Acer eNet Management Internet Disconnected

Question

I bought a new Acer Aspire 5315 on the weekend & the first night I had it I did not have any problems connecting to the internet. I have a router with 2 desktop computers & the laptop the first night connected to the internet no problem. On Sunday when I tried to use the laptop again it would not connect to the internet & tells me that my LAN & WLAN are disconnected?? I even tried taking my land line & put it directly into the laptop & it still would not pick up my high speed internet in my home?? Can you please advise I'm getting so frustrated & feel like this Aspire may be going back to the retailer for a refund before the 14 day return policy runs out. BTW I just bought this laptop Saturday May 24th, 2008 this past weekend...........
