Just did a clean install of Ubuntu 24.10 on my Lenovo laptop with an Intel AX210 WiFi 6E card.
I do a lot of local file transfers between my laptop and my NAS over WiFi and when I was using Windows, I’d get around 55-60 MB/s over SMB between my laptop and the NAS.
After switching to Ubuntu, transferring files over either SMB or NFS seem to max out at around 35 MB/s.
It doesn’t seem to be a limitation of the WiFi card, as iPerf tests show throughput to be just fine between other devices on my LAN, averaging around 70 MB/s.
Why do file transfers to/from my NAS specifically have such a drastic performance difference vs when I was on Windows?
For reference, I am using TP-Link EAP650 APs and my laptop is connected over 5GHz (WiFi 6) with a reported link rate of 1080 Mb/s and the tests were conducted about 6-7 ft away from the access point.
Any tips on how to troubleshoot this?
