R8000 - DD-WRT WAN IP Issue

In a lot of cases when new configuration has been applied and router has resetted the interfaces - no WAN address! Meaning I need to go and manually reboot both Modem and R8000 and then I am getting WAN. WAN release/renew does not help - still getting zeros. Sometime it's take up to 10min to get WAN, but in some cases - never and I need to reboot the router

The workaound I'm using: Put

The workaound I'm using: Put the code below in the Administration / Commands / Startup section (after putting the desired MAC address in the first line). With this in place I consistently get that same address on reboot, and it can therefore retain the IP assigned by my cable modem.

nvram set wan_hwaddr="xx:xx:xx:xx:xx:xx" ifconfig `nvram get wan_ifname` down
ifconfig `nvram get wan_ifname` hw ether `nvram get wan_hwaddr`
ifconfig `nvram get wan_ifname` up

If you clear your nvram via SSH, it will correct the MAC address problem on the latest Tathagata rev27261

Please follow these full instructions: 

 

Clear out NVRAM: 
**IMPORTANT** This will delete all of your DD-WRT settings to default. 
This is required in order to correct issues from past builds 
(I.E correct the old MAC address issue of 00:00:00:00:00:02, etc) 
**IMPORTANT** The steps below fixed my issues and will also fix your issues if you follow them exactly!
