I've been having problems with wifi stalling on my iPad Air since beta 2 where I either have to turn the wifi off and on or forget the network and reconnect. I haven't installed the GM on my iPad yet, but I'll report back when I do.
Both my personal iPad Air and a friend's iPad Air with cellular are having problems getting anything from 5 GHz bands. Sometimes you can connect and it'll work for a couple minutes and then quit and sometimes it doesn't work right off the bat. Meanwhile the 2.4 GHz band on the same routers work fine.
I was excited for iOS 8 because my iPad had this thing where it would lose connection and i'd have to turn wifi on and off to get it back but this is way worse. Going to be a bad day Wednesday for people who have to rely on 5 GHz to get a good signal in congestion or don't know what the problem is at all.
I have had serious issues (major slowdowns and drops) with both 2.4Ghz and 5Ghz on my 5S. Have the latest developer beta. I've yet to find any reliable fix; resetting network settings does nothing to aid the situation.
Why does Apple have such an issue with Wi-Fi? New hardware & new software is always plagued with Wi-Fi issues. Why can't Apple capture these problems in testing and resolve them before releasing the software?!
I'm having major issues with my 5S and wifi also after upgrading to iOS8. Sometimes I can't load webpages, apps saying cannot obtain connection such as Mint, and some apps just not refreshing the pages such as Instagram.
This only started with iOS8 and happening with both 2.4 and 5 GHz. If things get stuck, I can turn wifi off and back on and things work again but happens every 20-30 minutes to me. No other devices affected. Very annoying
My iPhone 5 and iPad Air, both running iOS 8, have both been absolutely rock-solid with 5Ghz wireless since their upgrade.
I'd even say Wifi performance is better - I'm getting much less drops of signal as I move around my garden, for example, than I used to, it now doesn't drop at all (garden is about 40 yards long) whereas before if I walked to the top, I'd lose Wifi.
Note though I am using a combination of Apple Airport Extreme and Airport Express, if that has anything to do with it!
I have exactly the same issue,
and it's only since yesterday in fact since i have my iphone 6
it happened 2 times in less then 5 hours
i'm losing the wifi and if i want to see the access point i can't see any of them
on my phone 6 i need to reboot to be able of seeing them and reconnect .
Me too. If I spend some time away from the house when I come back I have to power down and back up before it see the wifi - even when the damn phone is just 6 feet from the wifi router. It's an iPhone 6 Plus 16Gb.
I also saw the same issue when I updated my iPad mini retina to iOS 8 GM last week. Was connected to my 5ghz band but no traffic was going through. Switching back to 2.4 ghz worked fine. I'm using a Netgear Nighthawk.
Just got the iPhone 6 and the same thing is happening. My iPad was working fine with iOS 7. Definitely seems to be an OS issue with 5ghz band.
