Introduction: Why Default Cisco AP Credentials Matter
Cisco Access Points (APs) - including the Cisco WAP, Business, and Aironet series - are trusted solutions for secure wireless connectivity in SMBs and enterprise networks. When setting up a new access point or performing a factory reset, administrators need the default username and password to log in for configuration.
Most Cisco APs ship with default credentials such as cisco/cisco or admin/admin to simplify first-time setup. However, these credentials are universal and publicly known, making it critical to change them immediately after login to prevent unauthorized access.
Default Cisco AP Login Credentials
Different Cisco AP models ship with different default logins and management IPs. Use the tables below to identify your device’s factory credentials.
Common Default Credentials
| Cisco AP Series / Model | Default Username | Default Password | Default IP Address |
| Cisco WAP100 / WAP300 / WAP500 Series | cisco | cisco | 192.168.1.245 |
| Cisco Business 140AC / 240AC / 340AP | cisco | cisco | 192.168.1.245 or DHCP |
| Cisco Aironet 1815t / 1830 / 1850 | admin | admin | 10.0.0.1 |
| Cisco Aironet 2800 / 3800 / 9100 Series | Cisco | Cisco | DHCP-assigned |
| Cisco IOS-Based APs (After Reset) | Cisco | Cisco | DHCP or Controller-assigned |
Notes:
- Case sensitivity: “Cisco/Cisco” ≠ “cisco/cisco”.
- Standalone WAP models typically default to 192.168.1.245, while Aironet and controller-based APs receive an address from DHCP.
- Newer APs (e.g., Catalyst 9100) use Cisco/Cisco after factory reset when operating in autonomous mode.
How to Access the Cisco AP Web Interface
Accessing the AP GUI (Graphical User Interface) allows configuration of SSIDs, VLANs, security, and firmware updates.
Step-by-Step Instructions
- Connect Your PC to the APUse an Ethernet cable from your PC to the AP’s LAN port. If the AP uses a PoE switch, ensure it’s powered via PoE or PSU. Set your PC’s static IP to 192.168.1.x (e.g., 192.168.1.10).
- Open the Web UtilityLaunch a browser and enter the AP’s IP address: http://192.168.1.245 (WAP) http://10.0.0.1 (Aironet 1815t) Use HTTPS (https://) for secure login if supported.
- Enter Default CredentialsWhen prompted, enter the default username and password (e.g., cisco / cisco). The GUI opens the setup wizard for initial configuration.
- If IP is UnknownUse the ipconfig command (Windows) or arp -a to check the gateway address. Alternatively, connect to the AP console or reset it to factory defaults.
Logging In via CLI (Console or SSH)
For managed or IOS-based APs, administrators often prefer command-line access.
Access Procedure
- Connect via console cable or SSH.
- Open terminal software (PuTTY, Tera Term, or SecureCRT).
- Enter privileged EXEC mode and configure login credentials.
Verification
Tip: On controller-based APs, login credentials are managed from the WLC (Wireless LAN Controller) or Cisco Catalyst 9800 GUI, not directly from the AP.
How to Change Default Credentials
Changing the default username and password is the most important step post-deployment.
Using the Web GUI
- Log in using default credentials.
- Navigate to Administration > User Accounts or System > Management.
- Create a new username and strong password.
- Save the configuration and reboot if prompted.
Using the CLI (IOS / Aironet APs)
Best Practice: Use passwords with at least 12 characters, including uppercase, lowercase, numbers, and symbols.
Resetting a Cisco AP to Factory Defaults
If credentials are lost or login fails, resetting the device restores its default configuration.
Method 1 — Physical Reset Button
- Power on the AP.
- Press and hold the "Mode" button for 20–30 seconds until LEDs flash amber.
- Release the button. The AP reboots with factory settings (e.g., cisco/cisco login).
Method 2 — CLI Reset
or
After reboot, connect via console or web interface using default credentials.
Warning: Resetting erases all SSIDs, VLANs, and wireless configurations. Always back up configs before proceeding.
