[Banana BPI-R4] Wifi7 status

Betonmischer · April 15, 2025, 3:30pm

In fact, I created a patch to iwinfo which resolves the issue by filtering survey dump entries by frequency. Only for the NL80211 backend, though, but I'm not sure the other ones a still relevant.

There we go, different noise values now.

Can somebody help me with this hostapd.conf content who has MT7x MLO setup?
Please.

Thnx.

gsustek · April 15, 2025, 11:17pm

it works. 6GHZ ... THNX sooo much!

if somebody has just wifi module with just one phy and multiple band's, please share hostapd.conf.
You can verify it via iw list command.

Betonmischer · April 16, 2025, 10:23am

May I suggest you create a separate topic for your issue, since you're not using the stock BPI-R4 Wi-Fi module (the BE14, which is, somewhat confusingly, missing from the title of this one), and also be more descriptive of what you're trying to achieve? That way it'll be easier for others to notice it and offer help.

EPinci · April 21, 2025, 9:59pm

Where do I place this patch file to test it out?
Thank you.

Betonmischer · April 21, 2025, 10:18pm

Put it into package/network/utils/iwinfo/patches/ and name it something like 101-xxx.patch. The "101" is important, as there is already a patch starting with a "100".

Zasranec · April 27, 2025, 7:10am

Has anyone been able to get MLO to work on the latest snapshots? Wifi7 is also not working properly....

danpawlik · April 27, 2025, 10:20am

On latest snapshot... Nope. But you can try community folks build from [Banana BPI-R4] all related to MTK-SDK

BuzzBen · May 2, 2025, 8:55pm

If any of you are playing with SFPs I made a new post because I need help [Banana BPI-R4] SFP Status - For Developers - OpenWrt Forum

Thanks

chorturtle · May 5, 2025, 10:58pm

Has anyone actually confirmed / tested the claim on the wiki page that the background radar is supported on the BE14 2+3+3 and it's not just a placebo (since setting it does nothing if the underlying hardware doesn't support it)?

I don't see background radar support listed when I do "iw list" or in the mt76 code..

SpectreDev · May 6, 2025, 7:18pm

Just to say the issue with BPI 4 "penetration" is false, it's power amplifier is perfectly fine, the issue is in the noise levels being high

Giorgik · May 6, 2025, 8:14pm

What are you basing your claim on? My short experience with BE-14 was that it's BOTH: The transmitted signal strength is much lower than advertised 25/27dBm even with the TX power patch applied and simultaneously the noise floor is also very very high.

I used an android phone with Wifi Analyzer app to compare my old Linksys WRT1900AC signal strength with the BE-14 in the same exact spot and on the same exact channel on 2.4 and 5GHz.

SpectreDev · May 6, 2025, 10:29pm

You would need to use professional equipment to validate that claim, because as as I'm concerned in house there's no issue with the signal strength I get full bars everywhere the issue lies in signal noise

Giorgik · May 6, 2025, 10:37pm

Very interesting. I definitely get less bars with BE-14 on my laptop, both phones and the PC as well as 10dBm+ difference in reported signal strength by various IoT ESP8266 devices.

What OpenWRT build do you use?

EDIT: This user's post on Banana Pi official forum contradicts your statement: https://forum.banana-pi.org/t/bpi-r4-wifi-range/19418/107

It sounds like Sinovoip directly confirmed to this user that there's an issue with BE14 chip and that the power amplifier on the chip isn't powerful enough.

SpectreDev · May 9, 2025, 8:41am

The comment under it explains the problem

phil2sat · May 9, 2025, 9:01am

I read the last couple of days before deciding to buy the device with the BE 14.
for what i found out is new mt7996_eeprom_233_2i5i6i.bin without any patches should resolve txpower issues in actual snapshot.
BUT
even if the signal is good the rate is poor like 1-30mbit/s (should be fixed by using wpad-openssl)

since i plan to buy im actually testing image build including this fixes, if interrested say it, but i cant guarantee that it even boots, but it should...
i have also a 8gb variant handy, needs to be tested...

SpectreDev · May 10, 2025, 8:40am

The speed is fine tbh I get full 800mbps in my house, the issue it suffers from is noise

sfx2000 · May 11, 2025, 1:19am

Yeah - I've never indicated that Wireless is broken - perhaps sub-optimal, but it is functional enough for platform work...

My point was that it's a development board - temper this as it's not necessarily of production/commercial level...
