Four steps, with help at each one if something doesn't work.
-
Join the Wi-Fi network of your Pentagram router, or plug a network cable into one of its LAN ports. You don't need internet access for this, only a connection to the router itself.
On a phone, turn off mobile data while you set things up, and switch off any VPN.
Can't find the network?
The Wi-Fi name (SSID) and its password are printed on a sticker on the bottom or back of the router.
If the router is new, plug it in and wait two minutes for its lights to settle before connecting.
-
Type it in the address bar, not in a search box. Search engines can't reach your router.
The page won't load
Router addresses are numbers only. 192.168.l.l and 192.168.o.1 use letters and end up in a search engine instead.
Use http://, not https://, and try a private window if an old page is cached.
Your router may use a different address. Find it:
- Press Windows + R, type cmd and press Enter.
- Type ipconfig and press Enter.
- Read the number next to "Default Gateway".
- Open System Settings › Network.
- Select your Wi-Fi, then click Details.
- Open the TCP/IP tab and read "Router".
- Open Settings › Wi-Fi.
- Tap the ⓘ next to your network.
- Read the number next to "Router".
- Open Settings › Network & internet › Internet.
- Tap the gear next to your Wi-Fi network.
- Open Advanced and read "Gateway".
- Username adminPassword admin
Newer routers ship with a unique password printed on a sticker underneath, so check there before trying the defaults.
The password doesn't work
Try the other common pairs: admin / admin, admin / password, admin with an empty password, or user / user.
Routers from an internet provider often use a password printed on the label, not a standard one.
As a last resort, hold the recessed Reset button with a paperclip for 10–15 seconds. That erases every setting, including your Wi-Fi name and password, so you'll set the router up from scratch.

Can't find these settings?
Menu names differ by brand. Admin password sits under System, Administration or Management. Wi-Fi security sits under Wireless or WLAN.
Write the new passwords down somewhere safe before you save them.
