Unable to play YouTube videos over Wi-Fi.

Hi,

My phone is unable play YouTube videos from any browser when I'm using Wi-Fi but it works fine when I use mobile data.

Please help me out here.

Note: There's no issue with the speed of my Wi-Fi connection. The issue is only with the YouTube videos and only with my cell phone.

 

Problem with the Wi-Fi in application 'YouTube Downloader'

Do not you understand?

The problem is I can not watch videos when I connect to the Wi-Fi if I have the data package off.



Do these steps:

1: Put your phone in offline mode.

2: Active Wi-Fi and connect to a wireless network.

3: Start the application 'YouTube Downloader' and try to play a video.

Can you play or not?

 

Slow Wi Fi speed

I have Windows 10 on my DELL Inspiron 2020 PC. When connected to the router using the LAN cable I get very good download speed. However when I connect using Wi Fi the speed is very slow.

My drivers are updated.

What should I do ?
