Internet connection suddenly does not work

My computer suddenly stopped being able to connect to the internet.

I use a Belkin Surf & share Wireless... Dongle USB and never had any problems before.
The router works fine, I connect to it on my roommates Mac here where I am writing this question.
If I can connect to the router and system tray icon says I'm connected. But when I open Chrome or Opera or try and connect to a FTP server (which I need to do for work!) I can't make the connection and the sys tray icon changes from normal to problem with yellow exclamation sign. When I run a diagnosis it is no problem, and when I look at the details, he said "it can be a problem. The funny thing is that sometimes this translates the sys tray connection status icon back to normal and very occasionally, I am able to load a web page, but then the connection breaks again.
Here is the ipconfig/all command Info:
Windows IP configuration

Then, there's stuff on tunnel adapters
I really need to make it work for my work, ideas, what could be the problem?
Thank you

Hello

To provide the proper resolution, I would need more information on your side.

1. deal with any issue while using Internet Explorer?

2. is the specific issue while trying to open the FTP server?

3. deal with any issue while accessing other Web site?

This problem may occur corrupt or incompatible drivers, missing updates or because of incorrect network connection settings.

Method 1:
I suggest you try the procedure described in the article and see if it helps.

Method 2:

If the problem persists, I suggest you try to reset TCP/IP. Check if it helps.

  • Internet connection sharing does not work anymore

    I have used Windows Vista Home Premium for 2 years now on my laptop. Internet connection sharing enabled to connect to the internet via my wireless adapter and allowed me to share my internet connection through the ethernet port. He worked for more than a year. All of a sudden 4 months ago Windows Vista doesn't let me share the internet connection more. When I go to networking and sharing Center, click on "Manage network connections" and it shows that my "Wireless Network Connection" is always set to share. So after reading several forums, I clicked on wireless network connections and click right properties. Then I clicked on the sharing tab, to make sure that "Allow other network users to connect through this computer's Internet connection" has been verified and that it is. After that, Windows Vista will not always share the internet. Someone suggested that I double check the IP version 4 and 6 on the wireless and Ethernet connection were defined on IP addresses obtain automatically, and they are. The computer still will not share the internet connection! I even took the manufacturer in the view of portable and made sure my cable modem Simulator wasn't bad. I took it to a computer store and we checked the crossover cable. Everything is fine! What else can I try?

    Obtain an IP address automatically is the wrong setting on the Ethernet connection.  To return to the sharing tab and unshare the wireless connection.  Close all windows network, and then open them and re - share the wireless connection.  Who must configure IPv4 for the Ethernet connection properties for:

    IP address: 192.168.0.1
    Subnet mask: 255.255.255.0
    Default gateway: no
    DNS server: no

  • internet connection wifi does not work after entering safe mode

    It works when I connect it to the router with cable, I had this problem before & there was a command typed in cmd that solved but I can't remember it, any help?

    Interesting... If you have booted without failure then you restarted in normal mode and your wireless settings no longer work?

    UH... Well the first thing I would do is to disable and reactivate my wireless card.  The second thing I would do is check I get an IP address on my wireless network, this is done in the command line (cmd) by typing "ipconfig".  If you get an IP address then you know that your router works on the dhcp protocol, but to confirm I would ping the router, which will be your entry door, which is usually something like "ping 192.168.1.1".  If you do not have an IP address, you should try to renew and see if you can buy a... "ipconfig / renew".

    In addition, you will need to check that you are actually connected to a wireless network, it should appear in your software wireless windows, or you proprietary wireless NETWORK card software.

  • JavaScript in Internet Explorer still does not work

    I followed all the steps of http://community.skype.com/t5/Windows-desktop-client/Solution-for-empty-blank-login-screen/td-p/1008... but still javascript does not work on Internet Explorer 11 (Windows 7, 64-bit, with or without the module running). I even reinstalled Internet Explorer.
    I also added skype.com to trust sites and everything, that must be enabled to allow working active javascript.

    I did the LoginCleanup and it says "System cannot find the path given." and twice "system does not have the given file". (translated from the German by myself, I guess than its counterparts in English)

    Well I think that regsvr32 jscript.dll and regsvr32 jscript9.dll worked well in c:\windows\syswow64 and c:\windows\System32, files can be broken (perhaps other software changed). How can I fix this problem without having to download the files of the suspiscous websites?

    Thank you

    Scripts can be disabled by your anti-virus application.

    Now try IE11 uninstalling and reinstalling IE9.

    In order to uninstall IE11 you should go to the Windows Control Panel-> program and features-> view installed updates-> Microsoft Windows-> Internet Explorer 11.

  • iPhone 6s and carplay connected but does not work

    It has worked before and now does not. I deleted the system carplay phone and indicated above. The iPhone says bluetooth is connected to carplay and carplay indicates it is connected to the iPhone, but it does not work properly. I can't get or receive calls. I hear the phone ring on incoming calls by speakers in the system several times and when I touch the phone button my steering wheel to answer does not work, or it shows the phone number entering on the radio screen. When I try to make a call, the iPhone does not, I call say they have heard their phones ring but could not hear me speak, phones sounds dead on both ends. I have to disconnect carplay to make and receive calls.

    As side note my iPhone and carplay work with audio for listening to music, but who also has been removed from carplay so that I can put in place the phone carplay only system.

    Any suggestion would be appreciated.

    Concerning

    Steve

    Nevermind, I figured it. I completely turned off the iPhone and he turned his back, and then just followed the car game voice instructions to synchronize.
