this modem work , mostly . it do not seem significantly faster than the old Motorola , though I be guess it would test faster . there be a diminish return for simple web surfing when the older generation of modem be already capable of load a page in few tenth of a second . download be probably faster , but I rarely pay attention to that anyway , since I have train myself to immediately switch to another task whenever I click on a download button . I be still get request from Windows 7 to connect to broadband via dial-up , so either I trigger something in win7 during the installation process , or it periodically think there be no cable modem . I just have to click the cancellation button a few time , which be annoying , but not a big deal . I have no major issue set up the modem with Comcast in Maryland , though it do take they a few try to get everything talk to everything else . the total time might have be 10-15 minute , vs. the 5 I have be hope for , so also no big deal .
