I've 3 Deco M5 connected to a Gigabit switch that also connects to Internet router.
M5 --- |----------|
M5 --- | Switch | --- Internet
M5 --- | ---------|
Wireless speed while in proximity of the Main Deco are as expected (400 Mbps)
Speed in proximity of the other two Decos are aroung 50Mbps.
To verify that the units have no issues, I've tried configuring each of the slave, in turn, as Main, and the speed indeed reaches 400Mbps when close to the one configured as Main, doesn't matter which one. That should indicate that the all the units are ok.
Has anyone experienced a similar issue ? Am I overlooking something ?
