My 5ghz WiFi does not work anymore on iOS 7

I have an iPhone4 with IOS7. I am sitting near my Airport Extreme which offers both 5ghz and 2.4ghz and it is connected to the 2.4ghz network. If I forget my netwrok connection and search for a new network it does not see the 5ghz network only the 2.4 ghz network. It connects ok to the 2.4ghz network. 2.4ghz is fast enough for the iPhone. Speedtest indicates it gets the maximum speed up and down through my internet provider (30 and 10Mbps). My iMac can connect to either 2.4 or 5ghz.

d-oh, 5ghz is not available on iPhone 4.

My D-Link DIR-825 is a dual band router where I can set two different SSIDs for each band and I have my 4th gen iPad only join the 5gHz band. My iPhone 5 will join the 2.4gHz band unless I sellect the SSID that is running the 5gHz band.

If I read your comment correctly, your iPad used to join your network with the 5gHz band and now your iPad can no longer join your network on the 5gHz band? Can another device join the 5gHz band?

As for the speed difference, you shouldn't notice any difference with internet speeds unless you are one of the lucky ones that has better than 54 Mbts to your network, but you will notice a difference if you are streaming locally over a gigabit network. I can see a huge difference in speed when printing a document over the slower band verces the faster band.

I have a ipad 3 and can not connected to my 5ghz network after update to ios 7.

My iphone 5 can join both band

As I stated, my iPhone 5 will join the 2.4gHz band first automaticlly, but if I want it to join the 5gHz band I will have to select the SSID that I have for my router's 5gHz band, because I have a SSID for the 2.4gHz band and another SSID for the 5gHz band. The iPhone can not join both bands at the same time, it will switch between the two bands based on signal strength.

Just to be clear, a device will join a dual band router on the band that has the stronger signal, which is usually the 2.4gHz band. If you can seperate the bands with different SSIDs, then you can choose which one to join, but 2.4gHz has a longer range so your device will choose to join that band first.

Ditto. I also list the ability to connect to 5Ghz wifi, either automatically or manually, on my iphone 4s. However, I am able to do so with my iPas2.

My iPhone 4S was connected to my 5 GHz band on iOS 6, but could see the 2.4 GHz band.

Now, it can *only* see the 2.4 GHz band *right* after I updated to iOS 7!

I have them named seperate things, so I know the 5 GHz band is no longer seen.

Restarting the phone did nothing either.

It's def broke. Fix necessary

Your iPhone 4s can not connect to the 5gHz band, you can see the iPhone 4s technical specifications here; http://support.apple.com/kb/SP643

Apple has clearly changed the behavior of the iPad 3 (at least) with regard to wi-fi networks which use a single SSID for 2.4GHz and 5GHz signals. The iOS 6.x behavior chose the 5GHz band first if usable, then fell back to 2.4GHz instead of using raw signal strength as the deciding factor. I now have significantly more iOS-based traffic on my 2.4GHz bands in my production network thanks to this change.

Apple, if you're listening, it'd be great if you reverted to the more intelligent algorithm; 5GHz will often appear weaker to endpoints but provide a vastly better experience in dense environments.

Bump. Any progress on this, Apple?

Same here with iPad Air and TrendNet 5ghz N connection (WPA2), will not join the network. Have to use 2.4ghz N. My Macbook Air however after Mavericks update does not have any problem with 2.4 or 5ghz to same router.

Hi Bob,

Have you tried turning off the 2.4GHz band on that router to see if the iPad will connect to the 5GHz band? Just currious.

On a side note, the TrendNet site has a bunch of firmware updates this month, could the your router's firmware be out of date?

Just some thoughts.

Cheers,

UG,

Thanks for challenging me to dig deeper! .... I tried your test and also tried turning security OFF and that did not work. Firmware was current.

BUT .....

While I was in there I noticed that I had MAC address filtering enabled ... forgot about that, and I was using my new iPad Air (had traded in my 3rd gen with Best Buy as part of their launch incentive).

So ... nothing wrong on my end ... my bad. 😢

Hello Bob,

If I understand your post, your iPad still could not join the network.

A few thoughts.

Was your iPad able to see the 5GHz SSID? If your Mac can see the 5GHz SSID and your iPad could not, the iPad might have a radio problem. Just to be clear, the 5GHz band SSID is set to be visible?

We know it isn't a problem with a password, or encryption.

I'm sure you restarted the iPad at some point, if not give that a try. Holding the Sleep/Awake and Home button at the same time until the Apple logo appears, then let go of the buttons.

Apple will suggest you use Settings>General>Reset>Reset Network Settings, I personally haven't seen this fix many of the problems I've come up against. Don't rule it out, it is worth a shot.

If you don't already know, Apple will focus on your router as the source of the problem. With my launch day 1st gen iPad, it had problems with Cisco routers using Mixed protocols, but had no problems with an old AirPort Extreme using Mixed protocols (the iPad had a good connection, but couldn't communicate the network after coming out of sleep).

Your iPad is still under Apple Care, you should set up an appointment with the Genius Bar if you can, they will test the iPad and read its log files to find the problem.

Good luck,

UG
