Problems with second router on Coax

I set up a second router following the instruction in the FAQs. It worked fine for several months, then the Network Light started blinking. I have checked over all the steps that I used when I first set up the router and nothing has changed. Anyone have any suggestions other than replacing the router?

Have you checked you MOCA LAN stats?

I see 3 figures in the 23x area for three device. I have 2 STBs and the router so I assume one of the figures is for the second router. When I check the Lan sats for the second router I see 152 for device 3.

152Mbps is not a functional MOCA signal.

Bad MOCA stats are usually indicative of a cabling or splitter problem. Check that all your splitters are bi-directional and are rated 1Ghz or better. Retighten all coax connections.

If that doesn't help, try moving the second router to another location. If the bad MOCA stats follow the router, then you probably have a bad router.

I changed the splitter and the cable from the splitter to the router. I see 164 for lan stats on device 3. Looks like I have a bad router? Thank you for your assistance.

I disconnected the two items that are normally connected to the second router. I still see two devices which I can not identify. One of them is Device 3 IP 169.254.1.100 Mac Address 00:21:80:49:7e:d9 Device 2 IP 169.254.1.184 Mac Address 74:f6:12:f3:14:184 . There is nothing connected to the ethernet slots on the router and I have turned of wireless connection. How do I disconnect these two IPs?

Those MAC #s are Motorola devices, so they pretty much have to be STBs / DVRs.

Device 2 doesn't have a valid IP address, so it's not getting to the DHCP server on the Actiontec.

Those are private, non-routable IP's that the STB's are reporting - since they can't reach a DHCP server. In this case, it is the BHR's DHCP server they can't reach.

LOL. I knew as soon as I posted that someone was going to take exception to my calling 169.254.x.x invalid addresses (I was in a hurry).

169.254 addresses are indeed valid IP addresses, but as nycdave See Profile indicates, they are self assigned Link Local addresses. The STBs use the 169.254 addresses in two situations:
1) If the STB is unable to contact the Actiontec DHCP server.
2) Link local addresses are also used by the STBs to communicate configuration information among themselves.

Problem solved:
I realized that my problem with the blinking light began when I put a splitter before my second DVR. I checked the splitter that had been installed by Verizon and found a small unit between the incoming line from the ONT and the splitter. I removed it and put the line directly into the splitter. No more blinking light. Thank everyone for your help.

Ahh, must have had an attenuator on the line, splitting it attenuated it again which could cause issues (and obviously did).

Hmmm. An attenuator?

Yes, installers put attenuators in during FiOS installs because the signal is so hot coming from the ONT they need to lower it in some instances.

Picture of said small unit?

nycdave can correct me if something has changed in the past 6 months, but there should be no need to place an attenuator, and if one is needed, it is supposed to go right at the input of the STB, not on the in port of a splitter.

During my install 4 (?) yrs ago, the installer put the attenuators at my splitters......

My install was about 4 years ago also. I only had 3 units on the coax line. I had two STBs and the router. Now each of the STB lines has a 3 way splitter. That is the reason I needed to take out the attenuator.

That explains it. The change in what VZ considers 'acceptable' RF levels at the STB happened about 2-3 years ago, IIRC.
