"Cannot connect" and I'm stumped.

I could not connect to the Internet (through AT & T) all day (early 2011 MacBook Pro, OS 10.11.3 and a wired Ethernet modem).

As soon as I start it, I get the following error message:

"Network connection: the connection failed because the communication device is not available." Make sure that it is connected to your computer, and try to reconnect. "(I did, but it does not help).

In system preferences: network: "AT & T DSL: not connected" and "Ethernet: not connected." The Ethernet cable is not plugged in or the device at the other end does not respond. »

I have no Internet connection problem with a utility boot disk, which has network settings and account Internet identical to those on the drive hard internal and is essentially a put to update the clone of the drive of the MacBook.

When I checked the MacBook with disk utility, as a first step, he reported some problems with partitioning [!], but when I ran disk utility, again, he has reported that "the partition plan seems to be OK." Disk Warrior noted no problem. The button "Help me" in the network reports 'Not connected' preferences as above, but does not offer to fix it.

I've never had this problem before, and I see no option except to wipe the hard drive and reinstall from a Time Machine backup (a little intimidating because I've not done this before either).

Grateful for the advice.

Can be restoring from time machine is a good idea. It's easy, you start your Mac in the recovery mode by pressing Cmd - R and the power button. Then begin to restore. The only problem is that it is a lot of time.

  • Ad Hoc network. even if the network is active and is connected to the internet my devices cannot connect and then the network shuts down.

    I'm living in a college dorm and only have access to the internet via a hard line to my computer. So I wanted to give my other accessibility of consumer electronics set up an Ad-Hoc network and share the internet connection. When I originally set up the network it works fine, but after the devices go to sleep or I leave the room it stops working. I had problems to keep the internet connection to share continually, which I fixed it. I then had a DHCP problem with the hard line that has been resolved through troubleshooting function. Now, even if the network is active and is connected to the internet my devices cannot connect and then the network shuts down.

    Is there a way to create an Ad Hoc network that works similar to a wireless router, so when my computer is turned, it works automatically? If so, how can I make this happen without these problems?

    Hello

    I suggest to activate temporarily the antivirus as well as windows firewall and check if it helps.

    Important note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

  • Cannot connect and use 2 hard drives Canvio de Store.E at the same time

    Hello

    I have 2 devices Store.e Canvio: 2 TB and 3 TB respectively but it seems that I can't connect/use them at the same time, as if I do it, one of them (the last I connected), becomes inaccessible ("access denied").

    If I disconnect the first device I connected, the other starts to work,

    Is an odd question, and I can not find someone to live something similar...

    No idea how could it be the cause, or how can I solve it?

    Thank you

    I m wondering if the same problem is displayed using another computer or another USB hub with an additional power supply.

    From my point of view of the few this problem could be related to the low power provided by a single USB port.

    The two hard drives seem to support the USB 3.0 standard.
    The USB 2.0 port common provides 500mA and USB 3.0 requires 900mA
    This means that two USB devices connected simultaneously use 1800mA which could be too much for the USB ports for s laptop

  • Cannot connect and more as a user apps

    I created a EUL APPS using the instructions provided by link: Armstrong-Smith Consulting and am able to connect administrator discoverer as SYSADMIN and administer the EULS that was created under a DB account.

    I gave the administrative rights to a business district to an apps user.

    I try to connect to Discoverer Plus and/or Viewer by using the user account apps with administrative rights for the company in the EUL above and get the following error;
    < p >
    Error < strong > < facilities >
    A connection error has occurred.
    -Unable to connect, perhaps due to an invalid parameter Applications GWYUID. Please contact your discoverer Manager.

    How can I go about connecting to the EUL APPS or I am that approaching the wrong way? The final objective is to implement the end users who can use this license to create reports for our installation.

    Hello
    It's Kevin? :-)

    If so, I sent you a response to an email. If this isn't Kevin, here's a possible solution:

    Looks like your APPLSYSPUB account has a different password for the standard PUB. For this reason, you need to change this setting in your pref.txt file.

    If you look in this folder: * $ORACLE_HOME\Discoverer\Util * you will see a file called pref.txt. Edit this file and look for the GWYUID setting and change the password to match what you have inside the admin.

    After editing the file, save it, and then starting in the same folder, run the file called applypreferences. Under Windows, it's a BAT , under Linux and Unix file, it is a SH file.

