Tips & Troubleshooting

Using the Raspberry Pi as a tethering device

Connect the Type-C port on the Pi to your PC/Camera, it will automatically tether the internet over Speedify.

Windows requires an additional driver.

Identifying client using P2P or BitTorrent

Cannot connect to Wi-Fi 2.4Ghz client (Wireless WAN)

Check for connected USB 3.0+ devices as it's a common issue with 2.4Ghz Wi-Fi

Quick VLAN setup

Assuming ISP modem is plugged at trunk #1 on the managed switch:
Network -> Interfaces -> Devices -> Add device configuration

(change Device Name for a more friendly name to appear in Speedify UI)

Network -> Interfaces -> Add new interface

Set Firewall zone to RED, and gateway metric to 200 or more.

Reduce bufferbloat - Gaming (less bandwidth gain)

  • Set one WAN as "Primary", preferably the landline or the lowest latency, others as "Secondary".
  • Set transport mode to UDP, and rate limit each to 70% of max speed.
  • Optionally set mode to redundant.
  • Engarde may perform better than Speedify in this case but requires limiting the speed per WAN via SQM which may hinder throughput.

Ping (ICMP) is not a good measure, in "Streaming mode" detected flows are optimized and use a different path (redundant - low buffer). Use in-game latency indicators.
Speedify UDP mode is sensitive to software & hardware interrupts under load, requires a PC instead of Slate/Flint >30Mbit or Pi4 >80Mbit to control bufferbloat to a minimum (~10%)

Hide interface or WAN from Speedify

Rename interface to start with "br-"

Check downloaded image integrity

You can use in-browser tools to check the file for errors, the calculated sum is in sha256.* file in the Releases section. OpenWrt upgrade UI may also show you the sha256 checksum calculated after being received.
