latest builds unconditionally assigns 192.168.1.1 to eth0 regardless of network configuration settings

[johnc60@…]

On the latest builds (of Atheros, at least) the IP address for interface eth0 is unconditionally set to 192.168.1.1/24 despite having a valid user defined network configuration. IP addressing should use the network configuration file except for failsafe mode. This was working correctly in previous builds (r15888 and 8.09.1) and is broken in the current trunk and in 8.09.2.

This defect renders the router unusable because the LAN side is unreachable.

In the following example, IP address 192.168.1.230 should be assigned to interface br-lan. However, on interface eth0, the IP address of 192.168.1.1 is also assigned. This double assignment is also reflected in the routing table. The network config file is also included.

I had this in #6074, however it's working now, so I'm wondering if it's an intermittent uci-defaults bug (this is in trunk)

[jow]

Shouldn't this be fixed by ​/changeset/17597.html ?

I'm have the same issue with todays trunk. Im compiling for Routerstation Pro. ( assigns 192.168.1.1 to eth0 regardless)

[anonymous]

Ended up disabling image configuration for now

[cshore]

This has been working for some time. Need a new report if it shows up again.
