I’ve been very pleased with the performance of this modem. I have multiple devices using the WiFi and all work really well. It was also very easy to setup.
After purchasing and using my cable router for the last few months, my family and I love it. Our home is just under 4,000 sqft and we have not had any issues connecting our multiple devices. The only issue we had with the router lagging was not due to the routers performance, rather it was human ignorance by not purchasing the mesh extender. Once we setup the nighthawk 2200 extender, we have had no issues with lagging or connectivity. Great product.
So I had a great installer and after he left and all was fine another installer was at my neighbors home and blew up my internet. He gave excuses and I called Xfinity and they said in another day someone could come. I called technical customer support and the gentleman on the other end very patiently walked me through resetting administrator password on my equipment. I was very very impressed with his patience and professionalism. This guy is a gem.
