Belkin RT3200/MT7915E: WED + Intel AX200 = iwlwifi 0000:03:00.0: Unhandled alg: 0x703 #747

Open RSpliet opened 1 year ago

RSpliet commented 1 year ago

When enabling WED on my Belkin RT3200, the Intel AX200 occasionally shows the following message: iwlwifi 0000:03:00.0: Unhandled alg: 0x703 I've monitored the same machine for a week with WED disabled and this issue does not appear. I suspect that occasional garbage packages reach the client. On older kernels I've seen this issue lead to firmware hangs/resets on the client side, but the log I'm currently looking at does not mention any such firmware resets. It may have gotten more robust with updates on either router- or client side.

Router:

Client:

Note that this client-server combination also experiences #724 , regardless of whether WED is enabled or disabled.

Does this patch https://pastebin.mozilla.org/mWZ5tLU6/raw fix it?

RSpliet commented 1 year ago

Thanks for this patch. Unfortunately I don't have a local kernel-build set-up for OpenWRT, I tend to always make use of the imagebuilder which pulls in a precompiled kernel. Sadly I don't have a lot of spare time to dive into creating one. Is there any other way I can test this change (e.g. a precompiled kernel I can obtain from elsewhere)?

RSpliet commented 1 year ago

@ryderlee1110 Is the patch you proposed (which unfortunately already disappeared) equal or similar to b0721b96927b986f3682428e941ed4fb863d0737 ? If so: I just installed OpenWrt SNAPSHOT r22190-12a3c863d2 ("bmips: loader-lzma: drop unused RAMSIZE parameter"), which includes said commit. I re-enabled WED and I'll monitor my client machine for the next few days to confirm whether there's improvement with this issue. With the caveat that I also re-enabled 160MHz now that it's available again.

@ryderlee1110 Following up: I've had to downgrade back to the previous snapshot I had backed up because downspeed on 2.4GHz with the latest snapshot was abysmal. Didn't exceed 6Mbps either with or without WED. I'll open a separate bug report for that.

2.4 GHz throughput issue should be fixed in latest master

RSpliet commented 1 year ago

@nbd168 Thanks, I'll give it a go again tomorrow when the snapshot builder had a go. And generally thanks (all!) for your hard work on the MT7622 platform; despite the occasional niggles this router on OpenWRT feels like a massive upgrade from ISP-issued routers and stock firmwares!

Alas, the issue hasn't gone yet. I've started spotting these in my logs: [94357.662888] iwlwifi 0000:03:00.0: Unhandled alg: 0x707 (No longer 703, but I'm not sure this signifies much!)

And also the ax200's firmware didn't like what's going on:

So back to turning WED off I guess.
