After the LAN network, the two-way (from and to) copying and the system version do not matter much, and the copy speeds are similar (108 and 116MB / s).
For the PCE-AC68 card, a new driver for Windows 10 ver. 7.35.351.0 Broadcom,
I reinstalled it from the CD version ver. 6.30.223.259 ASUS and the copy speed slightly increased from 55 to 61MB / s

sending remained unchanged

For Windows 7 on the driver ver. 6.30.223.259 ASUS and the last one I tracked ver. 7/12/39.28 Broadcom from the 2015 face.
copy and upload speeds differ significantly from Windows 10
copying

sending

To make the test transparent, I restored clean Systems from the backup and installed the PCE-AC68 drivers after the LAN update,
then I checked the impact of the antivirus and firewall on the transfer speed,
since in the previous test file transfer tests were performed with such programs.
For Windows 7, with the antivirus and firewall software turned on, copying and sending remains at the same level (they are even slightly higher by about 2-3MB / s),
and for windows 10, copying drops from 55-61 to 27 MB / s

and uploading drops from 38 to 10MB / s (maybe firewalls can't keep up with constant changes of Win10 compilation, because for Win7 it doesn't matter,
in order for the speed to return to normal, disabling the firewall will not do anything, you need to uncheck the coil in the Properties of the network card of the firewall program)

When I did these tests, the Compal modem was still working on IPv4 and was set in Modem mode,
PC approx. 6m away + one load-bearing wall

Wi-Fi 2.4 and 5GHz band in the location

Currently UPC has made a software change and installed the IPv6 protocol and in this version it is not possible (maybe for now) to set Compal
in modem mode, in order not to litter the band manually, you need to turn off the 2.4 and 5 GHz bands, but you cannot turn off UPC Wi-Free.
(this is such a curiosity, the consultant said that the guest network should be turned off, but this is turned off and UPC Wi-Free litter the 2.4 band with a strong signal)

Today I got to repair a laptop with Win7, 1Gb / s LAN network and SSD disk, after putting it on my feet I connected it to the ASUS router with a LAN cable,
and I ran a copy test, at the beginning two PCs via LAN cable (2x PC Win7, LAN 1Gb / s, SSD disks)
Win7 (test) ----- ASUS router ----- Win7
- Download rar file 3.5GB = 127MB / s (until I was rubbing my eyes)
- Upload = 115MB / s
then:
Win7 (Wi-Fi PCE-AC68, test) ----- ASUS router ----- Win7 (LAN)
- Download rar file 3,5GB = 94MB / s
- Upload = 54MB / s
