A forgotten router admin password is separate from a lost Wi-Fi password. Recovery options depend on what was configured before lockout.
Before you change anything
This is a diagnostic entry point. The source supports the general check, not a confirmed root cause for your device.
What to check first
What default gateway address does a device on the router network show?
Record the exact model, hardware revision, firmware and recent change before adjusting settings. If you cannot answer the question, keep the cause open.
Narrow the likely path
| Observation | Next check |
|---|---|
| Login name fails | Use the actual default gateway IP while connected to the router LAN. |
| Page opens, credentials fail | Distinguish admin credentials from the Wi-Fi passphrase and use the vendor recovery path. |
| Reset considered | Save settings and ISP/service details first; reset is a recovery step, not an address lookup. |
Decision after the first test
Check the model's documented recovery method before a reset. Save ISP details and the current network name if a factory reset becomes necessary.
Use a documented next step
Verify before escalating
After each change, repeat the exact failed task. If the result is unchanged, restore the previous setting and use the official support link for your exact hardware revision. Don’t assume a menu or capability from a related model.
