Switch WAN type from SSH

[CntrlAltDel]

Hi there,

I seem to be struggling trying to get WAN type changes applied through SSH. So far for example I've tried:

nvram set wan_proto=pppoe
nvram set pppoe_username='x'
nvram set pppoe_passwd='x'
nvram commit
service restart_wan

But no dice. WAN configs dont change whatsoever in the web gui and if I check with the below I find that DHCP is still set.

nvram show | grep wan_proto

I would like to be able to switch to PPPoE and also to DHCP.

Given the number of wan variables available in nvram, I can't say I'm surprised. You're making assumptions that it's just a matter of nvram variables, when such changes might trigger other processes. It might even require a reboot.

Regardless, in a case like this, I always dump nvram both before and after the change and diff the results, just to be sure what actually changed.

DIR='/jffs'
nvram show | sort >/dev/null > $DIR/nvram.before
# make changes via GUI
nvram show | sort >/dev/null > $DIR/nvram.after
diff $DIR/nvram.before $DIR/nvram.after

I used /jffs rather than /tmp in case it requires a reboot after making changes.
