I really don't want to buy my own modem since Time Warner gives me one with service (no extra rental charge). They are supposed to be going DOCSIS 3 in my market to compete more with U-Verse, so I may get a new one soon if I upgrade my speed tier. I don't think they'll give me a new modem unless I can prove something is wrong with the current one. Since my internet connection is stable I really have no recourse.

I did put the ATA behind an Airlink 101 AR430W running DD-WRT and have had no problems with it so far. I'll update if that changes.
