Belkin RT3200/Linksys E8450 WiFi AX discussion

umayer · February 12, 2023, 3:51pm

I was able to recover the second device which broke when I did the attended sys-upgrade.
I haven't had changed anything on that one. @rincewind correctly spotted the root cause of my problem: kmod-mt7915-firmware was missing
After opkg install kmod-mt7915-firmware this device is back to normal operation.

Question remains: could a hick-up in attended sysupgrade cause packets to be dropped?
Because the older image I was running also required that package.
And e.g. kmod-mt7622-firmware was still installed.

This is not a hick-up of attended sysupgrade, but rather a change in OpenWrt's development tree: previously all firmware needed was shipped in the kmod-mt7915e package. Only recently the firmware has been split-off into a package of its own (kmod-mt7915-firmware). Obviously asu can't know about that (there is a mechanism to configure package replacements and such, but in it is not expressive enough to cover this situation, unfortunately)

I have had the situation of mobile devices loosing connectivity again, similar to what @Brain2000 described:
Four people visited, i.e. slightly more mobile devices than usual.

router:  192.168.1.1
AP apw:  192.168.1.3
AP apa:  192.168.1.5
AP aps:  192.168.1.7
Laptop:  192.168.1.174 wired to apa
desktop: 192.168.1.35 wired to apa
printer: 192.168.1.20

mobile:  192.168.1.108 wifi to apa

works:
ping from mobile to all destinations but router
ping from apa and machines wired to apa to mobile

no connection:
ping from router to mobile:
ping from mobile to router

in between:
ping from aps/apw to mobile

root@aps:~# ping 192.168.1.108

round-trip min/avg/max = 344.466/442.008/539.550 ms

Note that the first two pings worked, but then it fails to continue and 28 lost packages follow.

For anyone following my travails with the 2.4Ghz radio not working on a Belkin RT3200, I found the solution and updated the most relevant post in this thread with everything.

Should there perhaps be advice against, or a more in-your-face warning about, the schedutil CPU scaling governor setting on MT7622 devices, how it's considered "out-of-spec" and may not work? Maybe it works for some lucky souls, but not in my case.

I spent an embarrassing amount of time and effort debugging this when it was my fault for putting the schedutil CPU scaling governor setting in from the very beginning, assuming it was well-vetted and safe, since it's even suggested in the official device wiki.

Anteus · February 12, 2023, 8:54pm

Snapshot runs ondemand as default for a while. I've updated the wiki example to ondemand.

git #9a07895 is long before 895f38ca1efeb46f0cd3029c732e6156d4589eb0, which is the one I tried to upgrade from.
I do actually recall that I did not need to install kmod-mt7915e but only the two FW packages.
That is why I mentioned that the FW for 7622 was still installed.

I did open an asu issue before the issue seems to have resolved and I initiated my then failing upgrade:

Don't get me wrong. I really appreciate asu. before that I compiled my own images, because otherwise it was not possible to keep the configuration.
I'm a little concerned that there might be a race condition which on rare occasions causes packets to not be (properly?) included.

I still have the itb file in question. Is there a way to inspect it?

umayer · February 13, 2023, 8:29am

just for completeness:
wifi only brought the mobile up for a short period.
/etc/init.d/bridger restart had the same effect.

But only a reboot on apa fixed it for good.

anon11662642 · February 13, 2023, 4:38pm

When I use ondemand the same thing happens to me only in one of the two routers that I have and I solved it by changing the minimum frequency to 600000 kHz up from the default 437500 kHz.

~# cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies
437500 600000 812500 1025000 1137500 1262500 1350000

Testing:

437500 kHz = Using the default minimum frequency does not boot after reboot.
600000 kHz = Boot without problems after reboot.

Fix:

echo 600000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq
echo ondemand > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

This is why this problem happens and why it is solved by changing the minimum frequency:

Minimum frequency to 437500 kHz = 1.0V.

github.com

torvalds/linux/blob/master/arch/arm64/boot/dts/mediatek/mt7622.dtsi#L31-L33


      
          		opp-437500000 {
          			opp-hz = /bits/ 64 <437500000>;
          			opp-microvolt = <1000000>;

Minimum frequency to 600000 kHz = 1.05V.

I created a snapshot from yesterday master branch and 160mhz is gone from luci. I only have 80mhz. Anybody expericed the same? The country is set to CA.

Just found this : Belkin RT3200/Linksys E8450 WiFi AX discussion - #3381 by namidairo

loyukfai · February 15, 2023, 6:07pm

Thansk! So the command shouldn't be needed after 23.xx release?

Cheers.

FanOfOpenWRT · February 16, 2023, 3:39pm

There is a discussion on Github about the removal of 160Mhz on the RT3200.

Another, newer Github comment here.

It was removed (in development/snapshot), on purpose, but some are saying it was not necessary to remove.

FanOfOpenWRT · February 16, 2023, 10:32pm

I asked ChatGPT a question that I had after reading this comment on Github.

Is this accurate?? When are we going to test & try this on the RT3200?

(transcription of image text: "Yes, the MediaTek MT7915E chipset used in the Belkin RT3200 router supports the 6GHz frequency band, which includes the new Wi-Fi 6E standard.")

loopy321 · February 16, 2023, 11:13pm

No 6GHz radio: https://fccid.io/K7S-03572

FanOfOpenWRT · February 16, 2023, 11:30pm

This must be why it's labeled/marketed as "dual band" (2.4GHz & 5GHz) and not "tri-band" (adding 6GHz)?

Maybe try flashing 22.03.3? There may still be value in diagnosing the issue, but if it's fixed in 22.03.3, less so.

campbelltech · February 22, 2023, 8:21pm

I believe what you're looking at is the version of initramfs recovery (22.03.1). The router (22.03.3) had just crashed so I connected to recovery with ssh to pull the logs. I've tried 22.03.3 and the latest snapshot but I have crashes with both.

eginnc · February 22, 2023, 11:16pm

That's unfortunate. So much for the simple fix. Sorry I can't help further.

campbelltech · February 22, 2023, 11:44pm

No worries. Hopefully someone will come along.
