.02 build is one commit ahead of the new 21.02.1 release. Working well on the R7800s.

aamadorj · October 31, 2021, 9:45pm

Newest build (ath10k-ct version) is also working fine on my R7500v2. Thanks a lot, @ACwifidude.

SiXX · November 1, 2021, 3:41pm

Long time lurker, first time poster. Just wanted to say THANK YOU for these builds! I maintain both an R7800 and a Zyxel NBG6817... I've been running your CT builds for around six months now and the performance is incredible. I run a very vanilla OpenWRT (really only utilizing BCP38 and Stubby which I add in), and the stability is fantastic on both routers. Since the R7800 is now discontinued, the Zyxel has proven to be every bit as good for my needs... just runs around 20ish degrees warmer.

Again - Thank you!! @ACwifidude

nashford · November 1, 2021, 8:14pm

Hey @ACwifidude long time no chat - hope all is well. Reflashed the most fecent NSS stable you had, whats the status of 160 MHZ 5G for R7800 ? i dont seem to be able to get 160 to enable. is there some trick ? Thanks again for the updates etc.

ACwifidude · November 2, 2021, 2:39am

Take a look at your regulatory settings and first see what the acceptable range is.

        (5150 - 5250 @ 80), (N/A, 23), (N/A), AUTO-BW
        (5250 - 5350 @ 80), (N/A, 23), (0 ms), DFS, AUTO-BW

        (57240 - 71000 @ 2160), (N/A, 40), (N/A)

In the US to get 160mhz - set the channel to 100, wait a couple minutes for the router to make sure there is no RFS (radar interference) and you should be good to go.

nashford · November 3, 2021, 11:05pm

Am in the US - had that set - it never came up. am not on CT driver, on the old. is there an issue there ?

ACwifidude · November 4, 2021, 1:43am

Both drivers should work now (but not always with every client).

Two reasons most likely reasons it won’t work is either -

the drivers don’t like the 160mhz client or
Your router is picking up radar and is not allowing 160mhz.

Try the -ct drivers and see if you see a difference.

dtaht · November 4, 2021, 3:32pm

is there anyone out there that can run some tests on the htb+fq_codel offload in this chip?

ACwifidude · November 5, 2021, 1:46am

NSS fq codel is quite potent - getting near line rate with latency similar to fq codel. Anything in particular you want to see on the test?

dtaht · November 5, 2021, 1:52am

Two tests: line rate with a packet cap (if possible), fq_codel on and off.

With a tbf 200mbit. I asked kong over here to take a look, as I lack hardware (I actually do have this hardware in my storage unit), some more details about the test here: CeroWrt II - would anyone care? - #36 by KONG

I'm happy to hear you think it's good, but I've been worrying about the codel implementation in the 500-900mbit range. I think they implemented the wrong drop scheduler.

kesagatame · November 5, 2021, 6:05am

I suppose this ath10k fix didn't make it into the 21.x build from October 30th?

Fiouz · November 5, 2021, 7:21am

Correct, but that fix isn't needed for the 21.x branch in the first place, as the faulty mac80211 implementation was only recently backported to the master branch (21.x was branched off many months ago).

The bug on OpenWrt master was discussed at

ath10k: add target IRAM recovery feature support

committed 06:07PM - 23 Nov 20 UTC

+88 -0

This target IRAM recovery feature support is to copy target IRAM contents availa…ble at ATH10K_MEM_REGION_TYPE_REG to host memory for back up after firmware loaded. Target IRAM contents are copied to wmi memory chunks allocated for the WMI_IRAM_RECOVERY_HOST_MEM_REQ_ID and provide the wmi chunks address to the firmware through wmi init command. If firmware detects andy IRAM corruption through periodic checksum validation, It will download the IRAM contents back from the provided wmi memory chunks address using hif_memcpy. This IRAM recovery feature prevent target assert in case of unexpected target IRAM corruptions. This patch also introduce a new feature flag 'iram-recovery' for backward compatibility.

ath10k: fix module load regression with iram-recovery feature

committed 01:05PM - 25 Oct 21 UTC

+24 -5

Commit 9af7c32ceca8 ("ath10k: add target IRAM recovery feature support") introdu…ced a new firmware feature flag ATH10K_FW_FEATURE_IRAM_RECOVERY. But this caused ath10k_pci module load to fail if ATH10K_FW_CRASH_DUMP_RAM_DATA bit was not enabled in the ath10k coredump_mask module parameter: [ 2209.328190] ath10k_pci 0000:02:00.0: qca9984/qca9994 hw1.0 target 0x01000000 chip_id 0x00000000 sub 168c:cafe [ 2209.434414] ath10k_pci 0000:02:00.0: kconfig debug 1 debugfs 1 tracing 1 dfs 1 testmode 1 [ 2209.547191] ath10k_pci 0000:02:00.0: firmware ver 10.4-3.9.0.2-00099 api 5 features no-p2p,mfp,peer-flow-ctrl,btcoex-param,allows-mesh-bcast,no-ps,peer-fixed-rate,iram-recovery crc32 cbade90a [ 2210.896485] ath10k_pci 0000:02:00.0: board_file api 1 bmi_id 0:1 crc32 a040efc2 [ 2213.603339] ath10k_pci 0000:02:00.0: failed to copy target iram contents: -12 [ 2213.839027] ath10k_pci 0000:02:00.0: could not init core (-12) [ 2213.933910] ath10k_pci 0000:02:00.0: could not probe fw (-12) And by default coredump_mask does not have ATH10K_FW_CRASH_DUMP_RAM_DATA enabled so anyone using a firmware with iram-recovery feature would fail. To my knowledge only QCA9984 firmwares starting from release 10.4-3.9.0.2-00099 enabled the feature. The reason for regression was that ath10k_core_copy_target_iram() used ath10k_coredump_get_mem_layout() to get the memory layout, but when ATH10K_FW_CRASH_DUMP_RAM_DATA was disabled it would get just NULL and bail out with an error. While looking at all this I noticed another bug: if CONFIG_DEV_COREDUMP is disabled but the firmware has iram-recovery enabled the module load fails with similar error messages. I fixed that by returning 0 from ath10k_core_copy_target_iram() when _ath10k_coredump_get_mem_layout() returns NULL.

Edit: I'm referring to the OpenWrt master and 21.x branches, not the one from ACwifidude, but I guess he would not have performed the mac80211 backport himself as I'd guess it's not strictly specific to NSS.

that I turn on the pc that I have connected by cable, and it takes about 30 seconds for the internet to be available, is a negative thing. Does anyone else happen to him? what cause is possible? I have proven the problem that it is from the r7800. Thank you!
