Very bad WLAN performance

What speed do you see when using robocopy from the Win 10 command line?

Around 45mbit. About same thing when I copy in the explorer, 5-6MB/s.

In the Firewall I still see 144Mbit (last transfer speed, which is wrong).

And in Windows, Wi-Fi Status, Speed: going from 85 and 130 Mbit, up and down. (however, I am not transferring anything, not sure if this should read 0 when not doing anything, like task manager does)

Signal Quality: full.

Access Point is about 3m away.

Are you sure that that traffic isn't being slowed by Intrusion Prevention?

Turned off IPS, and all the options under other tabs, same result.

Any ideas?

What if you try connecting the AP to a different NIC?  Make & model of NICs?

That values sounds for a n connection reasonable. A good read to phy (connection rate) vs. real transfer rate (data throughput)

5-6 MB/s is a good value for a realworld n connection.

WIFI is a) a halfduplex connection and b) over a shared media (air) with c) depending on mcs and error correction noteworthy overhead.

Over the day throughput may be even lower, at 3 a.m. when air is really quiet it might go up to 8..10 MBytes/s in best case.

Remember the old 10 HDX coax cabling? The more clients were talking, the slower single client throughput became....*sigh*, good old times ;o) Shared media access...
