Overview
What this part is
The iPhone 11 carries its WiFi signal to the antenna through a thin flex cable inside the housing. If it is torn during a repair, pinched under a bracket or damaged by liquid, WiFi becomes weak or drops out often.
This part replaces that WiFi flex. If WiFi is greyed out in Settings, the fault is usually on the main board rather than the flex, and this part will not fix it.

Professional installation
How a technician fits this part
- Power the Apple iPhone 11 off, remove the two pentalobe screws next to the charging port and warm the screen edges to soften the adhesive.
- Open the display carefully and disconnect the battery before anything else.
- Remove the brackets covering the WiFi flex and unclip the old flex.
- Fit the new WiFi flex, seat each connector firmly and refit the brackets and screws.
- Reconnect the display and battery, then test the repair before sealing.
- Apply new adhesive, close the phone and press evenly while it cures.
- Check WiFi range and speed close to and away from the router.
Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my iPhone 11?
Yes, if Settings › General › About shows iPhone 11. It fits models A2111, A2221 and A2223.
Does it fit the iPhone 11 Pro?
No. The iPhone 11 Pro uses a different WiFi flex.
Will this fix WiFi that is greyed out?
Usually not. Greyed-out WiFi normally points to a main board fault. This flex fixes weak or dropping WiFi caused by a damaged cable.
Is it made by Apple?
No. It is a brand new, OEM-quality wifi antenna flex cable made to fit the Apple iPhone 11, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. Opening an iPhone 11 needs heat, pentalobe and tri-point screwdrivers and new adhesive, and the battery must be disconnected safely.
