I bought my router used off of Amazon. When I tried to use it, my internet connection wouldn't work. Without it being connected to the modem, when I plug in my router the power will blink green and then become solid. The Internet LED will then turn on to a blinking orange, solid orange, and then green. The router will then shut off and restart. I have been able to connect to the internet a few times when there's a time lapse between the router restarting and both lights being solid green.
I've tried resetting it, doing a 30/30/30 reset and moving it away from my modem by 3 feet. I'm pretty sure it's a hardware issue, but could use some experienced feed back
