Reports of Slow and Inconsistent Wi-Fi Connections on Some iPhone 5 Devices

I don't think the problems described are affecting my phone, however, it does seem like the wifi on the phone is slightly "deaf" compared to previous phones and our iPads.

Oh, FFS. How many people here were actually *alive* when the actual namesake -gate scandal took place, hmm?? The one that, for the first and only time thus far, forced a sitting president to resign from office? We're, effectively, comparing that level of scandal to "you're holding it wrong." Really?

Nsayergate = Keeps losing humour signal!
 
the replacement has started doing it now :( I need to spend some time playing with network settings to see if I can nail down the cause further.
 
The reason is that you must enter the DNS server info manually for every WiFi you connect to, or the iPhone's connection will be slow or non-existent.

I discovered this by trial and error.

Even though I was 'connected' to my home Wifi, the phone downloaded the data via AT&T instead of my own network, caused me to exceed my monthly data limit in a few days.

My office Wifi did not work either. Same with the attwifi hotspot at my nearby Startucks and the Comcast hotspot 2 blocks from my house.

Turns out that all 4 networks worked perfectly fast only after I manually entered the DNS servers.

System restore and every other attempt to solve the problem did not work.
I need a new unit.
 
For those of you with the iPhone 4S i fixed my wifi issue by resetting network settings and then all was well.
 
My Problem has been Solved

You are not going to believe this....

If you are using SPEEDTEST...

Delete the app.

Re Download the app.

Problem solved....
Report back your findings...
21 down.... 3.5 up....
Fixed for me:eek:
Oh, and if not- change the server to another local

I had the same problem with mine. The tech at RS told me how to fix it. Go to settings/wifi select "other"/ type in your router's SSID-select security type- enter password- Done. Your iPone 5 will now remember your network. It worked for me 3 days ago and no problems since. Hope this works!

This is exactly how I got rid of WIFI problems on my iPad 3.
 
Got my replacement iPhone 5 yesterday, and tested by setting it up as a new phone. Had no issues, and after a few hours I restored from backup and everything still works perfect. If you have an issue, call AppleCare and return the phone. I've got a 32GB, Black/Slate, AT&T version.
 
I have the latest time capsule and its not the router, its the iPhone 5. My speed is less then one MB. I test all possible comments from this forum, no luck. Sometimes is just disconnect from the airport or you just see the signal going up and down. I talk to Apple support and I was in line to talk to a senior support but never went there because the guy just told me that the Senior told him that the iPhone was defective . So already call att and now waiting for a replacement. BTW I tested with the iPhone 4S and doesn't have the same problem.

Updated my Firmware on my Linksys WRT54G Router. My iPhone 5 now flies on the thing. No more WIFI issues here. Thank God.

This also worked for me. I have a Cisco Linksys E3000 router. I upgraded from 1.0.01 firmware to 1.0.04.

I'm running a Netgear N600 (WNDR3700) dual-band router on my home network and I've never had any problems with my iPad 2 running iOS 6.0. And that's on both the 2.4 and 5.0 GHz connections. Of course, it helps that the Wi-Fi antenna on the iPad 2 is a lot bigger....

Methinks it sounds like a iOS bug and that may be addressed in the first "maintenance" release of iOS 6.x very soon.
 
Just as another data point....

The wife's iPad2 was apparently horrible on wifi after updating to iOS6, basically zero connection, occasionally getting enough to pull some emails or iMessages. Tested it with a speedtest app last night and it didn't even really run the down/up test, ping was ~500. Seemed to just freeze. Rebooted and re-setup the network settings, and it came back. ~50 ping, 9-12Mbps down. Dlink 2.4GHz router. We'll see if that lasts, since so many have commented on it changing back to bad.

OTOH, I'm not real happy with the performance of this router. I seldom get wireless numbers like people post here. 9-12 Mbps is not great when my wired computers always pull over 30. N wireless should not be that slow. Sometimes my i4 gets over 20.
 
Go Get the phone replaced.

I had problems with really slow wifi -- pings in the 100's, and less then 1mb/s DL speed on a 50mb/s connection.

I called Apple, took it back to the Apple store for a replacement. The replacement did the same thing. Very slow, not just on one network, but on every one I tried that used WPA2.

I tried a bunch of mumbo jumbo (everything) and nothing worked. I finally took it back a second time for a replacement. They replaced it and gave me a third iPhone. The third one worked. I get the same speed now as my 2012 MBP
 
What is the first two set of numbers in everyone's wifi address? For example we have two phones with 98:FE and both have issues.

I assume that you're referring to the MAC address of your 802.11 NIC.

This should be irrelevant for TCP/IP connections - but it does give a strong link to the build date of your 802.11 chip.

If there's a revision level issue with the hardware, then NICs with similar high order bits of the MAC address would likely have the same problems.

Oh no! And my phone is "preparing for shipment", so I couldn't even cancel it if I tried! And I was SOOOO excited for this phone! But, problems with wi-fi?!?! That could really be a deal killer, since my AT&T cellular signal is 1 bar or less in my office. I need to forward my cell calls while at work to my office landline, and I use wi-fi for iMessaging, FaceTime and other apps at work. But without wi-fi, and limited cellular service....I don't know.

I can't believe this problem slipped past all of the early reviews! It's like antenna-gate all over again!

Wait until you get your phone.. it might be fine. Don't hang crape before the funeral.

Updated my iPod Touch (4th Gen) to iOS 6 and my Wifi has never been better and the response to screen touch is much faster than iOS 5, which had a noticeable lag after screen command.
 
How are people "testing" the speeds of wifi?

It seems, as I reported earlier, that some apps are not accurate. (wifi disconnections on the other hand are different).

I use Speedtest.net app.

If I use a local server, I get 6 MB down, and 2.75 up.
If I change that server in the app to another state nearby, I get 21 MB down, and 3.5 up.

It seems (and I am only speculating), that the actual application you all are using may be a part of this puzzle.
This btw, is going without changing any DNS settings, or proxy settings or the like within the wifi settings on IP5.

So, I recommend that those who are indeed dealing with slower speeds on wifi, check out another application in the app store and do some comparisons. However, I do not know why one server nearby shows good speeds on the 4S yet poor speeds on my 5.
