speedtest.net is hard to understand. I tested my iphone and on my macbook and ill get 13.01 on my iphone and 13.50 on download on mac. then ill get like 60 upload and 20 upload on my mac, but then it will vary sometimes on teh phone to 8. but the speed test app will start freezing. so idk is there another app.
This is all explained earlier in the threas, but again:

When you run speedtest, the app randomly picks a server in your area. Some servers are much faster than others. In my area, there are three speedtest servers. One of these servers reliably returns 70+Mbps with 30-40ms pings. Another of these servers reliably returns 30-40Mbps with 100ms pings. The last of these servers returns anywhere from 0.5 to 5Mbps with 200-400ms pings. Thus, my results vary from 0.5Mbps to 70Mbs if I let the Speedtest app choose the server. I only get consistent results when I manually pick a server for each test. If your results are bad, pick another server.

Don't jump to conclusions about your Wifi performance before duplicating your results on multiple servers. Several people who thought their iPhone was defective found that performance was normal when they switched servers.

IMO, virtually all other WiFi issues mentioned in this thread are software and/or driver configuration setting issues on the iPhone5, and most people are returning perfectly fine, non-defective phones. I've beta tested a number of Wifi devices in the past and have observed very similar issues in the past caused by firmware/driver bugs, all of which were fixed by new software. Numerous members on this forum and others have resolved their Wifi issues by changing a setting on a router, rebooting or resetting their router, resetting their iPhone, and/or setting up from scratch without restoring an iPhone 4/4S backup, all of which provides further evidence that this is a software issue

I fully expect that Apple will figure out the common causes soon and fix/prevent the issue in IOS 6.0.1. If your phone is perfect in all other respects, consider giving Apple 2-3 weeks to address the issue.

If it was software would it not affect all iPhone 5s running iOS 6? Some have had luck with exchanging phones. That's the only thing that bothers me. My phone is perfect. Exactly what I wanted except for this wifi issue. I hope we hear from Apple soon about an upcoming iOS update.

A Wifi device is supposed to function consistently across many different Wifi implementations and network configurations, but software/driver bugs can cause packet loss, reduced throughput, or both, on certain networks and/or under certain conditions. Potential software issues probably outnumber potential hardware issues by 100 to 1 with mature Wifi silicon implementations like the Broadcom BCM4334 (Murata 339S0171) in the iPhone5.

My 4s getting around 30 or so ( out of 50) while the 5 not getting what some are experiencing its not getting the full amount it should. But since its not as bad as some that I read waiting for apples word on the matter.

I'm wondering if it is router/network related- for instance I have fios with the actiontec (default ) router they supply
 
Network: WPA security to Time Warner cable with an ATT Microcell. I'm paying for 10Mbps download, 1Mbps upload speeds.

iPhones: one 4, one 5, both on iOS 6. Beside iPhone hardware, everything else is equal.


Speedtest Ping, Download, Upload
iPhone 4: 275ms, 10.15Mbps, 0.74Mbps
iPhone 5: 420ms, 5.13Mbps, 0.80Mbps

After applying wepiii's tip to iPHone 5:

iPhone 5: 25ms, 5.33Mbps, 0.72Mbps
re-ran test

wepiii's tip helped my Ping speeds a lot but not download.

Summary: My iPhone 5 WPA-connected download speed is half that of my iPhone 4.
Also:
Summary: My iPhone 5 WPA-connected download speed is half that of my iPad 2.
Tonight my Speedtest results for iPhone 5 and iPhone 4 and iPad 2 were almost identical.

a self-correcting problem?

or intermittent...
 
Been comparing a iphone4 and iphone5 this morning and the iphone4 is consistantly nearly twice as fast at downloadling. Test over 10 times, upload speeds are nearly identical.
 
Did you call a store, or the customer service number? What did you tell them, and how did they acknowledge/describe the issue?

I want to get mine replaced this week.

Thanks!

I called customer service after I did a ton of troubleshooting on my end. They gave me a case number to put on my appt with the store. He also stated they have a ton extra at the store to replace what I have. Poor guy on the phone got an earful from me about it. I am none to happy about this issue. :mad:

From some of my testing trying to block the antenna was not my issue. It would do it no matter what I did except to remove the security on my wifi network. To get thru to Friday I setup a unsecure wifi and it screams now. So this is clearly a packet loss do to encryption and hardware. Apple is completely aware of it and is fixing them.

