The issues I had mirrored yours (I'm thinking back in 2019 though). One direction was rubbish, and it was localised to the driver/firmware for the wifi adapter. I thought it was upstream, maybe I am misremembering. But hopefully it's something similar in your case. -----Original Message----- From: Karl Auer via Public <public@talk.mikrotik.com.au> Sent: Thursday, 11 December 2025 13:50 To: MikroTik Australia Public List <public@talk.mikrotik.com.au> Cc: Karl Auer <kauer@nullarbor.com.au> Subject: [MT-AU Public] Re: Bandwidth oddity/problem 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.
