Hello i installed the openwrt to my modem MR6400 it is a tplink. The firmware is working. But they idea i could not do "opkg update" i am receiving failed to establish connection. Check your network settings and connectivity. This 4g modem can work as 4G modem or as Normal router using port 4 as wan interface.
i found the minimal installation here: https://wiki.openwrt.org/doc/howto/luci.essentials#minimalistic.offline.installation
But i have windows i can't do it.
I tried "vi /etc/config/network" in ssh of the modem, and received the bellow:
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fd5c:0e34:3611::/48'
config interface 'lan'
option type 'bridge'
option ifname 'eth0.1 eth1'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option ifname 'wan'
option proto 'dhcp'
config interface 'wan6'
config interface 'wan6'
option ifname 'wan'
option proto 'dhcpv6'
config switch
option name 'switch0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'switch0'
option vlan '1'
option ports '1 2 3 0t'
How i can install it offline from windows or what i can change to make the router connect to the network through port4/wan. So i wont use the 4g i will connect it to my second router.
