Hi,
On the Edup Ax3000 USB adapter plugged in USB 3 port of D-Link AC2640 running OpenWrt 23.05.4 r24012 Kernel 5.15.162 , I'm encountering issues:
1- where the Maximum transmission power is locked always at 3dBm on 5GHz no matter how I tried to change it.
2- I read that Wi-Fi 6e will not function as AP any work around? is it a driver issue or platform.
3- Fast roaming is present in the device configuration and ticked but it seems not working.
The driver is WIFI_MT7961_patch_mcu_1_2_hdr.bin and it's firmware were manually installed and automatically from the package repository as of kmod-mt7921u.
Side question will replacing the 6dBi with12 dBi RP-SMA antennas make any performance difference,
in advance and regards,
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network

cat /etc/config/dhcp

lsusb
lsusb -t
- Are you sure it's 3dBm? Have you actually compared rx power on a client device with another AP that properly reports tx power?
- Have you tried starting an AP in 6GHz? It should work as long as you set up the country correctly and use WPA3 EAP, SAE or OWA
- Fast roaming should work fine, I tried it on a MT7921K (RZ608) PCIe device and it works fine as that is not a hardware feature - it's implemented in hostapd.
The actual problem I see with using these as AP (aside from using USB for an AP device - it will perform terribly especially on not-so-fast MT7621 SoC) is that it only allows 15 devices in total to connect, and doesn't support multiple SSIDs.
Have you also tried with a snapshot build?

I hope it is formatted it's my first time to post here in the forum thank you,

Thanks for the reply,
-
From Luci Wireless overview then edit the SSID of the MediaTek MT7921AU 802.11ac/ax/b/g/n Radio it shows the current power of 3dBm, It is never changed.
-
When I start the AP in 6GHz the SSID disappear while I set the country to SA.
-
The client "My phone" roam perfectly when I go away from the D-Link and get closer to the Asus AX53U, but with the Edup it keeps connected.
-
I just need it for max of 2 or 3 devices. Cause the Wi-Fi 5 on the D-Link is sometimes unconscious
-
I didn't try it on a snapshot build for two reasons I don't know how and it has the NAT role so I can't stop the home network.
Your country doesn't have 6GHz in linux wireless regulatory database.
It should, in main snapshots.
Seth Forshee handed wireless-regdb maintenance over to Chen-Yu Tsai, so the git tree to look at is:
https://git.kernel.org/pub/scm/linux/kernel/git/wens/wireless-regdb.git/tree/db.txt?id=003c282a297f8cec06a576fe1434c94353d14610#n1657
The version of wireless-regdb in snapshots is 2024.07.04-r1, which does contain
https://git.kernel.org/pub/scm/linux/kernel/git/wens/wireless-regdb.git/commit/?id=04875d9b62c3faf27d4164d22f025b6bb77dd0af
(it's a relatively recent addition, but it's in main's version of wireless-regdb).

It's a display issue, driver developers already noticed about that, it won't affect normal usage (i.e. the actual transmitting signal is not 3dBm)
I remember I tried it and managed to make it working once, however I think the default wpad package coming with the OpenWrt firmware might need to be replaced.
It's designed as a client device, so I really doubt this would show significant improvement.
