Randomized Wi-Fi addresses

When you’re out running errands with your phone in your pocket, Wi-Fi hotspots have the ability to track your movements and behavior by scanning your Wi-Fi MAC address. A MAC address is a string of characters that uniquely identifies your device on a network. With iOS 8, we’ve introduced an innovative feature designed to protect your privacy by randomizing your device’s MAC address when the device is passively scanning for Wi-Fi networks. Because your MAC address now changes when you’re not connected to a network, it can’t be used to persistently track you. This is in line with Apple’s industry-leading effort to do away with persistent identifiers, and is unique to iOS devices.

Here is an excerpt from another article on MAC address randomization:

"So Apple faced a challenge: their users’ devices were being logged without their knowledge and without their consent. Apple’s adherence to standard network practices — broadcasting MAC addresses to WiFi hubs — created an environment where this situation could occur, leading Apple to make a change.

Starting in iOS 8, iPhones, iPads, and iPod Touches will broadcast random MAC addresses. In Apple’s words, “The MAC address for Wi-Fi scans may not always be the device’s (universal) address.” Companies that log MAC addresses won’t be able to connect individual visits to a single device. They’ll know someone is there, but not where else they’ve gone."

Just do a search on the subject and you will find many discussions on the subject.  Apple is very proud of the capability.

which also adds to why they have made no comment yet.

I'm not having any WiFi issues at all.  I own 3 iPads (3rd gen, 4th gen and 5th gen).  All upgraded to IOS 8.  So here's my question.  How many of you are using an Apple Airport router?  I've attached an image of my speed test from my iPad Air.

Hi guys, i've been experiencing the same wifi problem with my iphone 5s since upgrading to ios 8, and now my iphone 6 is the same.

Been trying all the solutions here (reset network, restore phone, set up as new, turning off wifi networking, etc), but the problem keeps getting back in no time.

Here is what i've been doing, and it seems to work fine with all my iDevices using iOS 8:

- Whenever you are using WiFi, turn off your "mobile/celluar data", and make sure your "bluetooth" is also off.

- Or you can simply turn "Airplane Mode", then turn your WiFi back on. (but this option will make you cannot receive phone calls/sms)

That solution has been working for me for 3 days, just remember to turn your mobile/celullar data back if you dont have WiFi connection anymore.

It looks like WiFi Connection cannot be working with Celullar Data at the same time. Is it related to apple's so called "seamless Wi-Fi Calling"?

Let's hope apple fix this soon!

Are you using WEP security ? Have read some posts / forums that moving to WPA2 security helps and is a confirmed solution

Wish I see the same.. which wireless router are you using?

Looks like some of you have the cellular iPads. Alsha 7 made the comment about turning off your "mobile/cellular data".  Great workaround.  My guess would be there is a bug in the code where the WiFi connection and mobile data aren't flopping back and forth and not staying persistent. All my iPads are WiFi only and I don't own an iPhone.  That is probably why I'm not seeing the issue.

Yes mine is att but i don't have a sim card installed. The ipad also starts that issue and shows "no sim card installed" pop up when it happens. so that make since

Interesting that there seem to be a variety of 'solutions'. I've just retested mine: if I set the 5GHz link to back auto channel it sets to channel 48 and the problem returns; if I set it to fixed channel 46 it's OK. It's all OK at 2.4GHz channel 1 (auto).... but we all have different routers etc.

Yup, i think the problem is with Celullar and wi-fi connection if they're both ON.

My wi-fi only iPad dont have this issue as well.

Actually, I'm using a Verizon ActionTec router.  I'm leaning towards this being an issue with WiFi and Cellular on the same iDevice. 

I've had the problem on WiFi only iPad Air.

From a purely security standpoint, I would recommend WPA2, but the encryption algorithm for WPA2 carries more overhead than WEP.

That is interesting.  Is this happening at all locations (i.e. WiFi hot spots)?  If you are using the Airport Express or Extreme, I wouldn't use 5GHz unless you're in close proximity of your unit.  5GHz has less interference but doesn't have the range that 2.4GHz has.  One of these days, I'm going to invest in a 802.11AC router which I think the newer Extreme's provide.  Are you on the latest firmware release of your Airport?
