Wireless Router Network PC to WiFi to PC Connection Networking Tutorial Using Cisco Packet Tracer
This video demonstrates how two computers communicate over a wireless network using a wireless router in Cisco Packet Tracer. Instead of using Ethernet cables, devices connect through Wi-Fi while still following the same networking principles used in wired communication.
Wireless Router Network (PC to WiFi to PC)
Topics covered:
• Wireless LAN (WLAN) configuration
• SSID and Wi-Fi security settings
• Client association and authentication
• IP addressing within a wireless network
• ARP over wireless communication
• ICMP ping testing over Wi-Fi
Software used: Cisco Packet Tracer
Wireless Infrastructure Mode (Wi-Fi Router)
Laptop )) Wireless Router (( Laptop
• Access point role
• DHCP assignment
• Clients don’t talk directly
DHCP automatically assigns IP → ping works
Wireless Infrastructure Network (Wi-Fi Router) — Packet Tracer
Now we demonstrate modern networking:
Devices connect wirelessly to a router (access point) and receive IP addresses automatically using DHCP.
No cables between the computers.
PART A — Build the Wireless Network
1) New Workspace
File → New
2) Place Devices
Add Wireless Router
Bottom-left → Network Devices → Wireless Devices
Drag Wireless Router (WRT300N) to the center
Add Two Laptops
Bottom-left → End Devices
Drag:
• Laptop0
• Laptop1
Place them near the router (distance doesn’t matter in Packet Tracer)
PART B — Install Wireless Cards (VERY IMPORTANT)
Without it Wi-Fi won’t exist.
Do this for BOTH laptops:
In Packet Tracer the device only has one expansion slot, so:
You must remove the existing wired NIC before inserting the wireless NIC.
So with the Laptop-PT the correct process is:
1. Physical tab
2. Power OFF
3. Drag the existing FastEthernet card OUT
4. Drag WPC300N INTO the empty slot
5. Power ON
6. Now PC Wireless works
Install the wireless card into both laptops.
Laptop0 (& Laptop1)
1. Click Laptop0
2. Go to Physical tab
3. Toggle Power OFF
4. On the left module list, find WPC300N
5. Drag it into the empty slot
6. Power ON
Repeat for Laptop1
Wireless Card Installation
The laptop does NOT have a wireless card, so it physically cannot see Wi-Fi networks until you add one.
You are adding a Wi-Fi adapter module to the laptop’s motherboard.
Packet Tracer laptops have removable components:
• Ethernet card
• Wireless card
• Battery
• Fan modules
You must insert the wireless card manually.
Step-By-Step (slow and precise)
1) Open the Laptop Hardware
Click Laptop0
At the top tabs click:
Physical
You will now see a picture of the laptop internals.
2) Turn Power Off (important)
On the right side is a power button.
Click it so it turns OFF (red)
You cannot install modules while powered on.
3) Find the Wireless Card
Look at the left panel — a list of components.
Scroll if needed and find:
WPC300N
(This is the wireless network adapter)
4) Insert It
Now do this
1. Click and HOLD the WPC300N module
2. Drag it into the empty slot in the laptop
3. Release mouse
The slot is a small rectangular opening in the laptop chassis.
When placed correctly it snaps into place.
5) Turn Laptop Back On
Click the power button again → turns green
Now the laptop has Wi-Fi capability.
How You Know It Worked
Go to:
Desktop → PC Wireless
Before installing → empty / no networks
After installing → wireless interface appears
Real laptops require a wireless NIC to connect to Wi-Fi.
So the simulator makes you add the hardware to teach:
Wireless connectivity requires a wireless network interface card.
Repeat for Laptop1.
Once both can open Desktop → PC Wireless without errors, continue with the Wi-Fi connection steps from Recording #4:
• Configure SSID + WPA2 on the router
• Connect each laptop
• Verify DHCP with ipconfig
• Ping the other laptop
PART C — Configure the Wireless Router
Click the Wireless Router
Go to GUI tab
Set the Wi-Fi Name (SSID)
Top menu → Wireless → Basic Wireless Settings
Change:
Network Name (SSID): SchoolWiFi
Add Security (Required to Connect)
Go to:
Wireless → Wireless Security
Set:
Security Mode: WPA2 Personal
Passphrase: password123
Click Save Settings
PART D — Connect the Laptops to Wi-Fi
Connect Laptop0
1. Click Laptop0
2. Desktop → PC Wireless
3. Go to Connect tab
4. Select SchoolWiFi
5. Enter password: password123
Click Connect
Connect Laptop1
Repeat the same steps
PART E — Verify Automatic IP Addressing (DHCP)
On Laptop0:
Desktop → Command Prompt
ipconfig
You should see something like:
IP Address: 192.168.0.100
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
Now check Laptop1 — it should be a different address but same network.
PART F — Test Connectivity
From Laptop0:
ping 192.168.0.101
(Use the actual IP shown on Laptop1)
You should receive replies ✔
PART G — Simulation Mode Proof
1. Bottom-right → Simulation
You will see traffic go:
Laptop0 → Wireless Router → Laptop1
Devices do NOT talk directly — router forwards frames.
Wireless clients communicate through the access point, which also forwards traffic and assigns IP addresses using DHCP.
