Has anyone tried connecting a Windows 8 device to an N9 Wifi hotspot?

Recently, I have decided to get a Windows 8 tablet. I chose it over Android because the latter cannot connect to ad-hoc wifi (surprisingly, Asus Transformer pads can see and connect to the wifi, but not the internet). However, when I tried to connect to the wifi network created from my N9, the tablet could not connect. My 6-year-old MacBook and my sister's iPad 2 can connect without any problems, but the Windows tablet does not.

Additionally, after I try to unsuccessfully connect with the Windows tablet and then connect with the iPad, the latter establishes the connection with the phone, but cannot load any pages. After a while of trying to load a website, the icon on the N9 next to the iPad changes to the idle state (the one with Zzzz's).

Can anyone shed a light on this problem and help solve this issue? Thanks.
