Raspberry Pi 4

Port Layout

Troubleshooting

Restarting on Large Downloads or Livestream Test

This indicates a poor power supply. Use the official RPi power supply or a 5.3V adapter with a USB-PD Type-C cable.

Red LED Flashing Erratically

This also indicates a poor power supply.

Unable to Connect to "SmoothWAN Setup" SSID

Set up in close proximity to the Pi. Signal strength is not a reliable indicator to use.

Note

The RPi's internal Wi-Fi "ACK-drop" interval is very short and not adjustable, dropping far clients as a result.

Use it for managing the device only.

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