My brand new deco does does not have wifi connection "technically" not totally but the signal is super low as in low,

when connected to the mesh the internet speed is only 0.50mbps or less. Also devices does not transfer to the deco unit

as per mesh technology this is my 5th deco M5. I don't know what happened here.

Also I tried to make a new network id with this mesh and it sucks! We cannot connect to it properly we kept on being disconnected.

Note that the mesh doesn't have any obstruction at all it is in a wide space.

But the LAN/Ethernet is working totally fine.

Please help.
