Ps4 internet?

I have a problem

So we have 2 Playstation at home. In one, everything works perfectly with the wlan and my when I log in my ps4 I have only perfect wlan then 1 min later no longer wlan then 1min later perfect wlan then no longer Sometimes I have when I'm in ps4 menu is perfect wlan then I start a game and I have no Wi-Fi anymore.

What should I do

I know. I just think of a weak line. Do you use a LAN cable on the Ps4 or do you do it over a normal connection? Recommend you a LAN cable. Otherwise, you can sometimes rebuild the database maybe that brings something. If not only helps another contract with stronger Internet.Oder you play only when no one else is on the Internet.

But my data stays on the ps4 when I rebuild the databases or

Yes with me and a friend of mine, nothing happened. The whole takes only 1-2 minutes.

But I have only had this problem for 2 weeks before everything went perfectly

If your Internet contract has not changed, it is certainly on the Ps4 itself. Eventually something is broken. But I have no idea. Maybe you just call times at the PlayStation Support and Schilderst your Problem.Die probably know more.

Okay thanks
