Need Help W/ Linksys EA6350

[ Edited ]

Hello,

 

I'm replacing a Linksys WRT54G wireless router, in the server cage, at work. This is because they've been renting equipment from a local IS/IT support place, and no longer want to pay an arm and a leg for it. My boss purchased a brand new Linksys EA6350 (AC1200+). He also purchased a new Cisco SG112-24 24-port switch.

 

The original configuration for the network has a Hitron CGMN-2250 cable modem (with Comcast service), which then is connected from the Hitron's LAN port connections to the Linksys WRT54G wireless router's "Internet" port. This then goes from the WRT54G's LAN port connection to the Cisco SG112-24 switch.

 

I'm unable to replace the Linksys WRT54G router with the newer EA6350 model - as I can connect to the router, but not to the internet. I've tried resetting the EA6350, and basically setting it up to mimic the settings on the current WRT54G, all to no avail. No matter what I do? It simply won't connect to the internet, although the port lights show activity on both router and cable modem when connected.

 

I was able to get the EA6350 to connect to the internet, but only when I left the old WRT54G in place and simply used a network connection in the office to provide it internet service, while connecting to the router itself wirelessly. For whatever reason, it won't recognize an internet connection by itself, i.e. it won't connect directly to the cable modem, and it won't connect or recognize any internet connection unless I connect it to the switch and leave the WRT54G in place.

 

I can set it up, while it's connected to the internet from behind the WRT54G, and use the internet and internal network just fine. But the minute I try and install the EA6350 where the old router is/to the cable modem directly? The internet dies, while the network connection remains. I'm starting to get pretty frustrated.

 

Here is the ipconfig from the network, while functionining, using the old WRT54G router:

What am I doing wrong? Is there a better way to set this up? I'd appreciate some input, before this router ends up at the bottom of a large body of water...
