Update:

Internet still dropping off. Having to reboot router almost daily.

1. Replaced modem (no luck)
2. Had windstream replace line from house to the street (no luck)
3. Contacted Luxul and they have issued an RAM (waiting on replacement)

If replacing the router doesn't work then I will begin the process of pulling things off the network one by one to see if I can find the source of the problem.

Anyone have any experience using a NetGear DSL modem with the ABR-4400 on Windstream? Seams straightforward enough. I have the modem set to "Modem Only" and the router set to PPPoe followed by my login credentials for windstream.

Thanks in advance...