I will say this comment, I had a co-worker go oh so maybe you should have gotten a Samsung...(FYI he has an iPhone 4s). What I am getting at don't jump ship, new designs always have flaws and Apple tries to help as much as possible.

My 2 cents!:apple: Rules!

try resetting your wifi router, not as in a full reset, but just unplugging and plugging it back in.
 
So at home my 5 was getting about 10 Mbps on an 18 Mbps wifi connection. All other iOS devices running 6 got about 17.5 Mbps. I went to school this morning and my MacBook Pro was getting around 27 Mbps. My 5 got about 22 Mbps and a classmate's 5 was identical to mine. I don't know what's going on. There's no reason why the 5 shouldn't be performing at the top of the list. Hopefully this is a software issue. Additionally, I have also noticed a drop in reception on AT&T in areas where my 4S was always 4 or 5 bars. It's disconcerting at best.
 
With all the comments going around multiple forums and now news sites too about the wifi issue...

Has it been narrowed down to whether this is hardware or software?
I've had a couple of drop-outs and connected but unable to surf (4S is ok at the same time on iOS6) and also had a nick or two but unsure whether this warrants a replacement if it's just a software issue.

Last thing I want is to be replaced with what seems to be more of a problematic version/week 37 unit for the replacement of my week 35 unit
 
Mine is seriously slow on wifi too. Ok after a reboot or a reset of network settings, but eventually it crawls to a stop. To the point where it wont even ping a local server with speedtest.net. Put it back on 3G and its instant.:(
 
I am having the same issues at home but they go away on my schools wifi.. I guess i should try a clean install first and then try again.

Anybody else in the same boat?
 
For those of you who got a replacement iPhone 5 from an Apple store did this fix your issue?
 
To everyone saying "reboot your router" or "change your router settings", etc...

THAT IS NOT AN ACCEPTABLE SOLUTION.

Why would you need to do that when EVERY OTHER DEVICE is working perfectly fine on that very same connection? iPad, iPhone 4, MacBook Air, HP laptop... all get the same speed, from the same servers, on the same wifi, in the same room... yet iPhone 5 does not. It clearly has nothing to do with the router, the servers, etc. This isn't rocket science.

You do not have access to just reboot every wifi router you connect to. You can't expect everyone else to accomodate and work around a problem with your phone.

Plain and simple: If my iPhone 4 works, my iPhone 5 should work just as well (if not better).

Thanks for the post. I was going to go to the Apple Store after work and explain it, but I think will call customer service instead so there is a record of it first.
 
I noticed some unusually low speeds, the first two days... but I'm not sure if it was my phone. Whatever it was, I guess it resolved itself.

I did the speed test and my iPhone 4S was much faster on my wifi than iPhone 5 is this normal I noticed to when I lock my phone it's says lte not the wifi symbol is this normal??
 
I belive the problem to be iOS6. Both my iPhone 5 and my wifes iPhone 4S are now running cripplingly slow. The laptop is running fine, 10mbps down, 1mbps upstream.

If we reset network settings on the phones, it works (slowly) for a period of time, until it gets slower to a crawl, and then my iPhone 5 will no longer upload via speedtest.net.

Edit: Just set the wireless options on my Time Capsule to: WPA/WPA2 Personal instead of WPA2 Personal. Also forced it to use channel 1 instead of Auto. Network settings reset on both phones, and both seem ok at th moment. Whether they slow down or not, we will find out.

Could be iOS 6. Could be the phones. We won't know exactly until Apple investigates this more.

For me, iPhone 4 still running consistently fine. My iPhone 5 is running consistently fine on par with the iPhone 4. My macbook runs the same.
 
Posted before, but as a reminder to those seeing poor results...

The last of these servers returns anywhere from 0.5 to 5Mbps with 200-400ms pings - clearly that server cannot handle the increased traffic it is seeing this weekend. Thus, my results vary from 0.5Mbps to 70Mbs if I let the Speedtest app choose the server. I only get consistent results when I manually pick a server for each test. If your results are bad, pick another server.

+1 my iphone 5 is normal on all servers except the closest one which is showing 10 down and 2 up. Iphone 4 doesnt show this. Must be a speedtest/ios bug.
