Nice to meet you!
I'm new to the forums so I hope I've followed the rules.
The wifi connection on my Lenovo laptop seems to be running at about half the speed expected. It's about 1 week old.
When copying large files (2-4 GB for example) I'm getting a sustained throughput of about 40-43 MB/sec but am expecting at least twice that rate.
I'm copying to/from a local NAS which has a gigabit LAN connection. I have two TP-Link routers in my home and getting the same speed via both.
On wifi connections from other devices I'm able to achieve 90+ MB/sec doing the same task. I've test 3 other devices/configs in my household.
I've test the Lenovo laptop/wifi card in question on a live session of Nobara and KDE Neon 6 and able to get sustained rates of 90-95 MB/sec.
Here in Mint the Adapter settings in the Network manager report Link Speed 1200 Mb/s and signal strength 'Excellent'.
Update Manager says system is up to date. Update Manager confirms I'm using kernel 6.5.0-26.
I manually updated to this latest kernel and I used the 'edge' edition to install Mint on this machine.
Driver Manager says No Drivers Needed.
Seeing in other posts that the following command (dmesg | grep iwlwifi) helped diagnose issues, I've run it and pasted the results below, hope it is of use :
