There are currently 5 people in the household who are actively using the Internet / Wi-Fi.
At maximum times are 2 TVs, a PC, a Playstation and the router
2 - 3 cell phones still connected.
Most of the time Netflix is streamed on the televisions and games are played on the PC and Playstation.
How much bandwidth would my router need to supply everything with the Internet without any problems?
And would a second router make sense? Because we live in a big house.
The bandwidth itself is not the problem.
The problem is Wi-Fi.
The more participants you have, the more devices "radio" each other.
This causes great latencies and collisions.
Purely in terms of bandwidth, 100Mbit should easily be enough.
But try to connect as much as possible by cable.
Every device less in the WLAN helps.
TVs and Playsi are usually less moved.
If you e.g. Connected by cable, everything is less lame.
I have 10 passive devices in my WLAN and that's no problem at all. ^^
As long as there's no traffic, not.
As soon as all 10 devices start sending / receiving, you have 50 +% packet loss in the Wi-Fi
How high-performance your Wi-Fi is depends on the standard that your Wi-Fi router or access point allows. In the AC standard, for example, you theoretically have a maximum throughput of 1200MBit with maximum transmission power in your LAN.
Thanks to several antennas and networks in the 2.4 and 5 GHz range, the router can comfortably distribute the data packets to all connected devices. The better the router (Linksys, AVM Fritz, …), the faster it can do it. If the signal or the illumination is too weak, a repeater or an additional access point can help.
Behind this comes your access to the Internet. Here 50MBit should be the minimum for what you are describing. With 50MBit you can stream two full HD streams in parallel and still have some bandwidth left for surfing. More is always better, of course, but it is also a question of costs and technical availability.
When calculating your needs, it is not important how many devices you have in the WLAN or LAN, but rather what amounts of data these devices consume on average in parallel.
The best thing would be to buy a Wi-Fi amplifier to cover the whole house.
You won't get far without a 100K line.
You have no idea.
You can also connect 10 devices to your router. As long as he can handle all of this, that's not a problem.
So 12.5 MB / s corresponds to 100,000 Mbit / s (100K)
To gamble you need about 6 Mibt / s. Netflix uses 2.5 - 6 Mbit / s when the line is free.
(1 MB = 8 Mbit)

To gamble you need about 6 Mibt / s. Netflix uses 2.5 - 6 Mbit / s when the line is free.
Cell phones use significantly less as long as they are not streaming (YouTube, Netflix, etc.)
If the Ps4 downloads a game and only has 6 Mbit / s available, it downloads 1 MB per second. Games are usually very big. 10 GB - 100 GB. That's why it should be done at night, because otherwise you won't get very far anyway and the router only uses computing power and the line is completely blocked, which could be critical in the event of fluctuations.
(1 MB = 8 Mbit)
(1 GB = 1000 MB)
You can even connect 100 devices to one router.
That's not what it is about.
It is about the WLAN protocol IEEE 802.11.
Any device that wants to chat with the router blocks ALL other participants for a certain time.
Keyword CSMA / CA procedure and such.

If you don't have a plan of the matter, then don't talk in between.
What nonsense
Nonsense? I have explained to you the technical process of how these signals are transmitted (at least linked).
There's nothing to be said about that.
WLAN is a great technology, but for technical reasons it becomes slower as the number of participants increases.
Higher latencies and yes, complete timeouts and thus disconnections are definitely possible. Regardless of the connection speed!
Even with just one participant, packets can be partially or completely lost on the radio link.
As a rule of thumb, it is said that a WLAN connection is only around 70% as fast as an Ethernet cable.
