c7000v2 being gifted to a friend

I disconnected this c7000v2 cable modem at the end of May because I switched ISP, and I just "filed" it away as a spare. However, now my friend still on that ISP needs a new cable modem. I defaulte...

   What's the IP address of your (unspecified) computer/device when you
do this?

   If the C7000v2 is not broadcasting its/any SSIDs, and if it's not
giving your Ethernet-attached computer a good IP address, then it might
be in more trouble than you think.

   I'd try assigning static IP[v4] parameters to the computer, like,
say:

      address: 192.168.0.10
      netmask: 255.255.255.0

Then, when that doesn't help:

      address: 192.168.100.10
      netmask: 255.255.255.0

But I would not expect much.

   Did you also look for the LED descriptions and "Troubleshoot"? Even
without an ISP connection, I'd expect it to settle down and respond as
documented after a minute or two. Unless it has a serious problem
(other then not being connected to an ISP).

"appear"? How, exactly, did you arrive at that conclusion?

Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual (at least). Read.

Well, good idea to call ISP to remove MAC before gifting.

However, I have "defaulted" this cable modem 3 times by holding the reset button down for 15 seconds, but now I don't see the default SSID listed on the side of the device, so I plug in with an ethernet cable (all while modem unplugged from house cable connection) and http://192.168.100.1 does not come up. I only get the error message "you are not connected to the internet". I was able to see the default SSID for a few minutes the second time I defaulted it, but was never able to connect via the credentials on the side of the device.
