I suffered a major crash in my network last weekend. What ever happened it borked my PWS Raspberry Pi setup. That was when I discovered that the network, specifically the Verizon Quantum router, was no longer getting DHCP assigned IP numbers. I did some tracing and found out that all of my TiVo equipment no longer had IP addresses.
When I went to troubleshoot the Quantum, I discovered that it no longer recognized the FIOS cable that was plugged into it. I checked everywhere for potential hardware breakages that would explain it but it would come up for a few seconds and then disappear. That is when I decided to take the Quantum out of the loop. For one, it was no longer issuing IP addresses from its DHCP server and the TV cable thing. I ordered a Motorola MOCA 2.0 adapter even though the TiVo Bolt was capable of setting up a MOCA network (I might still use this at a later date though). The real problem was the fact that the TiVo equipment (Bolt and 2 Minis) were not responding at all and had taken on Bonjour addresses. The Mini was able to communicate with the Bolt, but could not get back to the TiVo home page to receive updates. It also appeared that this was causing some issues in using the TiVo equipment.
I then added a vlan behind my Cisco router and moved all of the TiVo equipment there. When the MOCA adapter came in, I put it on the FIOS cable and connected it to the same vlan as the TiVo equipment. I then saw that my TiVo equipment had IP addresses and could be updated from the TiVo site.
I determined that the weewx setup on my Raspberry Pi had failed. It was causing kernel panics. I then changed out the RPi hardware and setup a new weewx software build and got the PWS back online.
All of my traceback seemed to indicate that the Quantum had undergone a hard failure, no amount of reseting the Quantum seemed to revive it's capabilities. So I made the decision to phase out the Quantum router. I was able to get to the outside through the Quantum, but only because my Cisco Router has a manually assigned IP address in the Quantum LAN subnet. I did some research and it seems that it is a fairly simple matter to take down the Quantum and bring up the Cisco in its place.
Will report back when I get this working.
This is a blog mostly about techie things, what I am doing to my apartment network on the cheap, IOT, 3D Printing, Raspberry Pis, Arduinos, ESP32, ESP8266, Home Automation, Personal Weather Stations, Things That Go Bump in the Night, and some side issues that need discussing. Remember, sometimes the journey to an end is as much fun as the goal achieved!
