I live in a small hotel that provides WIFI Internet service. I have 3 - 2TB Network hard drives I also want access to. I have a Cisco E2000 Wireless Router that they are connected to. For the past 3 months I have jumped the connection back and forth as needed (i.e. Internet to Hard Drives) because I can't seem to connect to both at once properly.

I tried connecting my Cisco Router via LAN cable and wirelessly to the Hotel WIFI. They both appear in my network connections but whenever the LAN cable is plugged in, the internet is gone. I get a DNS error every time. When I pull the cable, the internet comes right back up. Very frustrating. I'm using a laptop with WIN 7. Is there a configuration change I can make to the LAN connection that will prevent this?

Make sure your two networks are on different subnets, or in other words the IP address ranges are different. If your router providing Internet access gives you an IP address in the 192.168.1.X range, setup your LAN router to provide addresses from a different range (say 192.168.2.X assuming a netmask of 255.255.255.0).

I'd say give the private LAN an uncommon private address space like 192.168.50.0/24 or 172.16.1.0/24, and then make sure that the local router is not trying to pass itself off as a default gateway. –  Sammitch Sep 21 '13 at 0:00
    
I plugged in the new subnet and netmask. The internet is up but access to the local router is not working. What should I put in the section for default gateway? –  Phillip S. Sep 21 '13 at 2:14
    
Disregard. I figured it out. I changed the default IP on the router itself. I had been trying to do it thru windows. Thanks heavyd!! –  Phillip S. Sep 21 '13 at 3:16
