Our senior engineering team specializes in motherboard-level diagnostics. Fixing a greyed-out Wi-Fi toggle on an iPhone 4S isn't as simple as a battery swap; it requires precision heat control and high-grade soldering materials. With 15 years in the field, we ensure your logic board is handled with the highest level of care.

The "Greyed Out" Wi-Fi issue is typically a failure of the BGA solder joints:

• Repair Method: IC Reflow or Replacement using infrared soldering stations.
• Chipset: Broadcom Wi-Fi/Bluetooth Module.
• Materials: We use professional-grade flux to ensure a clean, reliable electrical bond.
• Post-Repair: Extensive testing of signal gain and network stability.

1. Internal Assessment: We check for any secondary board issues or liquid damage.
2. Chip Preparation: Shielding sensitive components near the Wi-Fi IC using polyimide tape.
3. Precision Soldering: Re-flowing the solder points to eliminate fractures.
4. Thermal Management: Controlled cooling to prevent board warping.
5. Final QA: Ensuring Wi-Fi, Bluetooth, and GPS functions are fully operational.

• Greyed Out Switch: Wi-Fi toggle is stuck in the 'Off' position and cannot be moved.
• Bluetooth Spinning: Bluetooth fails to connect or scan for devices.
• Intermittent Connectivity: Wi-Fi works for a few minutes before dropping out permanently.
• Poor Signal: Only connecting when standing next to the router.

Is this a software glitch? While it looks like software, the "greyed out" button is almost always caused by a physical disconnection of the Wi-Fi chip on the motherboard.

Do I need to backup my data? We don't wipe your phone for this fix, but we always suggest a backup before any iPhone repair.

How long does the repair take? Postal repairs are returned within 3-5 working days. In-store Canterbury repairs can often be done the same day depending on the current queue.

How much does it cost to fix iPhone 4 Wi-Fi in the UK? Our current specialist repair price is £39.99, including parts and return shipping.

Can I fix my own iPhone 4S greyed out Wi-Fi? Some "home remedies" involve heat, but these are dangerous and temporary. Professional soldering is the only permanent solution.
