We are currently running Comcast internet and phone through a Netgear Wireless-N 300 Router and an Arris TM502G Modem. Our phone service works fine, but the "Link" light isn't showing up for...


There's a reset button on the back of the modem. It'll power cycle it. That should work and if it doesn't make sure everything is connected and tightened.

How to connect netgear fs108 to cable modem


leeb..... switches cannot be connected to the Cable modem.... because NAT will not be enabled in cable modem....so there wont be any DHCP server present in the cable modem....
Nat will be enabled only in DSL modem like AT&T verizon etc....So DHCP server will be present inside DSL modem...that is the reason why switches can be connected only to the DSL modem....
With NAT enabled modem, switch will work as a switch.... With NAT disabled modem, switch will work as a hub.... This is the difference....
Any doubts further ? please clarify with me.... I am ready to help you....

ARRIS Modem + D-Link router = no internet


when you are on Cable Internet with a "modem" only connected directly to the computer, what the ISP see is the computer's MAC Address (command prompt -> type ipconfig and hit enter).

put a router (which has it's own MAC Address) in-between and the ISP wont let you cause it sees the router not the computer.

check physical connection: cable modem -> router -> computer(hard wire for this troubleshooting)

access the d-link gui and locate the “Clone MAC Address" button (supposed to clone the computers MAC Address - verify if it's the same), save settings & reboot the router.

I cant get out to the internet when I connect the netgear router.


Be sure that your cable company has enabled your internet. Power down the cable modem, power down any routers and computers. Start cable modem first, after internet connectivity is indicated, power up the router (if you have one) and then power upi the pc

Connecting my arris modem to x-box live


I have an Arris cable modem and use Xbox live. They work very well together. Most ISP's will only allow one active device at a time. When you switch between you cable modem and your Xbox you need to use a pen and press the reset button on the arris every single time you switch.

WGR614-netgear-54 mbps-Plus wireless plug=in


Only real trouble shooting I can suggest is power cycle the modem and router. If you have the Comcast Digital Voice modem make sure you push the reset button on the back as there is a battery in the unit and unplugging won't do anything.
