- Open the admin page. Type
http://192.168.15.1into the browser’s address bar (not the search box) and press Enter. - Accept the certificate warning if one appears. Routers use self-signed certificates, so “Not secure” on this page is normal inside your own network.
- Enter the username and password. Look at the sticker on the bottom of the router first: many models print a unique password there. The most common factory pair for this address is
user/user; the full list is in the tables below. - Change the default password in the administration or system section as soon as you are in.

Default credentials work only until someone changes them. If none of these pairs fits, the password was changed; a factory reset restores the default.

What 192.168.15.1 is
192.168.15.1 is the gateway address of the private 192.168.15.0/24 network. Two very different groups of devices use it: the fiber routers that the Brazilian provider Vivo supplies to its customers, and older VoIP routers built for internet phone services.
Vivo Fibra routers (Brazil)
If you are a Vivo customer, 192.168.15.1 is almost certainly your Vivo router. The username is admin, and the password is printed on the sticker on the bottom of the router, next to the Wi-Fi name and key. Vivo routers are made for the provider by several manufacturers, so the page design differs between models, but the address and the sticker stay the same.
The admin password and the Wi-Fi password are two different things. The first protects the router’s settings; the second is what phones and laptops use to join the network.
Older VoIP routers
In our database, 192.168.15.1 is the default of Linksys VoIP routers such as the WRTP54G and WRT54GP2, and of D-Link VWR models — devices that internet phone services such as Vonage shipped to customers. Their logins are in the tables above; the D-Link units use user / user. Many of these routers are locked by the phone service and show only part of their settings.
When 192.168.15.1 does not open
- Your own router is connected behind the Vivo router. Your devices then talk to your router, not to 192.168.15.1. Connect directly to the Vivo router’s Wi-Fi or a LAN port.
- The Vivo router works in bridge mode. In that mode it hands the connection to your own router and its page may be unreachable from the home network.
- Not sure which address your router uses? Check your default gateway.
192.168.15.1: frequently asked questions
What is the password for 192.168.15.1?
On Vivo routers the username is admin and the password is printed on the sticker on the bottom of the router. Older VoIP routers on this address use the pairs listed in the tables above.
Is the Vivo admin password the same as the Wi-Fi password?
No. Both are printed on the sticker, but the admin password opens the router settings, while the Wi-Fi password connects devices to the network.
What if I forgot the changed password?
Hold the Reset button for about 10 seconds with the router on. The router returns to the password on the sticker; on a provider router, the internet settings may need to be restored by the provider.
