Model: Archer AX11000  
Hardware Version: V1
Firmware Version: 20230906 rel.74809(4555)

Hi, 

 

 

Connected various ethernet devices to my AX11000 and (according to Task Manager) they are getting throttled at 100Mbps and I was wondering how 

I increase this speed.  A two week old Windows 11 shows 100Mbps.  I have tried the following: 

 

Direct cable connection to the wall socket in my home-office, therefore cutting out the switch.  

Tried a few different cables. 

 

I don't have a cable long enough (yet) to test this PC direct into the router so I dug out a 5 year old Dell Laptop abd wired it straight into the router. - 500Kbps. 

 

Also tried an MS Surface laptop but that was via the MS dock, that might be throttled I'm sure. 

 

The router shows 1000Mbps on all ports.  

 

I really don't know what else to try. 

 

Anyone got any suggestions? 

 

Thanks

Hi@davegray,

Thank you for reporting your issue to our community.

Please make sure all Ethernet cables are CAT5E and above.
Here are some tips which 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 best one for 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.
