Check the Wireless Signal

Check the Wireless Signal

The signal LED on your device indicates the current wireless signal status.


1. The Signal Strength LED displays the wireless signal strength that the AT&T Wireless Internet is receiving. 3 or 4 bars indicate that the AT&T Wireless Internet is receiving a strong signal.

Note: 1 or 2 bars indicate a moderate wireless signal. 

Step 1

2. Red indicates no wireless signal, if this occurs or if only 1 or 2 bars are lighting up, move the AT&T Wireless Internet to a different location for best performance. 

Note: Red blinking indicates a SIM card error, SIM checking, or other abnormal status. The Signal Strength LED will turn green when connected to LTE or blue if it is connected to HSPA/3G.
