I have no mt7615 card…but tested an mt7612 and ath10k some time ago (imho before 5.4 was out)
I used mt7622 AP to connect / disconnect continuously with my mobile phone for hours, but couldn’t reproduce that connection issue. BTW, could you please enable the firmware debug log after boot up? Need to check if client is added/removed to/from staList correctly every time.

Hi, I guess the root cause is MSI. please try this patch https://patchwork.kernel.org/patch/11494641/
@Ryder.Lee Attached logs from FW.
MT7622_WIFI_FW_debug.7z (40.7 KB)
I restart R64 overnight and at the morning I was not able to connect to wifi even with devices that was connected before. If need more tests I will leave it running in that state for next few hours.
Thanks. I’ve co-worked with @Kosyak to reduce debugging scope today (in mt76-devel irc channel). I will make a patch to check sta_add flow soon.
I’m trying to include the patch you mentioned in the build, but my knowledge and understanding is simply not enough to get things right.
I had to make some modifications to the patch itself since it failed to apply to mt7622-rfb1.dts. I rewrote the section this way:
diff --git a/arch/arm64/boot/dts/mediatek/mt7622-rfb1.dts b/arch/arm64/boot/dts/mediatek/mt7622-rfb1.dts

But now I have this error upon build:
Error: /home/parallels/bpi-r64/openwrt/build_dir/target-aarch64_cortex-a53_musl/linux-mediatek_mt7622/linux-5.4.42/arch/arm64/boot/dts/mediatek/mt7622-elecom-wrc-2533gent.dts:168.1-6 Label or path pcie not found
FATAL ERROR: Syntax error parsing input tree
I figure it’s due to the following section in the mt7622-elecom-wrc-2533gent.dts file, but I don’t know what should I write there instead.
&pcie {
pinctrl-names = "default", "pcie1_pins";
pinctrl-0 = <&pcie0_pins>;
pinctrl-1 = <&pcie1_pins>;
status = "okay";
pcie@0,0 {

mt7615@0,0 {
reg = <0x0000 0 0 0 0>;
mediatek,mtd-eeprom = <&factory 0x05000>;
};
};
};
&pcie should probably be renamed to &pcie0 but what to do with the other lines?
Any advice?
Why not just disable the block with /* */ ? This dts is not needed for r64
Thank you. I renamed &pcie to &pcie0 just to make it compile.
But now it looks like that I’ve lost mk7615e completely.

};Dts looks right…from your dmesg it looks like both ports are down…maybe something power-related? Can you compare your dtsi with mine (5.4-main branch except switch driver)? Have you added the other patches i’ve mentioned (irq handling, class fix)?
Looks like I found the culprit.
I just needed to apply all four patches from Spilt PCIe node to comply with hardware design series. I had to make some modifications as I mentioned above since mt7622-rfb1.dts from OpenWRT is a little bit different from what the patch is expecting (see attachments).
1002_1-dt-bindings-PCI-Mediatek-Update-PCIe-binding.patch (9.0 KB)
1002_2-mediatek-Use-regmap-to-get-shared-pcie-cfg-base.patch (2.7 KB)

1002_4-ARM-dts-mediatek-Update-mt7629-PCIe-node.patch (2.0 KB)
BTW is there a more elegant way of obtaining these patches rather than select - copy - paste to text editor - save as .patch - put in patches-5.4 dir?

Two things bother me though.
- For some reason OpenWRT generated config files in such a way that
radio0iswlan1and vice versa. - Txpower on both cards seems to be limited to 6 dBm. Is there a way to increase it?

Nice to see there is an official patch now…i got them here or by email and collected over time 
I don’t know if openwrts build-system can handle mbox files…then you can click “series” button in the upper right corner if patchwork site to download a “git am” compatible file with all patches from the series
Maybe you can change that by modifying udev-files.
There is a discussion about the 6dbm issue,but afaik no working solution…here is a hint why this happens,but afair patch was bot accepted and maybe not compatible with mainline code
@svintuss As for 6dbm limit. Compile mt76 driver with eeprom.c from git on top of this thread. This is working for me on mt7622. I do not have 7615 so cannot check.

After replacing eeprom.c mt7615 is non-functional: It became a clone of mt7622 device (same MAC, system thinks it’s 2.4 GHz).
Compare this output to my previous post: ifindex, wdev and addr are different.

0 0 0 0 0 0 0 0 0I’m sure this is because the fixed eeprom-data in mt76_get_of_eeprom called for every device handled by the driver
Do you see your mac-address? 
This function should be called only for mt7622 wifi and not mt7615…
If i see this you see that with the eeprom-data all cards will be handled as 7622 because of first 2 bytes
You need something like this in mt76_get_eeprom function:
switch (mt76_chip(dev)) {
case 0x7622: /*here existing content*/ break;
case 0x7615: /*eeprom data for 7615*/ break;
}
But make sure function returns 1 else it will break mt76_eeprom_init…

Thank you, @frank-w. Do you have any ideas where can I get eeprom data for 7615?
@niebieski20 where did you get mt7622 eeprom?
You can skip the eeprom part for mt7615 in a first step (only write eeprom data for mt7622) but let function return always 1. I guess he used the eeprom-data normaly written to mtd partition in openwrt
have modified eeprom.c like i’ve mentioned…
eeprom.c (7,3 KB)
Thank you.
Am I getting this right?

Can images from this post be of any help in extracting mt7615 eeprom? Full support for mt7615 WiFi is claimed.
lspci in this LEDE image looks like this.

i think you do not need any additional eeprom-data, because card should have it’s own burned onto it. i had also used mt7622 without any additional eeprom-data, but i have no mt7615 which may breaḱ and have not yet looked at the 6dbm-issue (i guess eeprom-data is fix for this)
