-If there are other 2.4GHz devices (WiFi, Bluetooth, etc.) around there might be running on the same channel so try switching it in the [[projects:crazyflie:pc_utils:qt_ui#configuration_block|bootloader configuration block]]. You might have to switch a few times fore you find a good one. You can also try adjusting the radio bandwidth. If you set it to 250kbit/s you will get good range outside but inside the reception/range might become worse. Since the rate is lower the data spends longer time in the air which increases the probability of interference. Changing the speed to 1Mbit/s or 2Mbit/s will give better results under these circumstances.+If there are other 2.4GHz devices (WiFi, Bluetooth, etc.) around there might be running on the same channel so try switching it in the [[doc:crazyflie:client:pycfclient:index#configuration_block|bootloader configuration block]].

 If you get errors during the upgrade or you upgrade to your own custom software that has bugs you might not be able to start the firmware. The typical behaviour for this during power on is that the red/gre LEDs blink and then nothing else happens. No sensor test is run (i.e no more blinking LEDs) and you cannot connect with the Crazyradio. If you get errors during the upgrade or you upgrade to your own custom software that has bugs you might not be able to start the firmware.

-When upgrading the firmware the bootloader cannot be overwritten or modified so you always have the option of going into bootloader mode and upgrading the firmware again. [[projects:crazyflie:pc_utils:qt_ui#bootloader|Here]] are the instructions for upgrading the firmware.+When upgrading the firmware the bootloader cannot be overwritten or modified so you always have the option of going into bootloader mode and upgrading the firmware again.
