I am trying to find a single high power wireless N router that preferably has a Guest network feature. My client has a very large home, and there is simply no way to centralize the location of the main wireless router he currently has. He currently has a range extender type of device for the far side of his house, but that creates a second wireless network and for some reason, it needs to be rebooted and/or reconfigured at least once a week because it just stops working. I was reading about some high powered wireless routers on Amazon and other such places, but none of them seemed to have the guest network feature. Is the guest network feature a rare thing among routers? His main Netgear N router almost reaches to the far end of the house, but the signal strength is very low and un-reliable on the far side of the house.
Thanks for any advice.
