OpenWRT: Software update wget returns "Network is unreachable"

Question

I have OpenWRT [Barrier Breaker 14.07 / LuCI Trunk (0.12+svn-r10530)] installed on a TP-Link Wifi Extender (TL-WA850RE v1), though acting like a simple Access Point, DHCP & DNS are provided by a LAN Ethernet port.

When I try to Update Lists from System > Software, OpenWRT returns:

wget: can't connect to remote host (78.24.191.177): Network is unreachable
wget: can't connect to remote host (78.24.191.177): Network is unreachable

I've searched for some kind of solution but I'm probably searching this up all wrong.

Do you have any pointers on what to do?

Thanks

Solution

It seems like your Access Point can't connect to the internet, as there is no default gateway configured.
For now, you can just run this, in order to connect temporarily:

route add default gw 192.168.1.1 eth0

For later, set 192.168.1.1 as your default gateway in the network config.

I assume 192.168.1.1 is your router IP, if not, change it according.

Connect it to the Internet?

[yagmoth555]

OpenWRT in the enterprise??

[acseven]

@MichaelHampton All devices connected to the router have internet access.

[acseven]

@yagmoth555 I'm sorry but I don't understand your comment/question.

[Damiano Verzulli]

@acseven: please post the output of "ifconfig" and "netstat -rn". If you're unable to connect to your openwrt via ssh (you can use "putty" for this), you can provide us the screenshot of "status=> routes" and "network=>intefaces"

[acseven]

Hi @DamianoVerzulli, I've inserted that info on the original question. Thanks!

[acseven]

Hi, thanks for the repky. I get this error though: root@OpenWrtTPLinkExtender:~# route add default gw 192.168.1.254 eth0 route: SIOCADDRT: No such process

[davidbaumann]

route add default gw 192.168.1.1 br-lan

[acseven]

Thanks - I had to point to my DNS server, as that error kept popping up when using what is actually the gateway (192.168.1.254).
