Have a D-Link DSL-520B modem Can i use this one in place of the Motorola DSL Modem?

If you have the older AT&T ADSL, then yes, you can usually use whatever modem you want as long as either it or the router behind it is configured correctly.

If you have ADSL2+ or VDSL (both of which are branded as U-Verse), then no, you must use AT&T's modem.

first, thank you for your quick and knowledgeable response, I was told that the modem is first-generation. How can I tell exactly what kind of modem it is. It gives me a model "Motorola 2210-02-1ATT " and style: "MIPDSLA".

if this is not an adequate description please tell me what information you need and where I can find.

I contacted D-Link and they said the modem was defective. They told me to take it back to the store and exchange it. When I was done and  came home with the new D-Link and it did the same exact thing.

The reason I'm changing it is because I ordered the high-speed connection and it was checked at the line at 11 megabits. but on my computer screen the Max that I've seen is 1.4 Mb. Is this what I should expect no matter what modem I use?

The Motorola 2210 is an ADSL2+ modem for U-Verse IPDSLAM connections. It is required by AT&T that you use the Motorola modem, you will not be able to use the D-Link.

The line rate and the rate you see on the computer screen are in different units.  The line is in megabits (Mb), while the computer displays downlaod speeds in megabytes (MB).  They will differ by a factor of 8.

11 Mbps is approximately 1.4 MBps.
