Model: Archer C6  
Hardware Version: V4
Firmware Version: 1.13.6 Build 240430 Rel.54880n(5553)

I am not getting gigabit speed on my router. 

I have tried checking the wires with my jio router and they work at gigabit speed. But when i use archer c6 router in between , the speed are capped to 100 mbps on all lan ports. 

 

I have tried changing the speed negotiation settings but no change

 

Please help

 Hi @Abhinandan ,

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. To verify wired(Ethernet) speed of your Router, please connect the PC directly into the LAN ports of the Router, make sure all Ethernet cables are CAT5E and above.
3. When testing with wireless, please connect your phone/laptop to the high speed network (5G/6G) instead of 2.4G. In order to reach maximum throughput over wireless, put the phone/Laptop next to the Router.

 

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.
