Hi, thanks for posting question here.

To better understand your situation and locate the issue, may I confirm some information?

1.Who is your ISP and what is your network topology? Except tp-link router, do you have a modem or main modem router? What is the model of it?

2. Please follow the FAQ to check your TP-Link router's model、hardware version and firmware version, then share here.

3. Can you take a video to show how slow the web interface loads?

4.Did you get poor quality streaming on which device? Can you also share a piece of video?

Thanks for your cooperation.
