Router login
See what your router knows
Network Weather can sign in to some routers to see more than it can from the outside: connected devices, access points and switch ports, and router settings that affect your WiFi. Signing in is optional. Everything else in the app works without it.
What you get without signing in
With no password at all, the app identifies your router from the outside:
- MAC vendor lookup names the brand of the router's network card (Ubiquiti, Netgear, ASUS, TP-Link and so on).
- Reverse DNS of the router's address sometimes gives a model hint (for example
UDM-Pro.local). - HTTP and HTTPS fingerprinting reads the router's web page title, server header and certificate to narrow down the model.
- SSDP and UPnP discovery asks the router for its manufacturer, model and firmware.
- UPnP IGD reads the internet-side address, connection status and link speed, when the router offers it.
Most home routers answer these without a password. You don't have to do anything.
Which routers you can sign in to
| Brand | How you sign in | What it adds |
|---|---|---|
| UniFi (Ubiquiti) | Your router's local admin username and password, then a code if your account uses two-step verification | Connected clients, access points, switch ports and router settings for the scan to check |
| eero | Your eero account's email address or phone number, then the code eero sends you | Your eero network's details, read from eero's cloud (eero has no local sign-in) |
The router row also appears for some other brands (ASUS, Netgear, TP-Link, Linksys, MikroTik, D-Link, Actiontec), but signing in to them is not supported yet: the app tells you so and does not try your password, so it cannot lock you out. Everything the app learns without signing in still works for every brand.
How to sign in
- Open Network Weather and go to the Status tab.
- Click your router (the Gateway step on the map). If your router supports signing in, its detail panel shows a row named after the brand, with a Sign in button.
- Click Sign in. A window titled Sign in to your router's brand opens.
- Enter what the table above asks for, and click Sign in (for eero, Send code, then enter the code).
- When it works, the row says Signed in.
For UniFi, use a local admin account on the router, not your Ubiquiti cloud account, unless you have set the router to accept cloud credentials locally. The sign-in window says the same.
If the window says Sign-in isn't available, the app can't sign in to that router yet. Click Got it; the app keeps monitoring the router without a password.
Where your password is kept
Your password is encrypted with the Windows Data Protection API (DPAPI), which ties it to your Windows user account, and stored under your user's registry at HKEY_CURRENT_USER\Software\NetworkWeather\Gateways, one entry per router. It stays on your PC: the app sends it only to your router itself, to sign in, and never to Network Weather.
Signing out and removing a saved password
Click Sign out on the router row, then Sign out again to confirm. That ends the app's session with your router, and the app stops reading from it.
Signing out does not delete your password: it stays saved on this PC, encrypted to your Windows account, and still goes only to your router. To sign in again, click Sign in and type your password; the sign-in window does not fill it in for you. There is no button to delete a saved password yet. To remove it, quit Network Weather and delete your router's entry under HKEY_CURRENT_USER\Software\NetworkWeather\Gateways in Registry Editor.
Troubleshooting
Sign-in fails with the right password. Some routers allow one admin session at a time. Close the router's web page in your browser and try again.
The router row doesn't appear. Make sure you are on your home network, not a VPN or a phone hotspot. The row appears only when the app recognises a router it knows how to talk to.
UniFi asks for a code every time. That is expected if your account uses two-step verification: the app asks for a fresh code at each sign-in and does not keep codes.
