just a point if one is to maintain a community build i don't think it should just for one device of the arch (ipq807x) devices.... this willl of course bring even bigger challenges ... so let's see who wins ... it feels this device will win based on affordability and performance (kind of of...)... my bet so far has been on the qnap, dl-wrx36 ... ax9000 (huum let's see if it gets fixed properly) ... however with wifi7 coming online soon all this will be defunct ... well if mtk and qualcomm get their act together ...honestly don't think i will buy a qualcomm router ever ... so betting on mtk ... no sense to invest on 6e though anymore
Well, that is a point of view.
I have always built only for devices that I own and can test. (and I have always flashed the build into my own device before uploading it).

agree it is my point of view .. and that makes sense absolutely for a community to build what you can assure yourself
Many thanks, I can understand the amount of work involved in doing it in your meticulous and well documented way.
It is much appreciated.
I compile my own builds both for R7800 and the DL-WRX36 based on your scripts and configs but I still have a lot to learn so do not feel comfortable enough yet to share those with the community.
I built OpenWRT from source yesterday. Everything works without problems except for the WLAN. It is not initialized at startup.

What could be the source of the error ?
Incorrect / non-standard bridging STP parameters on this device
I just noticed this on the DL-WRX36, which is directly connected to a switch that runs MSTP.
To reproduce, just create a brand new bridge using luci.
Here's the corresponding /etc/config/network:
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config device
option type 'bridge'
option name 'brx'
option bridge_empty '1'
config interface 'brxi'
option proto 'none'
option device 'brx'
Then to find what's wrong (installing ip-full is needed to get ip -d working):
opkg update
opkg install ip-full
ip -d show brx
Here's the output:
27: brx: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000

And here's what's wrong:
-
forward_delay 800 hello_time 100 max_age 1000
These are non-standard STP timers (1s helo, 8s forward delay, 10s max age).
IEEE802.1d recommands 2s hello, 15s forward delay and 20 s max age.
In fact a brand new bridge brough up withip link add brx type bridgehas these defaults baked in.
The timers as configured on OpenWRT assume a STP diameter of 4, whereas the default make room for a diameter of 7 ([Source]).
While I understand why these times are used (faster STP convergence of 26s vs. 50s using the standard), it should at least be documented. -
priority 32767
That's plain wrong, and is a protocol violation. STP priorities must be a multiple of 4096 (0x1000) since 802.1d-2004. [Source].
This breaks MSTP if the OpenWRT device is connected to a switch that uses MSTP.
I haven't had time to check if this affects other devices.

do you have mstpd installed and configured? i don't think there is MSTP support in linux/openwrt out of the box.
Maybe you forgot to include the firmware?
Have a look at the diffconfig from @hnyman see a few posts back: Dynalink DL-WRX36 Askey RT5010W IPQ8072A technical discussion - #1611 by hnyman
I also include my own diffconfig but I am still learing and discovering so @hnymans is the safer bet.

Oh I wish we had mstpd working (or at least some working implementation of RSTP) on Linux.
No, in my case I was describing the interaction between an OpenWRT switch running plain old STP on Dynalink DL-WRX36 wired to another switch running MSTP (in this case a Mikrotik CRS device).
The default STP priority of 32767 is plainly broken, it should be 32768 (the recommended default) or at least a multiple of 4096.
The other issue (aggressive STP configuration) is not broken, just unexpected.

The wifi firmware blob should be automatically included.
I finally got around to fixing this. I had to reset the router and re-apply configuration to get everything back to normal. I'll apply the advanced uboot params too, this time.

Uptime almost 17 days, as you can see. Running p2p with 5 torrents (linux distros), nextdns and samba4, router is main gateway doing pppoe @ home with 3 dekstop clients, 2 laptops, 5 smartphones and 3 tablets. 5Ghz radio only, 2.4Ghz is disabled because i find it useless. CPU load 0 - 20% at lowest frequency 1017Mhz. Mem available 545MB.
Thanks @ all
Yes, I am subscribed to the list so following it tightly.
We already have the 160MHz fix, but I am planning on backporting the rest as well.
I've been pretty happy with the DL-WRX36.
However, I've just noticed something very odd. Ethernet broadcast does not seem to work "sometimes".
Here's my set-up:
I have 3 DL-WRX36 functioning in dumb AP mode.
They are all bridged together for roaming but none of 802.11r, 802.11k or 802.11v are configured.
All 3 are configured on different 2.5 GHz and 5 GHz channels and have different 802.11ax colors.
I have a rather complex set up with VLANs and use new-style VLANs (bridging the untagged interface).
All three units have exactly the same configuration, they all get their address via DHCP, and the /etc/config/* files are all the same, except for hostnames and wifi channels and colors.
Now to the weird behavior:
I've noticed that while the station to AP traffic always works perfectly fine, station to station traffic sometimes didn't work. I narrowed it down to ARP traffic not flowing properly.
After investigation, I've found out that on stations connected to the 5 GHz band of one of the three units, Ethernet broadcasts were not being received. If Ethernet broadcasts are not working, then ARP doesn't work, and that explains why station-to-station traffic does not work.
To confirm the problem was Ethernet broadcast, if I add static ARP entries to the stations, then station-to-station traffic works fine.
I started investigating the problem with broadcasts. This is how I test:
The router behind the bridged/switched APs runs a ping to the wireless LAN broadcast address.
Tcpdump on all three APs see the broadcast ping arriving on the ethernet port.
Tcpdump on all three APs see the broadcast ping being emitted on both wireless LANs (2.5 GHz and 5 GHz) bridged to the ethernet port.
All the stations connected to two of the APs received the broadcast.
But on the last "problem" AP, the broadcast is only received on the stations connected to the 2.5 GHZ wireless network. Any station connected to the 5 GHz network never receives the broadcast ethernet frame.
I've also tried with multicast traffic. It does goes through.
I've tried changing channels on the problem AP, it does not help.
I'm starting to think that the problem AP may be a bad unit.
Regarding the Tx power in DL-WRX36, I was trying to find if the issue could be related to the BDF file used.
I don't know what board ID dynalink FW uses or the board ID being used in snapshot, so I tested several BDFs extracted from DL-WRX36 dynalink factory_FW wifi_partition.
From the few ones I randomly tried, bdwlan.b290 shows the correct power in luci for both radios and I can see the radio power increases accordingly.
I have no idea if .b290 is or not the correct board id (with the correct calibration), so this is only a test, but it produces the correct Tx power readings in luci and I can measured the power increase.
I also think that with the current snapshot bdf, the radio power is not the one we see in debug.
When I measure (using a phone with wifianalyser) and compare the radio power from snapshot BDF with .b290, .b290 is higher and it matches the same power values that ax3600 emits for the same settings. Note that this is empirical observation.
After one day .b290 started giving integer out of range syslog msgs.
I'll test .b292 for a few days.
The correct boad ID is documented here:
