We've recently experience major changes to our network including endeavouring to remove all VLANS, excepting the default vlan1.
We previously used a smoothwall box as radius but this is powered off now as we go out via a lightspeed box in the cloud.
It's been okay for a week or so but now the laptops have lost their connection to the network, such that the signal is still okay but users are unable to connect to their network shared areas nor the internet.
When checking their wireless network adapter it reports a local 169... or 192... IP address which is not given out by DHCP.
If the user connects via an ethernet cable normal service is resumed however, this is not okay as not all teaching spaces have data ports, let alon be in the right location.
I don;t where to check why this is happening. Any ideas please?
