Q: iOS 8 Wi-Fi problems

I hadn't thought about that - I'm out lots and rely on the various free wifi hotspots (Cloud, Openzone etc) How could all these change settings - I don't even know who I'd speak to. Imagine in Costa asking one of the Baritza to change DNS settings.......

Static IP addresses on public hotspots would nto work DNS may work.  once you set it up for the cloud or bt openworld or what ever it is called it should remember the static DNS.  you only need to change it once per network name.  i still dont think it is a DNS issue though as i used a 3rd party on mine and the issue was still there.

No changes need to be done at any coffee shops.. Static or not.. Doesn't matter..or any other place you visit.... Just your Apple device DNS... For the fools who know better.... Don't try it.. What do I care .. Live with the problem and don't try any ideas to fix it... HaHaHaHaha... ROFL.. And you see what you make of yourself.... Those who use it will see for themselves....  What is the response time of 8.8.8.8 and 8.8.4.4 on DNS benchmark?? Well Google fiber is 0.01 millisecond response time... You got one better??? I get a response of 27.635 milliseconds response time from 8.8.8.8... So is 27.635 faster or is 0.01 milliseconds faster in response??... HAHaHaHaha... Fools..  It worked before you broke it... I don't have any problems with Wi-Fi... Never have.. I think a few of you should read all my posts before comments...

I'm going to give it a try - but not being a techie (and don't want to get it wrong & make things worse!), in wi-fi settings, looking at the hub I'm connected to clicking the "I" shows lots of stuff, but against DNS is 192.168.1. 254

Is that what I need to replace?

Riddick - is partially right in my case... (OLD CHAP) the DNS is below the IP and subnet mask and router values..go to wifi, click on the one you're connected to.. now see the settings and go down to the DNS . click on it and change it for 8.8.8.8 or 8.8.4.4 or the Google open DNS..

RIDDICK

I tried so far 8.8.8.8 and 8.8.4.4 and although it seems to be more stable, it still drops the the VOIP capabilities. I also tried once the phone was on wifi (VOIP) to have something constantly streaming, like pandora.. well for three hours the VOIP stabilized.. I got calls and made calls and they were all on VOIP. I tried that with the DNS that is handed to me by my ISP (Comcast), and this did not work as well... SO.. we have pretty much ruled out router issues, IP issues, ISP issues and APPLE needs to fix the the "apparent timeout" which could be associated to the DNS.

keep in mind that apple was the last manufacturer to launch VOIP, this was done last fall 2014.. The reason they did not do it earlier was because they we have "facetime", but after much debate they felt they could loose customers if they did not add this feature. Well as I mentioned in my original post, The "post-Job" era of apple seems to have adopted more of a Microsoft approach which is to launch with minimal testing and let the consumer drive the testing and retroactively launch updates that fix the identified problems.. Apple did not used to have update after update after update, when they launched you could expect a much more stable and well tested product and o/s.. Its no surprise that the stock price has gone through the roof.. I'm guessing reducing the cost of testing has increased the profit margins... capitalism and such with a mix of conspiracy theory LOL...

SERIOUSLY.... APPLE get it together!!! EVEN Fortune Magazine has told you about the seriousness of this problem. for my part I'm looking into LG and android if this is not resolved soon. Keep in mind that my cell signal with ALL carries is a disaster, so I NEED VOIP to make and receive calls!!!

Yes... Change DNS... To number I posted... If it dont work... Just delete number you typed and your old number will show up if you back out one screen then come back... DNS needs to chaged at every new wifi. Internet provided gives you slow DNS to save their network load... Any else.. No changes need to be made at any network... However a DNS bench,ark test will show the best DNS server around you and who is fastest... Smart people ask questions and know whats going on.... Fools stand there and think they know whats going on.... 

Run DNS benchmark speedtest... I post links a few posts ago... Use fastest DNS you get from benchmark in your home router or wifi.... Use the google fiber ipv6 DNS on your iphone DNS.... Touch settings.... Wifi name you are connected to..... Touch blue i on riht side....then insert Google fiber ipv6 DNS. DNS must be change at every wifi you use.... And every new wifi you sign in for... Keep DNS in notes or email... Then copy and paste when you access new or old wifi Locations to change default DNS installed from internet provider.

Scottyboy, you said:  "I wonder if they will bother fixing the AWDL bug in iOS 8.2 or 8.3. Whenever I have AirPlay on in my network it causes the wifi to become quite erratic. Really annoying seeing as ios 7 exhibited no such issues."

I have been posting on this site for months and I have the same problem you mentioned above whenever I enable AirDrop on my iPad Air and iPhone 5. With AirDrop OFF I get speeds which generally match the ISP rate - with AirDrop ON my speeds drop to about 1 Mbps (sometimes as low as 0.1). Myself and others have posted about the article by Mr. Ciabarra in Medium that describes the bug in technical detail. It can be found by Googling "WiFried iOS 8".

