I was working on some routing labs (static, EIGRP, OSPF) in Packet Tracer (5.3.2), one of the devices in the lab was a wireless laptop & a 2811 router. I had a bit of trouble trying to get the laptop to connect to the router. After some research, I figured it out and thought I would share it here. Here's how I got it to work -
On the router, install the HWIC-AP-AG-B module into slot 0,
power the router back on
Create an ssid for the wireless laptop to connect to
apply a gateway address on the DOT11 interface, & assign the ssid
Create a DHCP pool of addresses to assign to the wireless laptop
dot11 ssid Cisco
interface dot11Radio 0/0/0
ip address 10.10.10.1 255.255.255.0
ip dhcp excluded-address 10.10.10.1 10.10.10.10
ip dhcp pool CCNA
network 10.10.10.0 255.255.255.0
ip name-server 10.10.10.4
Click on the laptop to bring up the properties,
power the laptop down, remove the Fast Ethernet Port,
install the PT-Laptop-NM-1W module, power the laptop back on.
Click on the Config Tab, click on the Wireless button,
change the SSID to Cisco, close the properties window.
Leave the Authentication Disabled.
Pings from the wireless laptop to the 2811 router are now successful!