Post-Login Security Hardening
Changing credentials is only the first step. Secure the AP by following these additional best practices.
| Security Task | Recommendation / Command |
| Enable HTTPS and SSH Only | ip http secure-server and no ip http server |
| Restrict Access by IP | Use ACLs or management VLANs for admin access |
| Set Role-Based Accounts | username helpdesk privilege 5 secret ... |
| Enable 802.1X / RADIUS Authentication | Integrate AP with Cisco ISE or RADIUS |
| Keep Firmware Updated | Regularly update via GUI or archive download-sw command |
| Backup Configurations | copy run tftp: or use dashboard automation |
| Disable Unused Services | Disable Telnet, CDP if not needed (no cdp run) |
Troubleshooting Common Login Issues
| Issue | Possible Cause | Resolution |
| Cannot access 192.168.1.245 | Incorrect IP or subnet mismatch | Assign static IP to PC (192.168.1.x) and retry |
| “Invalid credentials” | Wrong case (Cisco vs cisco) | Retry with case-sensitive credentials |
| Web page not loading | HTTP disabled | Use HTTPS (https://192.168.1.245) |
| AP not visible on network | No DHCP or wrong VLAN | Connect directly via console |
| Lost password | Forgotten or expired | Perform factory reset |
| Login loop | Browser cache issue | Clear cache or use another browser |
Pro Tip: Always document device credentials in a secured password manager for IT maintenance.
Frequently Asked Questions (FAQ)
Q1: What is the default IP address for Cisco WAP access points?
A: Most WAP models use 192.168.1.245. Aironet 1815t and newer may use 10.0.0.1 or receive IP from DHCP.
Q2: What if I forget my Cisco AP login credentials?
A: Perform a factory reset using the mode button or CLI. This restores defaults (e.g., cisco/cisco).
Q3: Are default credentials the same for all Cisco Aironet APs?
A: No. They vary by model and IOS version. Check your AP label or model-specific guide.
Q4: Can I configure AP credentials from a Cisco switch or controller?
A: Yes. In controller-based networks, AP credentials can be managed from the Wireless LAN Controller (WLC) or Catalyst switch GUI under Wireless > Access Points.
Q5: Why is it important to change default passwords?
A: Default logins are publicly known; leaving them unchanged poses serious security risks.
Real Case: Accessing and Securing a Cisco WAP150
Scenario:
An SMB administrator sets up a new Cisco WAP150 in standalone mode.
Steps:
- Connect the AP’s PoE port to a Cisco Catalyst 9200 switch.
- Access via browser → http://192.168.1.245.
- Login with cisco / cisco.
- Navigate to Administration > User Accounts → Create a new admin user netadmin.
- Enable HTTPS access and disable HTTP.
- Save configuration and reboot.
Result:
The AP is now secured with a unique password, HTTPS-only management, and stable connectivity for wireless users.
Advanced Tip - Configure Login via Cisco Controller (WLC/Catalyst 9800)
In a controller-based deployment, credentials are managed globally.
On the Wireless Controller:
In Cisco Catalyst 9800 GUI:
- Go to Configuration > Wireless > Access Points.
- Under General, set Management Username/Password.
- Click Apply to propagate credentials to all joined APs.
Benefit: Simplifies credential management across hundreds of APs from one console.
Security Best Practices Checklist
| Task | Priority | Recommendation |
| Change default password | Critical | Immediately post-setup |
| Update firmware | High | Check Cisco.com for updates quarterly |
| Use HTTPS/SSH | High | Disable HTTP/Telnet |
| Restrict VLAN access | Medium | Assign management VLAN |
| Backup configuration | Medium | Regular TFTP or dashboard export |
| Enable syslog & SNMP | Optional | Monitor for login attempts |
| Implement 802.1X/RADIUS | Advanced | For enterprise authentication |
Expert Recommendations
For enterprise or campus networks using multiple Cisco APs:
- Integrate APs with Cisco Catalyst 9300/9400 switches using PoE+.
- Centralize management via Cisco Business Dashboard or Cisco DNA Center.
- Use role-based accounts for IT staff.
- Schedule quarterly security audits.
Conclusion
Cisco Access Points, whether from the WAP or Aironet series, are built for enterprise-grade wireless performance. To configure them, administrators often rely on the default login credentials (e.g., cisco/cisco or admin/admin). These allow first-time access via GUI or CLI for setup.
However, default credentials are public knowledge - changing them immediately and securing the AP with HTTPS, SSH, and unique passwords is essential.
With proper configuration and security hygiene, your Cisco AP can deliver reliable Wi-Fi connectivity and robust network protection.
