Addressing Special Characters in SSID with wpa_supplicant

In some instances, special characters within an SSID can lead to issues when utilizing wpa_supplicant. If you're encountering problems connecting to a Wi-Fi network with a special character-infused SSID, consider these effective strategies:

Identifying the Correct SSID Name

1. Scan for the BSS:

   iw dev wlan0 scan
   

OR

   wpa_cli -i wlan0 scan_results
   

2. Retrieve SSID using BSS:

   wpa_cli bss 11:1a:aa:ff:ff:ff | grep ssid
   

Replace "11:1a:aa:ff:ff:ff" with the BSS obtained from the previous step. 3. Utilize the Correct SSID Name in wpa_supplicant.conf: Ensure you use the SSID name retrieved in the previous step within your wpa_supplicant.conf configuration file.

Employing Hex Strings for Special Characters

network={
    ssid=00010203
    psk=6173632761736361737363c3a461
}
