Do you need more of the page? The bottom half seemed to be just DNS type addresses and MAC info.
We called AT&T earlier today. Support said they saw something or other wrong with the line and flushed it and will monitor it for 48 hours for further issues. After they flushed it, speeds and consistency jumped back up to normal, but a few hours later the DSL light went red again and dropped connection a couple times, coming back in at the slower, jumpy speeds for a couple hours. It seems to be back up to normal speeds again currently, but still if there is anything on my end I can do to add stability, all the better.
Also, the AT&T tech had us test the modem without the filter on, but didn't let us know if we should keep it off while they monitor things or if we should put it back on.
Thanks for all your help and time.
