Ethernet client + Router

apoorvamanjunath

Hello everyone,
I am very much new to this field. and this is the first time I am using omega board.

Currently, I am using omega2S+ and there is no wifi access given to the board yet.

I want Omega to obtain network access through a wired connection and shares network access through its WiFi AP.
May I know the steps to be followed to achieve this.

Thanks in advance.

See the Option2 method under "10/100 WAN Port"(the very last section)in this document:
https://github.com/OnionIoT/Omega2/blob/master/Schematics/Omega2S-Reference-Schematic.pdf

It requires 5x0.01uF capacitors and 4 Resistors.

I tried with Omega2+ and the Expansion Dock (not the SMD version; I don't have one) and was able to connect to the Ethernet Port of another Wifi Router using the TX+, TX-, Rx+ & Rx- pins.

Once physical connection is ok, the Ethernet Port will be active (as seen in the photograph, Port 3 - forget the RPi).

This router is configured for DHCP for Ethernet ports and the eth0 of Omega gets IP address from the router:
[ 1597.684822] rt3050-esw 10110000.esw: link changed 0x00
[ 1599.613398] rt3050-esw 10110000.esw: link changed 0x01
root@Omega-745F:/# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 40:A3:6B:C5:74:60
inet addr:192.168.2.3 Bcast:192.168.2.255 Mask:255.255.255.0

The current routing table of this Omega is:
root@Omega-745F:/# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 apcli0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 apcli0
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 br-wlan

Once you reach these far, next step will be to configure the eth0 as gateway,it would look like
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 <IP.ADD.RE.SS> 0.0.0.0 UG 0 0 0 eth0

You may want to use UCI to reconfigure the Omega, the way you want it.
Please see:
https://openwrt.org/docs/guide-user/base-system/uci
https://wiki.teltonika-networks.com/view/UCI_command_usage

The current config can be viewed using:
root@Omega-745F:/# uci show
dhcp.@dnsmasq[0]=dnsmasq
dhcp.@dnsmasq[0].domainneeded='1'
