Issue connecting to Wifi via WPA2 on openwrt

[vbarter]

Hello,

I'm having issues connecting my Raspberry Pi 4 to my wifi network. I have 2 radios, both on WPA2. Screenshot of my openwrt settings below. What settings do I configure for the dietpi-wifi.txt file? Do I have to do WPA-EAP instead? If so what do I fill in? It was minimal setup on my router for WPA2.

Code: Select all

# Entry 0
# - WiFi SSID: required, case sensitive
aWIFI_SSID[0]='Wireless'
# - WiFi key: If no key/open, leave this blank
aWIFI_KEY[0]='
# - Key type: NONE (no key/open) | WPA-PSK | WEP | WPA-EAP (then use settings below)
aWIFI_KEYMGR[0]='WPA-PSK'
# - WPA-EAP options: Only fill if WPA-EAP is set above
aWIFI_PROTO[0]=''
aWIFI_PAIRWISE[0]=''
aWIFI_AUTH_ALG[0]=''
aWIFI_EAP[0]=''
aWIFI_IDENTITY[0]=''
aWIFI_PASSWORD[0]=''
aWIFI_PHASE1[0]=''
aWIFI_PHASE2[0]=''
# - Path to the certificate file, e.g.: /boot/mycert.cer
aWIFI_CERT[0]=''

No, you don't have WPA-EAP, use the WPA-PSK.
Be careful cause you have posted the WPA Key in the post above.

For further troubleshooting post from OpenWrt the `uci export wireless` (redact the WPA keys from there as well)

Hi,

Many thanks for your message. Is DietPi already running? Or do you like to configure WiFi together with the initial setup?

I ended up switching one of my WiFi settings to be WPA-PSK on the router for the 2.4 band, so I’m setup and running on that.

My question is how can I connect to my 5.0 band network that now runs with WPA2/WPA3? It seems like only WPA-PSK security works and nothing higher with just using a password

Hi,

I tested it with my RPi3B+ without issues. I created an unique 5GHz WiFi using WP2/WPA3 and could connect with the RPi using WPA-PSK without issues. The RPi was connected using WPA2.

Hey so I tried changing my 2.4 network to be WPA2-PSK and that worked fine... but I still can't connect to my 5.0 network on WPA2.
I tried switching my 5.0 network to WPA-PSK and that connected fine, but WPA2 I'm still having issues.

What am I missing? Below are the 2 commands you ran:

So I got my WPA2 to work, I had to add freq_list= to my wpa_supplicant

Here's the example:

Code: Select all

# Grant all members of group "netdev" permissions to configure WiFi, e.g. via wpa_cli or wpa_gui
ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev
# Allow wpa_cli/wpa_gui to overwrite this config file
update_config=1

freq_list=5170 5180 5190 5200 5210 5220 5230 5240 5260 5280 5300 5320 5500 5520 5540 5560 5580 5600 5620 5640 5660 5680 5700

network={
        ssid="Wireless 5.0"
        scan_ssid=1
        key_mgmt=WPA-PSK
        psk="XXXX"
}

What channel you are running the 5GHz Network? Mine is running on channel 36.

I had issues on other channels for sure, 36 was best
