IBM ThinkPad T42 would not connect to my home network secure wireless

Configuration IP of Windows __An internal error has occurred: a device attached to the system is not functioning. __Please contact support services technical microsoft for more help.

Others have had a similar problem, but I tried the solutions that have worked for them, without success.

All of a sudden, my IBM ThinkPad T42 wouldn't connect to my home network (WPA2-PSK) secure wireless.  It would be either (1) stay in a constant state of "acquiring network address" or (2) do not recognize networks wireless in the range.  Sometimes, it would connect to a nearby unsecured network, but the network would still not appear in the list of available wireless networks.  So I tried to connect directly to the ethernet, which also did not work.  I then ran the ipconfig/all command at the command prompt and got the message:

Windows IP configuration
An internal error has occurred: a device attached to the system is not functioning.
Contact support services technical microsoft for more help.
Additional information: unknown media status code.

So, I went to Microsoft Product Support Services, which does not seem to offer all the solutions.  I searched this error online and found several similar problems - some users had problems with viruses.  Some users had winsock2 corruption, and some recommended to reinstall the drivers for my network cards.  I'm computer literate, but not a computer Wizard, so I was able to follow their instructions for checking the winsock2 corruption (I think), and I think it's very good.  I did a complete scan of symantec, but who came with nothing.  I downloaded the drivers for my network cards which are: Wireless - 11 a/b/g Wireless LAN Mini PCI Adapter, ethernet - connection of a Mobile Intel (r) PRO/1000 MT and was able to update my wireless driver, but not the driver ethernet.  The latter Assistant said we "could not find a better match for your hardware than the software currently installed".  I had wireless internet to work for a few hours last night, even if I still have the same error message when I run ipconfig/all.  I started my computer this morning, and the same problem again - constantly says "address of network acquisition" even if no wireless networks are appearing on the list.  Also, I tried the system restore to see if I could go back before the problem started, but after that I tried several dates, System Restore has still not successful - it wouldn't work again.

So now, I have my computer in safe mode, and it is connected to the wireless internet, even if the ipconfig/all command still gives the same message, and I am running symantec again to see if I can find something!

Please help me!  If you think that I may have missed something with the winsock2 or installing drivers, or if there is something I could not find on the internet, please let me know!  I'll try anything.

Note: I have Windows XP Professional Service Pack 3.
Network card drivers, I'm running are:
Wireless: Date - 02/05/2007, Version 4.1.2.156, provider - Atheros
Ethernet: Date - 24/10/2006, Version 8.7.9.0, provider - Intel

Thank you!

Update: when I disable the Intel PRO/1000 MT driver, I can run ipconfig/all with success.  Then imagine it's something to do with this adapter or the driver.  Any ideas?

OK, so here is what I did to solve this problem.

I've updated to the latest version of the IBM BIOS

Then get the WLAN driver from the manufacturer, NOT IBM, NOT Windows Update. Depending on your card, it will be Cisco or Intel.

I can not stress enough that updates to IBM and Windows update does not work and I lost a lot of time. However, once downloaded directly from the manufacturer (new version) worked flawlessly!

    Hello

    I had a problem with my laptop. The laptop does not connect to my home network.

    I found the wireless network, but when I hit enter after entering the password (), suddenly a pop up come that said "Windows could not connect to the network". The laptop connects well with portable hotspot in my phone (3 G Tethering). But my phone (Samsung Galaxy Pocket) connects to the home network.

    Dlink DSL-2730u (secure wifi with WEP 128 bit key)

    Please solve my problem...

    Original title: problems with my Acer laptop

    Guess - encryption levels are the same. E.g. is your set of router that you use WEP only but your PC configured to use WPA only? http://Windows.Microsoft.com/en-HK/Windows7/set-up-a-security-key-for-a-wireless-network

    If this is the case try to configure WPA2 or WPA rather than fall to WEP.

