Hello. I recently did a passthrough IP on the main ISP router to which the main Deco is hardwired to, including disabling ISP router's wifis, disabling firewall etc, Fixed DHCPS etc. This caused the internet speeds to almost double and get very close to the juice that I pay the ISP for, which is great. However, I have 2 more nodes besides the main one, the first one cable backhauled to the wall panel (on the app shows as hardwired to the main deco), the second one is connected to main via wifi. After I did the passthrough, these two non-main nodes are blinking red and once in a while a solid green, but then back to blinking red most of the time, which indicates that the connection is unstable. 

However, the app link shows that everything is fine, I did optimization also/no interference. Speeds are still good, although the speed test occasionally shows 100-200 Mbps lower for uploads, not sure if its related to the blinking.

Is there a way to fix the blinking and is the set-up OK? I'd like it to be solid green on all units just for the peace of mind. ISP router is BGW320, TpLink model XE75. Deco is set to AP mode, all firmware up to date. Thank you.
