There is a problem with the WIFI signal of my device.

Question

I found that the WIFI signal of the device is weak and I can't detect WIFI. What should I do?

Answer 1

1. Confirm that the WIFI antenna and the feeder head are in good contact;

2. Check whether the WIFI antenna is broken or broken.

3, replace the new WIFI antenna for testing

If the test is OK, there may be a bad WIFI antenna itself;

If the test is NG, it may be a problem with the motherboard. Check if the WIFI connector is soldered or not. Check the mainboard WIFI circuit.

4, confirm the replacement module.
