I am trying to follow the instruction about how to install openwrt to my asus RT-N56U B1 but the tftp command in the wiki isn't recognized by windows, ( tftp -4 -v -m binary 192.168.1.1 -c put )
So I tried to send the binary with the normal tftp -i command and while it has sent the firmware, the router power led just blink fast after the flashing process, wifi led aren't on and I can't access to the router through ssh.
If you had fast blinking of the power led, most likely Openwrt is installed. And also disabled Wi-Fi tells the same.
Wi-Fi is disabled in Openwrt by default. You should connect with a cable to enable it.
Okay but what do I do? Like I connected my computer to the WAN port of the router and tried to SSH into the router with 192.168.1.1 in order to try to access the config of the router but the connection was denied.
How can I setup my router from there?
Also I have only one ethernet cable, so I can't connect both my modem to router and pc to router at the same time
If the interface in you pc is set to DHCP, then it should get an IP from the router and you'll be able to login into Luci GUI using any browser, or ssh to root@192.168.1.1
