Default username and password for 192.168.15.1
I have seen this done wrong more than once, so I keep it simple here.

I treat this as a quick check, not a deep setting.
Vivo customers can also change WiFi settings in the Vivo app, under the internet section of the account. This works even when you are away from home.
192.168.15.1 not working? Try these fixes
I would rather confirm it now than fix it later.
1. Check your connection
Your device must be connected to the router’s WiFi or plugged in with a cable. Turn off mobile data on phones, because the router page cannot be reached over a cellular connection.
2. Type the address correctly
Type http://192.168.15.1 in the address bar, not the search box. Use only numbers and dots. Do not add www or .com. Our IP Address Checker fixes common typos.
3. Confirm the router IP
Your router may use a different address. Use the Router IP Finder to read the exact Default Gateway from your device.
4. Try another browser or a private window
Clear the browser cache or open a private window. Some browsers force HTTPS, so type http:// at the start.
5. Restart the router
Unplug the router for 30 seconds, plug it back in, wait two minutes and try again.
6. Turn off VPN or proxy apps
A VPN sends your traffic to another network, so your local router cannot be reached until you disconnect it.
How to change your WiFi name and password
I always start with the router page for this.
- Log in at http://192.168.15.1 with the admin username and password.
- Open Wireless, WiFi or WLAN settings. On dual-band routers, edit both the 2.4 GHz and 5 GHz networks.
- Change the SSID to set a new WiFi name.
- Choose WPA2-PSK (AES) or WPA3 security and enter a new password. Our WiFi Password Generator creates a strong one.
- Click Save or Apply, then reconnect your devices with the new password.
How to reset the router to factory settings
In my experience, this is the part that trips most people up.
If you forgot the admin password, a factory reset brings back the default login.
Find the small Reset hole on the back of the router, press it with a pin for about 10 seconds while the router is on, and release it when the lights blink. After it restarts, log in at http://192.168.15.1 with the default details.
Note: a reset erases your WiFi name, password, port forwarding and any internet provider settings. Keep your provider login details handy before you reset.
