So when someone from a telecommunications company called Globe asked us if we want to upgrade our internet connection, alongside with the upgrade, they gave out 2 Deco M5 models for free. When I used the first one, it is fine and helps me with my online classes. When we used the 2nd one after 3 weeks, the blinking stopped and I tried to use other wires to see if it will lit up but nothing happens. What can I do to fix it?
