If you do in fact have an older model of the USR 28.8 (the chipset has an id with 007 in somewhere, you will have problems. From the USR's that I've worked with, there is a problem with connecting to other 28.8's as the older USR uses V.FC instead of V.34. If you establish a V.FC connection, the first bit of line-noise will drop your connection. This is because of the way that the V.FC protocol works. You can upgrade your modem to V.34 for about 29.95 from USR or if you want, you can spend a couple of dollars more and get it upgraded to 36.6. Call USR for details. They'll take your credit card and mail you a chip to drop into the modem. Note though, I've been waiting almost 3 weeks now for a few of these upgrades... -jeff
