Beware of reconditioned cable modems. I purchased one from Woot a few months ago and could not use it because the modem was still registered to another Comcast user’s account. There was nothing I could do either! The other Comcast customer would have to call in and deactivate the modem from their account before I could use it. Luckily Woot was understanding and allowed me to return the product, considering it was unusable.
