Rated 1 out of 5 by Not for Windows 8 Have had trouble since I bought this modem. Previously had the UM185 and had no trouble using that one with Windows 7. Now have new laptop with 8 and that may be the problem, not the modem, but if it doesn't work, it doesn't work. Many times it just kicks you offline after 3-5 minutes. Would be better to wait until Windows 8 get rid of more problems. March 10, 2013
Rated 4 out of 5 by Love it! I use this modem daily and have not had any issues at all with it. This unit is plugged into my laptop which goes all over the U.S. with me. No problems at all and no out-of-service messages. Love it. March 28, 2013
