[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.

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
