My parents live out in the Phoenix metro area, and I recently had them upgrade their DSL service to 40/20 from 20/869k. My dad's not very tech savvy, so I'm often called upon to VNC into his computer and show him how to do stuff (or figure out what's wrong since his problem descriptions aren't always very descriptive). Anyhow, it's noticeably faster than it used to be (seeing as upstream is 10x as fast now), but I'm a tad disappointed that it only negotiated at 24/10 (which is still more than they need, but half what they're paying for). I realize DSL is a best effort service, but I wanted to post some modem stats (Q1000, if memory serves) and see how they looked before I spend a lot of effort troubleshooting when I'm out there next week. If they seem normal, then is it worth pursuing this with CenturyLink at all? If they're not normal, what would be the best first step in troubleshooting. I was planning to try and plug the modem in either at the NID or at the feed point for their structured wiring so I can at least rule out a bad phone or filter. Anything else beyond that I should try? I'm in IT (Linux/Mac workstation/server support and some networking), so I'm comfortable at a command line if need be.
Thanks!
Here's the stats from the modem. I can telnet into it and get more data if there's anything else that might be of use:
