What to do if Sierra Wireless AirCard 250U amber LED is blinking?
- KKaren SanchezJul 26, 2025
If the amber LED on your Sierra Wireless modem is blinking, there might be a few reasons. First, make sure the modem is correctly connected to your computer. If you're indoors, try moving your computer to a different spot, as buildings can sometimes block the signal. Also, ensure that you’re within the CDMA network coverage area. If none of these steps work, the issue may be with your service provider, so it's worth checking with them to see if there's a network or account problem.
