FINALLY my U-Verse service is stable, here was the shit to get it to work properly...
FIRST, my package is as follows:
- U-450 HD TV Service to 7 TV's
- 24Mbps/3Mbps Internet
- One Voice Line
My U-Verse service has been on the fritz ever since it was installed in 2010. First it was required to have the entire house rewired for CAT5e ethernet in place of the RG6 Coax originally installed way back...Apparently the homePNA COAX connection isn't ideal for U-Verse service. TV signal pixelated CONSTANTLY using the COAX. SO I demanded that AT&T rewire each room for a CAT5e jack in place of the COAX. It was good timing too because we resided the house and were able to run the ethernet cabling behind the new siding, making a much easier install for the U-Verse tech. The rewiring did the trick, so there was not a problem with the copper between the VRAD and our NID. The line loop length is approximately 1000 feet.
Here is a screenshot of my line stats (after new install of CAT5e and new 3801 gateway):

And as you can see we get the advertised speeds, only using a wired connection. WiFi on both the 3800 and 3801 is sluggish, even with full signal srength. Speed test image below:

NOW some more technical stuff, but very interesting none-the-less. Since the bitloading graph below is a graphical representation of the frequency range (horizontal axis) in Mhz that my line is capable of and using, while the bitload is on the vertical axis. Essentially the graph is showing how many bits are fitting in each bin and at what frequencies the bins are spread out across the line. The better the line the more bits and the more bins you have that can be used - thus the higher bitrate.

In terms of profiles used by AT&T, I am using the "G.993.2_8d" protocol, or better known as "VDSL2" using profile "8d". Here is a table of profile designations used in VDSL deployment.
[att=4]
AS you can see, if you compare the bitloading graph in this post, profile "8d" uses up to 8.832 Mhz, as can be seen to the right of the bitloading graph, where my line uses up to approximately ~8.8 Mhz. AT ~8.8 Mhz my line is capable of holding 5 bits/bin. As you drop in frequency (as in using frquencies below 8.8 Mhz) the more capable the line is of holding more bits per bin. The better the line the more bits and the more bins you have that can be used - thus the higher bitrate. As you can see, my line is nearly perfect.
So I am hoping with the new U-Verse speed tier deployments that I will be capable of attaining at least a 45Mbps download. I know it will require pair bonding, or in laymen terms, some rewiring.
I WOULD LIKE TO KNOW THOUGH IF I REALLY WOULD BE ELIGIBLE FOR THE SPEED UPGRADE. IF YOU KNOW, I HOPE I GAVE A DETAILED LOOK AT MY LINE, AND I WOULD LIKE YOU ALL'S OPINIONS...
Thanks!

For fun, a picture of my VRAD...
