a macbook air connects to another network wifi not

Hi all

I visit a friend, and we have two laptops, iPhone and iPad with us. The iPhone and iPad connected without problem. Ditto for the new 13 macbook air inches. The second oldest macbook air is somehow stuck. I guess the network files are corrupt. Who should I remove? I restart the router and macbook air. I tried a clean profile, and yet, I get an error message... Sometimes it says password invalid or unknown error just. I know that the password is correct, and since I doubt my sanity have had several people enter or check it out.

Thanks for the help,

Philly

PS: Both are running any new version of El Capitan

A user using different admin for any reason seemed to have done the trick...

No idea why,.

  • Computer connects to the network, but not to the Internet, connect to the only local

    Hello world

    OK, so I have a HP computer with the installed version of Windows Vista Home Premium 32-bit. I've had it for almost 2 years now and have had no problems connecting to Internet... until now.

    I can connect to networks... both wireless and cable, but I can not get Internet. I used the IP, subnet mask, gateway and server settings DNS to another computer that works with this specific local network just to see what happens... my computer has failed.
    Until recently, I could connect to this WiFi connection in a coffee shop, but the last time I tried it didn't work. I've connected to the network but not the Internet. He told me that the DNS server did not. I'm starting to think that something is wrong with my computer.

    I saw that the solution for some people running the Norton removal tool, however I had uninstalled Norton almost as soon as I got my computer 2 years ago and ran McAfee instead. I don't think that Norton should have an impact on me more.

    Is there a solution to this problem... or I'll just have to try everything that is out there?

    Thanks for your help!

    Hi MomPlaysBass,

    Finally, my problem has been resolved - it wasn't my computer after all. The modem may only be connected to a computer. If you want to connect to another computer, you can connect the computer to the modem and then put it back. My computer worked fine after that. Whenever we want to switch between computers, even if I have to reset the modem.

    I don't think you have the same problem, but just in case, you can try to reset your modem - it's a button on the back or a small hole that you can reach with a pen... Hold the stylus for about 5 sec or maybe a bit more and then let go. That should reset your modem and might help you with your problem. Your computer should also have created a restore point... If all else fails maybe you can try to get back to the final point where your computer worked.

  • WRTG54S to connect to the network, but not internet

    I have a WRTG54S and Mediacom 12mbps. My router worked fine on my old laptop (a Dell Vista), he was sitting in a box for about 6 months and now that I have a new (Sony running 7) I can connect to my network, but not internet. I have updated the firmware of 7.6 to 7.8 without change. I have tried no security, wep and wap without change. Also, I cloned the MAC, once again no change. Windows cannot detect all problems, and when I try to activate the router to connect to the internet it always says connection failed. I can connect directly connected to the modem but not when connected to the router or wireless. Any ideas? Thank you

    Problem solved. I had to go to a Motorola SurfBoard 4100 to a 5100. Thanks anyway

  • MacBook Pro connects to the network, but other computers will be

    As of today, my Macbook Pro (approx. 5-6 years running Yosemite) has had problems to connect to my network, even if the other computers connect very well.

    On the menu bar, it shows that I am connected with a signal strong.

    My only guess is that the hardware is obsolete?

    Thanks to anyone who can offer help.

    What happens if you disable wifi then on again? Have you tried to delete the WiFi network preferences and put it back? What kind of messages if none pull you.

    Check the name of the driver that is installed by the printer. Make sure that it shows just the name of the printer.
    Click on the Apple menu, click System Preferences. Click on Printers & Scanners, highlight the name of the printer on the left side and right side of the screen it should show the name of the printer. (LaserJet MFP M125a Pro)

    If the full name of the printer is not correctly, delete and add the printer name back from the list. Click on the sign - to remove the driver and then click on the + sign to add the driver might have to drop-down list to select the name of the printer to add a click.

    How is the name of the printer listed?

