Hi, before i start I am not very computer savy. I am able to follow directions and learn fairly quickly, so please be patient. Our family recently switched our internet services from comcast to at&t (cheaper/faster). I spent several hours working on getting the router/modem to work. I started out on our main desk-top computer where everything is. I connected my modem to the router and then the router to the PC tower Ethernet Port. It told me i did it wrong, so i went back and just put the modem directly into the ethernet port (it is a DSL modem). I got it working and asked some one from the at&t chat area tech support how to set my router up. Then they told me i had to go to my modems IP adress and change PPP setting to the computer/router setting, and that messed everything up. this is where i spend the majority of my time lastnight trying to undo everything i did. Well now i have my modem and router hooked up just fine (and properly, turns ou I did do it properly the first time around) and I think i have undone the PPP adress but im not sure. but now when i try and connect my laptop wirelessly i get the "local only" connection and i cant acess the internet. I have gotten a "network error" that pops up and says the following: "Another computer on this network has the same IP address as this computer. Contact your network administrator for help resloving this issue. More details are available in the Windows System event log" I have contacted at&t again, they walked me through how to make sure my DNS and IP address were aquired automaticly (they are and were). And then they told me it was a computer setting issue and they couldnt help me (but thier expert 15$ a month tech support could). I have an Acer Aspire 5335, Running Vista Basic 32-bitOS, with an Intell(R) CPU. the desktop everything is connected to is an Emachines ET1641-02w, running Windows vista home premioum 32 bit OS. My modem is a Motorola "style: MSTATEA" and my router is a Cisco Wireless G broadband router with power boost by Linksys I have at&t DSL service the second option im not sure what its called, it is the second fastest one they offer. and my modem/computer/router set up is currently: Ethernet Port 1: Ethernet port from router to desk top computer Ethernet Port2: Ethernet port from router to modem Green Phone line from Modem to phone jack. I was looking at the at&t website lastnight about 3rd party routers and it said that for a linksys router i had to plug the modem directly into the "internet" port on my router, i tried that and i was unable to get internet? And i have noticed that when i turn the desktop PC off the "internet" light on my modem goes off what does this mean? I'm sorry this is so long im not really sure how much information to give. I hope it is in the right place, if it is not I apologise.
