I initially had no 'major' issues, just the random disconnects. Then two weeks ago I got home from work and the Mini wouldn't connect to my home network - which is a ~2009 Airport Extreme and 2x Airport Express plug-in extenders.
I did the usual stuff - reset network connections, reboot the Mini, unplug and reset my entire home network. No good ... kept getting the 'couldn't connect ...' message. Updated firmware on the Airports, and I already had 6.0.1 on the Mini.
Note that I have at least 15-20 other devices that all connect fine, including 3 other iPads (1, 2, and 3), Macbook Pro, 2x Sony laptops, old Dell XPS laptop, HP laptop, a few Nooks and Kindles, Kindle Fire and Fire HD, Nexus 7, as well as a Roku, Wii, XBOX, and a couple of iPod Touches. NONE of them have had the slightest issue. At all.
After talking to Apple a bit they pushed me to Airport support just to run through everything - and he ended up having me completely reset and reconfigure my entire network. Renamed each module, as well as the network, and also changed the security setting. It took a few days to finish because of school work my kids had to do meant I couldn't just shut down the network for a half-day. In the end, everything connected fine to the new network ... except for the Mini.
I got on the phone with Apple again - one problem is that the nearest Apple Store is >2 hours away by car - and eventually they agreed to have it returned for repair. While I waited for the coffin I played around with manually changing WiFi channels for the network to see if I could optimize signal. Again, no change for the Mini.
I got the box, but they didn't set it up properly with a dual ship/return label, which meant another ~45 minutes on the phone with Apple to get them to email me the PDF.
I sent it out, then a few days ago got an email that they couldn't replicate the issue ... and that they were sending it back. They sent it FedEx overnight ... but because of their direct signature requirement and the lateness of the notification email, what I should have gotten at 10AM one day I didn't see until 6PM the next.
And ... of course, it didn't work. And worse yet, unlike what they said, it was still on 6.0.1. So I was on the phone with Apple again ... and we started the cycle once more. After two calls they are doing another return, but there is of course the chance that they will simply send back the same one again.
As additional data of the singularity of the Mini having this issue, this week I got an iPhone 5. It arrived, I took it out of the box, selected to use WiFi, entered my password ...and it has auto-connected to my WiFi ever since.
Oh and I requested that they send me another PDF return label so I could use the same box they just sent it back with ... but it appears they are sending another return box.
I will likely have to call again and get a supervisor to ensure that they at least try a replacement for me ... just like they would if I was in an Apple store.
The worst thing is that I really love the iPad. I have called it my '80% computer', because I really DO the majority of stuff on the iPad, and found myself immediately using the Mini even more than the iPad 3 (the 2 and 1 I handed down to wife and kids).
Ugh.
Anyone else have something similar?
