Wireless connection has dropped access to the network

[winng]

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?

What happens if you give a laptop a static address on the network?

I suspect they're not able to contact your DHCP server, which would suggest that if you gave them a static in your range they wouldn't be able to contact your DCs unless they're resolvable from outside your LAN. Check the range that the APs are connecting to, perhaps try them on different ports that are definitely on the default VLAN.

Against the wireless adapter?

Against the wireless adapter?

Yes. What was the reasoning for removing the VLANS? You now have a massive flat network that contains all devices? Seems like a backward step to me. I'm assuming you've modified your dhcp scopes to reflect the new setup?

Yes, we changed Internet provider which meant going on to their WAN and restricted our IP addresses. So by flattening the network and removing all but the default VLAN, devices (other than static IP servers, printers, etc,) picked up a new address from the newly defined scope.

 

It was all working okay until the wireless stopped seeing the DHCP (or so it appears).

Is the wifi managed by an on-site controller?

[lostsoul]

You say smoothwall was doing radius, was it just wireless clients authenticating against that? are you still using radius? Can you quickly set up a PSK on you wireless controller to rule that out? Edited November 16, 2016 by lostsoul

I don't know how to do that....
