stable router?

Question

Iron

The office has 10 computers and 20 laptops + about 10-15 smartphones. Everything works through wifi.
Installed 3 routers interconnected. As a result, the Internet drops 2-5 times a day, depending on luck and how someone uses the Internet.
As a result, every couple of hours someone screams at the whole office about the Internet not working.
Stationary computers we think to connect wires. Over the next couple of months, 5-10 computers will be added.
Hence the question. How to build a network so that the Internet does not fall? Which router to buy?

Answer 1

Take a set of three points www.ubnt.com/unifi/unifi-ap and a router for them in the set www.ubnt.com/edgemax/edgerouter-lite or www.ubnt.com/edgemax/edgerouter-poe then you can not install injectors PoE

Answer 2

Or the same Mikrotik

Answer 3

What is the problem - to stretch the wires to computers and laptops? And they will be happy - non-falling Internet.
And the remaining smarts will have enough existing routers.
WiFi is not a business solution, but an eternal headache for the admin.

Answer 4

ithappens.me/story/13057 here's some information for you to think about ;)
By subject - transfer everyone you can to the wires.
From the points - watch Ubiquility top-end with "civilian" antennas or AP cissies (40 thousand each with a new rate). The rest is slag and is designed for 3-4 clients with comfort, if there are no other networks nearby.

Answer 5

Is there a pattern to this event?
Ask everyone to turn off and connect in turn.
I have a suspicion that someone has a device with an old one and it switches the router to it.
Or look at the standard before and after the fall of the Internet.
