192.168.1.100: What It Means and How to Find It
192.168.1.100 is usually a device address, not a router. What it means, how to find the device and how to reach your router at 192.168.1.1.
- Connect to the router’s WiFi or plug in a cable.
- Open http://192.168.1.100 in your browser.
- Sign in, then change the default password.
I have typed 192.168.1.100 into a browser and wondered why no login page showed up. It looks like a router address, but it often belongs to a device on your network instead.
That one mix-up costs people a lot of time. This guide explains what 192.168.1.100 really is, how to tell, and which address opens your router instead.
192.168.1.100 is usually a device on your network, not your router login page.
How to open the device at 192.168.1.100
In my experience, this is the part that trips most people up.
- Make sure you are on the same network as the device.
- Type http://192.168.1.100 in a browser.
- If a printer, camera or NAS page opens, sign in with the login from that device’s manual or label.
- If nothing opens, the address belongs to a phone or computer, which has no web page.
Which routers use 192.168.1.100?
I have seen this done wrong more than once, so I keep it simple here.
- The first or an early address in the DHCP range of many routers, so the first device to connect often gets it
- Network printers and IP cameras with this as a factory default
- Access points and NAS drives set to a fixed address by an administrator
- Some routers set their DHCP pool to start at .100

Want your router’s login page?
I treat this as a quick check, not a deep setting.
The router is usually 192.168.1.1. If not, read the Default Gateway on your device with our Router IP Finder.
192.168.1.100 not working? Try these fixes
I would rather confirm it now than fix it later.
1. Check your connection
Your device must be connected to the router’s WiFi or plugged in with a cable. Turn off mobile data on phones, because the router page cannot be reached over a cellular connection.
2. Type the address correctly
Type http://192.168.1.100 in the address bar, not the search box. Use only numbers and dots. Do not add www or .com. Our IP Address Checker fixes common typos.
3. Confirm the router IP
Your router may use a different address. Use the Router IP Finder to read the exact Default Gateway from your device.
4. Try another browser or a private window
Clear the browser cache or open a private window. Some browsers force HTTPS, so type http:// at the start.
5. Restart the router
Unplug the router for 30 seconds, plug it back in, wait two minutes and try again.
6. Turn off VPN or proxy apps
A VPN sends your traffic to another network, so your local router cannot be reached until you disconnect it.
What usually lives at 192.168.1.100
I always start with the router page for this.
On routers that use the 192.168.1.x range, DHCP often starts at 192.168.1.100. The first device that joins your network picks it up, so it could be anything: a laptop, a phone, a smart TV or an IP camera.
A few network cameras and printers also use 192.168.1.100 as their own factory default when there’s no router to give them an address. If you’re setting up one of those directly with a cable, that’s why it shows here.
Reserve 192.168.1.100 for one device
In my experience, this is the part that trips most people up.
- Log in to your router, usually at 192.168.1.1.
- Open DHCP or LAN settings and find address reservation.
- Select the device or type its MAC address.
- Enter 192.168.1.100 as the reserved IP and save.
- Restart the device.
Reserving addresses for cameras, printers and NAS boxes saves you from hunting for them every time the router restarts.
Device at 192.168.1.100 keeps disappearing
I have seen this done wrong more than once, so I keep it simple here.
If a camera or printer at this address works for a while and then vanishes, it’s probably getting a new IP after a restart. Set a reservation as above.
If two devices both claim 192.168.1.100, one was given a static IP by hand. Set it back to automatic and let the router manage addresses.
