Wireless internet dropped, yet LAN works
I have seen this question asked before, but have not found a definitive explanation of how the scenario is even possible. What could possibly cause the internet to drop out while the LAN connection continues going strong? To be perfectly clear: when I lose internet connectivity, I can connect up to my router's admin page and ping (for example) google.com just fine. To fix the symptom (and not the root cause--what is it?), I disable and re-enable my adapter. What is a permanent fix for this frustrating issue? Additional information: NIC: TP-Link TL-WN851N, version 2. drivers installed: TL-WN851N_v2_100505, published 5/5/2010 Router: Buffalo WZR-HP-G300NH, firmware version 1.74 OS: Windows 7 Ultimate amd64, fresh format Possibly useful Event Log entries: Error, TermDD, The RDP protocol component X.224 detected an error in the protocol stream and has disconnected the client. Warning, WLAN-AutoConfig, WLAN AutoConfig service has successfully stopped Warning, DNS Client Events, Name resolution for the name www.totse.info timed out after none of the configured DNS servers responded (this one is repeated often, for different domains, and occurs whenever my internet gets dropped) Warning, Tcpip, TCP/IP has chosen to restrict the scale factor due to a network condition. This could be related to a problem in a network device and will cause degraded throughput. Warning, User Profile Service, Windows detected your registry file is still in use by other applications or services. The file will be unloaded now. The applications or services that hold your registry file may not function properly afterwards. Error, Kernel-EventTracing, Session "Circular Kernel Context Logger" failed to start with the following error: 0xC0000035 If I had to guess, I'd say these errors all point to faulty drivers. However, I'm using the most updated drivers available. If the answer to my question ultimately ends in, "you're screwed", I won't be surprised, but I also won't be happy. :( Even if the answer really is, "wait until updated drivers are available," could someone with expertise please explain what the root cause is, whether or not it's in the driver code, that would cause internet to die while the LAN continues going strong?

http://support.amd.com/ . Visit the maker of your processor's website, to be certain that you have the right motherboard and chipset drivers for your machine. If they offer no "7" drivers, you can probably use the server ones from 2005 and upwards, as they will be based upon the same h.a.l.s and kernels. It sounds to me as though there is a definite driver problem, as well as possibly some misconfiguration in user accounts and priveleges, because of the error reference from the user profile service. This usually happens when you are logged into physically seperate consoles in the same domain at the same time. When was the last time the machines were defragmented ? The fragmentation of files and folders will corrupt data over time, also."While there is NO SUCH THING as a WRONG QUESTION, the EASIEST THING TO GET in the world is a WRONG ANSWER!" 15 years of hands-on-how-to; I "DO" WINDOWS !!!

You're not likely to get definitive answers. To me the symptoms imply a problem in your router traffic. You can lose the "internet" outside of the router, on the WAN. THis could be caused by your ISP, the router, the DNS server, and temporary problems with your NIC or yes, your drivers. If your LAN continues to operate, even though you lost the "internet" keep in mind that the two exists as separate entities. If your LAN continues to function (best tested by transferring data between computers on the LAN or sending something to a network printer, but you lose the internet, it tells me, that the problem is NOT your adapter, or drivers. It is the WAN connection. If you can transfer files or print something on your LAN, talk to your ISP and/or router manufacturer. Recycling your adapter to correct the problem may just be a conincidence, OR may simply be the trigger to reconnect to the router, or beyond. Eb

What baffles me is that I only lose internet on my computer. The router maintains internet connection: I am able to ping web sites through its diagnostic page.

Thanks, I'll try to update my chipset drivers. I'm using an Intel Core 2 Quad in a GA-P35-DS3R. I'll try the chipset drivers from http://www.gigabyte.us/products/product-page.aspx?pid=2543#dl. The problem hasn't occurred for about a day now. I notice that it seems--although this might just be coincidence--to occur more frequently with heavy network traffic, like when I'm downloading something.

i DIDN'T MEAN THE FIRMWARE OF YOUR ROUTER OR CARDS. I meant that the chipset on your motherboard in your computer may be the culprit, if the drivers for your built in nic aren't right. Any and all other nics and routers still communicate with your actual processor on the motherboard, through that same access, whether it is the one you use or not !!! Don't get them from anyone but intel for your motherboard !!! http://downloadcenter.intel.com/ . They have a nifty little driver crawler from husdawg.llc that will download and run within your computer, and end up with a linked listing of all the drivers you need to install. It is also able to tell the ones that are installed, and whether or not they are current for your system. THIS IS MY ONLY RECOMMENDED LINE OF APPROACH FOR THIS PROBLEM, AS ANYTHING ELSE WOULD BE AT BEST A GUESS, WHICH I DON'T DO....AND, THESE DRIVERS ARE FREE TO DOWNLOAD AND INSTALL, AND WILL AFFECT EVERYTHING YOUR COMPUTER DOES...and, as with any other installation process, be sure to restart the computer afterwards so the new values get written permanently into the registry."While there is NO SUCH THING as a WRONG QUESTION, the EASIEST THING TO GET in the world is a WRONG ANSWER!" 15 years of hands-on-how-to; I "DO" WINDOWS !!!

NTauthority, I realize this is an old post but I hope you can provide some feedback on the original problem with the following differences: -Only Windows 7 clients on WiFi seem to be affected (using Ethernet Cat 5 has no problem) -An apple device (iPhone4) and XP client (same model laptop as the two Win7 clients) both able to hit the Internet Does this sound like a wireless card + Win7 issue? If so do you think a driver update would resolve it? Thanks
