appears. When the firmware has been uploaded, a new page opens with 
an “Upgrade is successful” notice, and the router reboots.
How to check the status of your router
Why would I want to check the status of my router? Your router status tells 
you whether you have a secure Internet connection and informs you about the 
status of your network-connected devices.
To check your router status using Cisco Connect:
1. 
In Windows, click Start, All Programs, then click Cisco Connect. 
– OR –
On a Mac, open the Applications folder, then click Cisco Connect.
The Cisco Connect main menu opens.
2. 
Look in the upper-right corner of the Cisco Connect main menu. If your 
router is online and secure, you see online secure and a green indicator.
