Yet another 'DNS not responding' thread

[Entity79]

Hello,

I recently got a new cable modem when my Comcast cable service was upgraded to HD, and ever since, I haven't been able to get my Dynex WG-RTR wireless router to connect to the internet.

The way I had it set up (and it worked fine until today when the modem was replaced) was as follows:

[Cable Modem]--------[Switch]------[Wireless Router]

IE: I had my wireless router plugged into the switch along with my desktop and Xbox 360.

But now, it doesn't work. I've tried resetting the modem and router, my PC, and the switch as well. It seems I can only get the router to work if I take everything out of the switch, plug the router directly into the cable modem, and plug the other devices into the router. I'm at a loss what to do now.
But here is my ipconfig info.

Thanks in advance for any help.

Your set up was incorrect and as you found out it works when you put the switch AFTER the router which is how it should be.

It goes cable modem>router> switch, you plug the cable modem's WAN port into the WAN port on the router then plug the switch into one of the LAN ports on the router.

Well, it had worked just fine up till the cable modem got replaced.

It might have worked with one modem but the way you had that switch isn't right and will cause problems, the switch always goes in after the router. You won't have any problems when you connect everything as I described earlier.
