Hello everyone, My first post on this forum so greetings to everyone. We’ve recently bought ES450 Airlink router as a fallback for our Lantronix. I’m trying to set some initial configuration however I am not able to connect to the ACE Manager via web. I’m connected through ethernet cable and I’ve set the proper address on my laptop (192.168.13.0/24 subnet). However the [http://192.168.13.31:9191](http://192.168.13.31:9191) is not responding. I can ping the device and access 192.168.13.31:8088 (which says Not found). I am able to enter the recovery mode and fetch the logs if that could help. Appreciate any help on this ---

Hi RaV, Welcome you to our community. Please share with me the screenshot of the ping result (ping 192.168.13.31) You can try logging into the ES450 by [https://192.168.13.31:9443/](https://192.168.13.31:9443/) ---

Hello Donald, Thanks for the reply. I am able to ping and access by the [https://192.168.13.31:9443/](https://192.168.13.31:9443/) you’ve provided. Thank you. ![es450_ping](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/5/5eb389f2df57535467a5ff03ed0e2228b0b85392.png) I’ve set the LTE connection and it seems to be working but the Network indicator is flashing Red/Amber so I don’t know if that’s the correct behavior ---

Hi RaV, The Network indicator flashing Red/Amber means the gateway is unable to locate the required radio module firmware. You must upgrade the radio module firmware for the gateway.
