I order this in May . it be now August . I have have trouble with this product since I get it and have call the modem maker tech desk for help . I be tell to contact Comcast about my internet connection . Comcast tell I they would charge I to come out and look . after one recent day of over a dozen drop connection , I have Comcast come out . they tell I the modem be defective . so now , I not only have a charge from Comcast , it be too late to return this $ 70 piece of junk . and when I try to go through Amazon to contact the seller about this purchase , I be block by a message that it be `` too late '' .
