I have a Time Capsule in my upstairs office. It provides excellent coverage throughout the house, but I'm wanting to provide coverage to our patio. I placed an AirPort Extreme in the basement and wired it up via ethernet. I turned on WiFi and put the same SSID and password. (I initially tried the extend WiFi network option, but that caused errors.) Now I'm faced with a situation where when I'm on the main floor, WiFi devices will switch between the TC and AE. This causes momentary delays where it appears the internet drops. Is this a common thing when switching between access points? I thought the switches were supposed to be seamless. Not sure how to best configure my system. Ideally I would place the TC on the main floor, but that's not possible without dropping another ethernet drop.
