I have a problem with my internet ( is this the right category?)

[TRBAsado]

I have a problem with my internet and it does not work I think it could be a problem with how many Devices I have connected I have a router that has a switch that has 3 computers on and the second wire is for my other switch which is for the lower floor which has 2 wifi router things and a smart tv and a osn receiver
And the problem is when ever I try to use one of my computers the internet does work but it sometimes just stops working and whenever my computers have a working connection my switch for the lower floor doesn't work which mean also the tv and receiver and the 2 wifi routers don't work and it just keeps switching between the 2 and when I disconnect the wire that connects to the switch for the lower floor the internet works perfectly on my computers and ideas on how to fix this ?

Make sure the DHCP server is disabled on the extra 2 WiFi routers. There should only be one DHCP server on a network, and it's usually on the router which is directly connected to the Internet.

Having multiple DHCP servers can cause exactly those symptoms.
