Q: iOS 9 wifi connectivity problems

I had same problem I just reset everything and it worked for me

You're welcome. 

Spockk, are you running AdBlock on your Safari?  A friend of mine was complaining that his sonos wouldn't work after he downloaded adblock and he saw some of his websites would take super long to load.  Can you check?  Disable it and see if the sites load in Safari, he was able to do that and it worked.  Personally, I have not had problems with adblock but it's a long shot.  Also, which sites are you on?   My usual sites load just fine on Safari or Chrome.

I also am having line of the same issues. I have a brand new 6s Plus, and a iPad Air 2. The phone works fine with my home wifi network (WPA2 encrypted, all standard settings including a broadcasted ssid). The iPad however, does not properly connect to my Home wifi on iOS 9.01. It obviously worked before iOS 9.0 because I downloaded the update via the same wifi connection (I think, unless it was accidentally downloaded via phone tethering at the airport). Nevertheless, this is the problem:

the iPad sees my wifi network, then continues to attempt to connect to it (spinning connection circle to left of network name), but does not connect. I CAN get the iPad to connect to my tethered iPhone. But that is not a long term solution for me since my iPad mostly lives at home and I travel frequently.

I've tried everything mentioned above except restoring a previous OS version (which I don't have). I'm very disappointed with Apple...

I had to install iTunes for Windows on my PC. Then I downloaded the entire 9.02 operating system for 70 minutes. I connected my iPad Mini 2 to my computer with lightening to USB from my charging connection. I installed it by finding my iPad In my computer iTunes app. It wiped out all my iPad settings,, bookmarks, and favorites setting it all to factory settings. I have gone hours without disconnects. It is like it was before the IOS 9 upgrade.

TThank you so VERY much for responding to my plea for help.

UNfortunately, that did not resolve the problem. I do have Adblock installed but that didn't do it.

not all sites stall and don't connect, just some. i frequent sports sites and message boards mainly, like Bigblueinteractive and Fantasy Football today.

THe the weird thing to me is I can go on the site through Google search, but I can't save the site as a favorite and then get back on though the favorites. no one I've talked to can figure it out and I've yet to find someone address this problem on any website.

LEt me know if you come up with some solution. I'm all ears and I check this site daily, just hoping to be back like the way it was in IOS 8.

Hi all,

I am also having a similar situation.

I have an iPad 2 and iPhone 5.

Upgraded to iOS9 and my iPad will not connect to my home network (I get an error that it is unable to join the network). The iPhone and all my other wireless devices work fine though.

In my office I am able to connect with the iPad.

Both my home and office networks are running WPA2.

I tried forgetting the home network. No change.

I tried rebooting the iPad. No change.

I wiped the device to factory defaults and set up as a new iPad (so I obviously did not restore a backup in case there was an issue there). No change.

According to https://support.apple.com/en-za/HT201299 Wi-Fi Assist is not available on the iPad 2, so even though the iPad has a SIM, I presume that is not causing the problem.

Same problems here. 

Brand new iPhone 6s (AT&T version).  9.0.2, Airport Extreme Base Station.  5ghz (although I've tried it on a 2.4ghz network with the same problems). 

Right when I toggle the wifi on, I'll run a speediest with results as high as 50mbps download.  But halfway through, it'll seize up and the numbers will plummet.  Upload will be significantly lower, if the test even finishes.  The next test through will be around 5mbps at best, with lots of pauses.  And that's if it finishes.  Usually by the third test (in less than 90 seconds since I toggled the wifi on) it won't even be able to Ping and I'll have to toggle everything off and on again.

My iPhone 5, running 8.1.2 is getting 50+ mbps download and upload.

I've wiped and reloaded the phone several times.  I've disabled wifi networking.  I've reset network settings.  I've tried to manually change the DNS.  Wifi assist is off.  I've reset the router.  I have no VPN.

The only thing I haven't yet tried is dropping this phone off my 11-story building, but I'm pretty close...

What eventually worked for me was to set my router to WPA, then once my iPad was connected I changed the router back to WPA2 and it is working fine.

I too am having this problem with my iPhone 6 and ipad not connecting to the internet despite having a full signal since updating to IOS9 and now IOS 9.0.2.Nothing has changed and it is so frustrating as it all worked ok before .We keep rebooting to no avail. I was thinking of upgrading to the 6s but  now will probably not.Sort this out please Apple

Ok, I'm pretty much in the same boat as most people here, but I have a few things to add...

I have a brand new 6s and like most the wifi has sucked. Signal is much lower than my 4s (running 8.4.1) that I have right next to it no matter where I am in relation to the router or at different sites. That I see as problem #1. (and yes I have wifi assist off).

The second problem is I will arrive at work and I look for available wifi connections and the phone will show my home network and it actually showed a friends network that I had visited the night before also, both with strong signal strength. Obviously if you try to connect they don't work, but they will reappear in the list after a failure sometimes, no more that twice though. This is problem #2

I also have the problem with the WPA2 enterprise network at work. Most times I can't even see the network. We also have a guest network that is just WPA or WPA2, not enterprise, but could not connect to it either. Both networks would only show up if you pretty much stood underneath one of the repeaters. If you tried to connect you would get "cannot connect" errors or "incorrect password" errors even though the passwords were correct. Problem #3

Now the weird part... we have several HP printers that have wifi access. They typically were the only things that would consistently show up in the available network list, never fail. I never would connect to them because they are located at certain individuals desks they are strictly local printers, not shared on the network, plus I had no need. They also are open networks, no security at all. I accidentally connected on day by tapping the wrong thing one day. IF you connect to one of these printers, suddenly the WPA2 Enterprise and Guest network show up and guess what? I can then connect no problem for most of the day without problem. If you get to a dead zone for wifi in the building it may drop off and you may need to actively reselect the network and it will most times connect right back up. Several people (at least 5-6) at work were having the same problem and if they link to any of the printers that show up, they suddenly see the Enterprise and Guest networks and can connect just fine.

Now every morning I have to connect to the printer and then reconnect to the Enterprise network. Another thing seems to be that if you "Forget" the printer network so that it doesn't hop to it when the enterprise get a little low on signal, it seems that a good bit of the time it will not reconnect unless you rejoin the printer network. Leaving it in there seems to cause less problems.

On a side note, I've also noticed that the Cellular reception is not as good as my 4s either. Not sure where that falls into the puzzle...
