On my device, with OpenWrt 23.05.2, and today updated feed, i have problem.
Computers connect, but new phones such as the samsung S24plus cannot connect.
It says unable to connect, or says nothing at all.
It did no good to put the fixed channel, the static ip in the phone, or to change other parameters.
Is there any known incompatibility problem?
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:

It appears you are using firmware that is not from the official OpenWrt project.
When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.
You may find that the best options are:
If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.
If it was generic OpenWRT - would be advisable to clear txpower restriction to take max of what radio supports and set country code for both radios in place of NOSCAN options.
Highly advisable to have both radios emit same access point and access credentials (none in your case) to have continuous coverage area.
It is a standard compilation of openwrt.
I just made a custom dts to handle leds and buttons, and ad vitriol settings.
The MT7620 only has a 2.5Ghz radio, the 5Ghz radio is a USB stick, normally not present.
The power has been reduced to reduce noise on the board.
However, this thing is used 1m away from the smartphone.
Even if I put the country, the problem is not solved.
I cannot use a pre-compilation.
I don't have a Samsung S24 ultra and I can't give a firmware without settings to the overseas customer.
That makes you first and last support forum for the software, not us.
If you wish to make it official just submit https://openwrt.org/docs/guide-developer/add.new.device device support and all you have to do is to add uci-defaults script to set up "factory defaults" on reset.
I am sure the problem is the wifi driver.
How can I propose my dts to be added to managed models?
I produce two devices, with OpenWRT, with almost nothing custom.
Custom there is only the DTS, the configuration and some .sh scripts to control the LEDs.
I would like to include them in the official list.
I've been trying to find time for a year to study how github's pull/commit works, and I still haven't found it.
Is there an easier way?
Custom is xilinx sdk, looks like opensource mt76 driver. You need to build regdb signer key into kernel and sign regdb, or use default db from kernel.org with pre-builtin keys.
Try to explain better that I didn't understand.
The radio is inside the single chip MediaTek MT7620
I made:
git clone
add dts and other
make menuconfig
make

Ask xilinx to spoon-feed wifi basics. Wifi works on official openwrt.
There is nothing xilinx about this object.
I can't understand it.
There is only a mediatek CPU soldered on the PCB by me
I dont understand myself, i think i saw it somewhere else.
You need to add wireless regdb and set country code. It will start to work. Note rhe global domain by default has all world restrictions just to poc you can connect.
If you mean this, it is already activated.
The customer tried setting the country code to Italy, and also the fixed channel to 6, but did not solve it.
This is my board, my design and my production.
Battery PoE and WiFi
A customer solved the problem with this configuration.
Can you tell me which of these could be the resolution?
He had already tried setting the contry code to IT and it didn't solve it.
I also send it worldwide and find it difficult to set the country code.
Radio1 is a 5Ghz USB stick that had the same problem.
I also have a doubt about how I configure the mac, what is the correct way?

I finally found a phone that does that problem.
I found that it was no configuration change that solved the problem.
I solved it by setting the gateway in the phone.
My device has no DHCP, to use it you set static IP in the phone.
Normally the phone associates, writing connected without internet.
On some recent phones, however, it doesn't stay associated, unless you set the IP of the device as gateway.
It seems that some versions of Android and perhaps IOS, if they can't find the gateway IP, refuse the connection.
Will there be a solution for this?
Ask google, most phones ask to stay connected, you need p2p aka wifi-direct to stay connected without prompt or int3rnet.
