Solved the Problem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Solved the Comcast problem. My old router worked just fine, unfortunately Comcast decided not to support that router any more. I cannot say that this router is any better than the one I was using.

Didn't improve speeds
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I have Cox preferred package internet. My old modem could download files up to 5 MB/s. MegaByte not Megabits. This new modem actually slows my speed down to 2.5-3 MB/s. :(

Tends to Time-Out about once a week
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.A bit frustrated that I need to reboot this modem at least once a week in order to keep it operation for internet use. Otherwise, it seems to get the job done.

Average Modem
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Cox recommended that I get a faster modem to support their speeds. Honestly was no faster. As long as yours works, I would say save your money.

Did not meet expectations
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I wanted to stop renting a modem from Comcast and so I bought the Arris modem / router for xfinity. I regretfully unplugged my netgear router and initialized use of the new modem / router. I have a small - 1500 sf house and the wifi coverage is not acceptable even for a house this size. I'm actually going to pack it up and return it today after 30 days of dissatisfaction.

does not work with time warner hawaii
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased this to replace my isp provided leased modem because I was experiencing heavy random lag. I tried a different modem on the same line with no lag so it had to be the modem I had. Anyways, I called tw hawaii and had it all setup. It workeed for less than 1 min before it wouldnt do anything. I know pc's mind you.. I build all my pc's myself. My current build is an i7 o/c at 4.3ghz liquid cooled with a 780ti and 16gb of ram running win 8.. anyways, I called tw twice about it and they couldnt figure it out. So I bought the other model just like this one which supposedly only handles like 160gb dl? Doesn't matter because I dont have a dl speed anything close to that.. which that model works perfectly! If your a hawaii resident and youre looking for a new modem, pass on this one. I told bestbuy and tw about this modem model not working and tw is looking into it.

Sold something that I didn't need
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.OK, here is the deal. I bought a computer for my 79 yr old mom. That included a printer and some HP ink subscription. However, what I wasn't told is that the printer and the ink subscription requires WIFI. This modem does not have WIFI. I am about 500 miles from my Mom... no way to make this right.
