Hi guys.

First of all, my english is not my native language so maybe i won't be clear enough.

I own the ASUS RT-AC68U and have a 1GB fiber internet connection.
On my computer i have a NETGEAR A6210 wireless adapter (AC 1200) plugged on USB 3.0.
With latest driver installed.

Since a few days i have a strange behaviour with my router both in 2.4 and 5 Ghz:

On one hand with wifi i have slow file download speed (between 50to 80MB/s ) from http websites or my ftp.
On the other hand if i do a test on speedtest.net with wifi i have good bandiwtch, 320 Mbps download and 190 Mbps upload.
So i think my wifi bandwitch is fine.

Before posting i followed this guide :
https://www.snbforums.com/threads/guide-troubleshooting-wifi-issues.12825/
Especially the InSSIDer part.
As I live in a house i have very few other wifi netwotks around. I tried to change channels anyway but i have still the same wifi speed problems.
I also did a factory reset for settings, still the same problem.

If i try the same tests with the ethernet port i have no problem everything is fine.
So my ISP internet connection is not the problem.

On my SONY android tablet, with dual band AC wifi the same http or ftp test i have 200MB speed.
I plugged a usb hard drive to the router and download a file to my computer with wifi, i get 200MB speed.
So it seems the router is working fine for downloading files with wifi to my computer.

I updated my router to latest firmware two weeks ago (ver 3.0.0.4.380_7743). I was still using stock firmware, it was the first update.
I can't really tell if the problem came since this update or was already there before.
I only noticed the slow transfers on my computer this week end.

What do you think, why http or ftp speed is slow on my computer ?
Is there something i could check or change in the router settings with the latest firmware ?
Am i missing something obvious about file downloads ?

Thanks for your help to resolve this.

No replies to this so thought I would post for clarification... there is a difference between MB/s and Mbps.
1MB = 8Mb

Speedtest.net reports back in Mbps and your results are 320Mbps down and 190Mbps up.

You download a file that is reported in MB/s. Using the math, the 50MB/s * 8Mbps = 400Mbps. This also leads into write speeds of your devices vs just transfer speeds over the network.

But at first glance, it seems to me you are getting full throughput of your WiFi.

Now, I am not the smartest guy on this forum by many many miles, however I have been running 2 asus RT-68's in a base/repeater setup with stock firmware connected over 5ghz and my 4,000 sq ft home enjoys 100+Mbps property wide with no roaming issues for the last 24 months. (The property wide speed is why I am here actually but I will save that until I have exhausted searching what's been posted already in this forum.)

I had some growing pains learning WiFi but necessity is the mother of invention and with 5 iphones, 4 smart tv's, 3 ipads, 2 game consoles and a family with high expectations of their Dad, I had to pick up my game.

Hope this helps and I am here to learn even more.

I tried to set my signature but rules require me to wait to update that.
