Wifi doesn't work in my phone

[Rodrigo 1]

When I use any social media the wifi in my phone doesn't work fine, for example in twitter, I can see all the tweets but I cant see all the photos and videos, same in WhatsApp. But when I use cellular data or another network, everything is fine.
I was thinking about changing the channel of my rooter but I don't know if this will work
Can someone help me please?

Welcome to Android Central! Does this happen on any wi-fi network, or just your home network?

Sounds more like an encryption problem, Check the router (connect to it) and see if WiFi encryption is set to TKIP or TKIP+AES. If it is, change it to AES. (My wife could never see a video on Facebook and it took minutes for a picture to appear as she scrolled. The ISP had their router set to TKIP+AES. Since it takes something a lot faster than a PC to break AES, I'm not worried. Some genius at the ISP decided to turn on as much encryption as was available. The PCs and laptops handled it fine, the phones wouldn't.)
