Connecting/loading issue

Hi,
I am running into this issue and are looking for a solution. When I connect to the internet website only "half" load ex. YouTube will show the front screen but not any videos.
When connecting via Lan everything seems normal as it just says "Connected' except things will not load properly, and with Wifi it says "Connected, no internet" and still has the issue stated above.
Everything seems ok on the admin page as it says internet Status: Good and it shows the attached devices.
P.s sorry if this was hard to read I had to write it on my phone.

Any ideas appreciated!
