+The SSID is case-sensitive. Both for SSID and the password, special characters should be escaped with a backslash (''\'').

 Upon connecting successfully, the Wi-Fi icon will appear in the top-right of the screen (certain themes may reposition this).

 ===== Troubleshooting =====
+==== Wi-Fi is not working ====
 After activating Wi-Fi, it may take a moment to actually activate. In fact, it might not even activate until the system is rebooted. The power of Linux! Reboot and try again. It might even be worth waiting around ten seconds or so on the main menu before going into the Wi-Fi menu.
+It could also be that your Wi-Fi chipset requires particular drivers not already included in Batocera. Check [[#how_to_manually_add_drivers_(advanced)|the section on how to do that below]].
+==== I can't see my SSID in the list, but I can see my neighbor's ====
+It's possible that the device you are using Batocera on is not compatible with the channel that your router is set to use.
+For instance, the Raspberry Pi line infamously does not support channel 13 on the 2.4GHz Wi-Fi.
+The [[https://openwrt.org/docs/guide-user/network/wifi/wifi_countrycode|country region]] can be altered in ''batocera.conf'' by adding the ''wifi.country'' key and making it equal to your country's region code. For example: ''wifi.country=US''.
+What if you don't know your country's code? Use the **Alpha-2 code** from this list: https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes

   * Turn off as many other Wi-Fi enabled devices as you can, including your phone, your smart thermostat, your fridge, etc.
   * Turn off any large mechanical devices that throw out lots of interference like combustion engines, generators, UPS's, microwaves, etc.
+  * If using 2.4 GHz Wi-Fi (the "default" for most routers) make sure you aren't using any USB 3.0 devices as [[https://superuser.com/questions/1282590/why-does-usb-3-0-interfere-with-2-4ghz-devices|they can cause direct interference]].
   * Try to have a direct line-of-sight to your router. If that is not possible due to a wall being in the way, try to have the least amount of objects between the device and the router.
     * Usually, the best place for the router is very high above the ground, as there are less things on the ceiling than the floor.

 You can disable the Raspberry Pi 4's onboard Wi-Fi by adding ''dtoverlay=disable-wifi'' to ''/boot/config.txt''.

+==== How to manually add drivers (advanced) ====
+Most network devices should already be [[hardware:compatible_dongle_list|supported by the Linux kernel included in Batocera]]. However, in some rare cases (such as bleeding-edge hardware) the drivers might not be included yet. If the manufacturer has provided pre-compiled binary driver files, it is possible to install them.
+If your network/Wi-Fi device complains about requiring certain binary firmware files (check with ''dmesg'' [[:access_the_batocera_via_ssh|via terminal]]), you can [[:modify_the_system_while_it_s_running|put them into]] ''/lib/firmware/rtlwifi/'' and run ''batocera-save-overlay'' after confirming it works.
+An example of a Wi-Fi device complaining about binary firmware files in ''dmesg'':
+<code>
+[ X.XXXXXXX ] Wi-Fi: xxx0: RTL: firmware file rtlwifi/XXXXXXXXXX.bin not found
+</code>
+<WRAP center round tip>
+If you've done this and it worked successfully, let the devs know so they can add it to the next version of Batocera.
