Troubleshooting

Restarting on large downloads or livestream test

Indicates poor power supply, use the official RPi power supply or a 5.3V adapter and a USB-PD Type-C cable.

Red LED flashing erratically

Indicates poor power supply.

Unable to connect to "SmoothWAN Setup" SSID

Setup in close proximity to the Pi, signal is not an indicator to use.
Cause: RPi's internal Wi-Fi "ACK-drop" interval is very short and not adjustable.

For maximum stability, you can reduce power consumption as well as performance (~180-Mbit) by editing config.txt in SD and adding arm_freq=1000 at the end of the file.
