before I make any tech gear purchase , I always do my research , include a careful review of comment on Amazon . I do this before decide on a new cable modem and be glad I choose the Linksys cm100 . I think the best thing that can be say for any cable modem be that it become transparent to the user -- no issue , no problem , no ongoing fiddle with setting try to get it to work . I be happy to say that the cm100 perform very well for I . I be a cox customer and have have very little trouble with this modem . I have have it about a year now , and only once or twice do I have to do the `` unplug-wait-replug '' action to clear some sort of a bottleneck . and the problem may have be completely unrelated to the modem itself . I do not demand or expect 100 percent perfection from anything , but the cm100 come very close to that standard for I . I would buy one again without hesitation .
