Very slow android transfer speeds on local network

Support Android

  1. There is a new version of syncthing (1.17.0). Might solve your problem once it is being built for F-Droid.

  2. Have you checked this forum post? Please help: How can I get speed higher than 2 MB/s There, a lot of factors are mentioned that might have an influence on slow transfer-speeds.

  3. Was your setup working properly once before? Since when has there been problems?

Does it work better if you turn on Global, NAT, Local announcing?

Unfortunately i am not qualified enough to know about why your device would show up as 3 different ports. I could imagine, since you hardcoded ip-adresses, you also might need to hardcode to listen on your android-devices ports? (See Firewall Setup — Syncthing v1 documentation for how to forward ports. If you could teach me port forwarding for Syncthing, in case you succeed, i would be delighted, because i tried it and failed xD)

  • Do you get a connection with TCP, Quick or via Relay?
  • Also, some specifics about your used hardware (especially the android-device) would be nice to have for a more in depths analysis to exclude hardware bottlenecks, like cpu/ram/wifi/networkcard limitations.