Regarding the posts by Riddick, when I first called AppleCare about this issue months ago they suggested that I try Google's DNS, 8.8.8.8, and I did but this did not help. In fact I still have 8.8.8.8 as my DNS on my iPad and I cannot enable AirDrop as it will degrade my download speeds as mentioned above. A word of CAUTION here, as the Ciabarra articles states, when one changes anything in the Wi-Fi settings, DNS, APs, Forget Network, etc. one will get a temporary WI-FI bounce, i.e., speeds will be restored but this "fix" will not last for the reasons described by Ciabarra.

To answer you question I am hoping that Apple will fix the AWDL bug as this is the cause of the problems many of us are having but I am not confident at all that they will - was told by AppleCare that the "engineers" are very busy developing 8.2 for the iWatch so I am not holding my breath. Under Jobs Apple had a culture of "perfection" - now it seems that profits are the driving force and they are doing very well indeed. Apple will be replacing AT&T in the Dow Jones average and their stock keeps going up. This trend will not be sustainable if Apple software becomes unreliable, they will make a lot of money in the mean time but eventually it will catch up with them. Most people are either not having any problems OR are not aware that they have low speeds, I have two friends with dismal speeds and they were not aware of the issue as they are not techies.

My issue isn't really low speed (on my home network I average over 30mb) but the wi-fi signal keeps dropping out. I can be in the same room as the hub and the wi-fi will just disappear on my phone, all other devices are fine - my son has no problems on his Galaxy S5

My iPhone reverts to 3G which I've turned off as I started exceeding my data allowance & getting billed!

This thread has confirmed that it is a software issue (only started since I upgraded to IOS8) despite denials by Apple

Question for the techies, will changing the DNS do anything to improve reliability/stability of wi-fi?

Which DNS you use is irrelevant when the WiFi connection doesn't move any data.  Apple needs to sort that first in iOS 8. Only then is it worth tinkering around with the fastest DNS.

old_chap, I do agree with Riddick that changing the DNS will do no harm and will cost you nothing. Just do as he said and test it for yourself. He is correct that if you delete the new DNS number and leave DNS blank and then go back a screen and back again it will restore the DNS originally issued by the router. You can always put in 8.8.8.8, the Google DNS, this will not hurt at all but I doubt it will help, it did not help me. As I cautioned in a post above, you may get a temporary Wi-FI bounce as described in the article I mentioned but if so it will not last.

I never said it would fix the issue.. Did I?? What did my first post say??. I said in my first post maybe this would help... It only takes a few seconds to use Google fiber ipv6 DNS..NOT GOOGLE 8.8.8.8 or 8.8.4.4   I suggest you try ipv6 DNS over the Google 8.8.8.8 and 8.8.4.4 in your iPhone/iPad/iPod DNS.

You can use DNS lookup app from the app store.. try this DNS in your Apple device...

And Run DNS benchmark speedtest...  http://code.google.com/p/namebench/

Set number of queries to as many DNS servers you want tested.... Use those results and set your wifi and/or router installed from internet provider to the best two DNS servers near you.. (Both if you have them...... Run the test a few times so you know you have the best results...

I use a Netgear r6300 Wi-Fi router. on my iPad mini and iPhone 6 plus.. I pay for 50 Mbps download and 5 Mbps upload... Yet I get over 100 Mbps burst then falls to 55-60 Mbps... Then upload hits burst of 30-35 then falls to 7.5 Mbps.... So it can't hurt to check out how it works for you... My ex pays for 15 Mbps and get bursts of 30 Mbps after I made changes...

http://code.google.com/p/namebench/

I've updated to 2607:f8b0:4004:802::1011

Early yet, but showed an improvement (26mb before change, 34mb after). I'll keep checking

Thanks for the tip

What speeds to do you pay for??? Download and upload... Should help both... Notice quick burst as download and upload speed test starts??.... Then falls to a little higher than you pay for... Text it to your friends... No problem.. Been using it for years...

You can improve home network by checking DNS servers close to you.. Laptop works better also... You can test the DNS # you had and see the average 40-80 or 90 milliseconds.... Both of mine are set with DNS servers that gets an average of 18 milliseconds...

Both give average of 18 milliseconds response time.... So how long do people want to wait before the internet responds to your click?? 18 milliseconds with each click??? Or wait 60- 80 milliseconds for each click??? It adds up as you surf the net.... My old DNS was slow.... Not anymore... I have DNS test in my security camera on my house.... Can test DNS servers on my security system also.... I set my security cameras to use fastest DNS servers I could find and the never fail to load almost instantly on Wi-Fi or LTE.. Laptop... iPhone/iPad/iPod.... 1080p 3rd gen Apple Tv connected Samsung smart tv that has internet also. All work get at the same time......  No issues....
