Verizon FIOS G3100 router

If you're looking to upgrade the power supply, it's the green one in this link.

Amazon.com: FAMKIT Mintata2019 8-in-1 Universal DC Plugs 5.5mm x 2.1mm Female to Male Power Supply Adapter Jack Connector Tips for Laptop : Electronics

Thank you! I'll give this kit a try. Have you added a power supply to your Fios Router?

I tried the green tip but power does not pass through. Back to Verizon fios G3100 power supply & router lights right up. Router input is center + and outer -.

Should the DC adapter plug be rated same as device?For example, Verizon fios G3100 is 12v 3.5a. Now back to the size of that plug?

Anybody know? Thanks
