PS4 disconnects to game servers and internet. Still connected to internet. System error? Fixable?

Question

This happened for the first time in Friday. I got my Destiny game and between 1-2 hours I get the message that I have lost connection to the game server. And bunch of others stuff saying I can't connect to the network and are unable to do network stuff with this account. Bunch in one. I tought that the internet was doing this, then I tought it was the game. But no.
Something is wrong with my ps4.
I played another game Final Fantasy XIV and the same stuff happens there too. I lose connection to the server.
But here's the actual problem.
I can't log back in to the game(any game that require net). Because it keeps telling me that I can't reach the server. And then it says that I must connect to the internet to view that and that. But that grey box that pops on the side does not show up and says that I have lost connection to the internet. So somehow I'm still connected but it says the opposite. I can already view my friends online. But I can't see their info because it loads forever.
I tried to go to PSN Store. But the only thing I can see is the blue background wave moving around and I can only click on "cancel" on my controller.
So I turn PS4 off. And it uses a very very long time on shutting down. And then it beeps two times as if it were forced to shut down.
But when I turn the console on again. Everything is fine. I can view my online friends and click on PSN store and go back to the game.
But in a short while, between 1-2 hours. Or 40 mins later. The same thing happens again. Wether I play Destiny or FFXIV. I disconnect to the game servers. I'm unable to log back in, and everything.
And this is totally ruining my gaming experience.
I even googled it and it seems like I'm the only PS4 owner who has this problem.
So this can't be the WiFi's fault because this is affecting the system of my PS4
A little info on my PS4:
I purchased it in Japan in late March.
Used it for 5 months soon.
Have always been carefully treated.
Never dropped it on the floor or gotten any swings.
It haven't always standed still because I pack it in the PS4 box when I'm moving it from my dorm room to my gaming room some times. I don't always move the PS4 every time I stop playing.
Previous experienced errors:
Flickering white screen on start up occationally. (Stopped after using a new TV)
Some times after starting up PS4. The sounds ingame are awfully loud and twisted. Must plug HDMI cable in and out or turn TV off and on to stop making these sounds (Happens anyway on any TV)
So. Is this actually fixable by patch or system restoration?
If it isn't, It means that I have to buy a new PS4.
And I refuse to buy a new Ps4, when I can play games normally but the system somewhat disconnects me from game servers and internet. I used a damn long time on saving money for buying this expensive machine and I won't do it again..
Is there ANYONE who has the same problem? Or am I really the only one who has this problem?

Hi i have had a similar problem fro about 8 months now, im with BT broadband, ive tried 2 different bt routers, a netgear and a asus router, all have the same problem, ive portforwarding, dmz everything,ive tried all the tests that can possibly be done to rule out that there is something wrong with my wiring in the house, my ps4 is connected via ethernet cable, and it is the only thing that disconnects from the internet, i even sent my ps4 to sony and they said they were having similar problems, and so they gave me a replacement one. What do you know i have the exact same problem with this one, i have literally done everything i can to try and fix this for 8 months and its still not working, please someone for the love of god help me. P.S before i got my ps4 i had my ps3 connected via ethernet to the broadband/ router i have now and had absolutely no problems.
