Archer C80 Very Low Wi-Fi Speed
Hi,
I'm getting around 900/1000 Mpbs up and down when I connect my Archer C80 via cable. But, when I connect it with Wi-Fi, regardless of 2.4GHz and 5GHz, my internet speed drops to 80-90 Mbps up and down.
How I can troubleshoot the issue? I've tested with my smartphone by putting it just next to router and again the speed is same.
It looks that something limits the speed at around 100 Mpbs but I couldn't figure out.
Best Regards.

Hi Joseph,
It is weird but I've fixed it somehow by disconnecting the cable from the modem and connecting again. I'm not sure what caused this but suddently speed is increased now.

Hello @XKSefa ，
Thanks for contacting our community.
Please check the link speed when you connect the clients to 5Ghz: How to check the associated/link speed on a wired client.
Here are some tips that might improve the speed of your Archer Router:
1) Disable QoS, please access http://tplinkwifi.net and go to Advanced >> QoS to disable it.
2) Disable Parental Control, please go to Advanced >> Parental Control to disable it.
3) 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.
4) Disable SIP ALG and UPNP: go to Advanced >> NAT Forwarding >> UPNP to disable UPNP; go to Advanced>> Security to disable SIP ALG.

Hi @XKSefa ,
I think you should continue to observe for a while; the network may be reestablished after reconnecting to the modem.
