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.

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:
[B]netsh winsock reset catalog[/B]
(reset winsock entries)

Code:
[B] netsh int ip reset reset.log hit[/B]
(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.

I've had the problem on my windows 8 box for some days; applied the reset Winsock and TCPIP entries (twice), and SO FAR, holding my connection right now. Fingers crossed (am still working via the Android tablet and keeping an eye on the Win8 laptop, for now). Not seeing je thumbs up icon on Andoid, but if all holds, will sign back in via the working laptop and give credit! :)

I had a weird thing happen that's worth mentioning. After reading an article on security, i wanted to make sure that router settings could only be changed by the computer connected using a cable. I used Firefox to open modem settings. Everything was okay, so I closed the browser. That night I started having connection problems on two laptops. One finally quit connecting at all.

Repeated the procedure with FF to make sure I hadn't changed a router setting the first time I went in. Problems persisted. Went back in a third time, but this time, when I quit, I LOGGED OUT. Problems solved.

Even though it might be bothersome, disabling DHCP and setting up network settings manually helps in 95% cases. It is normal for wifi to loose signal for a second, but in order to reconnect, it has to find the wifi, verify it, get a new IP and that takes time and if it has lost the signal once, it can loose it again, so people might end up in a never ending reconnecting loop. If it is set manually and the connection is lost for a second, you can get back on track in a matter of seconds, hitting F5/refresh button in a browser will usually do. :)

I'm back. As reported, resetting the Winsock and TCPIP helped a great deal, but still the external IP disappeared (on my network metering gadget) and the "Page cannot be displayed" error was back, no apparent IPV6 connection, all on IE.

Yet. I was doing some DLing of a router firmware update (while I still had internet, and to investigate the problem further by eliminating a router firmware problem in case it existed) and the FTP based download failed. The online support chat for D-Link suggested I use a different browser because apparently IE (on W8?) was known to have occasional problems with refusing FTP I cranked up Chrome in background and was successful with the FTP DL.

All this is background. I did some further testing (to avoid a) resetting all my Windows Network settings to default and b) messing with the router some more). Strangely, even if the external IP disappeared (on my network metering gadget) and the "Page cannot be displayed" error was back on IE, I could access the outside world via Chrome! So the router was safe from my finagling.

In the end, rather than continue to be irritated with the IE and network gadget and work constantly (for other reasons) on Chrome, I finally implemented the WIN 8.1 DL, reinstalled my network printer, and my Gadget pack, et voila, WIN network settings cleaned up (culprit, in the end, for all of this).

Oh, and to be on the save side, in my router interface, ensured my Reserved (not Static) IP addresses were intact, once I could get back to the Admin panel via web interface. I have Network filtering by NIC address and Reserved IP addresses for all my household networked 'devices', including a Pogoplug with several HDDs attached, which is ACTUALLY where my problem started, after I tweaked SOMETHING in the network settings and I lost connection with the Pogoplug... sigh.

Hope this helps someone out there.
