Comment on I need help troubleshooting slow wireguard tunnel (VPS to home network)
stavefajl@feddit.dk 3 days ago
I am currently running mtr from multiple devices:
- in wireguard tunnel: single hop 10.1.1.1, loss% 0,1, avg ping 27.4 ms
- outside wg between same devices:
- ISP supplied modem/router 55% loss, avg ping 1.6 ms
- multiple hops without loss, avg ping 16-20 ms
- random intermediary 30 % loss, avg ping 20 ms
- endpoint, 5% loss, avg ping 25 ms
It looks like across the board my ISP modem / router is dropping 50-80 % of packets, and that packet loss is ramping up from 4% to 80 percent after a few minutes of running mtr.
It also looks like my VPS endpoint climbs to 20% packet loss over time (5-15 minutes of testing).
Can I use this information to probe further into the devices I have access to (ISP modem and VPS)?

Some devices will drop icmp packets. Does iperf show the same amount of loss?
Can you try a different internet connection such as mobile hotspot just to see if you have similar results? That could help identify it as a vps issue.

I had to borrow a phone to set up a mobile hotspot.
It has the same speeds inside the wireguard tunnel as when I tested from my wired connection (250 kbps TCP, 170 kbps UDP).
The loss reported by iperf is dependent on the bandwidth that i test with. But as I increase bandwidth from the client the loss grows towards 100%.
I tried testing in reverse (sending from VPS to devices on different networks) with surprising results:
