My Linksys EA7300 v2, which previously worked with a DSL modem with the following settings, now will not boot with the new Cable ISP modem.

? Should have default DHCP WAN settings
My DSL was ancient (4.5Mbps down) and I switched to Cable w/ a refurbished Motorola MB7240.
In stark contrast to my old DSL modem, the new Cable modem has no configurable settings. I started with a fresh 21.02.1 OpenWRT install after flashing the OEM firmware over itself.
I think it flashed but the router appears to attempt 3 boot cycles before falling back and successfully booting the OEM firmware.
My forum search found this post regarding failed OpenWRT installs in the same device IP range 10.xxx.xxx.xxx.
yes i put these three lines in /etc/rc.local .Previously it used to revert back to orginal fw.I am not sure what it does but this can be done only after installing openwrt. So if it got installed ,then main part is already done. You will have to manually assign ip address if your main router is not in 192 range. Mine was 10.1 range and so manually had to add it to get LUCI webpages...and also to install packages.
The Cable modem interface says "IP": 10.103.140.51 but the MAC does not match my EA7300. I see nothing in the Linksys OEM user interface as to what WAN DHCP address was assigned. The "Trouble Shooting" interface says Internet Address 184.108.40.206 which reverse DNS look up says belongs to Spectrum
I previously has set /etc/rc.local to
/rom/sbin/mtd unlock s_env /rom/sbin/mtd erase s_env exit 0
Is this a known issue? Short of buying a Modem/Router combo and subneting to the EA7300, is there a work around? I think I can get back into OpenWRT using the old DSL modem.
