Weak wifi

I received my iPad Mini just in time for Christmas and the device was updated to 6.0.2 before I really had a chance to use it. I can confirm that I too am experiencing very poor wifi connectivity in comparison to other Apple and non-Apple devices. This includes the original iPad, a number of iPhone models and non-Apple tables and laptops. I strongly doubt that this is a software issue, but rather a hardware design fault. I'm going to reassess my purchase pending comment from Apple Support Representatives.

change you WIFI model to 802.11n only 5GHz by the airport extream be better !

i need help! my ipad is having a problem~ i cant open my ipad because of this saying "Not enough storage -> this ipad cannot be backed up because there is not enough iCloud storage available. You can manage your storage in settings." if i click the button close it wont close and if i click button settings it wont go to settings as well. What will i do? how can i fix it? here's the pic of it.. need your help anyone?

You have posted in a thread which is totally unrelated to your problem but try this:

Reset your iPad.

Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).

I have the same problem. I tried to change my wifi encription from WPA2 to Open, but I still have wifi problems.
