Why can't connect me to wifi without ethernet cable

I can't connect to my wifi, unless my ethernet is pluged in... I'm using VGN-NS135E n OS is Windows 7


It's a little hard to follow, but I'm guessing that you mean that you get only Internet when wired with an Ethernet cable from your router to your laptop and wireless WiFi doesn't at all?  Or do you mean that you get a wireless connection only when an Ethernet cable not connected what whatsoever, is plugged into the Ethernet port on your laptop?

  • Why can't connect me to Internet Via Ethernet?


    I help set up the iMac to a friend. No problem problem connecting to Internet through WiFi but can not get the connection via Ethernet. Cables checked and ethernet and all are in working condition. Took some screen shots but I'm not good at all with this stuff. Can someone explain where I'm wrong. Of course, it's simple for a person - but not for me!

    That's what I mean when I open the network tab:

    I'm not with the Mac today so instructions to take with me would be very appreciated.

    Kind regards.

    Are plug you the ethernet cable directly to one of the ports on the router to the ethernet port of the iMac, rather than through network extensions? If so, and it is not working, you have another ethernet cable, you can try?

    If the cable connections are good and it still does not, you can try a reset SMC and NVRAM (PRAM) and then test again:

  • Why can't connect using Apple Airport WIFI of my remote security cameras but can connect using the Xfinity WIFI Modem/Router open?

    Why can't connect using Apple Airport WIFI of my remote security cameras but can connect using the Xfinity WIFI Modem/Router open?

    Two possibilities:

    (1) your airport WiFi might have a network name that is not in line with best practices, wireless

    A good wireless network name is...

    ... In short no more than 20 characters

    Simple... no special characters like an apostrophe, dollar sign, asterisk, etc.

    Compact, without spaces in the name

    For example, a wireless network network name as... red .dfedoryk Apple wireless network... .is not what you want. Something like... .dfedorykwireless. .. masse are much more likely to connect to non-Apple devices.

    Same guidelines your password

    (2) Apple gives the same name to network 2.4 GHz and 5 GHz network that produces double router band.  Some non-Apple devices are confused by the present, you may need to use the option to assign a different name for the network of 5 GHz on the router from Apple. Then, 'point' your device to the network name specific to which you want to connect.

  • Can not connect to the WiFi on MacMini 2014

    When I try to connect to any WiFi on my MacMini it says ' Unable to join, try to get closer the router. but the router is right next to my Macmini.

    In addition, my wifi connection is correct. It is easily connected to my iPad and iPhone.

    I tried transferring a file using release from my iPad to MacMini. It worked.

    When I tried to connect to the MacMini with ethernet cable, it worked too!

    The only problem is that I can't connect to the router using the wifi on my MacMini.

    What should I do?

    Try to create a new network location:

  • A motor with encoder closed loop. Can I connect an other encoder without using an engine and double regulation?

    A motor with encoder closed loop.  Can I connect an other encoder without using an engine?

    Thanks to LabVIEW with a PCI-7332 and an UMI7774 interface to control a stepper motor with encoder feedback.  System is configured in closed loop for the control mode.  You will need to add a different encoder to the system without attaching a motor.  I'm validation of encoders to each other.  Is this possible?  Should what kind of latency I expect?  I have attached a simple vi.  Need to buy one before the answer.

    Thank you

    You can just plug the second encoder to the second slot without an engine it. Then you can use reading encoder Position.flx to read its position or do whatever you want with it. What about latency times, how are you trying to go under?

    I can't connect to my WiFi using windows xp SP3 on bootcamp for Mac OSX Snow Leopard 10.6.8

    On the side of my computer's mac, the internet works fine.

    I do this to play Halo on my Mac.

    This is the problem (which I corrected).  It's simple, all you have to do is to switch to XP, insert your mac installation disc and follow installation bootcamp, with all the drivers for mac compatibility.  The wireless just popped up as active.

    I lost my, but this isn't a problem: just go to the apple Web site, use the express track, diagnose your problem and have a representative call you.  They answer in a few seconds.  Replacement CD is very cheap ($16-2011).  You can get the CD of requests for replacement, which is another $ 16, but it is not important; XP does not use it, only the operating system for the drivers.  Mine came very quickly, in just 2 days.

    Hope that answers questions from the Internet.

  • Why can I connect course websites (https), but sites (http) not ordinary?

    Why can I connect on websites (https) course, but when I try to connect a site (http) regular I get the message that the internet explore cannot display the Web page.

    I guess I have a bad setting somewhere, but can't understand what to change.

    Http and https use different ports.  Look at your firewall programs to determine if port 80 is blocked.  Temporarily disable the firewall programs, to see if this is the cause.

    Sometimes the following freeware program can resolve IP stack corruption as well.  Try to run WinSockXPFix if nothing else works:

    I can't connet Internet whith this net card, but I always connect it with a wireless network card


    I put t know why you can not connect to the internet, but we need to study a little.
    Have you checked if the network card has been properly installed? The network adapter appears in Device Manager correctly?

    What do you use to connect to the internet; Modem or router WLAN?
    Have you checked the TCP/IP protocol if the IP address setting has been configured to automatically get?

    Check if there is an active firewall

  • Why can't connect me to my network to work, but I can connect to my home netwrok

    A few weeks ago, I went into labor, connected to the network.  After doing other work, I went back to my computer typed a document and press only to notice that I was no longer on the network.  There was no interruption in power, the computer does not cut: he was sitting on my desk.  At this time there, the network wouldn't let me turn it on again.  I would get a message saying: he can't connect because it timed out or due to the action of the user.  I rent a space in a small office - there is no information TECHNOLOGY staff.  The landlord had someone and have reconnected.  I could connect the next time I was in the office with no problems.  A week after I got back on the same thing happened, and even once I can't always on.  There is someone else coming into the office during this period (I'm with a patient when she arrives so it is in the same time of 30 minutes each week, the same day) and I wonder if when she connects could it be me?  The other day I work, I'm the only one in the office, and when this was corrected at the first time that I could get that day without incident. No one else has this problem-, but they're working on the time where that other person is not in or it's already here and connected when they arrive.  What can I do for this fis.  From now on, they tell me this is my problem and that it must be my computer but I can't connect to my home network without problem.  I am getting very frustrated because I need to go to print documents or really work on something outside to see my patients.  What could be the problem?  I think the last time that he has been fixed, they reset the router, but they won't touch me any equipment.


    I imagine the inconvenience that you are experiencing. I'll certainly try and help you in the matter of fixing.

    To help you to propose measures to solve the problem, I would appreciate if you could answer the following questions:

    1. how many users is configured on the computer?

    2 are logged as administrator?

    3 have you logged on a domain?

    4 is it a cable or a wireless connection?

    5. you have any antivirus installed on the computer program?

    6. are you aware of any recent software or hardware on the computer changes?

    You can disable temporary, your security software and check.

    How can I turn on or turn off the firewall in Windows XP Service Pack 2 or later versions?

    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 do not 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 during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    You can also try the steps and check if it helps. (You must be logged on as administrator to run the steps)

    a. Click Start.

    b. click on run

    c. type cmd.exe, and then press ENTER.

    d. type the following commands, and press ENTER.




    ipconfig / renew
