192.168.100.139 router login
To open the admin panel, type 192.168.100.139 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.
192.168.100.139 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.
There is no documented default username and password for 192.168.100.139, and guessing one is a waste of attempts on devices that lock out after a few failures. Check the label on the device's underside or rear panel, where defaults are commonly printed alongside the serial number, then the printed or PDF manual, and finally your ISP's support pages if the equipment was supplied by them.
How to log in to your router
Type 192.168.100.139 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 192.168.100.139, 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 the credentials were changed and are now lost, a factory reset via the recessed button — commonly held for ten to thirty seconds while powered on — restores the label defaults. The cost is everything you configured: port forwarding, static leases, parental controls and firewall rules are wiped, and the Wi-Fi name and password revert to the label values, so every connected device must be rejoined.
192.168.100.139 sits inside 192.168.0.0/16, the RFC 1918 private range reserved for local use. That block holds 65,536 addresses behind netmask 255.255.0.0, and it is the range most people meet in practice because the great majority of home routers, hotspots and small office access points hand out addresses from somewhere within it. Being private space, this address is not routable on the public internet and carries no owner, location or provider: the same number is in use on countless unrelated networks at once.
Its subnet is 192.168.100.0/24, with usable addresses running 192.168.100.1 through 192.168.100.254 and 192.168.100.255 reserved as the broadcast address. Position 139 is well up in the DHCP pool rather than at the low end where gateways usually sit, so on most networks this is a client device — a laptop, printer, camera or media box — not the router itself. People arriving here are typically trying to open a device's admin page or work out what is holding this lease.
No specific vendor is known to ship 192.168.100.139 as a default gateway. If a browser at this address returns a login screen, it belongs to whatever device currently holds the lease, which varies from network to network.

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.
