192.168.0.1 or 192.168.1.1: Same Job, Different Subnet

What the third number tells you

An IPv4 address is four numbers called octets. Home routers almost always pair their address with the subnet mask 255.255.255.0, also written /24. With that mask, the first three octets name the network and the last one names the device. So 192.168.1.1 is device 1 on network 192.168.1, and 192.168.0.1 is device 1 on a different network, 192.168.0.

Each of those networks has 256 addresses, and 254 of them can go to devices:

• .0 is the network address, which no device uses.
• .1 to .254 are usable host addresses. The router normally takes .1.
• .255 is the broadcast address, used to reach every device at once.

A laptop on 192.168.0.x treats 192.168.1.1 as a machine on some other network. Instead of talking to it directly, the laptop hands the request to its own gateway, so a router set to 192.168.1.1 on the same cable never answers.

Both ranges come from the same private block. RFC 1918 sets aside 192.168.0.0/16, which holds 65,536 addresses, room for 256 separate /24 home networks. It also reserves 10.0.0.0/8 and 172.16.0.0/12, which is why some gateways sit at addresses like 10.0.0.1. None of these can be reached from the public internet.

192.168.1.1 and 192.168.0.1 side by side

Makers and providers that start on 192.168.0.1

These defaults come from each company's own support pages. Models change, so the label on your unit has the final word.

• TP-Link: TP-Link's login FAQ gives tplinkwifi.net or 192.168.0.1 as the default address and suggests trying 192.168.1.1 if those don't load.
• D-Link: D-Link's router login help uses http://192.168.0.1 or http://dlinkrouter.local.
• Tenda: Tenda's sign-in guide lists http://tendawifi.com or 192.168.0.1.
• Cox: Cox's support site and community point Panoramic Wifi gateway owners to 192.168.0.1 for the gateway's admin tool.
• Virgin Media (UK): Virgin Media's Hub help names 192.168.0.1 as the Hub address. In Modem Mode, where your own router takes over, the Hub answers at 192.168.100.1 instead.

For brands that ship on 192.168.1.1, see our list of routers that ship on 192.168.1.1. Mesh systems such as eero and Google Nest Wifi use other ranges again.

Speed and security are a tie

Neither address is better. Both are private /24 networks with the same 254 device slots, and your internet speed depends on your plan and your hardware, not the third octet.

Moving a router from 192.168.1.1 to 192.168.0.1, or to something unusual, adds almost no protection. Anyone already on your Wi-Fi can read the new gateway in seconds, and nobody outside can reach either address. A strong admin password and current firmware do the real work, so change the address only to fix an actual conflict.

Checking which range your network uses

You don't have to sign in to anything to find out. Any of these works:

• Your own device's address. If your phone or laptop shows 192.168.0.23, you're on the 0.x network. 192.168.1.23 means 1.x.
• The router label. Most stickers print the default login address, and sometimes a hostname such as tplinkwifi.net.
• The gateway field. The Router or Default Gateway entry on your device is the router's current address. Our gateway lookup for every device shows where it lives on Windows, Mac, phones, Linux and Chromebooks.

The label only shows the factory default. If someone changed the address later, trust the gateway field on your device.

Modem and router on the same range

The difference starts to matter when two boxes claim the same network. Say your ISP's modem-router uses 192.168.1.1 and you plug your own router into it. Your router's WAN (internet) port gets a 192.168.1.x address from the ISP box, while its LAN side also wants to be 192.168.1.1. It can't route between two identical networks, so the internet drops or the admin page opens the wrong box.

Some routers sort this out on their own, which is why a router's IP can seem to change by itself. When a TP-Link router sees its WAN and LAN sides on the same subnet, it moves its own LAN address, typically between 192.168.0.1 and 192.168.1.1, so traffic keeps flowing. Nothing is broken. Look up the new gateway on your device and use that.

Double NAT, and how to get rid of it

Double NAT means your traffic passes through two routers that each translate addresses: the ISP gateway and your own router. Browsing still works, but anything that needs incoming connections struggles, because the outer box knows nothing about the inner one's port rules.

Typical signs:

• An Xbox reports Double NAT detected in its network settings, and consoles show a Strict or Moderate NAT type.
• Port forwards you set on your own router do nothing.
• Online games, voice chat and remote camera apps connect poorly.

Ways to fix it:

• Put the ISP box in bridge mode, so it acts as a plain modem. Virgin Media calls this Modem Mode.
• Use IP passthrough where it's offered. On AT&T gateways, IP Passthrough hands one device, your router, the gateway's public address.
• Or leave the ISP box as the only router and switch your own router to access point mode.

While you're sorting this out, you may bump into 192.168.100.1. On many cable modems, and on some satellite dishes, that address opens the modem or dish status page rather than a full router admin page.

VPNs, cameras and access points

Remote networks that use your range

A VPN into an office, or into another home, breaks in a confusing way when both ends use 192.168.1.0/24. Your laptop treats the remote printer's address as local and never sends the traffic through the tunnel. If you run your own VPN, give your home network a less common range, such as 192.168.37.x, rather than 0.x or 1.x, which huge numbers of home routers already use.

Cameras and recorders set to the other range

Some IP cameras ship with a fixed address in 192.168.1.x. Hikvision documents 192.168.1.64 as its cameras' default, and many Dahua devices start at 192.168.1.108. On a 192.168.0.x network you can't reach them until the ranges match. Use the maker's setup tool (Hikvision's is called SADP) to change the camera's address, or give a PC a temporary static address in the camera's range, make the change, then set the PC back to automatic. Newer cameras often take an address from DHCP instead.

A second router as an access point

A router running in access point mode needs a LAN address inside the main router's subnet, for example 192.168.0.2 when the main router is 192.168.0.1. Turn off its DHCP server so only the main router hands out addresses, and give it an address outside the main router's DHCP pool.

Moving a router from 192.168.0.1 to 192.168.1.1 (or back)

1. Sign in to the router at its current address, ideally from a computer on a cable.
2. Open the LAN settings. TP-Link's LAN IP guide uses Advanced > Network > LAN, and many D-Link models use Setup > Network Settings (D-Link's steps).
3. Enter the new address, for example 192.168.1.1, and keep the mask at 255.255.255.0. Make sure no other device already uses it.
4. Check the DHCP pool. Many routers move it to the new range automatically. If yours doesn't, set it to match, such as 192.168.1.100 to 192.168.1.199.
5. Save. The router applies the change and usually restarts, so your connection drops for a minute or two.
6. Reconnect, or run ipconfig /renew on Windows, then open the new address in your browser.

Then update everything that relied on the old range: DHCP reservations, port forwards, printers, NAS drives and cameras with static addresses, and your bookmarks. A phone browser can make the change too. Expect the phone to fall off Wi-Fi while the router restarts, and reconnect before you open the new address.

Can't connect after the change

If the new address won't open, your device is probably still holding its old lease, pointing at a gateway that no longer exists. Turn Wi-Fi off and on, unplug and replug the cable, or run ipconfig /release followed by ipconfig /renew.

A device that won't reconnect at all may have a static IP from the old range. Switch it back to automatic, or give it an address in the new range.
