Windows 7 - NO INTERNET CONNECTION - connectivity continues to lose!

WIndows 7 says that it allows internet connectivity easier and better.  So why it keep the loss of internet connectivity and need me to restart my router and the computer to get it back.

At worst, this happens a few times per hour, at least once per night.

As a result of some other positions, I created an IP (rather than letting the automatic form).  I disabled the server Hello DNS in the Services, but still the warning triangle appears and identifies my network but said 'no internet '.

The router has been replaced by my service provider and the problem still persists.

I can access the internet via my router with other devices when my PC at home with wired connection says no internet connection, which proves that the router is ok.

Troubleshooter also can't find anything wrong.

Nobody knows how to solve this problem, because Microsoft will help only if I pay a lot of money and DEll (who sold me the computer) do not care even if the computer is only 4 months old!

Help, please!

I forgot to mention that I have Windows 7 Professional

  • RV082 and Windows 7, no internet connection with active firewall

    Hello

    I have a 1.3.98 - tm firmware RV082 and have recently upgraded several Machines to glass & RC for testing, but they can't access the internet.

    They can access all the other mahcines internal, but cannot ping the router.  The first Pc I upgraded was beautiful and accessible to the internet without problem.

    The second started Ok but then loses the internet connection.  It can access all internal machines and if I reboot it with XP (dual boot) it works fine.  He has been an operational machine without problems netowrk for 2 or 3 years.  I tried a diffetrn nic card and another cable froma different wall point in case there was a problem that XP could cicumvent and Windows 7 has been more difficult.

    Now the second PC has started doing the same thing and wont connect to internet.

    If I disable the firewall on the RV082 Windows 7 PC connect correctly.  Can I wathc the tray icon of system on the State of PC modification simply chagnign the status of the firewall on the router.

    Occasioanlly a PC will continue to work for a short period before losing internet again or blocked him.  I have checkled newspapers and others are no entries in the standard newspaper.

    I bypassed Vista Batteux ther so a setting or something I need to change on the window smachines, but as I have Windows 7 on test in withotu the Council to clarify a problem and my two lapotps and have connected through various cafes, Internet etc. even in Spain and Brazil without problem I tend to think it's a problem with the RV082.

    Any ideas would be helpful?

    Hey Kevin,

    To clarify, we have not heard of this I didn't think (I am curious as well), did this start happening when you upgraded the computers?

    Its sounds like it from what I've read, and also you can generate by activating and deactivating the FW on request, but this didn't happen until you have changed the PC SW?

    If it does, then, looks like soemthing SW PC made and maybe you can endure a wireshark trace and try to sniff which continues when the PC tries to access the internet.   I'm not asking to review track, only that it can help you.    If you feel like it is a defect of the Cisco product, you can open a folder with the Small Business Support Center and they will watch the track with you.

  • Windows Update causes internet connection to stop working

    I installed the recommended Vista updates last night and this caused my internet connection, to stop working.  This has happened to both of my HP laptops.  I was able to work around this problem by going to a previous restore point but worry about future updates, causing the same problem.  Please notify.

    Hello

    Use a wired connection to download the latest drivers or download on another computer
    and transfer them to this one on removable media such as CD, DVD or USB drives.

    Control Panel - device - networks - WiFi - Manager write down of the brand and model, and then double-click
    on the drivers Tab - get the version number. Then double click on update drivers (this can do nothing
    that MS is far behind the drivers of certification). Then make a right click on the device and UNINSTALL - REBOOT - it
    will update the driver stack.

    Now, go to the system manufacturer and search for updated drivers, this will be your fallback. Then go to the Site of the manufacturer of the device
    and look for the even more recent drivers.

    Download - SAVE - go to where you put the driver - CLICK RIGHT to it - RUN AS ADMIN
    (repeat on the site of the manufacturer of the device)

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  • questions of google chrome windows 7 PC internet connection tech support

    So basically for now, I need some serious tech support. I knew enough to power a computer for regular use, but now I need to know a little more.

    I'm working on a pretty nice software that probably has not been treated well for about a month so its starting to develop some small bugs. I intend to use this laptop for more things in general so it needs work better.
    I ran some scans norton (but my norton is literally about to expire so I need something safe for my computer out of Cnet maybe? it's free)
    I ran a quick defrag and I have Ccleaner and know what it does, so I ran too. I have not just be completely shut down the computer, I don't even have a back upward in car big enough for my computer or anywhere to put it if I had a. Im doing the laptop on the lap a lot which means no doubt that fans do not get enough air.
    There is a laptop stand that had fans, but fans broke and its just bulky right now so I'm just trying to protect the screen and not get any fluid on the keyboard. Also, there is just no office about so its that or directly on a mattress that is worse.
    (Also I keep multitasking for many, even for an upscaled laptop with windows 7 and the changes to make it work well.) His breaking our internet connection wifi is not totally reliable here and all I can do, is disconnect the boxes and wait but its such a nuisance that I can't do it too)
    Any help you can offer would be great!

