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
