I purchase this to take the place of a sb6120 that my grandson decide need to be hit against a wall . oh well . anyway , it appear to function the same as the 6120 . I do notice that on a few speed test I do go over 62mb . I never get over 59mb on the 6120 . now do that mean it be faster or better ? who know ! I know I do not know ! I have notice a uptick in the wireless network . I be run the modem through my latest generation Apple Wireless with my iMac hard wire via ethernet . I also use a extreme to extend the network as the speed drop on my wireless network in the front of the house . so the modem work well , do not seem to heat up , keep the signal , look nice , have pretty button , ok I be ramble ... ... ... ... look it work . if and when it act up I will update my review to indicate problem .
