So I have a really strange issue. Today all devices were connecting to the network with internet access all fine and dandy until a single computer wired directly into the router suddenly lost connection. We have two other devices also wired into the router (another desktop and a laptop). Those two other devices had no internet issues at all.
So I was doing the normal troubleshooting for the single device and trying things like rebooting and then trying ipconfig /release, ipconfig /flushdns and ipconfig /renew. It wasn't working and I noticed that the computer was not picking up dns servers at all when I checked ipconfig /all.
Then suddenly the laptop's connection stopped. I hadn't done anything to it's configuration at all, it simply lost connection as the first desktop had, only it happened a good hour later. Curious, I then checked all our wireless devices (2 phones and a playstation 3). All wireless devices have no internet connection, and I don't know when they lost connection.
I then power-cycled the modem and the router. No change, the only device that has connection is a single desktop running Windows Vista (the device I'm writing this post on). I thought maybe the router is busted, and I swapped the ports that the desktops are wired into on the router. No change there either, the windows vista desktop regained it's internet connection with the windows 8 desktop remained on the network but unable to access the internet.
So why would all devices but one loose internet connection but all have a connection to the network? I can even share files between the Windows 8 desktop and the Windows 7 laptop, but neither can access the internet. Not a single change had been made to the internet connection on any device or on the router. Maybe it's worth noting that the only device that can get internet access is indeed the "host" computer who's MAC address is the one tied to our cable modem.
Statistical recap:
Cable modem
3 devices wired into the router:
1) Windows Vista - host computer, has connection even when swapping the port in the router that it's wired to
2) Windows 8.1 - desktop that was the first observed to loose connection
3) Windows 7 - laptop that lost connection about an hour after the desktop lost connection
Myriad of wireless devices connected to the router:
- Phones, playstation 3, wii, kindle fire all lost internet connection at an unknown time
