192.168.100.1 usually belongs to the box your internet arrives through, not to the router you connect to. Cable modems from ARRIS, Motorola and NETGEAR show their own pages there, and so do many of the Huawei fibre boxes that providers fit. A Virgin Media hub switched to modem mode moves to it too. If you were looking for your Wi-Fi settings, they are probably on your router at another address.
- Who uses it
- Cable modems (ARRIS SURFboard, Motorola, NETGEAR), Huawei fibre boxes, and Virgin Media hubs in modem mode.
- Username
- admin on the cable modems. Huawei boxes from a provider have their login on the label.
- Password
- Depends on the maker; the table below has each one. Some print a unique password on the label.
- Not the router?
- Your router is the default gateway, usually 192.168.0.1 or 192.168.1.1.
How to log in at 192.168.100.1
- Connect to your network. NETGEAR says a computer cabled to the modem works, and so does one on a Wi-Fi router that is cabled to the modem. Switch off mobile data and any VPN first.
- Type the address. Enter
http://192.168.100.1in the browser’s address bar and press Enter. In a search box it only finds pages like this one. - Sign in. Use the login for your maker from the table below, or the one on the label.
- Set your own password if asked. An ARRIS SURFboard makes you choose a new password at the first login, before its Web Manager opens.
Which devices use 192.168.100.1
These are the makers and providers in our database whose login page is at 192.168.100.1. Each name links to its page, with the login for every model we have confirmed.
Cable modem makers mostly put their routers on another address, which is why ARRIS, Motorola and NETGEAR are missing from the list above: our data files them under 192.168.0.1. Their modems are the ones on 192.168.100.1.
Default login by maker
These come from each maker’s support pages. They work on a modem that is new or has just been reset, and only until someone changes them.
| Device | Username | Password | Worth knowing |
|---|---|---|---|
| NETGEAR cable modems (CM400 to CM3000) | admin | password | The CM2000 has none: each one has its own password on the label. |
| ARRIS SURFboard SB6190 | admin | password | Works once. You must set a new password before the Web Manager opens. |
| Motorola MB8600 | admin | motorola | Both lowercase. There is no password recovery, only a factory reset. |
| Huawei fibre boxes from a provider | Printed on the label of each unit | The label overrides anything you find in a list online. | |
| Virgin Media Hub 3, 4 and 5 in modem mode | None asked | On the label on the base | That is a separate password from the Wi-Fi one. |
Huawei: 192.168.100.1, 192.168.8.1 or 192.168.3.1?
Huawei uses different addresses for different kinds of box. Its fibre terminals, the small boxes where the fibre line ends, answer on 192.168.100.1. Its 4G and 5G routers and pocket Mobile WiFi devices use 192.168.8.1. Its home Wi-Fi routers are on 192.168.3.1 or 192.168.1.1. If a provider supplied the box, the address and password on its label are the ones to use.
Some pages online publish an engineer or “super admin” login for these boxes. That account is your provider’s, not yours, and we do not list it.
192.168.100.1 or the router’s address?
With a separate modem and router you have two login pages. The router is the one your devices talk to, so it is the address shown as the default gateway, and it holds the Wi-Fi name, the Wi-Fi password and almost everything else. The modem sits behind it at 192.168.100.1. Our 192.168.1.1 and 192.168.0.1 guides cover the router side, including how to find the gateway on each kind of device.
Other common router addresses
Your router itself is most likely on one of these. Addresses with a guide of their own are linked.
| Address | Typically | Used by, in our data |
|---|---|---|
192.168.1.1 | The most common address | Linksys, ZyXEL, DrayTek, Westell, Vodafone, PLDT, Converge, TalkTalk and 39 more |
192.168.0.1 | The second most common | NETGEAR, D-Link, TP-Link, Tenda, Sky, Virgin Media, NOW Broadband, Spectrum and 13 more |
192.168.1.254 | Many ISP hubs and gateways | Billion, 2Wire, Netopia, GIGABYTE, BT, EE, Plusnet, AT&T and 6 more |
192.168.2.1 | Belkin and some Canadian providers | Belkin, Edimax, SMC, Deutsche Telekom, Bell, Virgin Plus |
10.0.0.1 | Cable gateways from large ISPs | Xfinity, Rogers, Videotron |
192.168.8.1 | 4G and 5G home routers | DITO, Three, Zong |
192.168.50.1 | Current ASUS routers | ASUS |
192.168.100.1 | Fibre boxes and cable modems | Huawei, ubee, EchoLife |
192.168.l00.1 and other typing mistakes
All four parts are numbers. 192.168.l00.1, with a letter l, and 192.168.1oo.1, with two letter o’s, both look right and go nowhere. 192.168.100 on its own is missing the last part. And 192.168.1.100 is a different address altogether, often one a router gives to a phone or laptop.
It still will not open
- The box is a router, not a modem. An all-in-one hub from your provider keeps its pages on its gateway address, not on 192.168.100.1. A Virgin Media hub only moves there in modem mode.
- A guest network. Guest Wi-Fi is usually kept away from settings pages (what a guest network can reach). Join the main network or use a cable.
- A VPN or private relay. These route the request away from your home network. Turn them off for a minute.
For the rest, see why the router page will not load when the internet works fine.
Questions people ask
Do I need to log in to my modem?
Usually not. NETGEAR says its cable modems work without anyone logging in, and that the page only lets you change a limited number of settings.
Will a factory reset change my internet settings?
On a cable modem it puts the login back to the default, so the table above applies again. On a Motorola MB8600 a reset is the only way back in once the password is lost. On a box your provider configured, ask them before resetting it, because they may have to set it up again.
Is 192.168.100.1 safe to open?
Yes. It is a private address inside your own network, so the page comes from your own modem. Nobody outside your home can reach your 192.168.100.1.
