WiFi is connected to the router, but "no internet access?

Hi I have a Samsung r519 laptop with windows 7. I am connected to my routerbut I can not always connect to the internet. I think that the problem can be on an ip address, dns or parameter setting of the server. My ipv4 settins are set to 'use ip address of followig' and 'use the followig dns servers. My ipv6 settings are set to automatic. I would like to know if you want pictures of my computer screen. Help, please.

Hello

Thanks for posting your question on the Microsoft community.

I would like to know some information about the problem so that we can help you better.

Did you do any hardware or software changes to your computer recently?

I would suggest trying the following methods and check if it helps.

Method 1:
Run the network troubleshooter
Reference:
Using the troubleshooter from network in Windows 7
http://Windows.Microsoft.com/en-us/Windows7/using-the-network-troubleshooter-in-Windows-7

If this does not help, then use method 2.

Method 2:
For the DNS server, follow these steps.

a. Click Start. Type cmd in the search box and press ENTER.

b. in the command prompt window, type the following command and press ENTER:

ipconfig/flushdns

Note: There is a space between ipconfig and /.

It will show you the message successfully empty the cache of DNS resolution.

c. again once, in the command prompt window, type the following command and press ENTER.

ipconfig/registerdns

d. type the following command at the command prompt and press ENTER.

ipconfig/all

The command ipconfig/all command displays for all your network adapters, TCP/IP in Windows settings.

If your IP address of your Local network connection is 0.0.0.0 or 169.x.x.x (where x is a number any), then your computer does not receive an IP address from router.

If this is the case, try this:

a. type ipconfig enough at the command prompt and press ENTER.

b. then, type ipconfig / renew in command prompt and press ENTER.

The test again by typing ipconfig/all to see what is the address?  (If you are on a router, it should start by or 192.168.0.x or 192.168.1.x 10.x.x.x)

Then, if the problem persists, use method 3.

Method 3:
Please use the suggestions contained in this Microsoft support article and check the issue.

I hope this information helps.

Please let us know if you need more help.

Thank you

  • WIFI connects to the router but no internet connection on 15R 3521

    Hi, the new laptop 3521 with Win7 Pro the WLAN will connect to the selected wireless router but is unable to establish an internet connection.

    WLan Driver 1703 was duly installed once the Chipset driver was installed, as recommended.

    Fortunately, other mobile devices to connect to the same router. Ubuntu on this laptop was also happy to connect to internet on WIFI, only Win7 fails.

    Disabled the Win7 firewall, but no change. This connection, unidentified in the network and sharing Center.   Router SSID etc have been entered correctly. Remove the WLAN profile and not reinstated, no change.

    Tried to connect to another router wireless with the same result. I can only run this laptop on wired connection to the router.

    I am at a loss as to what other steps I could take to correct this key WLan / internet access.

    Any suggestions would be welcome. See you soon.

    Hi love,

    Thanks for your advice. I deleted the profiles (two identical found!), also removed all entries of all WiFi routers in Win 7 registry. This step has not resolved the problem.

    However, I found the reason for the connection problem and the solution is the following:

    In the wireless connected (TP-Link) router, wireless--> channel settings is set to 'AUTO' (which is to select automatically 20 MHz or 40 MHz).

    In the device driver Dell WLAN 1703 (properties--> advanced--> bandwidth 802.11 n, the value has been set on (ie the Atheros is the default!))  "20 MHz.

    Once I put the option value "20 MHz / 40 MHz Auto", the connection comes to life.

    What a relief!

    The question is now completely resolved. Thank you to all who have contributed.

  • Samsung S6 connects to the router but no internet

    When I switched to xfinity I bought a C6300. I had problems with the first not allowing my NAS to connect so I exchanged against another. My phone would connect to the router and work fine for awhile then lose Internet connectivity. The only way to get it back is to reboot the router. I tried several different units, and I am now on a C3700. The problem still exists and seems to be deteriorating. All of the suggestions.

    I solved my problem by replacing the Netgear with a Zoom. It was the only one that I could find who said it would work with Android. I hope that Netgear will get things straightened.

  • Connected to the network but no internet access?

    I had problem connecting to internet. What is happening is that my computer connects to my wifi network, but then a yellow sign with exclamation sign will appear and it says "no Internet access. I'm tired of checking my browsers and they do not connect. I tried ping and he said something in the sense of "cannot find server". Tried to update the drivers, but either they are up to date, or even can not be updated because it is not connected to the internet. Finally, I tried the system restore, and it worked miraculously! But now, about a few days later, the problem came again and I restored the system again. But I thought I can't do this forever. Is there a way to fix it or at least to know what is the problem?

Both computers on the router has the same problem.  I did a reset the router back to the settings by default and still no luck.  Any thoughts?  Thanks in advance for the help.

    The first thing you can try is when you the Modem and the router is connected to the other, disconnect the power from the router and Modem, wait 30 seconds and then plug in the power to the Modem and once all the lights are solid, then connect the power supply to the Linksys router, now check if you are able to go online. If still no then...

    Method 4:

    You can temporarily disable the antivirus and firewall on the computer and see if it helps:
    Enable or disable Windows Firewall
    NOTE: Turn off Windows Firewall might make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.
    You can see the following link to disable the Antivirus installed on your computer software.
     
    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

    Please follow these recommended steps and post if you still experience the problem. I'd be happy to help you further.

    If I turn on my laptop, I am required to get out of the kitchen and stand near the router until it connected, but if I'm sitting in my room, 3 bars, and said "(the WiFi name) cannot be detected/connected."

    Simply said, the Wlan router signal is too weak and this causes disconnection
    I have some advice for you;

    -Update the WLan driver
    -Card Wlan definition of control; You should go to Device Manager-> properties-> Advanced tab WLan card. You will find some options that allows you to change the standard WLan (802.11 A, B, G, etc.) and you can also check the WLan channel and improve the signal
    -Disable the Wlan Card saving
