I have my network built with 4 Deco x95 units. The main unit is connected to my router modem from Rogers. I have one deco unit x95 wired to the other using the 2.5gb port. The other 2 are connected using wireless.

They are one floor apart from each other, but if I turn off the satellite, I still get a strong signal from the main unit (around 75%).

However, one of the units connected wirelessly was randomly getting blinking red light after working fine for a while. I did try to reboot the main unit and then plug the satellite again, which fixed the problem for a day, and the next day (sometimes on the same day), it started to blink red again.

Now, I am getting a solid red after 4 days without the blinking red light. It doesn't matter how often I reboot the main unit or the satellite or even run the network optimization, and I keep getting a solid red light.

Routers are only one month old.

Any ideas how to get it fixed for good or do I need to send it to repair?
