PS. To trolls:

So sorry about you guys talking here about nothing helpful and wasting your time.

You also waste someone's else time who are going through all that sh... searching for solutions and advise.

Really sorry, but if that is your job....

Do not be sorry, you are absolutely correct, and my apologies. These Forums are here to help users such as yourself, but unfortunately, by the very nature of online Forums, tempers get strained and words are exchanged that shouldn't be. Thank you for chastising us and reminding us why we are here for in the first place.

Cheers and Happy Computing 🙂

Just received my new iPad mini 4. Wifi Problems, haven't activated cellular yet, at times of the day its great and at times almost zero speed. Cannot download any apps. tested speed on my computer during these times and I'm 59mbs / 6mbs respectfully. Mac works great. checked out my apple time capsule router and everything seems fine. Any help would be great. ***** to have a 1000 dollar piece of equipment that cannot download an app.

You don't say which OS is was supplied with, but if it is brand new then the solution is simple - contact whoever you purchased it from and tell them it is faulty so you want a replacement

A new iapad mini has a 14 day no questions asked refund. Take it back to the store to be looked at and replaced if necessary. That is not normal behaviour for any device running iOS9

Thank you. I will contact apple. I live in Wyoming with no store so I will have to mail it in I guess.

Give them a call, they will probably courier a replacement (and the driver will collect the faulty device)

I understand from a Forbes article that ios9 reverts back to ios7 WiFi protocols. As upgrading to ios9 is fixing the problem for many people could it be that ios8 is at least part of the problem?

When I upgraded my iPhone 4S to ios9 it didn't immediately fix the problem but having applied the magic hair dryer/freezer trick yesterday it burst back into life after I reset the phone. Maybe some flags have to be reset in the hardware as well as upgrading to ios9.

In the past the hair dryer/freezer trick would only work until my phone warmed up then the WiFi would grey out again. Now it seems to work all of the time and the phone doesn't seem to get so hot in normal use either.

I think ios9 should be added as a likely fix for the problem. After all, isn't that why Apple have gone back to ios7 WiFi protocols?

A little late to the "ball game" here? Regarding DiscoveryD, the networking routine used in iOS 8, please see my post on Page 219, Sept 17. (Gordon Kelly got some of his info from me).

Then please read my post on Page 220. I offer a list of suggestions for Wi-Fi issues. The #1 is: Upgrade to iOS 9.

https://discussions.apple.com/thread/6546549?start=3285&tstart=0

And yes, I know there are some having issues with iOS 9 now as well, will always be so with any iOS or Android or PC or Mac.

Cheers...

So, in IOS8 there was discoveryD, which you point at as the cause, the proof? IOS9 replaced discoveryD with a different method and all is well.

But

ios9 wifi not working

I upgrade a few days back and after about a day, I too lost my WIFI connection, and was unable to get it back. I started with the basics (router reset; reset network settings in iOS; forgot network, etc), all to no avail. Also frustratingly, my wifes' phones which is still on iOS 8.4 wasn't having issues and all of my other devices were connected no problem.

Isn't that the exact opposite of what your theory states?

Why is that?

It would appear that the problems being reported with IOS9 are different.

With IOS8 the device would connect to Wi Fi, but the connection kept dropping out. With IOS9 people cannot connect at all

Old-chap, don’t worry about it. Of course you are correct about iOS 8 having issues with the Wi-Fi routine; whether someone wants to believe it or not is their choice. As I summarized on page 219, Apple reverted back to mDNSResponder for a simple reason, DiscoveryD (DD) did not work as Apple had hoped. As I also mentioned, Apple did not do this lightly. They did it because they believed that mDNSR works better than DD; they would not have replaced it if they felt otherwise. I actually give Apple a lot of credit, first for trying to fix DD and secondly for reverting back when fixing was not immediately feasible. The mDNSResponder that is now used in iOS 9 is somewhat tweaked from the version used in iOS 7 and Mavericks. This “tweaking” was necessary to incorporate the new features of iOS 8 and 9. Unfortunately, as with any software some issues are bound to arise. For instance, in iOS 9 some are reporting that hiding the SSID causes their connection to drop, a new issue I was not aware of in iOS 8.

Only a sharp programmer can understand why DD worked on some devices and not others. Some programmers are self-taught but the majority go to a technical school for years and continue on from there. They learn programming, specifically the languages Apple uses, and only then can they delve into the intricacies of the DD code (DD was written in C++, not one of Apple's commonly used languages). Apple has a myriad of expert programmers, some of the best and brightest in the industry, and like I said above, these programmers did not replace DD for the "fun" of it, they replaced it because there were bugs they could not fix after 9 months of effort. I attempted to give a layman’s explanation about the reasons in a previous post, but for a layman to understand this, is akin to you and me understanding brain surgery. And again, there will be some who will chose their own explanation regardless of the facts. Pope Paul V did not believe Galileo and some here will forever believe that there was nothing wrong with iOS 8, their choice.

Thanks for your posts on this thread. I and others no doubt appreciate them. 🙂

Thanks for comment, I'm going to follow the advice you were given by Mandy (shame it got deleted)

While (fortunately !) I am not having any problems with IOS 9, I accept that many people are - same as happened with IOS 8 in that not everyone had problems. Shame some others cannot accept that

1. Posts get removed, unfortunately, when some posters take the whole tread off topic and break the Terms Of Use as happened, so all subsequent replies to the offending posts, good or bad, are also deleted. That is the way it has always been and sometimes is sadly the aim with a certain poster who was here.

2. I don't understand why you are taking advice on fixing something that you then say you are not experiencing?

Cheers

I know what oldchap is referring to, whilst the post may have been deleted I (and no doubt lots of other users) have the e-mail giving full details so he is not speculating or claiming virtually anything

It was simply advice that was given by 'Mandy' who is manager of the moderators

To old_chap and insider: I know what you mean... please heed the suggestion offered by the mgr., it is a good one and works very well indeed - just focus on sharing technical information which is appreciated by most. I am glad that iOS 9 is working for you. I am now on 9.0.1 (out yesterday) and all is well from my end, happy to say...

Regards,

🙂
