Firewalla Issues w/ Technicolor C2100T Router

I'm having issues using Firewalla with the Technicolor C2100T router. When I originally set up our Firewalla about 2 weeks ago, we were using the ZyXEL C1100Z router and Firewalla worked very well. However, on Dec 29 we upgraded our CenturyLink internet service from 100mbps to 1000mbps and were forced to upgrade the router to the Technicolor C2100T.

I reset Firewalla to factory settings and deregistered the device from my iPhone and got Firewalla working with the new router. However, it does not work reliably. Firewalla seems very sluggish when responding to any change--approving a new device takes 30-60 seconds. And in some cases, Firewalla has blocked some of my family's devices when they 1st join the network. In one case (a Windows 10 laptop), I couldn't get Firewalla to allow internet access at all, even though the device was approved with status = Monitoring according to the iOS app. For now, I've disabled Firewalla by setting Monitoring Mode = Off.

As I said above, Firewalla worked well with our original router so I'm hoping that these compatibility issues with the new router can get resolved eventually. I noticed 2 other Technicolor models were on your list of routers that do not support DHCP mode.

Drew, unfortunately, there are some routers just don't like the Simple mode. Don't worry, we have two other modes for you to play with.

You can read them more here https://help.firewalla.com/hc/en-us/articles/115004292514-How-does-Firewalla-Intercept-Traffic-

The DHCP mode may work if you can disable DHCP server on the Technicolor. If you can't disable, then limit the DHCP range to just that of Firewalla. If both not working let's look at last option.

In the manual mode you are in (The see the last section of the article.) There is an overlay 192.168.218.x (or 192.168.168.x if already using 218). Which means, if you statically configure some of your 'important' or monitored devices to have IP addresses in that range, they will get monitored.

Knock on wood, but I seem to have gotten past the issue with Simple mode. I applied an update to the Firewalla device and now Simple mode works for all of our devices (that I know of).

Thanks,
