    Is it possible to update from behind a proxy? The "check for updates" button returns "Unable to connect to the Ruckus Wireless Update Server. Verify that you are connected to the Internet, and then try again."

    I can't seem to find anywhere to input the proxy info either...

    I don't think it is, no. I update manually, downloading updates from the Ruckus support site. You may need to speak to your reseller to get an account sorted there.

    We're having exactly the same issues - "Gets to the point where a class of kids using 15 laptops take 10-30 minutes just to log in, and then its virtually impossible to save to network drives etc." - We could have written that ourselves, word for word. Glad it's not just us suffering in a way...

    Also are there roaming profiles involved here? What is the speed of the AP to the switch? Are you tunneling the traffic back to the ZD?

    I think the 1st thing is to upgrade the ZD as suggested.

    Hi Stuart,

    Yes we are running Version 8.2.2.0 build 7 on the ZoneDirector (ZD1000) I've tried the very latest driver and the previous Intel 5100 Driver, same problem.

    I think that it maybe some kind of interference from other Ruckus AP's, but the system is setup to manage any interference/ change channels / power levels etc. Something weird is going on. It's not just from updating to this latest firmware either, we have had problems from previous firmwares and each time an update comes out I install it on our system hoping it will make things better!

    What’s the ideal setup on the actual Intel Card Drivers for the Ruckus systems? I've played around with Power Management and Aggressiveness etc

    Any idea when Firmware 8.3 is due out and what new features we will find?

    Thanks

    Matt

    Matt there will be no 8.3 we should see V9 in the coming weeks which will add features like time based broadcasting and true spectrum analysis at the AP level.

    It sounds like you may have some interference, can you get your hands on a spectrum analyzer? It may be worth disabling back ground scanning mode aswell.
    How many SSID's do you have broadcasting?
    What AP model do you have?
    What is the predominant channel the AP's have chosen? Perhaps some channel management is needed?

    I wouldn’t change the Tx power of the AP’s but may suggest enabling the ability for the AP dynamically change its Tx power if interference is preset.

    Stuart,

    We have 2 SSID's broadcasting, 1 is our Main Access that All Staff use, it's setup with WPA2 PSK Encryption, the other is a Hidden Guest Access SSID, with open access, which nobody is connected to, I set it up for testing out ACL's so users can only access the internet and nothing else.

    We are using the 7962 Access Points and the ZoneDirector 1000. We have 19 Access Points in use and they are spread evently between channels 1, 6 and 11 when I look at the Web Console Dashboard.

    The 5GHZ channels are again spread between Channels:-

    We redirect virtually everything on the kids laptops - start menu, desktop, my docs etc. When working ok this is great, but when we have wireless issues the laptops become unuseable as it can take 5mins to get 2 items deep in the start menu lol. I'll get onto our reseller to see if they have a Ruckus account to get updated firmware. Thanks for all the help so far.

    Matt feel free to take a support info file from the AP and a ZD debug with 802.11, RF managment and Access point enabled.

    I will take a look once i get a chance.

    Hi Stuart,

    I've got the log files all together, all zipped up in a folder along with a copy of the site plan where the access points are placed. What e-mail address can I send them to for you to get at? Do you want to private message me the details.

    Thanks Again,

    Matt

    Hi,

    Just wondering if you managed to solve your problems as we're having similar issues with our Ruckus wireless/student laptops setup. We've been trying to test it a bit this morning with inSSIDer, and we've noticed the Ruckus AP spiking downwards a few times when logging on with a dozen laptops at once to test it (normally we have 32 logging on at once when they're being used with a class). We also noticed that the signal dropped right down when we did Sophos updates on the laptops.

    After reading this thread I'm thinking about turning off as many of the non-Ruckus AP's as we can that we have nearby and see if that makes a difference with our testing - does anyone have any other suggestions that we could try? I found out that net-ctrl do Ruckus wireless when I visited the Bett show on Wednesday and met them at the Edugeek stand - should have seen if they had any ideas whilst I was there!

    Thanks, Peter.

    Hi Peter the sudden spike drop you see from inssider when logging in a bunch of laptops is the AP just under some load and is normal. The was inssider works is by measuring the RSSI and each vendor WNIC will measure this differently. When you see the dip you can be sure the AP is busy working on getting data to clients and not so worried about the beacon strength that inssider uses to measure.

    I would suggest having only Ruckus AP's on in the location as the more wi-fi will create more interference.

    What is the typical roaming profile size? and what radio band are the clients using?

    Thanks

    Hi Stuart,

    Thanks for your reply - I did wonder if it was normal for inssider to behave like that.

    We use mandatory profiles on our network, which are around 3mb in size. The laptops use wireless-N, though they only seem to connect at about 60mbps, so I'm not 100% sure if it's setup properly as I understood N was ment to be upto 300mbps (the AP is in the same room as the laptops).

    We tried turning off some of the non-Ruckus AP's earlier, and we thought it may have made a difference, but we thought it might just be our imagination! Will have to try some more testing on Monday. We only have 6 Ruckus AP's here at the moment, so are still having to use our previous AP's in places.

    Thanks, Peter.

    Did some more testing today (best part of the morning and part of the afternoon trying to figure out what's going on!). Disabled/turned off any non-ruckus AP's in the area that inSSIDer could detect except for a BTHomehub one that appears to be coming from the housing estate next door, but that still didn't seem to make much difference. Takes about 15 minutes to log on 16 laptops (we have 32 normally, but just got out 16 to test with) as a test student and run a program from the start menu, so something is obviously wrong somewhere, just not sure where/what.

    We did notice that the channel of the BTHomehub seems to be channel 1 as detected by inSSIDer, however the ruckus AP has also set itself to channel 1 - could this affect things (I thought that the Ruckus points were supposed to auto-detect/set the channels?).

    Any other ideas? At the moment it isn't really doing what we brought it for... seriously considering seeing if we can either find someone to come in and spend some time with us working out what's wrong with it and/or getting something else instead!

    Thanks, Peter.