    Check all the other related settings as well. knowledge is the router using MAC filtering, are there available IP address so that it can allocate? (some routers are possible to limit the amount of IP address, they can allocate at one time).

    Second, if it does not remove the encryption all and see if it connects then. JUST AS a TEST, do not leave it.

  • WiFi does not connect to the home network

    IM currently problems with my wifi on my new z3 compact network.

    My compact z3 is able to find the wifi network & shows an excellent signal, I get the password to try to connect but just z3 keeps alternating between safe, secured with wpa/wpa2 & getting ip address...

    I tried to reset the router, phone that allowed me to use wifi, but a day later I'm back to the problem off z3 does not connect to wifi. All other devices connect without any problem at all.

    Any help would be appreciated & ty in advance.

    Do you know if there is no limit on the number of devices that you can connect to your ISP network and the internet? Also make sure that DHCP is enabled in your network and you do not have any MAC-filter in the network.
    Alternatively, you can try to manually specify an IP address that can be used in your network in the phone. Tap and hold the network, select Modify network, then check Show advanced options and set a static address.

  • I can not connect computer vista laptop to my network home, but I can connect to other networks. Other computers can connect to my home network very well. This can be corrected?

    My laptop runs Vista and I've not had problems connecting to my home network wireless until a week ago or not.  Then, trying to connect, I see other available networks, but not my own.  When I try to connect manually, it says that the network already exists.  Other computers, macbooks, are able to connect to my home network without problem.  I am able to connect to a network on my laptop fine unsecured wireless.

    I could 'solve' the problem or get reconnected with a restoration of the system to an earlier date, but it only lasts a day or two.  I searched for another fix and tried many things, including to reset the router, remove my network, and then reinstall, etc, but can't seem to get this to work as if it were - automatic connection as the first network.

  • HP Pavilion dv6t-7000: Ralink RT5390R wireless adapter does not connect to 802.11n network

    I have a HP Pavilion dv6t-7000, equipped with the Ralink RT5390R wireless adapter.  For the life of me, I can't get it to connect to my home network when implemented as 802.11n.  They connect other devices. If I change my router 802.11 g, but no other change, doe HP connect. But if I return the router to 802.11n, HP sees the network, and it correctly identifies as a 802.11n network, but does not connect.

    The router is a D - Link DIR-615 (N300 2.4 ghz)

    Woo-Hoo.

  • HP Deskjet 3055 A does not connect to the WIFI with security

    I'm trying to configure a Deskjet 3055 A on my DD - WRT router.  I am a highly qualified network engineer, so I don't know 100% what I'm doing.

    First, DD - WRT supports WPS connection, because these are very precarious.  This means that my only way to connect the pritner to my home network is to connect to my PC and use the Setup utility (downloaded from your page drivers) I use the 28.8 version.

    My router supports the 2.4 and 5 GHz and I know the printer is only 2.4 GHz.  I disabled completely the 5 GHz network in order to connect the printer, even though it shouldn't have any effect.

    I restarted my router and reset the printers wireless network using its integrated control panel.

    In any case, after a shameful 2 hours troubleshooting, I did discover that the printer WILL NOT CONNECT to the WIFI network if any security is applied against it.  It works 100% fine with open security however, it is totally unacceptable.

    I tried both WPA Personal and WPA2 Personal, both with the same effect.

    For reasons to try, I added also the printer to my network WIFI open and tried to manually change the setting WIFI via webinterface of printers, however, whenever I try and access the wireless configuration wizard, I simply get an error message saying "Internal system error" - eventually I managed to work around this another bug that has been there for years (see http://h30434.www3.hp.com/t5/Printer-Networking-and-Wireless/Internal-System-Error-prevents-access-t...

    After installing printers web interface WIFI, the problem is always the same and it does not connect.

    HP, we were in the order of 2500 of these printers for users of our remote site.  If you don't come to the top with a quick solution/bug fixed, consider the lost business!

