[Help] LAN light on front and network activity lights on the back not working

Post by gosavip »

Hello - I have an F2-223. It has the latest TOS available for the hardware. Recently the LAN light on the front of the NAS and the network activity lights on the network port on the back have stopped working. I have tried both ports on the back. I am able to connect to the NAS and it operates just fine. I have restarted multiple times. Network activity lights on the router work. I have tried different cables and ports on the router. HDD activity lights on the front work. Power light works. What else can I check?

Thanks

Could you please share your current BIOS version and exact TOS system version?

How to check the BIOS version:
Go to TOS Web UI > Control Panel > General Settings > System to find the BIOS version.

Thank you for your cooperation.

My NAS was connected to 100Mbps network. Once i connected it to the 1Gbps network port, the lights started working. Thanks Mike and EriChan.
