Wifi IC for Samsung Galaxy S5 Active

The WiFi IC in your Samsung Galaxy S5 Active is the dedicated chip that manages all WiFi functionality — including 2.4GHz and 5GHz band signal processing, network protocol management (802.11 a/b/g/n/ac/ax), connection establishment, data transmission and reception, and power management for the WiFi sub-system. Without a functioning WiFi IC, your Samsung Galaxy S5 Active cannot access any WiFi network regardless of antenna condition or software settings.

If the WiFi Antenna is confirmed intact and correctly connected — and the WiFi flex cables are undamaged and properly seated — but WiFi still cannot be enabled, cannot detect any networks, or causes the settings app to crash when accessed, the WiFi IC on your Samsung Galaxy S5 Active motherboard is the likely board-level cause. A technician can confirm using RF diagnostic tools.

WiFi IC failure is less common than antenna or cable damage but occurs due to liquid ingress reaching the motherboard, power surge from an incorrect charger, physical shock damaging chip solder joints, or component degradation over the device's lifespan on your Samsung Galaxy S5 Active. It is diagnosed after all physical antenna and cable components are confirmed functional.

No. The WiFi IC is a micro-SMD chip soldered onto the Samsung Galaxy S5 Active motherboard. Replacement requires hot air rework equipment, flux, stencils, and professional board-level repair skills. Attempting without proper tools causes permanent motherboard damage.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip has been soldered it is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
