I wish i had anyone who knows what the driver does and do a rewrite to a much smaller codebase. But there is nobody…and no documentation. I can only port by compile errors…
Dear @frank-w, @DeadMeat I remove sch_fq_codel module and it works as it should! 
for the same reason, there was no outgoing traffic (I thought the problem was in iptables rules 
)

But fq_codel is not an extra module, so now you need to configure it correctly…
Without ap0 (ethernet only)? Then it will be interesting if same problem is still in 5.9-rc4
What do you mean with configure correctly? Should do fq_codel it for you?
I didn’t test LAN, Ap0 only. banana Pi has Internet access via WAN.
To work with the module sch_fq_codel 
You have dropped it and it works right? Then it is problem with it. We need to know if it only affects ap0 (so it is wifi-driver incompatibility/bug) or network generic (then problem is in sch_fq_*)

Hi! The sch_fq_codel module only causes problems with WiFi. The wired connection works fine.

valid_lft forever preferred_lft foreverThanks for testing,than it seems to be a bug in wifi-driver,but the values are huge for eth0/lan1/br0 too…so this numbers do not indicating the error. I guess there is any callback function called that breaks functionality,but have no clue where to search
i tried starting ap-mode in 5.10, but it hangs (can login via ssh) and does not create the ap0 interface

i unloaded mt7615-module and it works…seems like any conflict 
maybe because my mt7615 is named wlan0 and mt6625l tries also creating an wlan0 device (additional to the ap0)
correct, i rebooted, enabled dbdc on mt7615 (for other test) and renamed both interfaces
ip link set wlan0 name wlan_2g
ip link set wlan1 name wlan_5g
and then started wifi.sh for internal ap0, works and ip a show this:

so it looks like driver tries to create wlan0 (which failes if interface exists) and/or wait for its creation/driver own…
so if you want to use the internal wifi on r2 (like me), make sure, there is no wlan0 before starting wifi.sh
debugged so far…
rootcause is adding a handler to wrong netdev searched with hardcoded wlan0 in drivers/misc/mediatek/connectivity/common/conn_soc/linux/pub/wmt_chrdev_wifi.c
#define WLAN_IFACE_NAME "wlan0"
static INT8 *ifname = WLAN_IFACE_NAME;
netdev = dev_get_by_name(&init_net, ifname);
pf_set_p2p_mode(netdev, p2pmode);
Currently i have no idea how to pass the wifi-devicename created in gl_init.c to wmt_chrdev_wifi.c
I tried to write a get_netdev function which tries wifi9 down to 0,but i get still an error which i need to solve…maybe because i try to set ifname which is a int8 * and no char*
Good news, i tested vendors 4.14 for client mode and it works. Ap too…and the best: it seems to be based on my codebase,as i see my debugs,i’ve disabled later. That makes it easy to find possible fix for client-mode. I make some tests and apply the fix to all lts/main branches if ready
mhm, in 5.10.32-bpi-r2-hnat, client-mode is working
difference to ap-mode:
/etc/wpa_supplicant/wpa_supplicant.conf:
network={
ssid="ssid"
psk="12345678"
priority=1
}
wmt_loader and stp_uart-launcher needs to be called before, and needed modules loaded (wifi/BT)
instead of echo A we do echo 1 here:
echo 1 >/dev/wmtWifi
wpa_supplicant -i mt6625_0 -c /etc/wpa_supplicant/wpa_supplicant.conf &
dhclient mt6625_0
i got ip-adress from my dhcp-server (dnsmasq) and can ping it (of course wan/lan-disconnected)

Hey, thanks to Franks wiki I got the internal WiFi working to connect to my main network. Unfortunately it seems that the internal WiFi also likes to change MAC address on boot. Is there a way to hardcode the MAC adress of the internal WiFi? I have seen the instructions for the Ethernet ports (though I am not sure if they currently work correctly), but because the way you have to bring up the mt6625_0 device, I have not found a way to set its MAC address.
Imho udev way should work for wifi too. For client mode match mt6625l_0 and for ap-mode ap0
You can write sh that can chnage mac on run/ boot. Just need to ifconfig ap0 down. Ifconfig ap0 hwadress MAC. And start the ap0.
Right…you can add it to the wifi.sh before doing anything with ap0…if using ap-mode
Currently I try to use it in client mode. I use the systemd script to start the device, which works:
root@bpi-r2:~# ip link show mt6625_0
9: mt6625_0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether 00:08:22:60:d1:fb brd ff:ff:ff:ff:ff:ff
wpa_supplicant is setup and using dhclient mt6625_0 lets me connect to my home wifi successfully.
I’m running kernel bpi-r2 5.4.134-bpi-r2-main
I have set following udev rule:

I hope I’m just making a stupid mistake. Thanks for your help in advance!
maybe this MAC is dropped because it is invalid? but wonder why it works the first time. maybe you should use INTERFACE instead of KERNEL
INTERFACE is not shown as an identifier here:
root@bpi-r2:~# udevadm info -a -p /sys/class/net/mt6625_0
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Unload module index
The command to set the mac does not appear.
I tried with a different mac instead: ACTION=="add", SUBSYSTEM=="net", KERNEL=="mt6625_0", RUN+="/sbin/ip link set dev %k address ba:de:af:fe:13:37" (this should be valid, it is not a multicast address and it is a local-only mac address)
This does verify again with udevadm test, but does not set the mac.
Changing the mac addresses of the other ports does work just fine:
ACTION=="add", SUBSYSTEM=="net", KERNELS=="1b100000.ethernet", RUN+="/sbin/ip link set dev %k address ba:de:af:fe:ff:ff"
ACTION=="add", SUBSYSTEM=="net", KERNEL=="lan0", RUN+="/sbin/ip link set dev %k address ba:de:af:fe:00:00"
ACTION=="add", SUBSYSTEM=="net", KERNEL=="lan1", RUN+="/sbin/ip link set dev %k address ba:de:af:fe:00:01"
This gives every adapter connected to eth0 the address ba:de:af:fe:ff:ff and lan0 ba:de:af:fe:00:00 as well as lan1 ba:de:af:fe:00:01 :

I feel like the issue must lie deeper, but the only info I get is

I do not know where to go from here.
ok, then KERNEL is right…maybe interface is not in down state when udev triggers? how do you run the wmt-commands? imho it’s easier to put your command there before set interface up
Right now I tried manually bringing up the device (I disabled the systemd script which I used so far):

RTNETLINK answers: Operation not supported
The earliest the mt6625_0 device appears, is after executing echo 1 >/dev/wmtWifi.
It is a bit annoying, because I can use the internal WiFi for networking, but having a static mac address would save me a few headaches ^^
Do you really have random mac? Comment in nic_cmd_event.c means it is copied from firmware.
Maybe you can add some debug?
This looks related
It seems to me to be random, at least the last three octets change. After preparing the adapter with wmt_loader and stp_uart_tools, I have tried
echo 1 > /dev/wmtWifi
ip a
echo 0 > /dev/wmtWifi
a few times and everytime the mac changed:
00:08:22:22:40:fd
00:08:22:80:04:fe
00:08:22:41:e9:fe
00:08:22:c0:63:ff
After rebooting:
00:08:22:3e:25:fc
00:08:22:10:a8:fc
I will try to look into the code over the weekend, maybe your hint can help. I can also add dmesg output tomorrow. Thanks again for helping and looking into the issue!
