Single Deco goes solid red after power cycle and even on reboot
I have a single Deco X20 4G+ configured as 3/4G router which I planned to use as a mobile WLAN and Backup Internet connection.
It works just fine after initial setup.
Once I disconnect it from power, and power it on again its status LED turns to a solid red. The device is inaccessible.
Same effect after reboot via web UI.
Power cycling doesn't help - the device goes invariably into solid red mode.
The only remdy is a HW reset, and a complete new setup. This is not acceptable.
My attempt to upgrade the firmware leads nowhere since it claims to be up-to-date.
Is there a solution to this problem, or shall I return the device?
