I have experienced the same issues I was claiming before but now I have found the culprit.
In first tests I have stupidly forgot to mention that I also had a USB3.0 Stick connected to the router. A decent USB stick from San Disk 32GB link here .
After I have updated to fw 4.2.0 beta 2 I have not connected the usb stick to the router.
All my tests after the update were without the usb stick and jus tnow I have plugged the USB stick and the entire network became unstable. The 5GHz SSID was appearing and disappearing and the 2.4GHz SSID associated IoT devices started to connect and disconnect. I have removed the USB stick after a few minutes and immediately the router returned to normal. I have attached here the kernel leg between plugging the USB stick and disconnecting the usb stick. It ended up being a 24page long log so whoever will read it will need a beer or a coffee
I am using a different adapter as I need a longer power cable.
I use this power adapter with a 2m cable that is 100W emarked and tested to carry up to 100w. So basically the power shouldn’t be an issue unless the router has difficulty to handle the PD standard but as it powers up when connected to the emarked cable, I assume the implementation of the PD standard is good or it is using 5.1k resistors on the PD line which will give it 5V and 3A .
Software version 4.4.5
a few days ago everything was ok. Today I wanted to scan the list of available wifi networks and it doesn’t find any one. When adding a Wi-Fi network manually, I also cannot connect. I decided to restore the factory settings, after logging in again there was still no wifi available.
I have a Mudi 750 router turned on next to it, so I can see many networks available. On the mt3000, none of them.
What could be the reason?
