Jimbo.Automates Posted August 10, 2020 Posted August 10, 2020 (edited) I have a new router, a Firewalla gold, and now when I reboot either of my ISY's they both have issues with DHCP and the error and memory lights constantly blinking. I have it configured correctly on the router, but the ISY is saying there is an IP Conflict, when there is not. Sun 2020/08/09 01:44:21 PM System -100 [DHCP] state=INIT Sun 2020/08/09 01:44:26 PM System -170001 [Network] Error: IP Conflict Sun 2020/08/09 01:44:37 PM System -100 [DHCP] Failed Starting Client If I change the DHCP reservation to a different IP, then restart the ISY it works, but then the next reboot as this same issue.

I had trouble with my ASUS AC68u AC1900 router. From what I can figure out it ran short of NVRAM and would not remember, or handle more than about 54 devices at one time. When I had the third party WRT firmware installed it really gave problems as they added even more features and flooded the NVRAM. When I had a power failure, at times, both my polisy and/or ISY could not get an IP address. I found ISY and polisy just gave up after a few tries and tried to function with a IP address of 0.0.0.0. Then nothing worked. At times other devices would not get an IP address issued but other devices seemed to not give up asking the DHCP server and got dynamic addresses most of the time they were needed for the short term. Now, two routers later, my main router is reporting about 67-70 devices simultaneously and ISY and polisy don't seem to fail at booting up from a house power failure recovery. I have never seen any specs on any router that specify any of these hidden problem limitations yet. Now I fear when my main router goes down, all my devices attempt to switch over to my old router again via the mesh switching system and it can't handle things, and then crashes or other nasty lock-up things. I now see why WiFi is not a good HA medium.. Ohhh...when all this was going on the workaround for me was to assign the IP addresses in the devices as well as the DHCP reservation table. That way there was no failure in an IP address grab fight. Edited August 10, 2020 by larryllix
Jimbo.Automates Posted August 10, 2020 Author Posted August 10, 2020 Thanks Larry, but firewalla support figured out what is happening, damn google wifi is responding to the DHCP request when it shouldn't... I'm bummed I need to dump the google wifi, it's been a no brainer and has just constantly worked, but it doesn't work in bridge mode. Looking at the new Orbi's now... 2
