A guest wireless client is visiting with a work laptop. Can anyone tell me what these 86U log entries indicate:

Code:

It means that device is configured with the erg.com domain, so it tries to request it when obtaining a lease. Since that domain doesn't belong to your router, it's ignoring it.

This is probably a (poorly configured) business laptop that's configured for the domain used by their company (and which ignores best practices by using a public TLD on a private network).

Informative, thanks!

@OzarkEdge - For years, I had the same log entry, a few times per day, while my own business laptop was connected to the router.

I already had a reserved/manually assigned IP within the DHCP range for my laptop, but I was finally able to stop that log entry by also adding a Hostname, which is an optional field.

I hope this helps!

My work laptop has always triggered this on my relatively new AX86U and I would never had known if this thread wasn’t revived. Very good to know.
