192.168.100.39 router login
To open the admin panel, type 192.168.100.39 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.
192.168.100.39 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 pair is documented for 192.168.100.39, and none should be assumed. A private address identifies a position on a network rather than a product, so credentials belong to whatever device happens to hold it. Look on the unit's own label or sticker, which on many current devices carries a unique per-unit password rather than a shared factory default, then check the quick-start guide, the manufacturer's support pages for that exact model, or the documentation supplied with ISP-provided equipment. Generic credential lists are frequently wrong for a given unit, and repeated failed attempts can lock the interface.
How to log in to your router
Type 192.168.100.39 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 192.168.100.39, 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 are genuinely lost, a factory reset is the usual recovery route, and it is not free. A reset commonly clears the Wi-Fi network name and key, port forwards, static DHCP reservations, VLAN and firewall rules, DNS settings and any PPPoE or ISP account details, so the device has to be reconfigured from scratch; ISP-supplied equipment sometimes needs re-provisioning by the provider. Since no vendor is known for this address, follow the reset procedure documented for the device you actually have, which on many units means a recessed button held for several seconds while powered on. Export a configuration backup first if the interface is still reachable.
192.168.100.39 is a private IPv4 address inside 192.168.0.0/16, the block RFC 1918 sets aside for private use alongside 10.0.0.0/8 and 172.16.0.0/12. With a 255.255.0.0 netmask the block holds 65,536 addresses, none of them routable across the public internet. That has a practical consequence: the address has no owner, no registrant, no ISP and no geographic location. Any network may reuse it, and countless networks do so simultaneously, so the only context that gives it meaning is the local network you are querying it from.
Within that block the address sits in 192.168.100.0/24, whose usable range runs from 192.168.100.1 to 192.168.100.254, with 192.168.100.255 reserved for broadcast. It is host 39 of that subnet, above the first few addresses routers typically claim for themselves and in a position that commonly falls inside a DHCP pool. An address here often belongs to a client or a statically assigned host rather than to the gateway. No specific vendor is known to ship 192.168.100.39 as a default gateway address.
Most people looking this address up have typed it into a browser expecting a login page, or found it listed in a router's connected-devices table, an ARP cache or a log file. Confirming which device actually holds it, using ipconfig, ip route or the router's DHCP lease list, is usually the quickest next step.

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.
