I have my Windows 7 computer and my printer connected to my Cisco router. Printer is connected wirelessly to the Cisco router. Computer is connected with a cable. I have my router connected by cable to an Arris modem from my ISP.

Win7Computer --------> Cisco Router -----------> Arris modem
i
i
Printer-------------------------->

My internet is currently working, and I can currently print on my printer. But on a daily basis after hours of nonuse my computer loses the ability to contact the internet and rebooting the router doesn't fix.

My default gateway in ipconfig is 192.168.0.1 I can successfully ping this address, and I can access it in a web browser. Only problem, this address brings up my Arris modem, not the router.

One of the two IP addresses should be 192.168.1.1 . I can't successfully ping that address, nor open it in my browser. It tries to connect forever, then tells me the site can't be reached, it took too long to respond.

I have previously been able to access and adjust the settings on the Cisco router, in my browser.

When I view full map in Network and Sharing Center, I learn that DorasRouter, the Cisco Router, has the IP address 192.168.1.1, MAC address c8-d7-19-ef-f7-31 It and my computer are allegedly connected to a switch, which gives me no information. The switch is connected to a GAteway, which is the Arris modem, IP address 192.168.0.1 .

ARP-a lists my computer's IP address, the Cisco router's IP address 192.168.1.1, dynamic, and the Arris modem at 192.168.0.1, dynamic.

About once a day, usually after not using the computer for a few hours, I lose access to the Internet and often nothing but rebooting the computer will restore it, so something is the matter.
 
Solution
It depends what you are trying to accomplish by placing a switch between the modem and the router. Normally you would never to that the pattern should be

isp--modem---router---switch

Is the modem a modem/router? If so, it is a gateway modem, meant to have the combination of both. What I've done, I've change my default gateway to 10.10.10.1, that way, there is no way to confuse the two. Try that, and let us know what happens.
 
^What bill says. By placing switch where you have placed it, for unknown reason, you have created this situation.

You know you are running 2 subnets, 2 DHCP, this create issues. If you are able to configure Cisco as Access Point, you will run on a single, simple subnet, single DHCP with no issues.
 


I agree. Also turning that modem into a bridged-only modem where it doesn't give up a subnet or DHCP could help as well. It sucks that modems doesn't have the ability to turn the router portion off.
