Internet dies when desktop crashes? PC wired to RT-N16

    I have a RT-N16 with Toastman that I connect my desktop PC to via wired Ethernet. Anytime the desktop blue screens and locks up, the Internet dies.

    This makes no sense to me, why would the desktop affect Internet when it's only interaction is through the router? The router still accepts wifi connections during this time, and you can access the admin from a wireless device, but Internet does not work and you can't access the router admin remotely until you restart the desktop computer, at which point Internet is restored. No need to reboot router or modem or anything.

    I still need to troubleshoot why the computer crashes, but I assume its an issue with my webcam and Windows 8, as I use ustream as a free pet cam to watch our dog while I'm away. But it baffles my mind why a lockup could affect the router's connection.

    Any ideas?

    Hm my idea would be to ping Google at the Moment the Desktop crashes. Maybe also try to run a wireshark caputre to inspect the Situation.

    Can you just open cmd and type Tracert Google.com? Post a screenshot or rightclick-copy and paste it here ;)

    Try a different ethernet cable, and a different switch port on the router. Otherwise, inspect the BSOD.
    If you have the possiblity, connect the Win8 PC over wifi instead of LAN.
    Update your LAN drivers (do not use the ones Windows finds itself, get them from the manufacturer).

    Changing Ethernet cable and router switch did not work, it crashed again today and internet is down. Funny enough, it only seems to crash when I'm streaming from ustream. Next step is to research the reason for the BSOD, but I still have absolutely no idea why the desktop client going down would affect the router!?

    Malware advertising itself as an http proxy server on your network that's hosted on that PC? Try configuring the other systems to never use a proxy server, to always directly connect to the internet, and see what happens.

    Otherwise, is there something special about this system? Does your router point to it in any way? Under DNS perhaps?