    If the problem persists, try the following steps:

    Fix permissions of the drive on the Mac:

    Close all applications.

    In the Apple menu, click OK, click Applications, and then click utilities.

    Double-click disk utility.

    Highlight your hard drive / partition on the left.

    Click on check and then repair disk permissions.

    Restart the computer...

    Reset the printing system:

    Note: This will remove all printers in the print and Fax/Scan, any printer deleted can be re-added later by clicking the sign plus (+) symbol.

    Click on the Apple icon and then click on System Preferences.

    Click on Printers & Scanners.

    Make a right click (or Ctrl + click) in the left white side panel, and then click Reset printing system.

    Click OK to confirm the reset.

    Type the name and the correct password.

    Click OK to reset the printing system.

    Then click on the sign to add the driver, highlight the printer +. (you may need to click the drop down menu to select the name of the printer) Then click the Add button.

    Try to print again.

    If you need help, let me know.

  • Unable to connect to another network

    Greetings,

    I had already installed my deskjet 3520 and used wireless with no problems. Since then, I had changed my ISP and I bought a new modem and router with new SSID and password. Currently, I am facing problems connecting to my network again. Have tried all suggested ways for hours without result. Already reinstalled the software using the CD provided and tried to use the usb to connect from the path of the WPS does not work. He urged that it is impossible to connect the printer to the network coz of 3 reasons:

    (1) firewall - since disabled norton

    (2) router MAC activated - already disabled

    (3) different network

    Please help and see if you could get my printer to work again wireless. Thanks in advance for your efforts!

    After having tried to establish a connection between the printer and network for hours, I was finally able to operate using the WPS configuration. I tried to connect by holding button for 3 seconds the router WPS, but it still doesn't work. I does not come across any suggestion of HP I might need to ACTIVATE the WPS on my router configuration web page. Now I can connect wirelessly. Hope this help anyone else with similar problems like me and I thank you for your help also, sabretooth.

  • HP Pavilion 2 x 10-N000NA: HP Pavilion x 2 10-N000NA connects to the network, but not to the internet

    Hello

    I have a problem with my HP Pavilion 2 x 10-N000NA Windows 10, 32-bit version...

    I have a router TP-Link W9980 and the laptop connects to the 2.4 GHz network, but there is no internet access.

    However, if I use a range extender (powerline TP-Link Wireless extender), it connects to the network and the internet!

    So, I guess that the equipment is working well, there must be a setting somewhere?

    I've updated all the drivers, etc. for the laptop and the router.

    Any ideas?  Thank you.

    Hello

    Well, the strangest thing happened!

    There was a huge update of Windows, and it seems to have solved the problem.

    Connections now say '(network) secure' or '(network) open' - which they did not before.

    So now that I know that the network was very good and it was a laptop problem which needed fixing.

    However, I do not know what exactly the update fixed, so I can not pass on any knowledge to solve the problem of someone else who suffer.

  • G560 wireless connects to other networks, but not my home network

    Hello

    Got the 560 yesterday and set up was smooth. First thing I did was try to connect to my home wireless network, but it wouldn't connect. I checked the network password several times but it doesn't connect at all.

    All my other devices at home can always connect to my network. And the 560 connects to the network of my neighbour without problem.

    So I think that this is not a problem with the radio doesn't work.

    Tried to restart the connectivity and the computer several times, but has not made a difference. Does not resemble ReadyComm is installed on my machine.

    Someone had this problem? Is there anything I can try?

    FYI my home router is Netgear and is set up with WPA - PSK.

    Thank you.

    Update:

    Discovered the Atheros drivers were from 2009. Looked around the internet and found a newer version (although not later).

    Updated the drivers manually and its working fine now.

    PS: The pilot of the lenovo Web site download section is horrible... awful.

  • Can connect to the network, but not the internet, a "Local" access only

    Just installed a new router and am now unable to connect to internet on my HP laptop. The laptop is running Windows Vista 64-bit Service pack 1. Pulling him diagnose & repair window returns a message indicating "your modem or router is not available.

