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.

Ah, the age-old Wi-Fi conundrum. I'm going with -70 dBm, the perfect balance of 'just enough' and 'time to find something better'.

I agree, it's the sweet spot for searching for a stronger Wi-Fi signal.

That's a good point. Maybe it's D) -80 dBm then.

But wouldn't a stronger signal be needed before searching for a new network?

-50 dBm? That's like trying to communicate with a tin can and a piece of string. I'd be better off using smoke signals at that point.

I bet the iPhone or iPad has a secret algorithm that calculates the perfect Wi-Fi threshold based on the current moon phase and the user's caffeine intake. My money's on -80 dBm, the more confusing the better.

I'll go with -100 dBm, can't go wrong with a strong signal.

I think it's -80 dBm too, it just sounds right.

Ah, the age-old question of when my device decides to abandon ship and search for greener Wi-Fi pastures. I'd say -70 dBm is the sweet spot, just enough signal to keep me connected but not too much to make my device lazy.
