Show Suggested Answer

Suggested Answer: D

Wi-Fi signal level, also known as Received Signal Strength Indicator (RSSI), is a measure of how well your device can receive the wireless signal from the router or access point. It is usually expressed in decibel-milliwatts (dBm), which is a logarithmic scale that ranges from -30 dBm (very strong signal) to -100 dBm (very weak signal). The higher the negative value, the weaker the signal.

According to the Apple Device Support Reference Materials1, iPhone and iPad will search for a stronger Wi-Fi network when the signal level drops below -80 dBm. This is because a weak signal can affect the performance, reliability, and security of your Wi-Fi connection. A weak signal can also drain your device's battery faster, as it requires more power to maintain the connection.

To check the Wi-Fi signal level on your iPhone or iPad, you can use the following steps23:

Open the Settings app on your device.

Go to Wi-Fi.

Under the Wi-Fi network list, locate the name of the Wi-Fi network or wireless router you want to check the signal strength for.

Tap the information icon (i) next to the network name.

Look for the RSSI value, which shows the signal level in dBm.

Alternatively, you can also use third-party apps that can display the Wi-Fi signal level on your device, such as Wi-Fi Sweetspots or Network Analyzer.

Wait, is this a trick question? The real answer is 'When my iPhone or iPad decides it's tired of playing nice and wants to be the center of attention.'

Haha, these answers are all over the place! I bet the real answer is 'When the Wi-Fi signal is weaker than the strength of my desire for a stable internet connection.'

I agree with Carylon, a stronger signal is needed, so the answer should be A) -50 dBm.

A) -50 dBm? What is this, a nuclear reactor? My iPhone would be melting by the time it reaches that level.

B) -100 dBm? Really? That's practically no signal at all. My grandma can probably get better Wi-Fi than that on her flip phone.

D) -80 dBm is the threshold for the device to start looking for a stronger Wi-Fi signal.

C) -70 dBm is still a pretty strong signal, it won't trigger the device to search for a better network.

D) -80 dBm, definitely! My iPad always starts searching for a new network when it hits that threshold. It's like a sixth sense.