    Hello

    I suggest you to start the computer in a clean boot state. Clean boot helps eliminate any conflict of third party software.

    Note: when you are finished troubleshooting, follow step 3, mentioned in the article to start the computer to a normal startup.

    If you use WIFI put a check mark next to it and let the service when you disable startup items.

    For the safety of your computer, you can download and install Microsoft Security essential, which is a free anti-virus program.

    Here is an article on wireless connection problems and wireless network. Take a look and check.

    Hope this information is helpful and let us know if you need help in the future about Windows. We will be happy to help you.

  • After an update of Windows (XP), my internet connection hangs up

    Earlier this summer after letting one of my netbook computers have a "update" for Windows my connection switched to internet hangs up.  I don't have to troubleshoot it at the time because I got another XP netbook that had not been updated and it continued to work.  Unfortunately the next time I had a connection high speed available let him update this netbook also, and now it crashes on the dial-up connection.  In both cases, I use the same modem.  I connected the modem to a Windows 7 computer and he composed and connects to the internet and works very well.  It's something to do with the Windows updates for XP netbooks.  Is there a known issue with this?

    ... I am a little concerned about any specific questions about my internet security

    You should be concerned!  McAfee (and Norton) applications are notorious for not not upgrade (or uninstalling) itself.

    Note: The following assumes that none of your McAfee subscriptions (or free trial period) have already expired...

    [You may want to print these instructions for reference offline. [If a step said to restart, restart! ]

    1. download the McAfee Consumer Product Removal, save it to your desktop tool: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

    2. close all open applications (that is, anything with an icon on the taskbar).

    3. physically disconnect the computer from the internet and local networks.

    4 uninstall McAfee Internet Security via Add/Remove Programs & reboot.

    5 IMPORTANT! => Make absolutely certain that the Windows Firewall is enabled (Yes, even if you are not connected to the internet).

    6. double-click on the file that you saved in #1 above to run the utility. DO TAP not your keyboard until the race ends, then reboot again.

    7 to reconnect your computer to the internet. Do NOTHING else online until you have completed ALL the steps below!

    8. do a clean install of Norton Internet Security using your CD.  If you purchased the software directly from McAfee, go to https://home.mcafee.com/Secure/Protected/Login.aspx to connect and download your software.  FOLLOW ALL THE INSTRUCTIONS!

    9 IMPORTANT! => Manually and repeatedly updating McAfee Internet Security until you get a "not more than updated" or similar prompt.

    10. open Internet Explorer (only!) to http://support.microsoft.com/kb/923737 & run the difficulty.

    11 IMPORTANT - DON'T SKIP THIS STEP! Open Internet Explorer (only!) to http://support.microsoft.com/kb/971058 of => [ignore all DO NOT APPLY or NOT RECOMMENDED warnings] & run the difficulty in DEFAULT modes and AGGRESSIVE. [1] [2].

    12 restart a last time & test.

    ===================================================
    [1] reject (close) "automated convenience store" solve this pop-up that appears when you open the Web page, and then run the difficulty he 50202 (in DEFAULT and modes and AGGRESSIVE) instead. If needed, you can click the difficulty he 50202 & SAVE the download to your desktop and then run it manually (in DEFAULT and modes and AGGRESSIVE).

    [2] full Disclosure: the difficulty operating in AGGRESSIVE mode will remove your update history but not the list of installed updates.

  • Windows 7 - no internet connection

    I have two laptops - I had to rebuild a (the girl had viruses of games). After the reconstruction, the computer connects to the router, but not to the internet. It is not a router problem as my other laptop is always connected to the internet, very well. I restarted the router anyway, restarted the laptop, but still nothing.
    I'm guessing he puts some, but I can't locate the problem. I browsed through the forum and found similar, but not with a reconstruction questions or anything like that. Can anyone help?

    turns out it was something as simple (as in so simple that I have does not seek first)-c' is a Norton Internet antivirus which was obsolete. The trial period wore off and after my reconstruction, he always tried to reconnect and because it has expired, it wouldn't let me on the internet at all. I uninstalled it and everything works now.

    Thank you all very much to offer help and advice!

    New notice: get rid of all the products of Norton or McAfee.  There are some freeware products antivirus out there that do the same (or better) work, use fewer resources and cause fewer problems.
