The router I have right now, I'm very much used to it, even though I've had it for less than a month.
When I'd ordered Verzion's FiOS internet service for this new house I've moved into recently, they've told that they were going to send one to me if I'd paid around seven to eight extra dollars with my billing; I accepted. So far, I'm having no trouble with it at all.
Though, I'm planning to buy something of my own pretty soon (I could purchase it from them, but they're going to charge a good amount of money for it; I might be able to get a hold of something as good for much less), and when I do, I'm likely going to trade theirs in. Only thing I'm hoping is that I don't wind up regretting later on.
