Turn off n Mode in your router if it supports it, but even then wifi will be somewhat short ranged, you have to get to a closer range, yet somehow after I accidentally broke down my mini (kept installing kexts without rebuilding cache which led to system errors), I managed to boot single user and fixed the pc during the process I fixed the wifi as range is now full but I don't how I did it.
Simply re-run my hack installer but chose install chameleon and extra to hdd, if you get boot0 error like me we have to wait for a fix or you could try what lester did.
QE/CI = a no go
Resolution over 1024x768 = Impossible for now but meklort is working on the patch (he told me it was low priority though.
PS resolution becomes clearer after you install the hd crystal driver as your graphics card is detected as hd with 700mb vram I posted the driver in a different thread.
