+RTL8731BU and RTL8733BU are very small WiFi chips, so RTL873xBU-based net cards are really small, because of that they are extremely popular for tinywhoops. But RTL873xBU-based net cards **AREN'T SUITABLE FOR LONG RANGE AND RX USE**. 5MHz, 10MHz, 20MHz, 40MHz modes are supported.
+:::caution
+40MHz mode supported by driver, **your** net card might not support this mode. Please contact seller before buying net card. Please add your net card to list of RTL873xBU-based NICs below.

+:::caution
+If you don't receive image after switching on 40MHz mode, please read this [article](/use-cases/fpv/unbrick-eu-bu/) to fix your issue.

+## What happened?
+**All** EU-based net cards can not transmit at 40MHz, **some** BU-based net cards can not transmit at 40MHz. When you forcibly enable 40MHz mode on those net cards - your RX can not receive signal. Please check the information about your network card in the "Net cards" section, the specifications list all supported modes.
+
+## What you need to unbrick VTX.
+     -     PC with installed [OpenIPC Configurator](https://github.com/OpenIPC/openipc-configurator).
+     -     Bricked VTX.
+
+## How to unbrick.
+     -     Connect your VTX to your PC using Ethernet(or debug port) to PC.
+     -     Configure your Ethernet connection(read [Advanced setup guide](/use-cases/fpv/advanced-setup/)).
+     -     Update firmware on your VTX using OpenIPC configurator(read [Advanced setup guide](/use-cases/fpv/advanced-setup/)).
+
+:::caution
+Do not interfere during update process!! Do not unplug battery! Do not unplug Ethernet cable! Do not turn off your PC!
+:::
+
+:::caution
+Please wait additional 10 seconds after "Firmware upgrade completed successfully." message.