    After you apply the privileges you must stop and restart the server of discoverer using opmnctl stop followed of opmnctl startall when executed since the * $ORACLE_HOME\opmn\bin file *.

    That should do it.

  • Excellent signal, but cannot connect to the wireless network

    XP Pro Client has been connected to the area by cable network, but now we need to connect in wireless. Card of TrendNet USB Wireless-N, no problems. The light is on the card, and the network is visible with a signal strong. When I try to connect, I get the message that it cannot connect, and the network may be out of reach. Sometimes, I get a balloon indicating that one or several wireless networks have been detected, but when I then try to connect, I get the same message. The PC is about 10 feet below the access point, with only a counter between the two. I have uninstalled, reinstalled, tried to update the driver, etc. Any help would be appreciated.

    Thanks for your help - problem was solved using the TrendNet utility to connect and add the key instead of using the Windows utility.

    Get the message "This Mac cannot connect to iCloud due to a problem with my Id, open Preferences to solve iCloud iCloud" after entering my password which is accepted and then after a minute or two messages is.

    I'm your pain ptapp!

    Through my research for an answer that solves this problem, I have found that not even Apple knows how to solve this problem of password to iCloud.

    All 4 of my devices constantly ask my password because of some problems with xyz account.

    Then I enter the password only to be told that iCloud cannot check my password.

    Then after several repetitions of this I get locked and have to go to the site apple id to change my password.

    I didn't spend $6 000 on these beautiful devices so I could spend countless hours dealing with support (with no positive result) and find themselves just beyond myself in frustration. I have a Mac Pro, 2 iPads, 2 iPhones and an iPod touch. All are behaving this way, no matter what it is I'm doing at the time.

    Apple needs to fix this problem, if they have any idea how to.

He also grabs focus, no matter what I do - I watch full-screen movies, writing in a web form, play games, out of a keynote with a client presentation. Very, very frustrating. Not the kind of behavior I've seen in Windows 2000

    If I click on iCloud preferences I receive a request to enter my Apple ID password in the Panel of the iCloud system. I have enter my password and get an error not found Keychain with the message box:

    Impossible to find a keychain to store "281711789."

    If I click Cancel the previous password box returns "an unknown error has occurred." The problem goes away, but I have the original pop up within minutes.

  • A Wi - Fi connection does not have an IP address and cannot connect to Internet

    Here's my question:

    "Wi - Fi doesn't have an IP address and cannot connect to Internet"

    But he connects.  I use the model of airport Time Capsule ME182LL/A and the last OS.

    The reason why I suspect the problem is that my Samsung smart TV will not connect to internet, but connects to the WiFi.

    Do I have a problem when the network preferences indicates my network with a point orange and says 'No IP Address'?  It doesn't have a green dot next to the Wi - Fi connection and it says connected.  I'm puzzled.

    Thanks for any idea that you can provide.

  • Administrator account has been disabled and cannot connect at ALL.

    I own a 'HP G71-340US Notebook running Windows 7"and I'm trying to restore my computer completely (for delete). Then at some point when I turned on the computer a few days ago, it took me in the Recovery Manager, I couldn't do anything. I try to restore the computer like new and said, it will reboot several times. I let him, then I see an error saying that it cannot restore. I click Ctrl, Alt, Del and was able to connect outside of that. Then after that he showed what to connect to. I click on administrator (because I'm the administrator of this computer) and it says disabled account, see your system administrator. Then I click on another user, he gave me the opportunity to put a username and password, but it keep saying that the username and password is incorrect. So I turned the computer off, waited 10 seconds, then he tries to put in place like new, it took about 20 seconds and then a different error comes up saying, 'Windows cannot install, please restart to install. I did so many times that I think I messed up my computer. I can't even contact HP to the computer in the Recovery Manager, and I can't go to Safe Mode.

    Due: I got more than 458 Trojans, rootkits 2 and 0 viruses on my computer (as it is said when I scan the computer until errors have shown).

    And please do not ask about Trojan horses, I don't know how that happened on my computer.

    NEW PROBLEM: I turn on my computer this morning, it says «Set up as new computer...» "then he takes me to the screen host then within 20 seconds, he said that" windows cannot install and the computer must restart. " "I let it restart about 3 times and still nothing. I try to get into Safe Mode, but it won't load at all.
