10.1.1.1 — Router Admin Login
10.1.1.1 sits in the same private 10.0.0.0/8 block as 10.0.0.1 but is chosen by a different set of vendors. Telstra Smart Modems in Australia, Billion routers, some Cisco and Aruba business gear and a number of carrier gateways all answer here.

Quick answer
Connect to the gateway and open http://10.1.1.1. Telstra Smart Modems use admin with the password printed on the base of the unit. Billion routers generally accept admin / admin. Business hardware on this address usually has credentials set during commissioning rather than a published default.
Which routers use 10.1.1.1
This address is more common on carrier and business equipment than on retail consumer routers.
| Brand | Typical models | Username | Password |
|---|---|---|---|
| Telstra | Smart Modem Gen 1, 2 and 3 | admin | On the base of the unit |
| Billion | BiPAC routers on the 10.x range | admin | admin |
| NetComm | Selected NF and NL models | admin | admin |
| Cisco | Small business RV series (configured) | cisco | cisco |
| Aruba | Instant On and IAP clusters | admin | On the label |
| Sagemcom | Carrier-branded gateways | admin | On the label |
| Technicolor | Some carrier fibre units | admin | On the label |
The label on your own unit always overrides this table. For every other brand, see the full credential reference.
How to log in at 10.1.1.1
Carrier hardware on this address is often partially locked, so expect some pages to be visible but not editable.
- 01
Connect to the gateway itself
Use its Wi-Fi or a LAN port. If a second router sits behind it, make sure you are attached to the gateway rather than the downstream device, or you will be on the wrong subnet entirely.
- 02
Open the address
Type
http://10.1.1.1. Do not confuse it with 10.1.10.1, which is a different address used by other hardware, or with 10.0.0.1, which Comcast and Cisco favour. - 03
Accept the certificate warning
Standard for local devices with no publicly trusted certificate. Advanced, then proceed, on your own equipment only.
- 04
Find the credentials on the unit
Telstra Smart Modems print an admin password on the base. Billion and NetComm units generally use admin and admin. Cisco RV hardware ships with cisco for both fields but forces a change on first login.
- 05
Expect some settings to be read-only
Carrier firmware routinely locks DNS, firmware updates, remote management and sometimes the VoIP configuration. This is intentional, survives a factory reset, and is not a fault.
Carrier gateways and what you actually control
The 10.0.0.0/8 block is enormous — over sixteen million addresses — which is why carriers and businesses favour it. Choosing 10.1.1.1 rather than 10.0.0.1 leaves the whole 10.0.x.x range free for other purposes, and gives a network room to grow into separate subnets without renumbering.
On consumer lines, the most likely thing behind this address is an ISP-supplied gateway, and that comes with a specific set of expectations. You can normally change the Wi-Fi name and password, view connected devices, set up port forwarding and configure a guest network. You frequently cannot change DNS servers, downgrade firmware, disable the provider remote management channel or alter VoIP settings, because the carrier needs those to remain predictable for support and for phone service.
If you want full control, the usual answer is to place the gateway in bridge or modem-only mode and run your own router behind it. That gives you every setting on the downstream device, at the cost of losing whatever telephony or IPTV features the gateway was providing. Check what you would lose before committing, because on some carriers voice service depends on the gateway routing.
One genuinely useful thing on Telstra hardware specifically: the Smart Modem includes a mobile backup connection that takes over during a fixed-line outage. Its status is visible in this panel, and knowing whether the unit has fallen back to cellular explains a lot of otherwise mysterious slow-network complaints.
Business hardware on this address, particularly Cisco and Aruba, was almost certainly commissioned by somebody with a documented configuration. Before resetting anything, find out whether that documentation exists. A reset on managed equipment can take down more than one network.
When 10.1.1.1 will not open
The address does not respond
Confirm you are connected to the gateway and not to a router behind it. Read the real value with ipconfig or your phone Wi-Fi details before trying other addresses.
admin and admin are rejected
Carrier units use a unique password printed on the unit, usually on the base or beside the serial number. Cisco RV hardware forces a password change at first login, so the factory pair stops working immediately.
Settings appear but cannot be saved
Carrier firmware locks those pages. A factory reset does not unlock them. Bridge mode plus your own router is the route to full control.
The connection is slow with no obvious cause
On a Telstra Smart Modem, check whether the mobile backup connection has taken over from the fixed line. The status is shown in this panel.
I reset a business gateway and lost the network
Managed hardware carries a commissioned configuration that a reset erases. Restore from whatever backup or documentation exists, or contact whoever installed it.

Common questions about 10.1.1.1
What is the default password for 10.1.1.1?
It depends on the hardware. Telstra Smart Modems use admin with a unique password printed on the base of the unit. Billion and NetComm routers generally use admin and admin. Cisco RV hardware ships with cisco for both fields and forces a change at first login.
Is 10.1.1.1 the same as 10.0.0.1?
No. Both sit in the private 10.0.0.0/8 range but they are different addresses used by different manufacturers. Comcast and Cisco favour 10.0.0.1; Telstra and Billion favour 10.1.1.1.
Why can I not change my DNS servers?
Carrier firmware locks DNS, firmware and remote management so that support can rely on a known configuration. This is intentional and survives a factory reset.
How do I get full control of my network?
Put the ISP gateway into bridge or modem-only mode and run your own router behind it. Check first whether that removes VoIP or IPTV services that depend on the gateway routing.
What is mobile backup on a Telstra Smart Modem?
A cellular connection that takes over automatically when the fixed line fails. Its status appears in this panel, and a modem sitting on backup explains slower than usual performance.
Should I factory reset a business gateway?
Not without knowing whether a documented configuration exists. On managed hardware a reset can take down more than one network and the settings are rarely recoverable from memory.
Not the address you needed?
