here's what my connection looks like (shaw) cable internet goes through modem, then through my D-Link DIR-615 Wireless N Router, then a wired connection goes to my computer and a wirelss connection goes to my sister's computer my problem is that, both our computers like to lose their internet connection at completely random times, requiring us to disable and re-enable the network connection in Control panel/Network connections funny thing is, we only lose connection to the internet, but Not the connection with the router, and the lights on the router says it's online i'm a Bittorrent user, which might have something to do with it, as my connection tend to die when i leave my PC on to torrent while i'm at work, or doing heavy browsing while running torrents in the background hope anyone has any thoughts on this? thanks

When you lose the connection, open the web interface to the router and check the status. Also, make some ping tests. Ping google.com and ping 151.198.0.38

ok i did what you said and found out something i didn't know before i cannot ping google, infact i can't even ping my router, and i can't access my router's interface it seems that though my router shows on it's panel that my computer is connected and there is activity (the panel connection lights up), i am infact not connected so it might be my network card on my PC's end, but i've actually tried a few other network cards i have lying around and they all have the same problem: disconnected from the internet after some heavy traffic is there anywhy to find out for sure which part of the connection is broken?

Are there any other PCs on the network? If not, connect the PC directly to the modem. If it still happens, maybe you can connect it to a friends router. If it still happens, the problem is in your PC. Also, click start, run, type eventvwr.msc and press enter. Look at the error messages in all three log files.

something suspisious in the log is this m4cxw2k3 service that "Driver has encountered an internal error" what does this mean..?

That's the driver for your DLink adapter and the answer to your problem. Look for an update. m4cxw2k3.sys information Path found: C:\ WINDOWS\ system32\ drivers\ m4cxw2k3.sys Version: 8.39.4.3 built by: WinDDK Company: D-Link Corporation Product: D-Link DGE-530T Gigabit Ethernet Adapter Description: NDIS5.1 Miniport Driver for D-Link PCI Express Ethernet Controller

it's been a while, but my problem has not gone away After updating my driver for my Dlink adaptor, the same error is still occuring frequently everyday in event viewer, whenver the error occurs, i would either lose connection, or have very laggy and slow performence in networks I've also tried taking out the adaptor completely, and run my onboard Lan adaptor. I still got frequent event 101 errors, although not on m4cxw2k3, but on this yk51x86 file
