I receive this modem promptly , but when I plug it in , it be dead . no light go on . when I get in touch with the seller , I be tell I would have to send it back and pay for ship both way . I be also tell that I would have to pay a 20 % restock fee , but when I object to this outrage , I be tell that Digital Media Source `` could waive '' the restock fee . furthermore , when I call Motorola Technical support and give they the serial number , I be tell that the warranty on this modem have expire . this mean that the advertising be fraudulent , since the modem be advertise as new . I would not buy this modem if I be you , because if you do , you could end up with a modem which have no more functionality than a rock and for which you would have to pay shipping both way . the tracking number show that the seller receive my package on August 20 , but it be now September 1 and I have receive no refund at all . I do not yet know if I will ever get a refund even for the purchase price without the shipping . beware !
