Need Help Optimizing Home Network

Hello everyone. I have fast access DSL from AT&T and since December we have been having terrible intermittent issues in our area. Unfortunately U-Verse isn't offered yet where I live so we're stuck with the premium DSL. However, before December we were having no problems whatsoever. What happens is when multiple devices use our Internet in our house, we will get very frequent 2-5 second drops. After the drop our connection will reconnect very quickly and we usually won't even notice any lights on our modem turn red. Every now and then the Broadband and Service lights will go red until it reconnects again. Whenever we have a drop, all devices in the house are disconnected, so surely it isn't any of our devices causing these outages.

AT&T has sent several technicians out and all have verified that our line is sound and they rebuilt our NID outside and even rewired our ground wires. We have rewired everything on the inside too, just in case that was causing the problems. Today a tech at AT&T told me that it's possible that my network settings in my router are not properly set up. I'm fairly tech savvy but networking isn't my speciality so I'm asking just what our optimal settings should be on our router.

We use a Netgear 7550 which is a router and dsl modem all in one. We have the most current version (that the interface claims anyway) and have 4 hardwired devices in our home and one wireless device that we use the internet for. I have included a screenshot of our current set up with the sensitive information colored out. Particularly I need to know if VC-Mux or LLC ATM Encapsulation is what we should use. Along with what we should be using for VCI, VPI, and PPPoA/PPPoE should be used. I also don't know much about DHCP leases so if you see anything out of line in the screenshot, please help me out with information. Thanks so much for the help.

I can't load your pic from work but I can tell you that standards that you listed are types of authentications. Such as PPPoe, you could say its a way for your router to "log in" to your service with a username and password. Whichever one you are using currently, if it is working then that's the one that you should be using for att. Where I live AT&T has us on a PPPoe service.

DHCP is dynamic host configuration protocol. Its a way of assigning IP addresses to devices dynamically. Generally some routers have this set to 24 hours but for a home you can really set it to whatever you like. It just means that a device with have lease on a particular ip address for 24 before the router will check back in and ask the device if it still needs that address.

This doesn't solve your problem obviously but it should give you more insight on what you're looking at.

Thanks so much for the info. An AT&T rep has been assigned to our case so I believe the solution is close to being found.
