BPI-R2 integrated WiFi trouble

furumc · November 3, 2020, 8:45am

Echo 0 has been done before in my wifi script ( based on yours ). Now I’ve downloaded your script, and run it, but no success! I see ap0 is there, has ip address, but not visible as wifi.

Hostapd doesn’t throw anything :

Maybe I should test it with another OS, but I’m afraid there is a harware issue!

frank-w · November 3, 2020, 9:07am

I guess it’s no hw issue…more the buggy driver

This looks strange…need to look where it is located…have you tried simple reboot? Where do you call the initialisation script? Which OS do you use? Stretch and earlier may have problems with kernels 5.4+ (i saw some warning about unsupported modes in stretch+5.4,but in my case they did not break).

Sometimes reset failes,but after clean boot (maybe try powercycle) it should came “up”.

furumc · November 3, 2020, 11:33am

Simple reboot was tried more times. I call my initialisation script with rc.local. OS is debian buster, kernel is 5.4.72.

5.4 kernel is in use since april, then was ordered an MT7612e card and helped me set it up. The problem is recognised maybe a month ago, only from yesterday I’m not able to use it.

frank-w · November 3, 2020, 11:36am

mhm, so basicly same setup as my current non-migrated version (up since 19days 18h with kernel 5.4.66). so here output of my lsmod:

maybe it gives you a clue if and which module may break internal wifi

Which kernel do you use exactly? Maybe there is any breaking commit after 5.4.66 i’m using

furumc · November 23, 2020, 9:58am

Sorry for the late answer! Kernel is 5.4.72 ( added nft_queue ) . I see following difference, in my kernel modules this one has bigger size :

mt76x2_common 28672 1 mt76x2e

You are using iptables, therefore more modules related to it, on my side nftables works.

Should I try re-copy the driver?

frank-w · November 23, 2020, 11:19am

Have you tried without nft_queue? Maybe this has same breaking effect as the known CONFIG_NET_SCH_FQ_CODEL / CONFIG_NET_SCH_FQ

furumc · November 24, 2020, 11:23am

I tried it now, without success! Same output, as before!

What does it mean:

Other idea?

frank-w · November 24, 2020, 11:51am

Without this option you have same state as my repo? Strange because the uploaded version works on my buster-image…have you installed wpa_supplicant or any other related package i have not (hostapd,dnsmasq,lxc with net,openvpn,iptables)?

furumc · November 24, 2020, 12:57pm

I’ve copied all files from here to under /lib/firmwares :

No wpa-cupplicant, but hostapd, dnsmasq, lxc with net, nftables. It’s strange because it worked for a while.

Now I’m testing 5ghz on internal wifi, it’s stable. But with 2,4ghz comes trouble. It disturbs me a bit, because this was set only for some IoT devices. On the other hand, I’m not really satisfied with the range of mt7612 2,4ghz. What about BPI-MT7615? Better range?

frank-w · November 24, 2020, 2:11pm

have not done AP-test on mt7615 yet due to missing time

Could you try without nftables loaded?

furumc · November 24, 2020, 6:45pm

Which one do you have?

Or this one :

furumc · November 24, 2020, 6:56pm

I can’t, because my firewall is fully nftables! But I have another idea!

About 2 months ago I migrated boot and root partitions from sd to emmc and had problem with lxcfs and fuse fs. My system is running from sd, hadn’t enough time to handle this. I remember it run whitout issue. Tomorrow I will test it, the 2 months previously system is untouchable.

frank-w · November 24, 2020, 6:59pm

this one: 802.11ac 4x4 standard size mini pcie card is launched

but i thought you have problem with internal wifi and 2g4 mode

furumc · November 25, 2020, 11:33am

Frank! I wasn’t clear enough, sorry! I just wanted to say that I have a copie from my system!

Now I tested, and my suspicion comes true!

If you can remember, you generated for me 2 deb packages :

[frank-w] released this 24 days ago - defconfig: add NETFILTER_XT_TARGET_NFQUEUE

and one day later

[frank-w] released this 23 days ago - defconfig: r2: add CONFIG_NFT_QUEUE

I think the issue exists with NETFILTER_XT_TARGET_NFQUEUE module.

Why do I say it? Because after eliminated CONFIG_NFT_QUEUE module, problem still existed.

frank-w · November 25, 2020, 1:15pm

Have you tried without NETFILTER_XT_TARGET_NFQUEUE?

furumc · November 26, 2020, 2:19pm

Yes, I’ve compiled a kernel whitout NETFILTER_XT_TARGET_NFQUEUE!

root@bpi-r2:/home/kernel$ cat running.config | grep -i queue
CONFIG_POSIX_MQUEUE=y
CONFIG_POSIX_MQUEUE_SYSCTL=y
CONFIG_NETFILTER_NETLINK_QUEUE=m
CONFIG_NFT_QUEUE=m
# CONFIG_NETFILTER_XT_TARGET_NFQUEUE is not set
# Queueing/Scheduling
root@bpi-r2:/home/kernel$ uname -a
Linux bpi-r2 5.4.80-bpi-r2-main #2 SMP Thu Nov 26 14:30:11 CET 2020 armv7l GNU/Linux

I’m able to run internal wifi finally.

Two question : I"ve followod your instructions in order to recompile kernel on github. Deb package is ready and installed. Why don’t see corresponding config file under /boot? Anyway, I could check it.

How did you get mentioned MTK7615 pcie card? On the page you linked is to expensive! Rather I should order it from aliexpress and all the same from which vendor(Unielec, Sinovoip)?

the new deb-package is created from modified linux-script and does not contain the uEnv.txt modifications, you have to do it your own. but it contains the source-Package if you want to compile additional modules on BPI-R2 itself

root@bpi-r2:/home/kernel$ cat running.config | grep -i queue

you know ikconfig?

modprobe configs
zcat /proc/config.gz | grep '...'

you do not need to copy the .config to target-system but good to hear, your problem is solved…i guess i should drop this module, right?

Absolutely, please drop this module!

I did it so, modprobe configs, didn’t know, just googled!

What about the card? On the page you’ve linked is to expensive! Or should I order it from aliexpress and all the same from which vendor(Unielec, Sinovoip)?
