Connect your computer to any LAN ports of your router, or connect to its wireless network. Make sure the router is working.
You have not specified what OS you have installed on your computer, so I assume Windows. If it is anything else please refer to OS documentation on how to complete the steps below.
Obtain LAN configuration
If you remember what IP-address was configured on router's
Network → LAN web administration settings page, proceed to next step.
Factory defaults are: IP address =
192.168.0.1, subnet mask =
255.255.255.0 - try those before anything else.
If you do not remember what was configured, you have three options:
- Factory-reset the router
- Use your router vendor's utility to find router's IP-address
Try to find its IP-address in ARP cache like this:
Write down MAC-address that is printed on the bottom of the router. It should be a hexadecimal number like
Open command prompt (On Unix-like OS this is called a terminal emulator) by pressing Windows+R, typing
cmd, and hitting ENTER key.
arp -a and hit ENTER. This commands displays ARP MAC-to-IP table like this:
Internet Address Physical Address Type
192.168.168.2 00-98-76-54-32-10 dynamic
192.168.168.3 00-AB-CD-EF-01-23 dynamic
- Try finding the MAC-address you wrote down in the "physical address" column, router's IP-address should be in "Internet address" column.
If your MAC-address is not listed you could try following:
- Disconnect you computer from all networks except the one connected directly to your router.
- Assign a static IPv4-address to your computer that does not belong to any local network. Something like
18.104.22.168 should do. Subnet mask should be
0.0.0.0, no default gateway or DNS-servers. This ensures we are actually sending data to correct network.
- Flush ARP cache by typing following command in command prompt:
arp -d -a (on Linux:
sudo ip -s -s neigh flush all) and hit ENTER. Rebooting your computer also works.
- Now we need to broadcast any data to everything on the physical network. To do that input command
ping 255.255.255.255 -n 1 and hit ENTER. The command should be unable to receive any respose - that is normal.
- Input command
arp -a and hit ENTER. Examine results once again.
If nothing works, you may want need to resort to guessing IP-address.
192.168.1.100 are the common ones.
Manually assign IP-address
- Your router does not support obtaining its LAN network address from a DHCP server. To be able to access the router without hassle, configure your DHCP server to reserve any IPv4 address within your network for the router. Your router will never actually query the server, but the server should not assign this address to any other device.
- Assign a static IPv4-address to your computer that belongs to same network as the router. Simply add 1 to last octet of router's IP address, so if your router's IP address is
192.168.123.1 configure your computer to use
192.168.123.2. If you do not know the network mask, try
0.0.0.0. Leave default gateway and DNS-address fields blank.
- Open a web-browser and browse to your router's IP-address. You should be able to login into its web-administration panel. If connection fails, you probably guessed it's IP address incorrectly.
- Use the web administration panel (Network → LAN) to configure a your router's static address to previously reserved one. Save settings and reboot your router.
- Revert your computer's network configuration to obtain IP-address from DHCP server again.
- You should now be able to log onto your router's web administration panel by connecting to IP-address you reserved without re-configuring your computer to do so .
