Employment Transition Experiences IT & Tech Careers.This is all a hunch for now, obviously, but just something else to look into. Perhaps each DHCP scope can have different options configured and the two aren't quite the same allowing for this break? You said it works fine in one VLAN even on a Mac computer but not another. It seems Apple computers are doing this now.īackground lesson aside, I would look at your DHCP server config to make sure it can accept this. Windows devices don't seem to implement this by default. Using a client ID instead of MAC means either network card will get the same IP address, allowing you to switch from wired to wireless and vice versa at will without it affecting your connections.
Traditionally wired and wireless in the same host. This is to help facilitate situations where you may have multiple network cards on the same computer. This new method of using a Client ID is in accordance with RFC 4361 which you can read in all its glory at I see this happening more and more, specifically with Linux devices and have seen a few Android devices in the wild as well doing the same thing. Instead of seeing a MAC address such as 9C:B6:D0:61:11:B5 as you might be accustomed to, you might see a unique ID such as c9c42987333b45b699836968bc00d2af instead. Slowly, there is a move to start using unique client IDs instead of MAC addresses. Is your DHCP service, SonicWall, setup to be able to deal with DHCP Client IDs? Traditionally, a DHCP client (ie your computer) would send its MAC address as the client ID and would show up in your DHCP lease list as such. Move those files somewhere safe and Restart. You could also try to reset the network settings: If all of that seems to be correct, maybe it's time for a PRAM reset: If you go to the Advanced page for the adapter is there manually entered DNS/Search Domain settings? What is the status for the network adapter? Wifi is a separate VLAN than Wired, I know DHCP is being issued I can plug my laptop into each port that's not issuing DHCP to macs and My windows laptop will pull dhcp everytime so I know the VLAN is configured correctly, and the DHCP server is working.Īre the network interfaces even giving an APIPA address? Yes interfaces are enabled and set to DHCP on the iMACs, they pick up wifi dhcp no problem just not wired.
