192.168.1.40 router login
To open the admin panel, type 192.168.1.40 into your browser's address bar. If the page does not load, this is probably not the gateway address on your network — see the checks below.
192.168.1.40 router passwords
Where to find them:
- The label on the underside or back of the router — most manufacturers print the default admin username, password and Wi-Fi key there.
- The quick-start card or manual that came in the box.
- Your ISP's account portal, if the device was supplied by them — many set a unique password per line rather than a shared default.
No default username and password is recorded for 192.168.1.40, and none should be assumed from the address, since it is a leased client position on an extremely common home subnet rather than a fixed piece of equipment. Where a device at this address asks you to sign in, its defaults are printed on its label or given in its own setup guide or manual.
How to log in to your router
Type 192.168.1.40 into your browser's address bar and press Enter. Type it by hand rather than accepting an autocomplete suggestion, which often fills in a different address you visited before.
If the browser reports that it cannot reach 192.168.1.40, this is not the gateway address on your network. On Windows run ipconfig /all and read the Default Gateway line; on macOS open System Settings, Network, Details, TCP/IP; on Linux run ip route and read the address after "default via".
If the login page loads but rejects your credentials, and you have never changed them, use the defaults printed on the device's label. If they have been changed and nobody knows the new password, a factory reset is the only way back in.
If you do not know the password
If you cannot sign in, identify the device from the router's client list first, then use the manufacturer's own recovery process, which for consumer hardware is often an email-based account reset. Falling back to a factory reset erases all customisation and stored network details, and on anything that hosts its own wireless network the name and password revert to the label defaults.
This address is part of 192.168.0.0/16, the consumer private range covering 65,536 addresses with the netmask 255.255.0.0. It is the space almost all home and small office equipment defaults to, so it is the private range the general public encounters far more than any other.
Zooming in, 192.168.1.40 belongs to 192.168.1.0/24, probably the single most heavily used home subnet in existence. Its usable addresses stretch from 192.168.1.1 to 192.168.1.254, closing with the broadcast address 192.168.1.255. Position 40 places it inside the band where routers hand out DHCP leases, so the device holding it today may hold a different address after a reboot unless a reservation has been configured. Typical reasons for looking it up include identifying an unfamiliar entry in the router's connected-devices list or checking an address seen in a log.

Comment: These addresses are in use by many millions of independently operated networks, which might be as small as a single computer connected to a home gateway, and are automatically configured in hundreds of millions of devices. They are only intended for use within a private context and traffic that needs to cross the Internet will need to use a different, unique address.
