# Bridge not online

## The bridge is fully powered by the adapter but the LED keeps flashing red, what to do?

Checks to perform and possible solutions:

**Installation**

Are all 3 antennas correctly and firmly connected?  
Does the power supply has power?   
Is the bridge installed close to a frequency inverter? If so, move the bridge as far away (\>2m) from the frequency inverter as possible.

**Network**  
In the case of Wi-Fi or 4G, is the network strength on the location of the bridge strong enough?

- - Are the correct IP addresses opened up? Check the listed IP adresses [here](https://8677414.hs-sites.com/knowledge/firewalls?hsLang=en).
    - Are MAC addresses needed and if so, registered? In case of a secured ethernet or Wi-Fi network

**Range reduction**

| **Material** | **Range reduction** |
| --- | --- |
| Wood, plaster, glass | 0-10% |
| Brick, plasterboard | 5-35% |
| Metal, concrete, mirrors | 10-90% |
