My TTIG that’s been running flawlessly for 3 years, failed to reconnect to my router after a power failure. It just blinks green off and on about once a second. In my console, I see that it is disconnected. The device resets and enters setup as you’d expect. In setup it transmits an SSID properly. However, the wireless password on the label no longer allows me to connect. Would you recommend any other troubleshooting other than just buy a new one?
