Hi, I've just bought a Dell Inspiron mini 10 for only 1 week and my wireless network has been working perfectly in my house, my school, and even mcdonald until today. I was trying to go online in my college as I always do. However, the Wireless network connection icon has shown that it has Limited Or No Connectivity.  I've tried to repair the connection, disable and enable the network, restart my computer, reinstalled my WLAN drive, typed in the internet IP, subnet mask, Gateway, and all the internet detail myself, and even tried system restore at last but nothing has worked. I first thought that it was a problem of the school internet but not mine. However, my friend has easily connected to the internet with his sony laptop unlike mine. And also, after going back home, I could connected to the internet through my router, so I am just wondering if it has appeared to any other Dell user and what I can do to fix the problems, Please let me know, thanks!!!
