Hi I have a problem, several weeks ago I noticed a problem watching videos on YouTube. I have a 1gb connection and I didn't have this kind of problem. I have also noticed that when downloading or updating applications in the Google play store it does not download and I have to switch to mobile data to be able to download without problem. 

I have already restarted the devices, I have also left them to their factory state and I have even created a new network and I continue to have this problem. 

Someone who has any suggestions about it. I'll be grateful.
