How to set up a network in the office?

Question

Network administration

There is such a network, all computers connect to one of the wifi, I want to combine 2 wifi networks into one and connect to the resulting network only through a computer with resources, and distribute the Internet from it to the rest through the switch, advise how to implement it.
Thanks in advance.
PS Please don't say that it's hard (this is idiocy, throw away phones and buy a 4g modem, etc.)

Answer 1

So many topics have been created, but there are no norms for an answer :(
I would advise you to do this thing:
1. Take a network cable for 8 cores
2. Put a jack on one side and plug it into a switch
3. On the other hand, divide the cable into 4 (2 cores per each side) and expose. It should look like this:
4. One side of the cable should be directed to one phone, and the other to the second.
5. 4 cores should be directed towards each phone (2 active and two passive for failover )
Thus, the second side of the cable will work in the "home antenna" mode.

Answer 2

It is impossible to combine two networks from different providers. You can only connect to both at the same time. But it will not be possible for the gateway to transmit simultaneously on both channels. Yes, let's say it will be possible to parallelize the transfer - mail there, Skype here. But at the same time, both channels can be used only for a very limited range of tasks - for example, download torrents.

Answer 3

Instead of question marks, put normal equipment, such as a router from MikroTik, and implement failover or Load Balancing, it all depends on the needs. Also, to combine two networks, configure routing, if necessary.
