I'm at home with my parents over the weekend and over the holiday?

And therefore I took my ps4 with me to play online with my friends.

Now I've tested the Internet connection if that is enough or if I can only play solo at best.

So when downloading tells me the Ps4 system has it

15.5 Mbps

Upload 3.1Mbps

Is that enough to gamble with Gta5 online with my friends or does the internet go away quickly as we're still surfing with data volume?

That's not princely, but should be enough.

That's just fine. Normally you should have no problems with this internet speed. I have such a similar Internet speed at home between 12 and 20 Mbits per second download and upload between 1 MB and 3 MB per second. I have not had any problems so far.

How much data do you have?

To gamble online you do not need a fast line, because even 250kbit / s would be enough so 15.5 Mbit / s are more than enough.

Data volume varies from game to game, according to Reddit, that's 60 MB per hour. But that was only the value with 2 people in a lobby
