Connecting multiple routers

[audaciousgoat]

Hi. I have an issue with my internet and can't solve it. I have an ASUS N66u router. From there, I'm running an ethernet cable through the house to another router, a nice TP-LINK Archer C5 AC1200 . With this setup, both emit a wireless signal and can be hardwired to with a computer or TV. However, if I add another router, stuff starts getting funky.
I have a medialink router that I have connecting to the second router through ethernet. When I connect this third router, it simply says no internet access. I can connect to any of the routers while hardwired, but I cannot get outside access.
I noticed when connected to the medialink via ethernet, the etherent ports are blinking either quickly or slowly. I have tested all my cables and they are fine, I have also tried turning off the DCHP server. Anyone have any idea on how to fix this problem? I've been trying to fix it for a week and cannot find a viable solution.

The secondary routers need to be configured as access points (depends on the model and firmware if this is possible). Quite simply, you have multiple routers battling it out which has control of you home network.
