MacBook Air 13 inches A1466 intermittent WIFI Repairs

In this repair, we have a scenario where the device WIFI works intermittently, first, we replaced the wifi card but that did not work, and then continued on the board, all required signals and voltages were present, but SMC_WIFI_PWR_EN were lower than the threshold, we then reflowed the SMC, and that was how we resolved the issue.
