Modem stats

I have come across a lot of interesting, technical things in an effort to figure out how to get better DSL line speed and I'd like to ask for some help in understanding my modem's Stats.
It's a Siemens speedstream 4100 that I got with an AT&T DSL package and I'm currently using the AT&T modem & filters with DSL Extreme ISP. The ISP tells me the Siemens modem could be faulty so I've gone into it via an ip on the back of the modem and gotten a lot of information, most of which I don't understand right now. I have access to Technical Data, Stats, Diagnostics check, Connection info and other stuff that is a mystery to me. BTW, the diagnostics pages shows everything as "PASS". Anyway, I'd like to understand what all that info means and can post screen shots or whatever here for you.
Thanks in advance for any help or insights into these modem technical pages.
Jim

 

Thanks for all the interesting and informative feedback from all of you experts here!
LOL, fortunately I have found what I need at several other places on line! I just love the web.

 

Well Jimrich you really didn't give us anything to explain? I personaly had read this thread and was waiting for you to post your screenshots with actual questions, but at lest you found your info. Good luck!
