I have a 8 year old modem hooked up to a 3 month old router to get wifi via my macbook pro. The macbook is less than a year old as well and has lion. For the last couple months my modem will randomly stop working about once a day causing me to reset it in order for it to work again. Recently it will shut up and it will not work for several hours at a time if at all until the next day. I believe it has something to do with the old 8 year old modem not connecting correctly with the router considering wifi was rare 8 years ago. I would like to know what kind of modem i need to connect with my linksys E1200 router. I called century link and it was some foreigner that had no idea what she was talking about. She kept insisting i get a 2 in 1 router modem but considering my router is only 3 months old i would rather go the cheaper route and get just a new modem. Any suggestions?
