Tenda AC18 Login: Router Admin Setup Guide
The first time I set up an AC18, the login page asked for a password…
The first time I set up an AC18, the login page asked for a password and nothing else, and I kept looking for a username box that was not there. I have since learned the AC18 logs in with a password only, so the username stays blank.
This guide gives you the correct defaults for the AC18 and the four steps that will get you into the admin panel.
Log in at 192.168.0.1 — there is no username; the password is blank at first access, and you set it in the setup wizard.
The fastest way in: tap the button below, then sign in with the details in the box.
IP Address: 192.168.0.1
Username: (blank)
Password: (blank at first access — you set the login password in the setup wizard)
Login to Admin Panel →This button opens your router’s own login page. It works only when your device is connected to this router, by WiFi or cable.
Tenda AC18 Default Login Details
I checked these defaults against the AC18 setup flow before I wrote them down, so the table below matches the router you have in front of you.
These are the factory defaults for the AC18: the username is blank, the password is blank at first access — you set the login password in the setup wizard — and the login IP address is 192.168.0.1. Keep the password somewhere safe once you have created it, and set it to something only you know.
| Detail | Value |
|---|---|
| Login IP | 192.168.0.1 |
| Username | (blank) |
| Password | (blank at first access — you set the login password in the setup wizard) |
How to Log In to the Tenda AC18
I walk through this in the same order every time, because the order is what keeps a login from going wrong. If a username field asks for one, leave it blank, and the Tenda login guide covers the AC18 setup flow too.
- Connect your computer or phone to the AC18 with an Ethernet cable or over Wi-Fi.
- Open a browser and go to 192.168.0.1. You can also open tendawifi.com, which takes you to the same login page.
- If this is the first setup, set a login password when the setup wizard asks you to. If you already set one, type it in the password field.
- Click Login. The admin panel opens, and you can change the Wi-Fi name and password, update the firmware, and check who is connected.
Default Username and Password — All Variants
I have seen this catch owners out: the same model can ask for a fixed password on one firmware and ask you to create one on another, so check which case matches your router.
The AC18 has no factory default password. Some third-party sites list admin/admin — that is not the factory default for this model. Check the variant below before resetting the router.
| Version | Username | Password |
|---|---|---|
| Factory default | (blank) | (blank at first access — you set the login password in the setup wizard) |
| admin/admin (wrongly listed) | admin | admin — listed by several aggregator databases, but not the factory default for this model; do not use it. |
| After a password change | (blank) | The password you set is the only one that works — or reset the router to restore the factory state. |
Change WiFi Password and Network Name
I change the Wi-Fi password first on every router I set up, because every device in the house connects with it.
Once you are logged in to the AC18 admin panel, changing the Wi-Fi details takes about a minute.
- Log in at 192.168.0.1 with the login password you set in the setup wizard.
- Open the Wireless settings section of the admin panel.
- Change the network name (SSID) for the 2.4 GHz and 5 GHz bands, 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 a mix of letters and numbers, and avoid reusing a password from another account.
Login Not Working?
I start with the connection itself, because that is where most login failures begin, and I work through the list in the order it is written.
If the login page will not open or the password is rejected, work through these fixes:
- Make sure your device is connected to the AC18 network, not to mobile data or a different Wi-Fi network.
- Type the address exactly: http://192.168.0.1, with no extra letters or spaces. Try tendawifi.com if the IP address does not load.
- Try a different browser, or clear the browser cache and try again.
- Check that Caps Lock is off, and type the password exactly as it is — 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 RST button for about 15 seconds. A factory reset restores the factory defaults — the login password is blank again, and the setup wizard asks you to set a new one.
Key specs: The Tenda AC18 is a WiFi 5 (AC1900) dual-band router.
