Model: Archer VR600  
Hardware Version: V3
Firmware Version: 1.5.0 0.9.1 v009e.0 Build 220518 Rel.43816n

Hello

I have a vr600 v3 ac2100 and I did not really use the wifi 5 feature but now I install a nas server at home and the copy over wifi 5 is very slow (9 to 12 MBytes/s ) and a I have tried many configurations (copy between two phones , between two laptops ....) and the result is the same but over wired connection the speedrate is about 60  Mbytes/s and I try a freind access point from another brand and  the copy was about 70 MBytes/S over wifi 5 and 100 MBytes over wired connection 

 

Is there any configuartion that can speed up the wifi in 5 Ghz

 

Disclaimer

I connected all the devices in wifi 5 AC (5 GHZ) network of the vr 600 router

I check the acess control option and it was disabled 

 

Thank you for your Help

Make sure that QoS is not enabled on the VR600.

You can try setting channel width to 80Mhz for 5GHz band and test if that makes any difference:

This could happen when NAS connected to your VR600 negotiated 100mbps ethernet speed. Check this here:

 

If that's the case change the VR600 port and if it persists use another ethernet cable marked CAT5e ot CAT6.

The theoretical bandwidth maximum can be achieved by selecting wireless channel 36 and channel bandwidth 80Mhz:

 

If you have any issues on wireless channel 36 set it back to Auto.
