Yes checking the wiring is a good idea.I even opened the telco side of the box and cleaned the wiring.

Got the RF filter but no change. I'm not surprised, but for only $11 is was worth a try.
I checked the telephone box on the outside of my garage, but there's not a jack in it. The wiring is clean and tight, and someone wrote "SNI in garage" inside the box. My house is about 20 years old, so maybe putting the first jack inside was the practice back then.
Good idea about the K56 modem, Charles. I'll look into getting one to try out.
I found some information on the telephone layouts in my area. My CO is 7.5 miles west of my house. The next closest one is 8 miles north, and another is 9 miles south. I live in a telco hole! I've learned that other people in my neighborhood get the same connections I do (28.8K or less) so I doubt there's much I can do. The one piece of good news I heard was that the phone company was installing a DSLAM about 1.5 miles from me. If that's the case, then I may be able to get DSL! :)
One thing I still have a question about is why I get 28.8K connections even when my SNR is as high as 46. My a/d-d/a value is always around 20, so I shouldn't have too many conversions getting in the way (though I realize 20 may be borderline). Here are the stats from a recent connection:
Retrains Requested 1 Retrains Granted 0
Data Compression V42BIS 0/0
Is there anything else indicated here that could explain why V.90 won't work. It worked fine when I took my computer to work (.5 miles from CO) where I consistently got V.90 connections around 46K. I'm not expecting to improve the connection at this point, I'd just like to know more about what's involved with the connection speed.
Thanks again for all the suggestions. - Mark

sorry the filter didn't work man. I'd try a different modem if you want faster speeds. Better do some testing to see what your actual throughput is with your current modem so you know if you are making an improvement.

I notice that in each of the link diagnostics you posted that there's alway 1 retrain showing, does the modem do a double retrain when first connecting?
Tried setting a range for the modem to work within? Try using &U17&N26 (min 28000bps, max 40000) in the Extra Settings. And try changing the &Nn up or down as necessary.

S32=98&U1&N16 you might try this.
