    This is a great modem for the price. This is the same brand modem that the cable companies charge you monthly for.

    It is easy to set up but the range of the signal isn't the best. We do have it placed in an entertainment center in the basement which doesn't help.

    It's ok I suppose for the price. Good for just surfing the net. The drawback is that if it looses power it takes about 10 mins to start back up.
