Devices not choosing strongest signal node
So, I picked up a Deco XE75 (not pro) system about a week or so ago. Set up was easy and it works fine. Still need to do some fine tuning to get the satellite node to maintain getting a strong signal. My house layout is complicated. I may need to buy a 3rd node. My question has to do with my devices locking onto the node with the best signal.
Not sure if initially I had to manually assign fixed devices like ROKU streaming device, smart tv, and some others to a specific node or if it found the best node on it's own. My system has 2 very good battery backup systems. My internet fiber modem is on one and my Deco XE75 MAIN UNIT is also on a battery backup. My satellite node is not on a battery backup. Just plugged into an outlet. I did notice that when I had a power glitch (twice so far), the main unit was fine because of the battery backup, but the satellite node had to reboot. No problem; however, during that amount of time rebooting, my devices locked onto the MAIN unit. (Because it still had a signal; 1-2 wifi bars). But when the satellite node rebooted and was good again, the devices STAYED locked into the MAIN unit even though the satellite node was very close and had a completely strong signal. I waited a long time; 20-30 minutes, but the devices were still locked into the main. My mobile devices like cell phones and tablets would move to the satellite node when I moved to that part of the house. But the fixed devices in the area of the satellite node still stayed connected to the main.
If I manually assign the devices to the satellite node, it connects, and then I can set it back to "AUTOMATIC" again and it will stay. Just wondering why the devices don't automatically connect to the strongest node. I could just manually assign the fixed devices that never move around, like Roku, Security camera, smart tv, etc. to the satellite node, but I thought the mesh network somehow would talk to each other and coordinate which device it would take. Or is it simply that if the power goes out on the satellite node, and the main is still operating, that the device will lock in and never move unless I MANUALLY assign it.
Any thoughts????
Thanks
