LED explained
| LED | Color | Description |
|---|---|---|
| WWAN | Solid green | Indicates the modem is receiving power and is associated and authenticated but not receiving or transmitting data. |
| Fast green blink | Indicates the modem is receiving power and is associated and authenticated. The blink rate is proportional to the transmitted and received data rate. | |
| Slow green blink | Indicates the modem is receiving power but is not associated or authenticated and is searching for service. Check the antenna, cable, SIM card, or the user account with your service provider. | |
| Off | Indicates the modem is in reset mode. | |
| RSSI | Solid green | Indicates a high RSSI (greater than -69 dBm). |
| Medium green blink | Indicates a medium-level RSSI (from -89 dBm to -69 dBm). | |
| Slow green blink | Indicates a low-level RSSI (from -99 dBm to -89 dBm). | |
| Off | Indicates the RSSI is less than -99 dBm. Check for proper antenna attachment. Adjust antenna placement and orientation. | |
| Solid amber | Indicates no service is detected. Relocate the equipment. | |
| HSPA+ | Solid green | Indicates HSPA+ is in service. |
| Off | Indicates that a non-HSPA+ is in service or that there is no service. | |
| LTE | Solid green | Indicates LTE is in service. |
| Off | Indicates LTE service is not being used. | |
| GPS | Solid green | Indicates the GPS is active. |
| Off | Indicates the GPS is not active or not detected. |

This configuraton relays on EHWIC-3G-HSPA+7 configuration therefore not all trouble shooting steps are included here. For deep deep dive trouble shooting please refere to EHWIC-3G-HSPA+7 config page or references links.
Configure APN profile
APN configuration is stored on the modem nvram not on the router it self. Cisco IOS provides interface to manipulate the modem and modem profiles with following syntax:
Use the command below to configure Vodafone contract profile:
Define AT command in a chat-script
Chat script should be applied in global config mode. Please remember that dialer name is a case sensitive.Syntax
Command to apply:
You can manually execute the chat script if needed for debugging purposes. Here LTE is the chat-script name and 0/0/0 is cellular interface
Configure line interface
This line interface information sets low-speed asynchronous “control” interface which communicates with the modem. The line x/x/x number is the same as cellular x/x/x interface number.
Issue show line to find out what TTY line number is used to communicate with the modem
!Note - previously used on EHWIC-3G-HSPA+7 card, commands rxspeed 21600000 and txspeed 5760000 here on line 0/0/0 have no effect; we should use modem AT commands instead. These will be defaulted to rxspeed 100000000 and txspeed 50000000
Configure the Cellular interface, NAT and cellular routing
Cisco Hwic Card
Local lan is connected to Gi0/1 and all traffic is NAT overload'ed through Cellular0/0/0 interface. There ip 10.0.30.1 is a default gateway for local LAN hosts. From IOS 15 ip nat inside / ip nat outside legacy commands can be replaced by ip nat enable. Please visit NVI - NAT Virtual Interface.
Below is standard config for DDR, where dialer monitors idle time and will bring Cellular interface down when no interested traffic is detected. This is for the subscription plan with number of minutes and data allowance.!Note: if Cellular interface goes down it will not resolve DNS request resulting with no interesting traffic detection and it will not bring interface up.
- Verify idle timer
Dialer interface here Cellular 0/0/0 will be always on. It is good for unlimited data/minutes subscriptions. For reference please check Cisco Software Installation Guide
- Option 1. Setting up idle timer to indefinite
Add dialer idle-timeout 0 command under Interface Cellular 0/0/0.
- Option 2. Dialer-Persistent Configuration with External Dialer Interface
The only option to tear down a call is to shutdown Dialer 1 interface.
Cisco 1941 Ehwic Slots
- Verify - Dialer-Persistent Configuration with External Dialer Interface.
Output below has been snapped when connected to Vodafone contract profile.
- Option 3. (bonus) It is using
dialer watch-listcommand
Below are included a few lines from the optional dialer watch-list option, these are only included because of the very clear comments included. Potentially these could be used to develop to full config.
- debugging of persistent dialer profile
clear interface
When dialer persistent is configured, the clear interface command clears unsuccessful dial attempts on a line without interesting traffic, and then the dialer software attempts to bring up the connection as persistent.
- Shutting Down an Interface Configured for Dialer Persistence
Fully tears down a persistent connection and prevents the software from attempting more dialing.

- Conclusion
Diversity antenna does not improve significantly the link quality
sh cellular 0/0/0 radio command on 4G-LTE card does not include Service Provider (like Vodafone) in stats
