LED | Status | Explanation |
ACT | Off | The router is powered off |
Blinking | The router is ready and operating normally | |
WAN2 (FTTP/Ethernet WAN) | On/Blinking Quickly | Internet connection is ready for use |
Off | Connection is offline | |
LTE | On/Blinking Quickly | LTE network is connected and ready for use |
Off | LTE modem is not detected or has a serious problem (e.g., Antenna issue, SIM issue, etc.) | |
Blinking | Slowly: LTE modem is connecting. Quickly: Data is being transmitted over LTE | |
DSL | On | DSL connection synchronised |
Blinking | Slowly: DSL connection not currently synchronising or not detected. Quickly: DSL connection is synchronising | |
2.4G / 5G (Wireless LAN) (If applicable) | On | 2.4G: 2.4GHz Access Point is active 5G: 5GHz Access Point is active |
Off | Wireless Access point is inactive | |
Blinking | 2.4GHz/5GHz LED will blink slowly when transmitting over that interface ACT & WLAN LEDs blink rapidly when WPS is ready for WPS clients to connect. After 2 minutes, the router will disable WPS pairing mode |

Factory Reset (Only use if approved by CSL Platinum Tech Support) | Restore the default settings. Turn on the router (ACT LED is blinking). Use a paper clip or similar object to press & hold the Factory Reset button for more than 5 seconds. Once the ACT LED begins to blink rapidly, release the factory reset button. The router will reset with the factory default configuration. CSL Platinum Tech Support will enable the download of the configuration. | ||||

THE SITE IS OFF-LINE AND THE ROUTER CAN NOT BE CONTACTED ON EITHER PATH
1. Check the router is powered on. Ensure the power adaptor is connected to the routers PWR socket, the router PWR switch is set to ON, the power adapter is connected to the mains power socket and switched on.
2. Check the ACT LED is blinking. The ACT LED blinking indicates the router is ready and operating normally. If the ACT LED is off, recheck the router is receiving power as per step 1.
3. Check the LTE/DSL/WAN2 connectivity is established.
If the DSL LED is off, please check connectors are well seated. If connections are OK, swap the filter, cables, or adaptors between the line socket and router. (If applicable).
If the WAN2 LED is off, please check the RJ45 cable is not damaged and is well seated. If the connection seems OK, replace the RJ45 cable. (if applicable)
The LTE LED should be solid. If the LTE LED is off, it indicates no signal is available. Please check the antenna connectors and/or reposition the two LTE antennas. (If applicable).
WAN2 | On/Blinking Quickly | Internet connection is ready for use |
Off | Internet connection is offline | |
LTE | On/Blinking Quickly | LTE internet is connected and ready for use |
Off | LTE modem is not detected, or has serious problem (e.g., no SIM card, Antenna issue, SIM deactivated, etc.) | |
Blinking | Slowly: LTE modem is connecting Quickly: Data is being transmitted over LTE | |
DSL | On | DSL connection synchronised |
Blinking | Slowly: DSL connection not currently synchronising or not detected. Quickly: DSL connection is synchronising |
4. If no resolution, contact CSL Platinum Tech Support.
THE ROUTER IS ONLINE, BUT THE LOCAL LAN EQUIPMENT IS NOT VISIBLE / REACHABLE
Step 1. Check the ethernet connection between the router and local equipment. Please refer to the LAN LED status table above (figure 2.). Check the customer’s local device is powered on and complete a restart if required. If the LEDs on the router’s ethernet interface P1-P5 are not lit, replace the ethernet cable.
Step 2. For WLAN, check the wireless LAN connection is working. Please refer to the LED status table above. Check customer’s LAN device is powered on and complete a restart if required. Check both WLAN antennas are connected to the outer WLAN SMA connectors.
Step 3. If no resolution, contact CSL Platinum Tech Support.
