Setup:
Laptop 80.2.11ax
Server with 10GB NIC
10GB Switch

Issue:
File transfers from two laptops over wifi max at 27MB/S while the server is connected to the 10GB switch

This has been going on for quite some time but I've ignored it, especially noticeable when I'm performing file transfers from my laptop and streaming from plex and the streaming pauses and lowers resolution or stops.....

What I've tried:
Switching internal NIC cards in the laptops
Switching antennas
Different wifi routers
Transferring to a desktop instead of a server
Changing tunables on TrueNAS for cc_cubic_load and net.inet.tcp.cc.algorithm
Different Linux distros
No errors on the interfaces
Placed laptop next to router same limitation over wifi
/EDIT No diff between SMB or SSH.
None of these worked

What's worked:
Connecting the laptop via ethernet to the wifi router while the server is still plugged into the 10GB switch results in 100MB/s transfers (obviously this fluctuates)
Connecting the other NIC in the server to the wifi router results in 100MB/s transfers to the laptop over wifi. (obviously this fluctuates)

Theory:
The handoff inside the router from the wifi card to the internal switch (on three different 1GB switch wifi routers) has a bandwidth cap? Am I talking crazy?
Only thing left to try is wireshark.

For comparison with my 10GB Desktop to my 10GB switch I get 300MB/s+ when transferring a single file via ethernet 😀

Only thing left to try is mabye different SMB versions and wireshark.

I would start by running some iperf tests between the client and the server over WIFI to get a baseline of what you can expect over WIFI while eliminating other variables .

Also, are all MTU values set to 1500 ?
