Wireless problems driving me mad
Our wireless system is playing up and I can't get to the bottom of it. We have hp procurve 420s all round the school - old but usually pretty solid. Recently network connection has been dropping out in the school hall - usually windows shows the wireless connection at full strength, but with no Internet connection. To me, this pointed towards a network issue between the AP and the DNS, but I haven't even been able to identify which AP is causing the problem. I have been using angry ip to check what I'm connected to, but when I've had connectivity problems I've sometimes seen dozens of results and sometimes seen none. I was expecting (hoping) to see one ip address in the results, thus identifying the AP.
When I run tracert to the DNS gateway, I don't see any intermediate steps. What tool should I use to try and track this down. I've looked at Wireshark, Netstress and Netsurveyor, but tbh I've got some learning to do and I'd be grateful for some hints on what direction I take before I dive in.
I'm also having a problem with a particular teacher's laptop. It connects perfectly in the staff room (where there is an AP), but not in her classroom. Same model of ap with same firmware and security. The curriculum laptops connect reliably in her classroom. All suggestions welcome (it's not preventing her from working, as there's a proper LAN point at her desk, but I would like to know why it's not working)
Thanks for listening :)
