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

This sucks

Hi.

When I connect to my G network I have fast speeds all over the house.

When I connect to my N network the speed drops down to almost nothing.

Shouldn't the N be the fastest?

Something is clearly wrong.

My setting are exactly the same for both home networks. They are just running on separate antennas.

Had the same issue with my iPhone 5 yesterday. Worked all fine in the beginning and suddenly I wasn't able to send any iMessages, download apps etc. anymore.

Trying the Speedtest.net app I got the same "searching for closest server" on a loop, while on 3G everything was just fine. WiFi on my Mac was also 30mbits as usual.

First I thought it was a proximity issue and that the aluminium was hampering the speed.

Then I took the common advice that every IT employee would give you: "Have you restarted your device?" and oh look, after the reboot wifi was back at 29 mbits...
 
are these pics just to make me look bad ?, or do you guys prefer to use LTE/3G allot ?

:eek:
 
Not a problem for me

Ran Speedtest three times - 1st on AT&T HSPA+, 2nd on LTE, 3rd on WiFi through Comcast xfinity (20 Mb). WiFi via WPA2 is a little slower than on my iPad 2, and half as fast as my MacBook Air.

Almost thought I had this issue too. Then checked it on my MBA and it just turns out my ISP is just being a cheap SOB with me....time to complain :rolleyes:

As of note: This Wifi issue is no such problem to those who are grandfathered in on the Unlimited data from their mobile carrier. Unless you live in a low signal area. In which case.......flood the support forums so a fix comes faster haha
 
Soon after connecting with my iPhone 5, I experienced slow speeds and speedtest app was stuck on "finding closest server" on my dual-band AirPort Extreme (connected in 5ghz mode). After a restart of my Airport, I'm getting consistent 30 mb down/5 up. Equipment may have just needed a restart, but other devices on WLAN were working fine. Weird.
 
Found this thread after searching on a problem I seemed to have - had no idea others had it too.

- iPhone 5, wifi speed was originally as fast as I expected from my home network. Felt very speedy in fact.

- While travelling this weekend, had trouble with the hotel & train wifi networks, kept disconnecting and slowing to a complete standstill. I just thought they were poor networks. (These networks were unprotected though, no WPA or WEP btw)

- But after I got back, home network was slow/not working too - I had to turn it off and use 3g.

- Rebooted the phone this morning and it's working/back to full speed.

Feels like software to me, maybe related to band switching? If hardware could be an aerial issue triggered by software?

Hopefully this problem is not based in the hardware. Seeing as the reports indicate that it may be a WEP2-specific problem, it seems to be software-related and can hopefully be fixed by an update from Apple.

I'm sure it's just a software issue (albiet a weird one), and will be fixed promptly. But honestly, this is not surprising at all. Having followed Apple for a long time now, Rev. A products/software is always a little buggy. Luckily, it usually gets fixed fairly quickly. While this is annoying for sure, it's only very temporary.

Not necessarily. According to wikipedia

To achieve maximum output, a pure 802.11n 5 GHz network is recommended. The 5 GHz band has substantial capacity due to many non-overlapping radio channels and less radio interference as compared to the 2.4 GHz band.[7] An 802.11n-only network may be impractical for many users because they need to support legacy equipment that still is 802.11b/g only. Consequently, it may be more practical in the short term to operate a mixed 802.11b/g/n network until 802.11n hardware becomes more prevalent. In a mixed-mode system, an optimal solution would be to use a dual-radio access point and place the 802.11b/g traffic on the 2.4 GHz radio and the 802.11n traffic on the 5 GHz radio.[8] This setup assumes that all the 802.11n clients are 5 GHz capable, which isn't a requirement of the standard. A technique called "band steering" is used by some enterprise-grade APs to send 802.11n clients to the 5 GHz band, leaving the 2.4 GHz band for legacy clients. Band steering works by responding only to 5 GHz association requests and not the 2.4 GHz requests from dual-band clients.[9]
[edit]40 MHz in 2.4 GHz
The 2.4 GHz ISM band is fairly congested. With 802.11n, there is the option to double the bandwidth per channel to 40 MHz which results in slightly more than double the data rate. However, when in 2.4 GHz, enabling this option takes up to 82%[10] of the unlicensed band, which in many areas may prove to be infeasible.
The specification calls for requiring one primary 20 MHz channel as well as a secondary adjacent channel spaced ±20 MHz away. The primary channel is used for communications with clients incapable of 40 MHz mode. When in 40 MHz mode, the center frequency is actually the mean of the primary and secondary channels.

What I understand is that for optimum performance the router should be configured for 801.11N @5GHz only. If used @2.4GHz you may get a lot of noise from nearby WiFi using same frequency. As I don't have a 801.11N network I would guess that also changing the channel (if there is such an option) would improve the situation. Finally if your router was made before October 2009 where the protocol was finalised, it may have not properly implemented it.

If I am wrong please feel free to correct me.
 
Hmmm.

Here's what I can see.

I have my N network broadcasting at 5 and my G network broadcasting at 2.4.

I have some older devices in the house that are G only and several newer devices that are N capable.

That's why I'm running both at the same time.

Am I doing something wrong?

My experience with the iPhone 5 on my home network has shown me that I'm fine when connected to 2.4ghz but on the 5ghz side of things sometimes it doesn't show a connection or it'll drop the connection while my desktop which is connected to 5ghz remains connected, strong and steady.

No slowing, just unavailable at times. The times I am connected the signal as just as strong as the other devices on my network.

Hope this helps.

Same here. We have 5 iPhone 5's in the family an the issue seems to be staying connected to the 5Ghz band. When connect it shows weak signal, is slow and disconnects quite easily. Don't notice as much issues on a 2.4GHz band and the connection seems more solid and doesn't drop.

Not at all. Although "mixed mode" will only be as slow as the slowest device.. (2.4 Gig.)

This and the tiresome "Steve would never allow", which crops up every couple of pages are the sign of a mind devoid of any original thought.

I'm just waiting for this, regarding this from Apple with the iPhone 5 as a possible cause for slow Wi-Fi /dropped connections symptom..

They did with the 4s regarding cellular.

Your phone was connected to different servers at San Jose, Palo Alto, San Francisco. Same server has to be used to compare apple to apple.
 
Before I got to work I ran a few speed tests...

My Ipad is always up to about 30mb/s, although I am on Fibre Optic with at least 80mb/s, but not sure because its a wireless device.

My Iphone 5 was pretty slow last night, but this morning I had nearly 20mb/s and upload between 14-18mb/s.

My PC which is connected with a wire (yes, they still exist ;)) is on a constant 60mb/s the least....
 
Had same issue with iPhone 4

I had the same issue with my iPhone 4 when it first came out - I would get intermittent connectivity for a few minutes and then nothing on my home wi-fi. Everywhere else it worked fine. I got several layers deep to Apple's technical support but never got close to resolving the issue.

Eventually I upgraded my home wi-fi router and the problem disappeared. My guess is they changed chipset in the iPhone 5 and this has compatibility issues with a number of wi-fi routers already in circulation out there.
