Linux users with bad results might try:
`iw dev $interfacename set power_save off`
Linux on various laptops/kernel's has been known to be a little too aggressive with the power savings and it absolutely kills first ping latency.
(Although at first glance this thing might be fast enough not to notice).
- paulv 4y agoI discovered this issue on my rpi3 and rpi4s. There is always just enough latency when using ssh to drive me up a wall, but it went away when I tried to debug with ping. The first ping packet always took a bit longer than the others. I just assumed that was because of the arps, until I checked with tcpdump. Turning power_save off solved the problem immediately.
