I order 2 on Thursday 4\/22\/2010 , receive today -lrb- 4\/27\/2010 -rrb- . hook the first one up at 3PM , but could not get online so I call Charter Cable at about 5:30 . do not waste you time with the automated service , just ask for a agent . I waste 10-15 minute with the auto service . you 'll need to give the MAC Address to the agent -lrb- this be the second line on the bottom of the unit -rrb- . the first modem , that have be hook up since 3pm , work right away , but the second one do not . the reason be , I give the agent the MAC Address without have the unit hook up to the system first . I tell he this might be the problem , so I hook it up and sure enough , he re-enter the MAC number and it appear on he screen . now I have 2 modem for less than the price of one at best buy . also , they have a 90 day Warranty from Cisco-Linksys -lrb- almost all refurb I have ever see do -rrb- . the bottom of my invoice state `` Linksys offer a 90 day warranty on all they refurbish product . you may contact linksy with any warranty issue . in the event that Linksys can not help you , we will honor the term of the warrranty ! '' . Linksys sell this same item on they website -lrb- find it through Bizrate -rrb- . I have already buy it here for around the same price . if it die before 90 day be out , I 'll repost it .
