🟢 What Does a Flashing Green Light Mean on Amazboost?
A flashing green light on your Amazboost signal booster typically indicates that the system is actively reducing its gain to prevent interference. This condition is known as Auto Gain Control (AGC) or Oscillation Protection.
In simple terms:
- ✅ The booster is working
- ⚠️ But it’s adjusting itself because of a signal problem (like too strong an incoming signal or feedback from the indoor antenna)
🔍 Common Causes of Flashing Green Light
- Antennas Are Too Close Together
If your indoor and outdoor antennas are placed too close, it can cause oscillation (signal feedback loop), which triggers the booster to reduce gain and flash green. - Strong Outside Signal
When the outdoor antenna receives a very strong signal (e.g., if you’re near a tower), the booster may automatically throttle itself to avoid overloading. - Improper Antenna Placement
If the antennas are not isolated by enough distance or walls, it can cause interference, leading to flashing. - Cable or Connection Issues
A loose or damaged coaxial cable might create unstable signal conditions that confuse the booster’s logic.
🛠️ How to Fix Amazboost Flashing Green Light
Here are some steps you can try to stop the flashing green light and improve performance:
✅ 1. Increase Separation Between Antennas
Try to increase the vertical or horizontal distance between the indoor and outdoor antennas. Ideally, aim for 20 feet or more of separation with a wall in between if possible.
✅ 2. Reposition the Outdoor Antenna
Point the outdoor antenna away from the tower slightly, or place it in a location where the signal is slightly weaker. You can also mount it higher or lower to control signal strength.
✅ 3. Check Cable Connections
Ensure that:
- All coaxial cables are securely connected
- There’s no damage or corrosion
- You’re using the cables provided or ones with proper shielding
✅ 4. Let AGC Settle
In some cases, the light may flash temporarily during startup or adjustment and then return to solid green once stable. Wait a few minutes to see if it resolves itself.
✅ 5. Use a Signal Meter App
Install a signal strength app (like Network Cell Info Lite for Android or OpenSignal for iOS) to fine-tune antenna placement based on actual signal readings.
💡 When to Worry
If the flashing never stops, and you’re not seeing any signal improvement indoors, it may indicate:
- The gain is being throttled too much
- The booster is caught in a feedback loop
- There’s a possible hardware fault
In these cases, try resetting the system or contacting Amazboost support for additional diagnostics.
☎️ Contacting Amazboost Support
If none of the above steps work, Amazboost offers tech support via their website or Amazon product page. Be ready to provide:
- Your model number (e.g., Amazboost A1, A3B, etc.)
- Description of the LED behavior
- Photos of your setup if possible
📝 Final Thoughts
A flashing green light on your Amazboost isn’t necessarily a bad thing, it’s often the booster doing its job to protect the signal environment. With a few simple adjustments to antenna placement and cable checks, you can usually fix the issue and restore strong indoor coverage.
