Wondering if anyone else has run into this yet. Browsing the internet, when all of a sudden all the computers on the network loose the connection to the internet, both wired and wireless. I logged into the router, and checked the connection status and I show an active and valid connection to the WAN, although when I checked the statistics page, the WAN is dropping recieved packets.
I released the DHCP connection and renewed, with no effect. Next, re-booted the router, with once again no change. On a whim, I put my desktop connection into the DMZ on the router, and instantly not only does my desktop re-connect to the internet, but so do all the other computers still behind the firewall. I removed the desktop from the DMZ back behind the firewall and everything is back to normal.
Here's my configuration. 2 Desktop computers (one XP Home edition, one Vista 64bit) and 2 Laptop computers (one XP Home, one Windows 7 Home Premium), and an Xbox 360. All systems are fully up to date with all patches and service packs, and the Vista machine was the one used briefly in the DMZ. Laptops are usually connected via wireless, with all others hardwired only.
If anyone has a clue as to what is causing this, I'd love to know. My dad is not as educated as myself or my brother are with computers (he admits to being technically challenged with this sort of thing) and if this were to happen when I'm not home I know this will just frustrate him. The router ran for almost 11 days before this occurred, for your information. Thanks in advance for your help.
