RBR750 Magenta Light

A "new one" for me.  RBR750 with firmware v7.2.6.31 is showing a magenta light on the front panel and the web interface Home Page displays the message "Waiting".  However, devices connected to the RBR750 appear to be working correctly:

  • Can ping any IP address on the internet
  • Can use DNS to resolve the IP address of common hosts (ford.com, etc.)
  • Web browsers can open Amazon and other internet web sites.
  • Email app functions normally.
  • External device can VPN into the router LAN and access the router web interface.

My guess is that there is some specific test that the router performs to establish that a valid internet connection exists, such as pinging a specific IP address, connecting to a specific host (perhaps at Netgear), etc.

 

Before I set up Wireshark to capture every damn packet passing through the WAN interface, does anyone happen to know precisely how Orbi routers establish that there is a connection to the internet?

 

Thanks

    Means the RBR is not getting good services from the ISP hardware or possible something on the RBR is detecting an issue between the RBR and the ISP modem. v.31 isn't great FW from what I've seen. How long have you had v.31 loaded on the RBR? 

     

    I'd check the ISP modem first and see if there is any cable connections or event logs entries. Make sure the signal up to the modem is GOOD for sure. 

     

    Just does a DHCP check I believe and if it's not getting a IP address correctly or at all, PINK maybe seen.

      Problem solved.  Some time ago, I changed the DNS to point to a Pi-hole server and then subsequently updated the Raspberry Pi operating system.  Although it doesn't seem to affect any user devices, the Pi-hole server seems to not play nice with the RBR750.  After switching RBR750 DNS to CloudFlare and Google, "all happy".

       

      Have another question:  On the RBR50, enabling LAN/WAN packet capture on the debug page resulted in two Wireshark pcap files:

      • lan.pcap
      • wan.pcap

      Enabling LAN/WAN packet capture on the RBR750 debug page results in only one file: BR.pcap, which appears to not include anything from the WAN port.  The user manual does not mention the debug page options at all.

       

      Question:  How would a user determine "What's going on?"  i.e.

      • The LAN/WAN capture feature has been changed to capture only the LAN ports, but the web page text was not modified to reflect the change?
      • The LAN/WAN capture feature is supposed to capture both the LAN and WAN traffic, but is not working correctly?
      • or...... ???
