My apps are not responding and neither is my internet

gee did it ever work before or just found a used ROKU in a garage sale>?
NO system stated, at all, what do you have connected before you, (endless possible for sure)
so I will do wild guessing,
I first guess you have old TV that is not SMART, so no Netflix player s there.
so you buy a ROKU, (I have 2 love them, more on that later)
is this a new RUKU or old.? if old you need to upgrade the firmware on it per your manual,
The ROKU news version self upgrade them selves and also upgrade app players all the time, so that new feature work, using say the * star button,(settings for many things)
min upgrades as I sleep, ROKU is the best there is, so good it is installed inside newer TVs now, yah it works that good.
NOT TV made works that good unless it has ROKU in it, OK???
see why, (answer the new apps update all the time, endless)

what does not respond mean
does the RUKU player work , on the main right side screen of ROKU, and MUST work on their web player channel this would be first test, not Netflix using logic of walk first then run.

Then see of you internet connections work. If the ROKU channel is dead, internet is next , mine has wifi and ethernet channels.
I use the latter, and NEVER FAILS, and we all know wifi is PITA.
(of 1000 reasons)
But you have wifi , I bet and that is a pain, if to far or too slow or the wifi channels are all overloaded by others in home or close neighbors (so move to higher wifi channels)>?

Tell again what "NO RESPONSE MEANS"
elaborate on just that,
1: the menus are missing , black screened?
2: what does not respond, exactly, what.?

on mine I use PLEX and I click PLEX and my PLEX server comes up. wow PLEX.
there are like 100s of APP players there are all dead/?

Try going into settings/ apps, locate Facebook and clear the cache. if this doesn't resolve your problem, check to see that the app is up to date, if it is, then try uninstalling and re-installing the app.

You might have too many apps or you might have too many apps that are active in the background that are slowing your tablet down. Uninstall unused apps or turn them off through settings. Apps always sync in the background, even when you don't use them. When too many apps are running at the same time, they drag down the wifi speed. Go to Settings>Wireless and Networks> Data Usage, view all the apps that are actively syncing. Also, in Settings>Device>Battery, you'll see which apps are actively draining your battery (if this is also an issue). You might be surprised which apps are either draining your battery or always syncing.

You will need Phone and Internet Service

you might have transfered it to lacal sd card which are transfered to some other location
from file manager look wether all files are there only where it was prior(since app follow the same pathway to load app)
try to relocate it on prior position
or else you have to reinstall them
remember alway keep your backups

I'm not completely sure about what you said, but if you are having problems getting on your iPod to browse Internet/email etc.? You do not need a server (e.g. Cell phone type) to get online but you do for the Internet. That should be who ever you have your wifi under, for ex. AT&T Sprint or similar. Go to your Settings icon, then tap wifi and make sure that your wifi name is listed (whatever name you gave it when it was set up). Also make sure that your password is correct. Most wifi's even some Hot Spots will require a password, the hot spot should say what the general PW is. If those are set a d working you shouldn't have any problem either browsing or checking email. If you have more specific question than please post, without YouTube. If you are using another device to record the YouTube video then check those settings on that device to check your iPod.
