My house has dead spots on WiFi no matter where I set up the access point that my ISP gave me. I turned off the WiFi functionality on the ISP's equipment, and set up a standalone 802.11ac router instead. Unfortunately, in this configuration, there are still parts of the house where I can't get a signal, or the bandwidth is very slow.
Can I set up the ISP AP and the standalone router on the same SSID to create an Extended Service Set (ESS) and have signal through the whole house, or will the NAT on the standalone router cause something to malfunction?
