LibreELEC 9.2.1 can't connect to wifi on Raspberry Pi 4 model B

Quote from urig

Hi,

I've installed LibreELEC v9.2.1 on my Raspberry Pi 4 model B (4GB). It boots nicely but I can't connect to my home wi-fi router.

Here's what I'm doing:

1. I go to Settings > LibreELEC > Connections
2. My router's SSID is shown, having the strongest signal
3. I choose it and click Connect
4. I enter my wi-fi password
5. I see the status changing from 'idle' to 'association'
6. After a few seconds it changes back to 'idle'
7. I try connecting again. I'm not prompted for a password
8. I see the status changing from 'idle' to 'association'
9. After a few seconds I'm shown a Network Error saying 'Input/output error'
10. The status changes back to 'idle'

Am I doing it right? What am I missing?

Thanks,

urig

PS - I'm setup for WPA2-PSK but I see no mention of this in the LibreELEC GUI

The 2.4 Ghz band has better penetrating power for a given distance than the 5.8 Ghz. As suggested by Da Flex, try a different wifi band. Wifi signals are similar to a flashlight (torch in the UK). Try: different orientations of the wifi router, possibly its antennas, reducing the distance between the RPI and the wifi router.