    I tried several things to get the internet to connect. I have reinstalled the driver, turned off the firewall, disabled the Internet Version 6 (TCP/IPv6) Protocol and manually configure the network connection.

    I have a desktop computer with a wireless adapater that performs the exact same OS as the laptop and I have no problem with this connection.

    I am able to connect to the internet if I connect the laptop to the ethernet cable. I am completely confused and would appreciate any advice!

    Hi Ima be,

    You can follow the steps below and check if that helps you solve the problem.

    Method 1

    Try to power cycle the router and the computer and check if it helps.

    On the PC:

    1. Save your work and restart the machine.

    On the router or modem (if wireless printing):

    1. Unplug the router and the modem.
    2. Wait 30 seconds.
    3. Plug in the modem and wait for it to come to the ready state.
    4. Plug in the router.

    After you put cycle check the connection between the router and the computer.

    Method 2

    If the steps above do not help, you mayreset TCP/IP stack. To reset access the link below and either click on "Fix it for me" or follow the instructions to fix it yourself:http://support.microsoft.com/kb/299357
     
    Disable the IP helpdesk:
    1 hold the Windows key and type R, type "services.msc" (without the quotes) and press enter
    2. scroll down to the IP assistance service, right-click on it and select Properties
    3. in the drop-down list box that says "Automatic" or "Manual", set it to disabled and then click 'apply '.
    4. then click on "Stop" to stop the service from running in the current session

To remove the IPv6, go to the properties for each network adapter, and deselect the check box next to the Protocol "Internet Protocol version 6 (TCP/IPv6), which will turn off, or select it and click on uninstall, which withdraw power off the computer.» Then go into Device Manager and remove any 4to6 adapters, adapters miniport WUN or tunnel adapters.
    NOTE: You should do this for each network connection, even if they are disabled.

    Method 4

    Disable the DHCP Broadcast Flag:
    Link: http://support.microsoft.com/default.aspx/kb/928233
    Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:
    http://support.microsoft.com/kb/322756.  How to back up and restore the registry in Windows
     
    Windows Vista cannot obtain an IP address from certain routers or some non-Microsoft DHCP servers
     
    To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:
    1. Click Start, type regedit in the search box, and then click regedit in the list programs.
    2. If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
    3. Locate and then click the following registry subkey:
    4 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ {GUID}
    5. in this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
    6. on the Edit menu, point to new, and then click DWORD (32-bit) value.
    7. in the new area #1, type DhcpConnEnableBcastFlagToggle and press ENTER.
    8. right click on DhcpConnEnableBcastFlagToggle, then click on modify.
    9. in the value data box, type 1 and then click OK.
    10. close the registry editor.
     
    By setting this registry key to 1, Windows Vista's trying to get an IP address using the BROADCAST flag in DHCP Discover packets. If that fails, he will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.
    You can also try uninstalling and reinstalling the driver for the wireless card.

    I hope this helps. Let us know the results.

    Thank you and best regards,

  • E-all-in-one printer, HP Photosmart 5520 connected to the network but not detected by computers

    Hello!

    My printer HP 5520 indicates that it is connected to my network, but the wireless printing does not work correctly.

    In the implementation of the process of the driver software the printer displayed after resetting my router, a Huawei HG655d. I get a "no connection" error when I try to send a print job to the printer. Function AirPrint doen and the printer is not visible on the iDevices. I have the latest version of my OS (OS X 10.8.3) installed, I also tried to reset and reinstall my router and my printer several times but nothing works.

    Is there a way to make printing wireless correctly?

    Access my printer directly via its IP address works, so the network connection should work. I've added details of the network below:

    Your router may not support Hello, who need your Mac to find the printer.  Enter the configuration of the router and see if there is a way to activate it.  It is sometimes called mDNS.

    Additionally, make sure that the multicast is enabled.
