Cisco DPC3008 DOCSIS 3.0 Cable Modem (Rev 1.0) Bootloader Revision 2.3.1_r3 - d3000-v302r125532-120517a-L2VPN-CMCST.bin - Firmware build date May 17 11:31:04 2012
Belkin F5D8236-4 v1 Router 1.00.02 (Jul 31 2008 22:32:30)
The "routers" Internet flashes amber and goes back to solid blue. It will flash amber on average for 50 seconds, then go back to blue and stay blue on average for up to three to five minutes (this is not exact times) but it is the average.
I recently received this modem as the old modem from Comcast was not allowing full speeds. The modems "online light" is always flashing Amber, and I was told by phone tech, this was normal. They said all looks fine on their end. My signals to them are just fine. They suggest it is a router issue.
Sure, I can bypass the router all together, but my modem will NOT allow me to see any logs to know the issue is happening on their end. I've read many people replaced their routers and still have the same issue, so I want to try my hand at some Tech help before I spend money to replace my router that may not have a problem to begin with. Is there a way for me to collect data on my connection when I bypass the router? I see a login username and password for my modem, but I do not have access to this. Is there a log somewhere?
I've reset both Modem and Router. Comcast phone tech did his magic on his end as well. I've made sure my connection was set to Dynamic. My router/security log does not offer up anything at the times this happens, but I do see several listings for "sending OFFER to a local IP of one of our laptops, but this does not match the times the router net light goes amber.
Just while typing this up, my Internet icon flashed to amber for about 40 seconds, and went back to blue. It did this nine times while typing up this message.
Does anyone have any suggestions or ideas as to why this is happening? Here are the details you may require.

Now, we did flood here with Superstorm Sandy. I had to remove all of the insulation under my house, replacing it this weekend. I do run cat cables under the house. I had someone look at the wires, and they said they looked okay. HOWEVER, this problem started a month or two before the storm hit.
I would rather try to make sure there are no KNOWN issues first, then try replacing cat cables, router, and modem last.
If anyone can help shed some light on this I would greatly appreciate your help. Ideas, suggestions, tips, tools, links you name it I'm looking for it!
