Q: iOS 8 Wi-Fi problems

You'll find that if you do an over-the-air packet trace, that the phone itself is not listening to the network for periods of up to 400 milliseconds.  Then all the packets come in a big burst, followed by another 400 millisecond silent period.  It's quite strange, and I've been unable to find anything to 'turn off' or reset to make this problem go away.

I have, however, seen a device not have this problem.  Powering off and on the phone makes the problem come back, however.

I've the same problem after upgrading to IOS 8 but I noticed that it doesn't work at home but it works at work so I would recommend every one to post the type of router they have that IOS 8 doesn't work with and the routers that their phones have no problem with just in case any one wants to buy a new router

Home Router (Doesn't work): Tedata (Local Egyptian communication company)

Work Router (Works perfectly) : Etisalat (same as above)

My router is an Asus RT AC 68U. If I connect up my airport extreme from apple and connect IOS 8 devices to it all is well.

Apple Extreme Router A1354, two iPads on 8.1, both now in the draw as they aren't useable.

IM glad this has worked for you. I still wonder what it has to do with oout out router Whigs we have had for at least 6 months working just fine. Io8 is the only new thing in the equation.

iif something sstops working it is usualy the new item that's to blame.

Is that your iPad causing the double letters, mines doing that as well, excellent new feature of 8.1!!

yes when when it actually lets me write on the forums my iPhone and tablet both keep doing the double letter trick.

tkdsouth were you one of the people that Apple provided the logging config to for debugging?  I was just asked to do this as well. Did you ever provide the logs?

Silly question... Has anyone else had wifi issues with ANGRY BIRDS open? ...

This took me a week to figure out on my iPhone running IOS 8. Wifi was running erratic or not at all on my phone for no reason. Have 20mps on my laptop with FIOS. Had to remove everything 3 times off my phone and started loading things on one by one. ANGRY BIRDS STAR WARS was the problem. Don't ask me why but try closing & see if this helps! Good luck!

When I first read your idea about Angry Birds, it sounded crazy... then I tried it, and I'll be damned. In my case, it's Angry Birds Seasons. I can run a speedtest, and it is fast. Then I open and play angry birds seasons for a minute or two, and re-run the speedtest. My results drop from 50 mb/sec to 6 mb/sec. Amazing. Close the app, and it's relatively normal again. ***.

Yesand yes. It was only a 24-hour testing

I discovered the same thing a couple hours ago on both the Iphone 6 and Ipad air 2...

I discovered another way to re-activate my Wifi speeds -- I found that when I'm doing other activity on my Ipad such as by playing Angry Birds Rio HD for five minutes or so then I go back to Safari to perform a speed test then I create the wifi slowdown from 25Mbps to about 1-2mbps or so -- I tried everything to bring it back and the only thing that worked was a hard reset -- now that I had somewhat a consistent way of creating the problem I played angry birds Rio HD again but this time I removed all apps that were playing the background including angry birds, safari etc -- this time when I went back to my speed tests the speeds were normal again --- I created the problem and brought the speeds back to normal following removing all active apps in the background 3 times --- Hmmm I wonder if there's a memory leak between wifi and the apps ---

Wondering if others could bring back their speeds after removing all active apps in the background?

Yes, if I close my apps down (angry birds specifically) and run a speedtest, it starts slow - but gets faster. If I toggle airplane mode on and off, then run another test, it's back to full speed it seems. I'm a developer, and I concur with your idea - this seems like an epic memory leak of some kind. Odd, because I thought applications were sandboxed and unable to cause this kind of an issue.

I wonder if it's related to Game Center?

I'm not a developer... just a guy with a phone!

Glad I could help!

Cheers!
