    Well - looks good but I'm relucant to do a full chicken count yet!

    No reports of open file connections being lost - some reports of the class folders not being available at startup (I run a statrtup script that maps P: drive to a shared class folder at startup so this might be due to slow network connections - I'm going to try and simulate this one as its easy to check jsut by switching them all on at the same time)

    @James - have you tried the new ones yet - have they helped you?

    regards

    Well - there's still something not right

    I was in at the school all day yesterday using the netbooks to timelapse record the Year3/4s buliding a viking longboat.

    All went well in the morning - everything working but in the afternoon I really struggled to copy 500MB size files from the netbooks to the server - would fall over half way through - ended up using a pendrive

    Im def going to have to rig up a Buffalo AP and try that out.

    Hopefully, the large file transfer failure is repeatable.


    regards

    Simon have you tried running a speed on the ZD after it failed?

    Sorry Stuart - my brains obviuosly got worse over Easter

    (BTW I didn't do anything when it failed on me - I had 1 hour to get the videos off the netbooks and onto my pendrive before they closed the school on me )

    a speed TEST from the ZD
    How do you do a speed test with the ZD?

    regards

    Under Monitor - Currently Active Clients find the client you wish to test and hit the speed dial icon (orange) far left of the client info.

    A new window will appear.
    Hit Start.
    Hit Ok on the popup box.
    Select MAC Intel or Windows.
    Run the SpeedFlex.exe and hit start again.

    Ta for info - I'll certainly give it a go when next in - as I said - i hope the large file transfer failure is repeatable as it'll give us something real to get a grip on

    Have you check if there is a power save setting defined in the drive? This can cause problems.

    The settings on these Realteks is very sparse.

    Got
    802.11d - Disable/Enable - Disabled
    Beacon Interval - 100
    PSPXlinkMode - Disable/Enable - Disabled
    Wireless Mode 802.11b/802.11b/g 802b/g/n - set to 80211b/g/n

    and thats it
    From earlier in the thread

    If you bring the wireless controller up in the device manager you can access the power saving option in the 'Power Management' tab. Maybe this is what nicholab is referring to.

    I'm not sure Windows would cut the power to the wireless card when it was connected to a network though, even if it wasn't 'in use'. Could be that it's just reducing power to the point it falls out of range though?

    HTH

    I was mighty relieved to come across this thread last week as it echoed exactly the same issues I am having with 60 new N130's. Intermittant wireless dropouts resulting in pupils unable to save work to a server at the end - and during - a session of use. To cut a long story short, I have applied the latest driver issued by Samsung for the Realtek Wireless device on one of the PC's and await developments at the school. Even that wasn't without extra work, I like to set up wireless networks with a Hidden SSID, this had worked perfectly with the original driver, but the updated driver was having none of it. I have now 'unhidden' my SSID in order for this new driver to work - rest assured I still have WPA security in place, I was worried that I may have to 'loosen' that a little but fortunately not.

    Simon - I see no new posts since 8th April - how have things gone for you since then???

    I will be updating the driver on a few more of the N130's next week and keeping my fingers firmly crossed.

    Thanks to all, Martin

    Ok - reluctantly maybe its time to say the issue has been fixed!

    (Awaits the wrath of the IT Gods vengance)

    No-one (apart from me and my large file transfers (which I've not been able to repeat) ) has mentioned any problems (apart from the odd random ones you get)

    I might even re-enable the security


    regards

    Simon
    PS Stuart - if you read this - close the ticket

    I'm sorry for re-opening this case, but what did you finally do for fixing the problem? I've read all post of five pages and still not sure what you did... We've got just the same problem with 100 Toshiba netbooks, and I think that i've tried everything... Thanks in advance!

    Ancient history for me now I'm afraid ,just lived with the issues and as the ruckus APS die I replace them with unifi as my controller is no longer spotted supported
    I didn't have a good experience with them
