WiFi keep dropping after iOS 5 upgrade

If this problem has someting to do with interference ( with other wifi or DEC) why did this occure only after the upgrade to iOS 5?

Since upgrading to iOS5 I experience loss of wifi signal. I can hardly use wifi at all anymore on my 3GS. Using iOS 4.X it got the wifi signals of surrounding appartments as well. Right now I can hardly use myh own wifi before my iphone drops the signal.

PLEASE APPLE SOLVE THIS

Hi. Exactly the same. I took my ipad to Apple and it worked fine on their wifi. I reset my netgear N router to factory setting and installed as if new. Iphone and ipad still losing the connection if they are not ten inches or less away from the router. I think it is a router problem

I have been reading this post and many others since upgrading 1 iPhone in the household to IOS5. I have had AT&T out and paid for service. I have had a network guy out and paid for service. They always leave and the next morning, I have no connection to anything WiFi in the house. Then, magically sometime during the day, WiFi starts working again.

This morning, nothing WiFi was up. Rebooted Router, Modem and Wireless-N Access point. Stil nothing for Wireless was working. Then I read a post about upgrading to IOS5, have all the same issues, and then turning LOCATION SERVICES on the IOS5 device OFF. Within a Nano second of turning Location Services OFF, shutting the IOS5 device down.....my WiFi was up and running all over the house. PC's, Macs, and all the iPhones running IOS4 up and running.

Then, I turned the iPhone back on running IOS5 and connected to WiFi instantaniously. In addition, I turned Location Services back ON and still everything is up.

While this is certainly no fix, I'm hoping that by posting this someone at Apple may realize there is a problem and maybe it's isolated around IOS5 and Location Services and GPS. As I said, I have had this problem for weeks, tried everything everyone has posted here and on other places and still, nothing was ever a permanent fix.

I will repost tomorrow to update how my network behaves in the morning. My guess is that the WiFi will be down again and all attempts to reset devices will fail. I will then turn off Location Services on my iPhone (running IOS5), shut it down and check on the WiFi connectivity throughout the rest of the house. As I said, it's not a fix, but hopefully it's now isolated to something Apple can fix and address.

I have wifi connection problems too, on my iMac and Macbook Air right after upgrading to OS Lion, and on my wifes iPhone 4 after upgrading to iOS 5.0.1

For the iOS5 issues with my wifes iPhone 4, I still have not found any solution that does not involve jailbreaking. She was not able to connect to het work network or any other public wifi network. Wifi is not greyed out, but simply keeps searching for networks.

After instaling a brand new Airport Extreme router, all my devices are conncting fine, except for the iPhone 4 (with the update iOS5). From a very short distance (1 meter) I can connect, but further away connection is lost. I start to think that it is a hardware problem that occured simultaniously with the iOS upgrade ...

I gave up on AT&T, DSL and all my Linksys hardware. I have Cable installed, new Motorola modem, Apple Airport Extreme and everything is working like a charm, and 5 times faster than DSL! Plus, I saved $54 a month!

Can,

Thanks for that tip. So far, knock wood, it seems to be working for me.

Hi Lorin,

Am I overlooking something? What tip from Can worked for you. I'm dying to know.

It was the DNS thing, but it actually didn't work.

I have had months now with no issues, but the last two days it started dropping out again. I noticed it on the ipad and iphone, so was dealing with it by turning wi fi off and then back on. As it continued to happen, I again turned off wi fi, then I went to the modem and re-booted it. Turned wi fi back on at the devices and have now had a full day with no issue.

I was having the exact same problem with my FIOS, so I tried rebooting the router. That didn't work on both my iPad 1 and 2. My iPhone 3GS and 4S work fine, however. All of the devices are on iOS 5.0.1. That led me to start delving into the advanced wireless settings of the router where I found the WMM settings. In there, you'll find the WMM power save mode. Turn this OFF. As soon as the setting change applied, all devices are up and running without issue.

The theory behind modifying this option is that the wireless power save drops (or rather chooses not to send) some of the beacon packets in order to save power. If I remember correctly, those beacons are sent every couple of hundred milliseconds. Working with wireless devices since the invent of 802.11b, I remember this was a prevalent issue in some of the older Lucent access points and wireless cards. Killing the power save mode keeps the constant flow of administrative data packets so the devices don't drop out of sync.

Btw, interference/deflection from water (rain outside), metal objects (positioning of metal studs in walls, aluminum blinds, etc), microwave ovens, Bluetooth and neighboring access points can also exacerbate whatever other issues you're experiencing, so that could partially explain why some people run across this issue randomly where they hadn't in the past.

This is ridiculous. This thread has over 14.5k views at the moment and there is no official answer. It seems like many people are having this problem. Where is Apple / a moderator? My iPad is useless since I upgraded to iOS 5. I tried everything that was suggested and nothing has worked. Not pleased with Apple right now. Especially because it was working perfect before I upgraded to the new iOS, should have just kept the old iOS.

edit: Also, not only are there over 14,500 views on this thread alone, there are dozens of other forum sites that have the same question with many views on them aswell...

Apple never gives their official answers here. In all the years I've been on the forums I have not once seen that happen. Look for software updates when they become available, or other official comments on Apple's support site.

Moderators are here to keep the forums up and running and clean of violations of the Terms of Use. They won't answer you either.

If stuff is not working, call Apple and let them try to assist you. Or carry your iPad in to an Apple store. You'll get good service there.

this forum should have Apple's attention.

if it's mandate is to be helpful only for small concerns that can be easily fixed by other users, there is a real need for a beter approach that will get Apple's attention.

Apple should realize there are a lot of knowledgeable users who would like to help Apple make an even better product, by providing feedback to the product deficiencies.

The Apple support site doesn't respond as it should and there doesn't seem to be any other medium for problem resolution ... except to move to an android solution.
