Model: Archer AX3000  
Hardware Version: V1
Firmware Version: 1.06

FYI the hardware version on the unit's sticker is 1.6, not V1

 

I'm seeing huge discrepancies between my wired and wi-fi speeds.  My desktop is a wired conection with a Cat 5e cable and I see peak speeds of 600Mbps using Ookla.  Running the same test with my 2 laptops, my current and previous phone and my tabledt, I typically see 150Mbps.  Occastionaly 180Mbps but never faster and regardless if I'm 6 feet away in the same room or somewhere els in my house.

 

Rebooting it doesn't change the performance.

 

It doesn't seem to be an issue with memory or CPU, they show in the 20s. I tried tweaking QOS for various devices wihout seeing any change.

 

Other settings of interest

Running in ROUTER mode

WPA2-PSK with AES encryption

Transmit power HIGH

OFDMA is ON

No VPN server

No Alexa

SPI firewall ON

DoS protection OFF

Guest Network OFF

2.4 and 5 GHz are the same SSID

 

Any suggestions welcome

Hello @GoldRiverBob ,

Welcome to our community.

 

If you are experiencing slow Internet speed with your TP-Link Archer Router, here are some steps to help troubleshoot the issue:
1. Please use https://www.speedtest.net  or the speedtest APP/CLI(https://www.speedtest.net/apps) for testing speed accurately.
2. Please make sure the speed of your ISP/Modem is good by connecting a PC directly into the ISP Modem/Router.
3. To verify the wired(Ethernet) speed of your Router, please connect the PC directly into the LAN ports of the Router, making sure all Ethernet cables are CAT5E and above.
4. When testing with wireless, please connect your phone/laptop to the high-speed network (5G/6G) instead of 2.4G. To achieve maximum throughput over wireless, place the phone/Laptop next to the Router.


Here are some tips that might improve the speed of your Archer Router:
    1) If Ethernet speed is slower than expected, please try different Ethernet cables (CAT5E or above) on the Router.
    2) Disable QoS, please access http://tplinkwifi.net and go to Advanced >> QoS to disable it.    
    3) Disable Parental Control. Please go to Advanced >> Parental Control to disable it.
    4) If wireless speed is slower than expected, please go to Advanced >> Wireless Settings to change the 5GHz Wi-Fi channel. You may try different channels to find the one that best suits your environment.
    5) Disable SIP ALG and UPNP, please go to Advanced >> NAT Forwarding >> UPNP to disable UPNP, go to Advance >> Security to disable SIP ALG.
    6) Try a few other speedtest servers, other servers might reach better speeds.

  @Joseph-TP 

I turned off QOS and diabled SIP ALG and UPNP. The Wi-Fi speed has improved dramatically 2-3x. 

 

THANKS!!!!

 

I'm going to re-enable them one at a time (QoS first because I think I want that enabled) and see what happens.
