I have 6 DECO X60 nodes - (AX3000 x 2 sets). Whole Home Mesh wifi 6 System.   I have a fast 1GB optic fibre connection.   How to I find the DECO TP LINK Hardware Version ?    The Firmware version is 1.5.3.  From my router the 1st Deco is giving me Wifi speeds of around 400 Mbps download speed & about 90 Mbps upload speed on Auto 2.4 / 5.0 Ghz GHz.  Which is great.       I have 5 other nodes around my house -all connected by WiFi only.  None of the other 5 nodes give me more than around 90 Mbps download & 90 Mpbs upload speeds.  Even those in the next room about 8 metres away. The nodes all speak to each other and show up very well on the network as 2 of 3 bars.   The Network optimization scan shows as "perfect" .  How do I increase the speed of the 5 nodes connected by wifi ?  Will a simple firmware update do the trick and what is the latest firmware build that has been tried and tested and advisable to install ? EACH AX3000 set of 3 is meant to give Seamless coverage upto 650m2.  I am struggling with 100m2.  What am I doing wrong please ?  Any clear advise on this much appreciated. Thank you J
