I have an x55. With the latest firmware update, my network goes down when I reboot. I'll reboot the modem and the main Deco (by unplugging because it no longer shows in the app) sometimes it takes hours of multiple reboots for the network to show back up. This never happened before the latest firmware update? What gives? I'm about to contact tp-link and demand a upgrade for the main modem. Is anyone else having this issue since the firmware update?