    Concerning

    Ian

    After playing well, I managed to find a solution for this!

    For all users who are unable to find a solution by using the other methods, here's what to do.

    Change your local network to open the safe but note your WIFI settings for your default installation.

    Connect the printer to the open network the HP software (via USB cable)

    Go to the URL of the printer, but make sure that you connect through HTTPS - if you get an internal system error, keep refreshing until it works (WHAT A JOKE!)

    Click on 'Network', then click 'Advanced' on the left.

    Enter the network settings as they need to be secured.

    Downstairs, check "in an infrastructure network, use 802. 11b / g behavior (assuming that your assisted supports g, otherwise use the b only option), then click on apply.

    Turn on your wireless security, on your router and then the printer should connect!

    I am really confused as to why this is not automatically enabled, if the printer is not working with security on a Wireless N network wireless, then have this as the default!

    HP - feel free to thank me in this post!

  • Tecra A10 - refurbished - cannot get it connected to my home network

    I just got this Tecra A10-104 refurbished Laptop... before I take this back I ask here in case where theres something I missed as I am unable to get it connected to my home network.

    I use a Belkin wireless router that has 2 main (LAN) directly connected PC and another PC connected wireless.
    It's my router: http://www.belkin.com/uk/support/article/?lid=enu&pid=F5D8233uk4&aid=9238&scid=0

    All PC connected and fine work.
    Now I'm setting up this laptop to connect.

    I uninstalled the Vista Business and ussed the product recovery disc that came with the Tecra XP Pro.

    Is my wireless card: Intel (r) Wireless WiFi Link 5100 (pilot Date: 27/04/2008 - the driver Version: 12.0.0.73)

    He sees the network, but no matter what I try just does not connect.

    What I've done so far (read before suggesting things I've already tried):

    Reconfigured routers WPS to the shared key system.

    Ensured that the wireless adapter's parameters defined at 20 / 40 Hz (automatic)

    Restarted the router, cable modem & laptop several times

    Laptop wireless button is turned on.

    FN + F8 to activate BLUETOOTH WIFI (ON) (OFF)

    Wireless network added to settings Auto Connect with the end SSID and password encryption method.

    Click on connect when network appear in the revamped network and Password Viewer dialog.

    Does not.

    I would add that the laptop has no problem connecting via its Gigabit LAN port.

    Something else I'm missing?

    Thanks in advance.

    EDIT: Double post deleted.

    UPDATE:

    The next thing I tried was to reinstall Vista Professional recovery disk to see if it has suffered from the same problem.

    Wireless has worked under Vista, and despite the updates I was offered, worked without having to update all the drivers.

    This got me thinking... so the question is probably DRIVER XP related.
    What I've done now is to back up all the updates driver told me to download TEMPRO (BIOS & Manager wireless updates included).

    I think part of the problem is that only TEMPRO works under Vista (not XP) so you are not informed of any updates may be required if you upgrade to XP directly after the purchase (which is what I did).

  • Windows cannot connect to the home network

    Hello

    My laptop can't connect to my home network. It can detect the network, but whenever I try to connect to it, it said "Windows could not connect to the (network).

    My other devices (iPad, mobile phone) can connect to him, so I doubt that it is a problem of modem?

    I have connected my laptop to the modem directly via an ethernet cable and it works. What is a network driver problem? Because I tried to update the driver, but they said that they are updated to the latest already.

    Someone help me please.

    Hello

    Thanks for posting your query in Microsoft Community.

    I understand that you are unable to connect to the network via modem, but thread and I'll be happy to answer your query. Let me ask you;

    2. When was the last time you were able to connect to the wireless network?
    3. Remember to no particular change in the computer before the show?
    4. What is the brand and model of the computer?

    Since you are able to connect to the network using the modem, it could be because of the card network is outdated or corrupted. I would recommend that you try the methods below and check.

    Method 1: Run the network troubleshooter

    Refer to the article below to run the network troubleshooter
