First Login
Telnet
Default, dropbear (SSH service) doesn’t accept any connections at firstlogin, we can use telnet to connect to router via default IP address:
telnet 192.168.1.1
passwd
exit
After we set a password for OpenWRT, telnet deamon will be disabled. We can
login again with ssh ssh root@192.168.1.1
LuCI
Open your browser and connect to the router at its default address (usually 192.168.1.1). Login using username root with an empty password.
Then click on the menu in the top bar on Administration -> System. A page to change the password is displayed.
Network
Network configuration is located in the file /etc/config/network. We can determine the configurations including VLAN, interfaces, routing in this file.
After editing, we need to excute the following command
/etc/init.d/network reload
to reload the network without reboot router.
Internet Connection
We connect to Internet via a device (bridged function) over Ethernet cable, means we log in to the ISP through a DSL modem or fiber converter has been set up. In this case, we use PPPOE to connect to the Internet.
Install packages for PPPOE connecting
opkg update
opkg install ppp kmod-pppoe ppp-mod-pppoe
We can edit manually or use UCI command line to config connection information
uci set network.wan.proto=pppoe
uci set network.wan.username='username_from_isp'
uci set network.wan.password='password'
uci commit network
Check file /etc/init.d/network if it has following section:
config 'interface' 'wan'
option 'proto' 'pppoe'
option 'username' 'username_from_isp'
option 'password' 'password'
then reload network.
