Bests & Worsts Reviews from Amazon

The Echo worked fine for a year and three months and then it failed to connect to the internet. Resetting it to factory defaults and going through setup didn't work. Running lower levels of security on wireless (even none as a test) didn't work. I spent some time with 1st level tech support and a little more with 2nd level tech support but still have no idea what the problem is. There's a phase in setup where the user's cell phone, the Echo and the access point are supposed to work together to complete setup. It gets stuck in this nebulous phase repeatedly. Echo failed to connect with the following routers: ASUS RT-AC88U, 3.0.0.4.380_1354 firmware, WPA2-Personal, AES ASUS RT-AC66U, 3.0.0.4.378_9533 firmware, WPA2-Personal, AES also tried WPA-Auto-Personal, AES Cisco/Linksys WRT610N-V1, running DD-WRT v24-sp2 build18946M, BG-Mixed mode, WPA-Personal, AES All attempts were made using the 2.4GHz band. Laptops, phones, tablets and printers connected to these routers without issue. Echo is a good idea and is useful when it works. When it fails I'm surprised at how difficult it is to determine why.
