Your line looks like it's in pretty good shape. You're on the 25/2 profile and it looks like your line could support the 32/5 profile. This would allow you to upgrade to 24/3 Mbps High Speed Internet service if you'd like, and would give you 4 HD streams into the home (instead of the 3 HD streams you currently are limited to, the fourth being SD only).
Your line may not actually support 32, but it sure looks like it should. Check with the U-verse Customer Support team for more details (possible tech visit needed, etc.) Please click this U-verse Customer Service link to send a Private Message (PM) to the AT&T customer service team to help you resolve your request. You can expect a reply via return PM (the blue envelope in the upper right hand corner of this site) in a business day or three.
