I own a copy of Windows 8 Pro 64 bit...I never faced any problem with the 32 bit copy but 64 bit windows has the following issue -

Without Internet sharing, starting a hotspot, I connect my iPad to the hotspot and assign it a static IP and it works and provides the device with a static IP.

However when i turn my 3g stick to share internet connection, the device takes ages to get an ip and it isn't static. Rather an IP obtained from DHCP. Also, it never completely connects to the network and hence there is no access to internet or other files.

Is anyone else facing similar issues ?
