Hello,
Sorry to hear the speed is not as good as expected, please help verify some details and we will try to fix it together:
1. What is the actual speed you get from your ISP and what is that speed when you connect a computer to the ISP modem directly? What is the speed when connected one computer to this AD7200?
2. How did you test this speed via the router? Did you disconnect all the other devices from it and only leave one computer performing the test? How about the wired/wireless negotiation speed on that computer? Please verify it by referring to the instruction: https://www.tp-link.com/support/faq/2265/
Note: For wired negotiation speed, it is the same; while you need right click on local area connection or ethernet.
3. Besides, you can refer to the instruction below to narrow down the issue.
What should I do if internet speed is slow when the device is connected to the TP-Link router?
4. You may also try to change the DNS server to a third-party one on this AD7200 if it is your main router, such as Google's DNS server 8.8.8.8 and 8.8.4.4, then monitor again.
Thanks in advance, and have a nice day.
