Device Roaming Between Different Extenders
I have Archer AXE75 and two RE220 extenders acting as a mesh network. I bought recently an irrigation controller and it became off-line and then I need to reset again and then connect back to my network, after troubleshooting I found that the controller initially connected to the main router and when it connects to the extender it goes off-line and also the way round when it moves from extender to main router it goes off-line. To prove my theory, I shutdown the extenders for 2 full weeks and never have the off-line issue.
The question is how to make the concerned controller connected to one of the extenders and never change to another extender or even the main router? Or how to make the concerned controller connected to main router and never change to the extenders?
