Lost my 5Ghz WiFi signals after iOS 11 update

I have the same problem with my IPhone7 too. It detects the 5GHz network but fails to connect saying "Incorrect password"! My password was not changed and I have other devices connecting correctly with the same password. So, the problem is specific to IPhone7 after iOS upgrade. Did your problem get resolved? Trying to find out if you any one in the Apple community or Apple support has a solution. Thanks!

hi sterling,

i have exactly the same problem as redmarlboroman, i have done all the step.

once my iphone 7 plus finish restore ios 11.02, i can see the 5 ghz wifi, no problem until this step.

but after restoring my backup data, i can't see the 5 ghz wifi again.

please help.

thanks.

The steps in your response does not work. I’ve had my cable provider out to my home because I was so confident that an update wouldn’t have my phone messed up. I cannot connect to any 5ghz WiFi connections. An update needs to be pushed out for those users effected. I have factory reset my phone three times and nothing has worked. iOS 11 is a horrible update.

Hello all I am having and been having the same issue, My wife and I have the same phone iPhone 6s although I can see my 5g when I attempt to connect it states the password is incorrect but yet with my wife’s phone the same phone I can connect. The steps above do not work. Please help!

Same problem.

Using: iPhone 7, iPhone 7S, iPad Pro 9.7, iPad Mini, iPhone 5S. All devices can see 2.4GHz and 5GHz except the iPad Pro 9.7. Using Netgear R6250 and EXT6100 and everything was fine before the iPad Pro was updated to iOS 11.x

Thanks for kman2017. I also have same issue on iPad mini after updating IOS. Can’t find 5G WiFi signal and just can connect 2.4g WiFi signal. After modifying DNS setting from auto to manual in 2.4G WiFi setting. Turning off/on once, my iPad mini can find 5G signal

This is a clusterphuck of a release. Root passwordless auth, patch, then patch with accidental removal. Dec 2 bug.

Thought after 2 months the redicilous things woudl settle. But this 5ghz problem is still there.

P.S: Even this form is buggy. You cannot write anything here, it starts to scorll to top of the page. Typed this in an extra text editor.

It also helped, for now. All I did that removed the 5 GHz WiFi from showing up in the list over available/visible WiFi networks was to reset the router. Then it stopped showing up on my iPhone 7 iOS 11.1.2 but my girlfriend’s iPhone 7 iOS 11.0.2 was perfectly working still though.

Weird. Nothing changed. Same settings, name, password etc. Just a reset (because I forgot the login to the router). I didn’t do a single change on my phone.

iPhone 6 have some problem, cannot connect

5ghz Wi-Fi, after reset all network setting. Restore from iTunes, reset everything. Still same cannot connect, I already reset my router. After update to IOS 11.2.5 Wi-Fi 5ghz have problem ady, before update to iOS 11.2.5 there don’t have any problem.

I am not sure if you found an answer. Here is what finally worked for me. When I changed the channel width to 20Mhz. Any other channel width had a combination of either the incorrect password or unable to join error message.

the difference is just the device

redmarlboroman use ipad

and i use iphone 7 plus

i really frustrated after all the step (6 hours process) and stil can't see the 5 Ghz wifi

I have same problem. Cant see 5ghz signal on linksys router.

whats the solution. My iPhone 7 works perfectly.

Hi, I have the same problem with ios 11. My Iphone 7 plus can connect my airport timecapsule network via 2.4 Ghz; however, for 5Ghz wrong password appears! I did no change except for IOS updating.

I have the same problem with iPhone X, iPhone 7 Plus, and my MacBook Air. I can see the 5G network with a friend's Android and a Dell laptop
