Here is a solution if TP-Link Router is not loading some particular websites

If you are having a problem loading or browsing a particular/specific website, then you can follow the steps below to resolve that problem.

Step 01: Navigate to your TP-Link router’s web interface. i.e. Normally http://192.168.0.1/

Step 02: Log in to your TP-Link router’s Administration Web Page

Step 03: Go to > Advance > Network > Internet > Click on Advanced Settings

Step 04: Now under ‘MTU Size’ change settings from 1480 to 1440

Step 05: Now Save Settings

Step 06: Now Shut down / Power Off the router, and after two to three minutes, Power On the Router

Step 07: Check if your website is loading after the router is connected to the internet. It should be working fine.

I hope this helps,

Thanks & Regards
