Okay, I've been just using Deco E4 for 2 weeks and then suddenly while I'm playing games online and just leaving the Mesh alone, suddenly, the connection missing and when i look at the Mesh suddenly the LED is yellow not white like it used to, I've been trying to fix by rebooting it, reset it, even trying reinstall the Firmware from V1 to V4 again, I'm kinda frustrated by it it because I've been waiting for whole night just the LED hoping turning to Blue. I wanna help to prevent this, because it's very annoying bug that nobody talks about much other then fixing by resetting the firmware, any expert or working with the TP-link knows what cause this? I'm writing and joining community because i am frustrated.
