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

Banana Pi BPI-R4/BPI-R3 Mini/BPI-R3/BPI-R64/BPI-R2
1

Hello,

I have a BPI-R2. I would like to:

  1. connect the BPI-R2 to my local network using wifi (so, as client, not acting like AP).
  2. connect my computers to Ethernet interfaces.
  3. forward internet from the wifi interface to the Ethernet.
  4. have all devices in the same network than my local network (192.168.1.0/24)

I tried different images and I struggle with the first step. The only image I found with working wifi as client is

But I couldn’t manage to share my internet connection.

I saw a similar topic from 5years ago, but restricted to OpenWRT and it was a dead end

I hope since them, things got better.

My first question is, is it possible? If so, what’s the best image for this purpose?

Thank you!

Hi Clement, welcome to the forum!

If you mean using the BPI-R2’s own built-in WiFi, then no, I don’t think this is possible. The R2’s wifi uses an old MediaTek WiFi chipset (MT6625) that was a dead end and never got mainline Linux support. There are a few patched kernels and images out there that have support for it, but these haven’t been updated in years and I would not use them. I fought with the source code to try and get this driver to work in modern OpenWrt builds and failed.

In my view, the only real option is to get a mPCIe card for the R2 and use it that way. This is what I do. I have an AsiaRF AW7915-NP1 card in mine, and this works very very well with all modern versions of OpenWrt

If you have or get a card like this, then yes, what you want is very possible. One of two ways:

  1. The best way is if you have another OpenWrt router as the main router broadcasting WiFi. Then you can use WDS mode on the main router (access point) and the second router (wifi/ethernet bridge) and it will work seeamlessly.
  2. If your main router isn’t also OpenWrt then you need to set up the second router as a client bridge. Instructions are here: https://openwrt.org/docs/guide-user/network/wifi/relay_configuration

My R2 with the 7915 card in it is working as a client bridge right now, and it works great.

3

You could even use a cheap mt7612en…

If you must have the same subnet, then you do not use maquerade / nat.

This means that you need to put the wifi and lan ports on the very same bridge. Then also dhcp negotiation goes over the wifi connection to the main router. Then your ethernet clients are in the same subnet as the wifi clients of the router.

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.

5

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

I’d like to try that :slight_smile: 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!

7

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)

8

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.

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?

11

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

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

It seems there is still an issue.

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

root@bpi-r2:~# find / -name "regulatory*"

but it seems not fully working

root@bpi-r2:~#
15

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

Since you mention the .80, I try this one.

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-5.15.80-2022-11-28_1508/bpi-r2_5.15.80-main.tar.gz
gunzip bpi-r2_5.15.80-main.tar.gz
tar -xf bpi-r2_5.15.80-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

It still doesn’t work.

I don’t know what am I missing :frowning:

17

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 :slight_smile:

auto mt6625_0
iface mt6625_0 inet static
   address 192.168.1.19
   netmask 255.255.255.0
   gateway 192.168.1.1

   wpa-key-mgmt WPA-PSK

But still doesn’t work

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.
