Troubleshooting • Re: Raspberry Pi 4 Won't Connect To Wifi No Matter What

So the first thing you need to do is run the following commands at the command line or terminal window and post the results , so we have at least some information to work with.

Code:

ifconfigrfkill list allsudo iwlist wlan0 scan
secondly you say the wired networking will also not work if you connect the pi to a router using a known good 8 wire LAN cable what do the leds on the pi LAN port do and what to the corresponding leds on the router do ?
Here is the result of the commands:

Code:

ifconfigeth0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500        ether d8:3a:dd:48:7d:d5  txqueuelen 1000  (Ethernet)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536        inet 127.0.0.1  netmask 255.0.0.0        inet6 ::1  prefixlen 128  scopeid 0x10<host>        loop  txqueuelen 1000  (Local Loopback)        RX packets 25  bytes 2590 (2.5 KiB)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 25  bytes 2590 (2.5 KiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500        ether d8:3a:dd:48:7d:d6  txqueuelen 1000  (Ethernet)        RX packets 0  bytes 0 (0.0 B)        RX errors 0  dropped 0  overruns 0  frame 0        TX packets 0  bytes 0 (0.0 B)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0rfkill list all0: phy0: Wireless LANSoft blocked: noHard blocked: no1: hci0: BluetoothSoft blocked: noHard blocked: nosudo iwlist wlan0 scanwlan0     Interface doesn't support scanning : Connection timed out
Regarding the Ethernet issue, I actually haven't tried connecting my Raspberry Pi to the internet using a LAN cable. I mention the Ethernet issue because when I attempt to link the Raspberry Pi to my laptop, VNC and SSH are not working.
