TP-Link Archer C9 Login: Admin Setup Guide
I needed to change the Wi-Fi name on the Archer C9, and the login page…
I needed to change the Wi-Fi name on the Archer C9, and the login page was the only thing in my way. The router had been running for months, and I had not touched its settings since the day it was set up.
This guide gives you the default username and password for the Archer C9, the login address, and the short path I take into the admin panel.
Log in at 192.168.0.1 with the username admin and the password admin.
The fastest way in: tap the button below, then sign in with the details in the box.
IP Address: 192.168.0.1
Username: admin
Password: admin
The button opens our 192.168.0.1 login guide — the direct login button there takes you straight to your router’s sign-in page.
TP-Link Archer C9 Default Login Details
The table below holds the login details as the router ships. I checked them against the setup flow.
These are the factory defaults for the Archer C9. Once you are in, change the admin password to something only you know.
| Detail | Value |
|---|---|
| Login IP | 192.168.0.1 |
| Username | admin |
| Password | admin |
| Admin URL | tplinkwifi.net |
How to Log In to the TP-Link Archer C9
The steps below are the ones I use for the Archer C9. If you get stuck, the TP-Link login guide covers the shared parts of the flow.
- Connect your computer or phone to the Archer C9 with an Ethernet cable or over Wi-Fi.
- Open a browser and go to 192.168.0.1. You can also open tplinkwifi.net, which takes you to the same login page.
- Type admin in the username field and admin in the password field.
- Click Log In. The admin panel opens.
- Once you are in, change the admin password to one only you know, so the factory login is no longer the way in.
Default Username and Password — All Variants
I check the version before I type anything, because the login can change between versions of the same model.
| Version | Username | Password |
|---|---|---|
| Archer C9 v1 | admin | admin |
| Archer C9 v2 | admin | admin |
| Archer C9 v4 | admin | admin |
One note: the Archer C9 v5 uses a different flow — the password is created during setup, not admin.
Change WiFi Password and Network Name
I never leave the factory Wi-Fi password in place. It is printed in the manual, so anyone who reads the manual knows it.
Once you are logged in, here is the path I take:
- Log in at 192.168.0.1 with the username admin and the password admin.
- Open the Wireless settings section of the admin panel.
- Change the network name (SSID) for each band, or leave it as it is.
- Type a new Wi-Fi password, then save the settings.
- Reconnect your devices with the new password.
Use a password of at least 12 characters, with letters and numbers mixed in.
Login Not Working?
I have fixed this login many times, and the cause is almost always small: the wrong network, a mistyped address, or Caps Lock.
If the login page will not open or the password is rejected, work through these fixes:
- Make sure your device is on the Archer C9 network, not on mobile data or another Wi-Fi network.
- Type the address exactly: 192.168.0.1. Try tplinkwifi.net if the IP does not load.
- Try another browser, or clear the cache and try again.
- Check Caps Lock is off, and type the password exactly — passwords are case-sensitive.
- Restart the router: unplug it, wait 30 seconds, and plug it back in.
If you still cannot log in because the password was changed and forgotten, reset the router to factory settings: Press and hold the Reset button for about 10 seconds until the router restarts.
After the reset, log in again with the factory defaults above, and set up the router from scratch.
Key specs: The TP-Link Archer C9 is a WiFi 5 (AC1900) router.
