    Keep losing internet connection on Windows 8


    My laptop keeps losing internet connection. It appears to remain connected to the router but not have actual internet connection. I have pinged the router thousands of times and have no packet loss so I don't suspect that is the problem. I've tried the internet connection on a computer running Windows XP, one running Windows 7, and one running Mac OS X and none of them have trouble staying connected, so it appears to be a problem only with this laptop.

    Does the machine appear to be online but the browsers won't go anywhere?

    Winsock entries tells Windows 7 how to access your network services. Additionally, your TCP/IP protocol can be corrupted. The TCP/IP protocol is a stack of 4 layers that includes several transport layers, but when this stack is corrupt you will constantly have connectivity issues.

    So to fix this problem is may work if you reset winsock and the TCP/IP stack.

    Copy/paste the following two commands, one at a time, into an elevated command prompt hitting enter after each one, then reboot your machine and test connection.


    Code:
    netsh winsock reset catalog
    (reset winsock entries)

    Code:
     netsh int ip reset reset.log hit
    (reset TCP/IP stack)

    I solved the problem, at least temporarily. It seems that my router/modem/computer combination doesn't like WPA2 security. After switching to WEP, I no longer seem to have the problem and my download speeds have increased ten-fold. Is that normal, or is something wrong with either my modem, router, or computer?

    This would indicate that the driver for the wireless NIC needs to be updated or the firmware on your router requires an update.

    Windows update is also a good place to check for updates on your Lenovo.

    WEP security isn't secure at all and it also limits your wireless speed, I'm surprised that Windows 8 will even work using WEP security.

    I'm thinking it would be a problem with the router since I have experienced the problem while using WPA2 on multiple computers.

    I'm not sure which driver to download on Lenovo's site since I don't know what wireless card the computer uses. The only thing I could find in Device Manager was "Broadcom 802.11n Network Adapter"

    I see two possible drivers there for your system, both Intel drivers, 7.5.1007.26 and the 15.5.0.42, Windows won't allow the wrong one to install.

    You shouldn't be having any problems using WPA2 so something is off there, resetting the router using the reset switch would be my first option, updating the firmware second option.

    I had the exact same problem as the OP. My laptop is a Lenovo Ideapad Y500 with an Intel Wireless-N 2230 card.

    I registered just to thank you. More people need to know about this tip!

    Thanks a lot!

    That's good nuclear, too bad the last guy never reported back in to let us know what fixed his problem.
