Troubleshooting a RADIUS wireless lan
I'm currently covering for absent technical staff at one of our associated academies. Amongst other things, they are having a lot of problems with their wireless network, which the principal has asked me to look at while I'm there, as their current technical staff are a little out of their depth with the complexity of the system (by their own admission)
The system is a RADIUS enabled wireless network, using PEAP-MSCHAP v2 authentication and WPA encryption. It works, but it only works after a user has logged on via a cabled link, it will not let users log on wirelessly. As you can imagine this is a little bit of a problem.
We have an engineer from the company who support the systems in the school visiting tomorrow, unfortunitely this is a different company to the one that installed the system. I understand this is not the first time they have visited and So far they have been un-able to get the system to work correctly. Apprently it did work up until July time when as far as I can work out the certificate expired on the clients, which messed the whole thing up. This part was fixed, but it's never worked properly since then according to the people I've spoken to.
Because the support company have had more than one attempt at fixing this, I'm not holding out a lot of hope of them fixing it this time, so I'm hoping I can gather some information from fellow edugeekers to help me guide the engineer if they don't seem to be getting anywhere. I've never worked with a wireless network using 802.11x authentication before, although I do understand the principles behind it, so any helpful suggestions or comments appreciated, so I can at least help the engineer tomorrow if they are struggling.
