I can't get my wan/modem to connect with my openwrtOne

Installing and Using OpenWrt
1

Hi. My setup was an ISP router, ISP modem 10gEpon connected to the fiber optic cable from my wall.

Bought a openwrt one, reflashed it, put luci on it and connected it to my modem and pc, all in the correct ports.

I check the interface tab and my wan is red, i can't get an IP. My ISP doesn't have vlan ID and uses DHCP.

So I tried changing the IP address of my br-lan which is green (in case the modem has the same 192.168.1.1 ) it didn't work

I spoofed the Mac of eth0 which is the wan device, to the wan mac of my original router and it doesn't work.

I also tried all combinations of turning this off and this on and letting it power cycle. I'm out of ideas
Pls halp

Many ISPs lock onto the WAN MAC (respectively the dhcp_default_duid) of your router and don't like when it changes. In many cases it helps to power off the modem/ ONT for a while (10 minutes, an hour, my ISP needs longer than that), before switching everything and the new router back on.

I left it off for like 4 hours same thing ...

In that case more details will be necessary (ISP, old router's config, OO's config would be a start).

Comcast/Xfinity
How do I see old routers config, I once wanted to access their dash on the local IP and it told me to go over the fking Xfinity app. Which I don't have.
What OO?

I even spoofed the duid using the Mac address it had, if it would use duid type 3 not the one with the timestamp. That's at least what ai suggested me. Changed the request prefix and this what someone on /g/ suggested

config interface 'wan'
option proto 'dhcp'
option device 'eth0'

config interface 'wan6'
option proto 'dhcpv6'
option device 'eth0'
option reqaddress 'try'
option reqprefix '56'
option norelease '1'

Basically already was in this setting except for the prefix and noreleaee (which I didn't add it's not an option on luci)

SOLVED

i have Cumcast
The fiber optic modems come as one with their router, not even spoofing the mac helps. Went to customer support and in store, found out that their caux is compatible with 3rd party modems, but not fiber optic ones.

Isp won't take any other fiber optic modems and pretty much impossible to spoof. At&t on the other hand allows it.
Bridge mode it is.
