How to use Wifi, as client, from BPI-R2 to shared internet to Ethernet interfaces?

clement · June 16, 2023, 11:30am

Thank you for your answers! It is very unfortunate that I cannot use the MT6625. I got this board because of the integrated wifi chip.

I have couple of wifi card at home, they were meant for other devices, but I’ll try with them, otherwise I’ll get the one you recommend.

frank-w · June 16, 2023, 12:26pm

I have upported the messy driver for mt6625l long time but changes in linux 6.0 were too much to change it.

But you can my 5.15 lts kernel which has support for it some years as it is a LTS

Sry

clement · June 16, 2023, 1:34pm

I’d like to try that Where shall I start? Do you have an image somewhere? or do I need to build my own (if so, do you have a doc)? Thanks!

frank-w · June 16, 2023, 2:47pm

I have some images (debian/ubuntu) posted here in forum but afaik not with 5.15,but you can replace kernel with precompiled from my github-repo (releases page)

clement · June 17, 2023, 8:43pm

Here what I did.

From https://drive.google.com/drive/folders/1oP7jy1KrrIOifvImo2nQ59wx3_9hHkgk I got the image bpi-r2-buster_5.4.58.img. I copied it on the SD Card

sudo dd status=progress if=bpi-r2-buster_5.4.58.img of=/dev/sdb

Then I cloned this repo

git clone https://github.com/frank-w/BPI-Router-Linux

And follow the instructions

sudo apt install gcc-arm-linux-gnueabihf libc6-armhf-cross u-boot-tools bc make ccache gcc libc6-dev libncurses5-dev libssl-dev bison flex

cd BPI-Router-Linux
./build.sh importconfig
./build.sh

Then I extracted the archive

cd
gunzip SD/bpi-r2_5.15.103-main.tar.gz
tar -xf SD/bpi-r2_5.15.103-main.tar

I update the boot partition

mkdir boot
sudo mount /dev/sdb1 boot
sudo rm -r boot/bananapi/bpi-r2/linux
sudo cp -r BPI-BOOT/bananapi/bpi-r2/linux boot/bananapi/bpi-r2
sudo umount boot

Then I add the files for the root partition

mkdir root
sudo mount /dev/sdb2 root
sudo rsync -a BPI-ROOT/ root
sudo umount root

After I boot, I can see the kernel is right one

root@bpi-r2:~# uname -r
5.15.103-bpi-r2-main
root@bpi-r2:~#

But I cannot see the wifi card (I’d expect something like wlan)

But it seems to have an issue and ip link confirms that no new interface appears.

frank-w · June 17, 2023, 9:00pm

there are 2 commands needed to make it work…look in the wifi.sh i have on my lts-main-branches (5.4-main,5.10-main,5.15-main).

have you loaded the wifi-modules?

clement · June 17, 2023, 9:15pm

I’m sorry, I probably miss something obvious, but I cannot find the wifi.sh in the repo

Ok, this script is not present in 5.15 branch, that’s why I could find it. Thanks.

There is no file regulatory.db on the system. Is such file expected?

frank-w · June 18, 2023, 5:49am

Have you started the stp command and is it running?

Look in wifi.sh for more

Regulatory.db is not needed for wifi driver. It is maybe needed for 5g if there is no other way to load regulatory (afair crda works around this and uses builtin regdb from linux kernel).

I use 5.15 (afaik .80) on my router with the internal wifi and debian.

Now that I found your release page, I will try with one from your CI

Steps I followed

Clean old folders

rm -rf BPI-BOOT
rm -rf BPI-ROOT

Get the build

wget https://github.com/frank-w/BPI-Router-Linux/releases/download/CI-BUILD-5.15-main-5.15.103-2023-03-18_2023/bpi-r2_5.15.103-main.tar.gz
gunzip bpi-r2_5.15.103-main.tar.gz
tar -xf bpi-r2_5.15.103-main.tar

Boot partition

mkdir -p boot
sudo mount /dev/sdb1 boot
sudo rm -r boot/bananapi/bpi-r2/linux
sudo cp -r BPI-BOOT/bananapi/bpi-r2/linux boot/bananapi/bpi-r2
sudo umount boot

Root partition

mkdir -p root
sudo mount /dev/sdb2 root
sudo rsync -a BPI-ROOT/ root
sudo umount root

Still no luck

I don’t know what am I missing

clement · June 18, 2023, 9:42am

Ok, I have a clue on which steps I’m missing. I tried the kernel 5.10 and I managed to get the AP mode. From wifi.sh, I understood that I need to write something the device wmtWifi. So 0 is to reset the device, A for AP mode. What am I suppose to write to get the wifi working as client? I stupidly write 1 and I think I’m into something

I never used client mode with the internal wifi,so it is possible that driver is broken here. I renamed the original wlan0 (was hardcoded in driver) to mt6625_0 to avoid clashes with pcie wifi-cards because for ap-mode this is only a control interface as step between to get ap0 interface…maybe for client-mode it does more.

Virnik · December 16, 2024, 5:05pm

Nah, client mode works fine. But he faces the same regdomain issue I described in the other thread.

Note this:

[  135.770683] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
[  135.779383] cfg80211: failed to load regulatory.db

That is why the interface stays down. The kernel will refuse to use the interface in both AP and client mode in case it thinks there is DFS rule to enforce, regardless whether scan or EEPROM read fails.

As a result, hostapd will fail to start in master/AP mode and interface will stay down in client mode.

I made a patch for this, fixing this issue for both master and client mode.

frank-w · December 16, 2024, 6:02pm

internal wifi only can do 2.4GHz and imho this does not need regdomain (only 5GHz and up).

Tested in AP mode and in client mode. Internal wireless on BananaPi R2 is hybrid, two-interface MAC wireless device. While ath9k loads first and registers wlan0 under its phy0 (which has two layers, one for 2.4GHz, and another for 5GHz), BPi-R2 internal wireless spawns two physical interfaces, both using either wlan0 (if alone with no other wireless card inserted), or as mt6625_0 if wlan0 is already taken. Either way, phy1 and phy2 do represent separate MACs, one for 2.4GHz, and another for 5GHz. The driver switches over to either one depending on configuration and channel requested.

frank-w · December 26, 2024, 9:20am

ok, then i remembered wrong…then problem was ac mode missing, only a…but wonder about frequencies go up to 6GHz.

the mt6625_0 is from my changes as the driver created wlanX depending of existing interfaces, but ap-mode always targeted wlan0 and did not startup when another wifi-card was recognized earlier.

not sure why these 2 interfaces are created, but wlan0 should not be created, at least for ap-mode…maybe it is created for client-mode i have not tested in latest versions.

but if you are able to port the driver to 6.1/6.6 maybe some users are happy to keep r2 with internal wifi running…i replaced my r2 with r3 some months ago to have latest lts kernel running.

Virnik · December 26, 2024, 11:28am

wlan0 in my case is created by ath9k driver, as I do use Atheros AR958x card for peer link.

Your changes works fine. Haven’t tested AC on internal card, as this will serve guest users from the street, so 802.11n will do fine.

As for 6GHz, it is a matter of modulator in the card and the driver. As I unlocked regdomain limits, all channels the card reports to support are visible. As I am no idiot, I made sure to disable those I won’t ever need. While I do not use DFS and disable it on any router I own, I am picky on frequencies I do use, and occupy. I know local meteo radar frequencies and their directions, as well as military frequencies from nearby military base, so I stay clear from them. Plus, I use tge same channels with the same width and same directions for past 25 years.

But it is ok for within-the-wall testing I was doing.
