    Incomplete logons/redirection.. Driver problem? AV uninstall? Broken update?

    We have numerous different types of laptops from multiple different manufacturers across the building. HP. Lenovo. Toshiba.
    The HP laptops (Probook 6550b and 630's) seem to be encountering connectivity problems. The students can log on fine, it maps their M: (personal, located on the server) drive but consistently doesn't re-map My Documents to the same location. This machines affected are:

    HP 630 with an Atheros AR9285 801.11 b/g/n wireless card.
    HP 6550b Broadcom 43224AG 802.11 a/b/g/draft-n wireless card.
    Other machines of the same specification are not being affected by this.

    The thing is, it's affecting both our images, and even affecting one desktop machine that has a wireless card in it but no desktops that are wired in. So it's not the image and not the platform, and looks not to be the wireless card either!

    The only other thing we can think of is either a broken Windows Update or that we've changed from Symantec to Sophos over the holidays. Previously Symantec has caused problems completely blocking all wireless connections with faulty Teefer2 Miniports, so we know it hooks into the wireless.. Could uninstalling it have broken the drivers on some of them?

    Some Atheros drivers have been extremely problematic, however driver build 10.0.0.234 or later seems solid/reliable. Certainly worth updating.

    Noooo.. I have been misled!

    630's use Atheros. 6550b's (which is the majority of affected machines) use Broadcom 43224AG 802.11 a/b/g/draft-n wireless cards.

    It's looking more and more like a bodged Windows Update or the uninstallation of Symantec is to blame.. Any way to re-name threads?

    A forum mod can rename your discussion.

    Try forcing your APs to G mode instead of dual G/N mode for example. You may also be able to do the same on the Broadcom driver too.

    Done but you can edit the title but going to the advanced mode editor rather than quick edit (when you hit edit post).

    Thank you @ZeroHour
    @Michael - unfortunately having our access points on only one band reproduces these problems by way of an actual incomplete logon. Because all the laptops are 'fighting' each other as it were. However, this isn't the same case (although the symptoms are identical) because when that happens, relogging will solve the issue. The affected laptops always fail. Every time. Regardless of the user, the time logged on, or the current network/WAP load.

    As an experiment, have you tried a mini USB wireless adapter? If this works, it would demonstrate the Broadcom's at fault.

    In theory you can replace the WLAN cards within most notebooks, but you need to check as there are different types and some compatibility issues.

    If it doesn't work, I presume your DHCP scope hasn't run out of addresses or that your notebooks are being allocated a 169 address?

    It's not just Broadcom, the Broadcom's in the 6550b's and the Atheros cards in the 630's are affected. These are the cards that were supplied with them as per HP.

    Hmm. We haven't replaced any WLAN cards because we don't have spares - but it might be interesting to swap a non-working with a working, see what happens.. Although a re-image fixes it (albeit overkill) so I'm inclined to believe it would make no difference - will investigate tomorrow.

    DHCP scope hasn't run out, and they're all using 10.114.192.### addresses as they should. Students can still log on. It just doesn't redirect My Documents to the SAN. Not a huge problem on its own, but considering 'My Documents' is the default saving location and it's redirected, it tells the user that they can't access it 'Due to restrictions placed on this machine by your Administrator', so it becomes a problem. We're informing them of the Computer/M: workaround for now (as M: drive is still mapped correctly to the same location on the SAN) but we're trying to get to the bottom of this so we don't have to reimage everything. It's effected affected 13 machines today alone. 10 6550B's (Broadcom), 2 630's (Atheros) and 1 desktop (Broadcom taken from a 6550b that had had its screen broken)

    Update:
    Definitely not the image. Brand new laptops with a brand new image (and of a completely different brand, these are Lenovo) are now being affected.
    These laptops never had Symantec on them. So it doesn't look like the uninstallation of Symantec is to blame..
