Can’t set IP Address of modem to match existing network!!

Summary: Don’t buy this modem if you plan on setting your IP Address to anything in the 192.168.1.* to 192.168.7.* range. They reserve those numbers for their Guest Network, even if you aren’t using that "feature".
Summary: Finally decided to upgrade from my older Netgear router to the C3700. The first 2 weeks it worked perfectly. Then out of nowhere, certain apps on my wife and I's phones and certain websites would either work very slowly or not at all. Facebook, Netflix and Pandora worked extremely slowly if at all.
Summary: Won't lock on connection and bandwidth varies excessively. The cable technician showed a steady 110 Mb/s on his specialty device, but this device varies between 15 and 45 Mb/s (on a 50 Mb/s limit). The connection light keeps blinking.

Total waste of money and product warranty is deceive

Summary: I bought this device to work with my Comcast Xfinity connection and this model as expected worked out of the box. But don't invest in this particular model at all if you are someone who is concerned about stable connection as this device fails to provide you stable wireless connection.
Excerpt: Installation was easy, supporting documentation was clear, and performance was good. And then we discovered that our VPNs did not work. Some sources on the net said that the C3700 modem does not support vpn while others hinted that it did. The Netgear tech support person said it did not.
