Controllers/joycons disconnecting, not synching

Im having intermittent connectivity with controllers (joycon, pro controller, 3rd party) on my switch, I have verified that the antennas, both BT and Wifi are firmly corrected and event tested continuity from the antenna board to the switch MB, WIFI seems to work OK although I dont have a real way to test for continuous wifi connection. Issue persist either docked or undocked.

Most of the time the controllers wont connect, and when they do, its only for a short while, and usually just after restarting and only after connecting to a wifi network.

Wireless controller IC seems fine and no damaged capacitors/resistors nearby, also checked capacitors near APU and they are OK.
