Input:
I purchased this same router a few years ago, but this one is made differently than the old one. I'm guessing this one is a revised design because it works better than the old model. The only complaint I had about that one was each time I had a power surge (my PC line is connected to an A/C in the summer) the router would reboot even though I had the router and PC connected to a UPS and line conditioner. That's been fixed in this model. It still works flawlessly in all other areas. Easy to setup. Highly recommended.
