I'm trying to use static IP for the Omega2, last firmware 0.2.0 (b194).
All works fine, except DNS setting.

This is my /etc/config/network file config:

config interface 'wwan'
        option ifname 'apcli0'
        option proto 'static'
        option hostname 'Omega'
        option ipaddr '192.168.1.95'
        option netmask '255.255.255.0'
        option gateway '192.168.1.1'
        option dns '8.8.8.8'

After network config restart with command /etc/init.d/network restart, I try to ping to google with:

root@Omega # ping google.com
 ping: bad address 'google.com'

It can't resolve hostnames with static IP configuration. If I use DHCP config, no problem.

My ifconfig output:

apcli0    Link encap:Ethernet  HWaddr 40:A3:6B:C1:44:0E
          inet addr:192.168.1.95  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::42a3:6bff:fec1:440e/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Anybody use static IP? Can share configuration files?.

Thanks in advance!

i work in DHCP but with a static lease with the MAC Address of apcli0 (xxxxx0E for you but not the MAC Address of the Omega Label )

my router is a Mikrotik and this system work for all IOT (ESP 8266 / ESP 32 / 4Duino ...)

Bye

Hi, It's no apply in this case, because I'm finding a solution without modify router setup.

Maybe the dnsmasq program interferes? What does /etc/resolv.conf say?

Maybe... I try all configurations in /etc/config/network and /etc/config/dhcp, but it doesn't work.

File /etc/resolv.conf is modified by dnsmasq after boot.

Output of route -n command with DHCP (default device config):

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

With STATIC IP config:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 apcli0
192.168.3.0     0.0.0.0         255.255.255.0   U     0      0        0 br-wlan

So, I route manually with command:
# route add default gw 192.168.1.1

And voila, ping google.com works...

Complete config for static IP

Device IP address 192.168.1.95 and router/gateway in 192.168.1.1.

Modify interface 'wwan' in file /etc/config/network as follow:

config interface 'wwan'
        option ifname 'apcli0'
        option proto 'static'
        option hostname 'Omega-XXXX'
        option ipaddr '192.168.1.95'
        option netmask '255.255.255.0'
        option gateway '192.168.1.1'
        option dns '8.8.8.8'

If you use the Access Point (example a phone connected to Omega as Wi-Fi client) add DNS servers to /etc/dnsmasq.conf file:

# Use public DNS servers for Access Point when
# static IP is used for 'wwan' interface.

server=8.8.8.8
server=8.8.4.4

Add these commands to /etc/rc.local to update config on next boot:

# ----------------------------------------------------------
# COMMANDS FOR STATIC IP CONFIG
# ----------------------------------------------------------

# Add routing table (need it for STATIC IP config)
route add default gw 192.168.1.1

# Restart Dnsmasq for update DNS servers (only Access Point)
/etc/init.d/dnsmasq restart

Next, reboot Omega.

Check if the route -n has a similar output:

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
192.168.3.0     0.0.0.0         255.255.255.0   U     0      0        0 br-wlan

And ofcourse, try ping google.com command.

Conclusion

In my humilde opinion there are a config bug for static IP, maybe Onion would fix it.

route add default gw 192.168.1.1

I tried that solution but I noticed that the Gateway configuration dissapears when the wifi disconnects from an AP.

Has anyone found a better solution?
