I decided to buy my own cable modem because the monthly charge for renting the combo modem/router from my cable internet provider was going to practically double in March. Plus, I had limited configuration access and couldn't really set things up the way I wanted. In addition to the new Motorola SB6141 cable modem, I bought this from Newegg as well: ASUS RT-AC66U Dual-Band Wireless-AC1750 Gigabit Router Although I have a couple old routers lying around, I figured I should get something new. So far, I really like it. It's got a couple USB ports on it, you can use for either communications or storage.I connected a 2TB external HDD setup that I had from my FIOS DVR and now I have my own FTP that I can access from anywhere. If I wanted, I could connect my aircard to the other USB and set it up to switch over to the aircard if my cable internet goes out. Wireless coverage in my house is excellent. Performance is rock-solid, and my stepson told me today that the internet is working better than ever. I didn't even tell him I made any changes, as I did it all last night after he went to bed. The price is a little steep, but this is a solid device.
