I have an Acer Aspire 7551 with no internet connection. in device manager under network there is a broadcom 802.11g that's OK. An exclamation sign by Teredo tunneling pseudo-interface and an exclamation sign by wireless network card. there is no indication of any internet, wired or wireless in the righthand corner of the process line. the control panel says hardware missing when I try to establish a new internet connection. I sure hope someone can help me because i have no idea what's wrong
