I had an RCA modem from Mediacom. It was very unreliable and I never seemed to get up to my rated speed, upload or download. Today it quit working and I didn't want to wait until Monday to go to Mediacom and swap it, so I went to Best Buy and bought a Motorola modem. HOLY COW! My speed took right off, I'm getting 12mbps download and over 1mbps upload. Anyone else had similar experience? Are the RCA modems just junk, or what?
