2wire 1701HG
It's a wireless gateway for DSL. A friend brought it for testing.
It's a real light show. It starts out doing nothing. After two minutes it starts flashing its three LEDs. very short pulses that start out about 2 times per second and gradually (1 min.) go to 10-20 Hz. This keeps up for a minute or two and the flashes go from 5% duty cycle to about 90%. Another minute and it starts cycling, 2 times per second the Power LED goes red for 1/10 second and then it turns green while the other two LEDs light 4/10 second. This keeps up for five minutes or thereabouts. Then it starts going "power red" 1/3 second and "power green" plus the other LEDs 2/3 second, keeps that up for five or ten minutes, then we get 1/3 second power-green plus 2 others, 1/3 power-green only, 1/3 second power-red; that kept up for over an hour. An earlier test had its final stage different; the power light would blink green once per second, 32 times, then there'd be power-red plus two other LEDs and a click for half a second. The DSL provider suggested it might be power supply. It's rated 5.1V 2A and shows 5.3V no load. With this kind of pseudorandom behavior I'm thinking hardware failure, but wanted to check first to see if anyone else has seen anything like this. -- Happy Birthday, Canada!
