My thoughts. If you have a mikrotik in the cloud, you can try a btest at a fixed send rate from the laptop to the cloud, and see if it seems to work ok, and to what speed. (If this works, maybe sort of hints at burstiness below) Perhaps the wifi for some reason is being bursty, and causing the internet output to overrun and drop packets while ramping up. Do you have a queue on your outbound interface? If so, is the bucket size small enough (0.01 maybe less) If not, perhaps try configuring one, (or shrinking the bucket size). Cake seems pretty easy and good. Conveniently interface queues work with fasttrack. (Though if you are marking packets you will likely need to add those marks to the queue) On Thu, 2025-12-11 at 01:13 +0000, Michael Junek wrote:
I've had issues on laptops before with receive side coalescing enabled. Disabling that (a PowerShell command on windows) significantly improved wifi performance.
This appears to have the relevant incantation for Windows: https://twobyte.blog/blog/2024-11-02_disable_rsc/ Having less luck finding the thing for Linux (which is showing the exact same symptoms). Would you expect this feature to be enabled for wifi and not enabled for wired? Because a wired connection has no trouble uploading at the maximum speed allowed by the plan. And just the name - "RECEIVE side coalescing" - suggests it would slow inbound traffic rather than outbound.
