I have a main router in aimesh mode dual band feeding internet to 2 routers down the property using a powerline adapter (can't use moca). One of those routers feeds net to a wireless router furthest down the property on a seperate powergrid. Which router it is switches depending on if the other drops. Like a backup. They are in 2 seperate cabins. Problem is that I notice that the 2 wired routers down the property will fight each other over what device connects. Sometimes even a binded device will no longer connect like the band is being drowned out. My question is, if I disable both bands on one of those routers, will it still be able to be a backup for my wireless router? Give it internet? Or should I just unbind everything, and enable only the 5 on my one and 2.4 on the other. Would the wireless router still be able to broadcast dualband if its receiving signal from just a single band? The binded devices are 4 TVs 5 band and a camera 2 band. The binded devices on my main never have a problem. The routers are the 68u series. Thanks.
