I recently upgraded my Deco X90 system to firmware 1.2.2 and I've been having issues with connections between the main and satellite units ever since. I have 2 nodes in my system and I use wireless backhaul between them, with a distance of one floor between the units. They've been previously extremely stable with no issues. Since upgrading to 1.2.2 I've had trouble getting the units to connect to each other at the same distance they were before. I've factory reset the network a few times and have swapped which unit is the main one and which is the satellite but it hasn't improved things. I've currently had to move the satellite closer to the main unit to get any kind of stable connections between them, but this is not idea. Is this a known issue or couid someone help me diagnose what's going on here?
