Technical FAQ

How can I access the dashboard?

Check the screen of your Bitaxe & NerdQaxe++. There will be an IP address (such as 192.168.18.21) displayed if it is connected to the WiFi successfully. Enter this IP address in the Internet browser (such as Google Chrome, Firefox, Brave etc). Make sure to be connected to the same WiFi network as your miner. Try with other browsers if one does not open up the dashboard.

What to do if my miner is not connecting to the WiFi?

You can try the following things:

• Check if the name (WiFi SSID) and password is correct.

• Disable VPN if you have one.

• Try connecting to a phone hotspot to check if it works (if you are using iPhone, please enable “Maximise Compatibility" under Personal Hotspot settings).

What if my miner is connected to the WiFi, but not hashing?

If your device is connected to the WiFi and you can access the dashboard please double check if your pool settings are correct (Stratum Host & Stratum Port). Make sure to copy the Bitcoin address (Stratum User) without any mistakes. If any of these settings are incorrect, the device will not mine.

What if my NerdQaxe++ overheats?

NerdQaxe++ most often overheats due to hot voltage regulators. You can move the fan slightly upwards so more air blows past the heatsink onto voltage regulators. It is also possible to attach an additional fan to cool the voltage regulator area.

What if something is wrong with NerdQaxe++, but I don't know what?
