Not just 'close to'. The wifi channels are very fat, and every channel extends .01GHz in either direction from its center. But more importantly bluetooth uses the exact same 2.40-2.48 range. It tries to minimize interference by frequency-hopping, but it's guaranteed to overlap 2.4GHz wifi.
So it's probably okay to use for a wireless mouse/keyboard but continuous sound output is a no go? Just seems like a bad design I mean the computer doesn't even have an ethernet port so to have wifi + bluetooth as a suggested combo/function and it doesn't work... haha
