    Amazing Modem,Next-gen Speeds, needs certification

    Excellent High-Split and Next-gen HighSpeed ready modem, great management screen, capable of even bonding the 2.5G with 2 x 1xG to get to 4.5G aggregate bandwidth. Powerful chipset capable of competing with the very best OEM modems like ET2251 from Spectrum. The only slight downside is that it needs to be fully certified with Spectrum to run on High-Split and full upload and download speeds. I believe Netgear is working on this, but until they've got it fully certified with your provider, you're in limbo: you have one of the best modems available for next-gen Internet speeds, but its speed is locked down by provider policy.
