Wireless Problems - Intel & Ruckus

[mattpant]

Hi Guys,

 

We have a Ruckus managed wireless network in place, We have 1 x ZD1000 with 20 x ZF7962 Access Points.

 

We also have a number of NEC Network Projectors installed in the Classrooms (NEC NP901W). I'm having a number of teachers telling me that they often get "disconnected" from the projector, when this happens a message pops up on the projector saying "An Error in the Network Occured" and the screen just displays the last image sent, until it reconnects, this can be anything from a few seconds to 10-15 Minutes.

 

I think the problem lies with the Ruckus Wireless and the staff machines loosing connection so the software can no longer talk to the projector, I've looked in Event Viewer on the machines and I notice alot of the following:-

 

Source - TCPIP

Event - 4201

The system detected that network adapter Intel®...Link 5100 AGN - Packet Scheduler Miniport was connected to the network, and has initiated normal operation over the network adapter.

 

The drivers for the Intel WiFi are the latest from the Intel Website (13.1.1.1), and our firmware on the Ruckus Wireless is again the latest from the Ruckus Website (Version 8.2.1.0 build 21)

 

I don't really know where I should start now...

 

Any ideas, help or tips.

 

The client doesn't appear to be loosing a connection to the network, although it may be so quick or short that we don't notice and it's just enought to disconnect the projectors.

 

We are using PSK-WPA2 security on our AP's

 

Thanks

Hi Matt are you able to post any logs from the ZD?

 

Have a look at the client logs at the time the disconnect happens.

 

Thanks Stuart

Thanks Stuart,

 

I've set the log file now to "Show More" so will keep an eye out for what crops up. I had heard that this was a "known issue" and was something to do possibly with a Windows Update and the Intel WiFi cards, they can't make up there mind if they should be on 2.4GHz or 5GHz, the last Ruckus Firmware update should have fixed the issue, but it hasn't.

 

Cheers
