    Limited or no connection error?

    Clutching at straws really prior to investigation - have had a few laptops come up with a 'limited or no connection' error, but even when relocating them to our own individual AP the error persists, and will not connect to the wi-fi. Re-imaging does the trick, and that's an easy way out, but it's an incident management solution and not a problem management one.

    Aruba wi-fi, Toshiba laptops, can be any laptop at any time - no predictors, no pattern.

    Waiting for the next one to do the same so's I can investigate a bit more, but meanwhile...any thoughts?

    Cheers.

    Can other laptops connect to the AP fine?
    If others can connect to the AP, how many are connected?
    Not something silly like running out of DHCP addresses?
    What happens if you try a ipconfig /release and /renew?
    Any updates for the drivers or firmware update for the AP?

    If you disable and then re-enable the NIC does that help?

    What happens if you try a ipconfig /release and /renew? [next thing on my list to try]
    Any updates for the drivers or firmware update for the AP? [firmware all current]

    Thanks for these suggestions anyway.

    Can you ping the NIC locally on the laptop?
    Do you get a 169.XXX.XXX.XX address if you do ipconfig?
    What happens if you disconnect from the wireless network completely and forget all the security details and then rejoin and enter the security details.

    Yeah done that, thanks. Nothing in the logs. It's as if the wi-fi and the laptops think they have a connection, and the network standards seem to be in place and working, but it's just locking out progression of the full log on and staying that way. Odd.

    How up to date are your wireless drivers?

    Admittedly some of them will be part of a 2009 image, but others are from last summer - and this was actually seen a couple of times when those drivers were current. It will have to be considered if all else fails.

    Cheers.

    What happens if you disable the hardware on the laptop and then re-enable it? This could save you re-imaging it until you find the root cause.
