I am in need of some serious help on configuring routers from a modem.
OK so here is the deal.
I have Charter Cable internet/phone service at my store. The internet modem doesn't have enough ports so i connected a regular D-Link router (not wireless) to the internet modem so than i have enough ports to run all my machines. All my machines such as FOOD STAMP/WIC and a machines that prints PIN number for Boost, T-Mobile etc works (until this stage, everything is working fine). I had to add couple of more machines to my network and i needed few more ports, so i decided to add a wireless N router (Linksys) to it. I hooked up my Linksys wireless N router to the Regular D-Link Router (at this point, D-Link is the main router and Linksys is the 2ndery router) Everything was working fine up until few days back. My machines stopped working, there was no connectivity to it and so as my computer. Somebody told me that you need static ip's for your little network, so i ordered Static ip's from Charter and tried to configure both routers myself.
1. I hooked up D-Link router to my computer and configured the router through Static ip's.
2. After i was done with D-Link, I hooked up my Linksys Wireless N router to my computer and configured it with Static ip's.
3. I hooked up D-Link router to my Charter Internet Modem and from D-Link Router, I connected Linksys router and through linksys router, i hooked up my computer. Everything was working fine up until this morning. All of a sudden, computer stopped working but not at the full. Sometime it will have connectivity and sometime it will not.
Note: I haven't configured the network connections in my computer yet because i don't know which IP i should use? However i tried changing the network connections and tried different IP addresses in there but its not working.
I know i am doing something wrong but i can't figure it out.
Now some more info:
D-Link router, i am using it as a router not as a switch even though somebody told me that you should use your regular D-Link as a switch and make your Linksys wireless router as a main ROUTER, i tried that but it didn't work, none of my machines worked with this setup (i disabled DHCP in my D-Link router to use it as a switch). I even bought a netgear 5 port switch for the setup, i made my Linksys the primary router and than gave the connection to the Netgear switch but there was not connectivity.
I am sorry for this long a*s question but i really need help to solve this situation.
