Hello,

I have a strange issue with my Ax88u Merlin. When I run a speed test within the router itself, I achieve a full speed of 1 Gbps. However, over wifi, I only get a download speed of up to 300 Mbps, while the upload speed ranges between 800 and 900 Mbps.

I've tried everything and consulted various forums and topics, but I can't find the problem. I've also performed multiple resets, including a nuclear reset.

Could you please assist me further? I'm feeling quite desperate.
 
It sounds suspiciously like HW acceleration is disabled. What do you see at Tools - System Information > HW acceleration?

What firmware version are you using?
 
Yes, with Ethernet I am getting full speed.
Ah, OK. So this is a Wi-Fi-only problem. So probably nothing to do with hardware acceleration.

What link speeds are you getting for the client in System Log - Wireless Log ?
 
HW accelerationRunner: Enabled - Flow Cache: Enable

If you monitor that page, open another browser window and run a speed test what is the maximum RX Rate that you see?
 
Exactly what is happening here. running RT-AX86U_3004_388.4_0 My old plan was 300 i had for a couple of years.
My speed test in the speed test in AdaptiveQoS_InternetSpeed.asp. old plan 320mp DL , 38 UL and 250 DL on 5.0 and 2.4 140 DL - 34
I use Pixel 7. 2 weeks ago I upgraded to 1gb. Running the same speed test on my pc 847 dl and 41 UL.
My wifi numbers are have not changed.
 
I tried out the stock RT-AX86U_3.0.0.4_388_23285-g5068da5_pureubi.w. Nothing has changed. All numbers the same. I wonder how long fore more speed reduction? lol purchase date 07-2020.
 
I was speed testing on my pixel 7p. Foegot that I had a vpn connested. Disabled the VPN and got all ste speed was 900 from a 1 gig plan.
I ordered a replacement ASUS RT-AX86U Pro (AX5700). . I was telling my wife of this issue. What to do??
It arrives today.
 
Tell her the new router fixed it! 😁
