Today 1st day using Deco M5.
Found one of the unit having weak wifi signal.
It could not connect to mesh network with error saying distance too far but it's only 3 to 4 feet away.
When I switch it become main router, speed test is getting less than 100mbps for my 300mbps package.
Using the other 2 units is getting full 300mbps speed.
Is there way to boost the wifi signal or unit is defect?
