Can't connect my network #129

Hello, my emonPi device currently has an error that cannot connect to the network as follows.

The first is about the configuration information I'm using:

My current problem is as follows:

I have reinstalled the operating system with the latest version as described above. I have seen the installation instructions of emonPi on its website and I follow the steps as above.

After booting, the LCD screen of emonPi shows the IP address 192.168.42.1 and I connected to the wifi network of emonPi and connected to my Wifi network. After doing the above, the device reboots on the LCD screen and after reboot it shows "Ethernet not connected" on the LCD screen. I tried other times the same with wired LAN, 2.4GHz - 5.0GHz wireless network and even after every try I reinstalled emonPi's operating system. However, the same results are all not connected to the network. I use emonCMS, Fing to scan and find emonPi IP in my network, I can't see it, and I also use PuTTy to connect SSH with emonPi but it doesn't work.

I tried connecting my monitor to emonPi via the HDMI port of rasberry3 and I entered the command ifconfig and iwconfig both showed no connection to the network.

During the device reboot after connecting me to wifi for it through 192.168.42.1, I pinged the device, the result showed that the device can only ping in a very short time after that's impossible to ping completely, the failure rate is 98%.

Don't know what this error is and how to fix it. Thanks.
