so we have this problem that whenever we use the LAN cables that the wifi in the entire house goes down, we use 3 routers one in the main room to connect to the wall, the other in the living room for the TV and HIFI and one in my room to connect the PC's, we think its the 2nd or 3rd router thats clashing with one another and that causes the wifi to stop working, the wifi works fine when we turn off the 2nd and 3rd router, is there any solution to this? a way to keep using 3 routers and keep the wifi enabled?

we use a password from the phones, and if we hook the PC's with the cable then the wifi automatically turns off. as if the main router isnt givin wifi signals anymore

Make sure the DHCP is turned off on routers 2 and 3. Also make sure to give them static IP addresses outside the DHCP range given by router 1.

Example:

If router 1 DHCP range is 192.168.X.2 to 50, you should give router 2 192.168.X.51 and router 3 192.168.X.52 (or any numbers above 50).

im unsure of how to answer what kind they are, and we just connect them with ethernet cables. so 3 routhers and 2 dedicated ethernet cables leading from router 1->2 and 2->3, leaving 3 ports open on each router that we use to connect devices.

Sounds like an IP conflict to me? The solution is to make sure there is one and only one DHCP server in operation. It should be on the router that is actual used to connect to the internet. The other "routers" need to be set to act as access points and can either have a static IP outside the DHCP assigned range (highly preferred) or get an IP from the actual router.
