Re: Chromebook post Spash page logon problem

kevinwalker · ‎03-16-2023

I'd appreciate some suggestions related to the problem below.

When using a Chromebook before the initial operating system login, I'm trying to join a wireless network.

The network is configured with a splash page with AD authentication. The credentials page shows, and I can successfully enter user id and password. After submitting the login I receive a site can not be reached message.

n84.network-auth.com null's dns address could not be found.

An nslookup of n84.network-auth.com resolves and returns a 209.206.63.86.

The work around has been to then reboot the chromebook and login again and we usually have network access.

Thank you

It looks like a Chromebook issue, but I suggest you open a support case.

I am not a Cisco employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

Please, if this post was useful, leave your kudos and mark it as solved.

It sounds like it is having trouble performing a DNS lookup or accessing n84.network-auth.com.

When the user logs in - are they pushed into a new VLAN? If so, perhaps the Chrome book cannot release and renew its IP address for the new VLAN (which is why the reboot solves it).

Is there a firewall that could be blocking the traffic?
