Routers & Networking	Flip the router over. The label on the bottom has the model, hardware version, default Wi-Fi name, and often the admin login address.

Getting the official Nokia manual

Nokia publishes product documentation on nokia.com. Search there with the full model number from the label, then look for a documents, manuals or downloads section on the product page.

If your model isn't listed, try removing the last few characters, which usually only indicate color or region. For discontinued models, look for an archive or legacy products section, or contact Nokia support directly.
