I just got a G34 Surfboard modem today. I had xfinity assist me on setup. I had mistankenally given them the WAN MAC address for activation. I was able to get to the modem to work but it had given me a local address of 169.xxx.xxx I corrected MAC this with xfinity but, still can not get anything but, a local IP address of 169. Because of this I can not asses the web admin page.
I am using a Mac running Sonoma. I tired reseting my network, followed by a restart. This did not work to resolve this issue. I had tried reset of all caches as well with no success as well.
