Gig good

Title: Giga good Description: Recently had a lightning storm that cooked my router (not Netgear). I've used Netgear switches in the past and have never had problems with them so I decided to try a Netgear modem. It was easy to setup and has been handling everything the network been able to deliver. Lately we've been seeing 940 MBs pretty steadily. Haven't had to do a re-set other than once when a firmware update was applied. Simply put- it does its job quietly and efficiently in the background like it was designed to do. I was surprised at how cool the unit runs. The previous cable modem ran pretty hot. I'm pleased.

Easy set up

Our old Netgear router finally died after 7 years. These things work really hard and 7 years is impressive. Got this one delivered via Walmart . Connected it. Called our ISP and gave the MAC address. Online in minutes. Get the speed our ISP promised.
