some of the 2811 router would power off and can't power up

[rleung2001]

We have some 2811 routers in our remoted offices. There wasn't any power surge or outage, but the router has no light and no power. Pressed power switch, didn't turn on. I have to leave the power switch button to ON, then unplug the power cord from the router and reseat it.

It would work fine.

Has anyone experience this problem before?

looks to me is the loose fitting of power cable to the router. Once cable was reseated, router turned on.

This could be a cable issue as already mentioned. It could also be a marginal power supply problem. I've seen a problem like this on a PC recently and it turned out to be the power supply.

Just open the router and check the cables

and also tight the outer screw of power supply

your problem will get solve
