Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers Generation 2 Software Configuration Guide
Configuring the Wireless Device
The following sections describe how to configure the wireless device on the Cisco 1941W integrated
services router (ISR):
• Starting a Wireless Configuration Session, page 247
• Configuring Wireless Settings, page 249
• Upgrading to Cisco Unified Software, page 255
• Related Documentation, page 258
Note You can upgrade the software on the device to Cisco Unified software. See the “Upgrading to Cisco
Unified Software” section on page 255.
Note The wireless device is embedded on the router and does not have an external console port for
connections. To configure the wireless device, use a console cable to connect a personal computer to the
host router’s Console serial port, and follow the instruction to establish a configuration session.
Starting a Wireless Configuration Session
Enter the following commands in global configuration mode on the router’s Cisco IOS command-line
interface (CLI).
SUMMARY STEPS
1. interface wlan-ap0
2. ip address subnet mask
3. no shut
4. interface vlan1
5. ip address subnet mask
6. exit
7. exit
8. service-module wlan-ap 0 session
