iPhone Tips: How to Fix Wifi Grayed-out Problem

by Simon Ng on February 24, 2009



wifi-gray-out-problemAs you may know, I’m just back from Beijing. During my trip, I used to switch on airplane mode to avoid any roaming charge. But sometimes, when I was in a cafe with free Wifi, I turned the Wifi on again. Everything works really fine until I was back home. When I tried to connect my iPhone to my home wireless network, it didn’t work. As I checked out the Wifi option in “Settings” screen, the Wifi option is just grayed out or disable by iPhone itself. Even I rebooted the iPhone, the wifi option still stayed in disable state.

This is not the first time I heard from my readers or other jailbreak iPhone users about this Wifi problem. But this is the very first time I experienced it on my iPhone.

And here is the fix:

Reset the Network Setting

Yes, by just resetting iPhone’s network setting, the Wifi option comes back to normal. To reset the network settings, go to “Settings” -> General -> Reset -> Reset Network Settings.

iPhone - Reset Network Settings

I’m not quite sure if this is the universal solution to the Wifi Grayed-out issue. But this one works for my case. Leave me comment and let me know this works for you or not.

I got this same problem when I upgraded my Ziphone 1.1.4 iPhone to 2.2 using QuickPwn. The Wifi got grayed out but I was able to restore it back by restarting my phone a couple of times. I guess this solution you posted is better though! Thanks for sharing! :)

Guys – If you are not able to solve your wi-fi with the steps above then you may have a more challenging problem. I upgraded to 2.2 from 1.1.2 and my wi-fi just wouldn’t work and it wasnt easy getting to the right solution so i’ll try and make it easy for you. Follow the steps below only if you wi-fi worked before upgrading to 2.x firmware and the above solutions has not helped:

1. Downgrade your phone back to 1.1.4 – http://iclarified.com/entry/index.php?enid=1536
2. Unlock and Jailbreak your phone with iLiberty – http://www.iclarified.com/entry/comments.php?enid=849
3. Finally swifi your phone – http://wikee.iphwn.org/sgold_bootrom:fixwifi

All the software required can be found within the links if you still need any help just reply to this thread and leave your email i’ll do my best…hope this helps…

Solution, Fixed for Wifi Greyed out after jailbreak (Iphone 2G)

If your wifi connection problem is not due to AP settings (i.e. icon greyed out), I have tried various methods and found this to be the working solution to my case. I have used all jailbreak programs (quickpwn, winpwn, ziphone and others) and found the solution fix for Wifi. Would like to share so that the rest can spend their quality time on something more productive rather than going through what i have been through.

Despite the facts of some saying downgrade and upgrade of firmware, or using different version of itune to solve the wifi greyed out, it does not matter in this process.

I am on the following env when wifi is greyed out: Vista, Itune 8.0.2.2, Firmware 2.2.1 jailbreak. tried also on a corrupted restored and it works in both cases.

Solution to the problem:
- Use Itune to shift restore your firmware back to 2.0.2
- Use winpwn to create custom firmware on 2.0.2 (if you are on ATT sim), do not need to select unlock
- Shift restore iphone using the custom firmware created by winpwn

note: if you PC does not recognize iphone, first when iphone is detected as an unknown device, delete root hub one by one and vista will redetect one of them as mobile apple device. To do restore, switch off your phone, unplug USB cable, plug it in again while holding the home button for 20secs, vista will detect it as mobile device.

Another note, after winpwn 2.5 finish created the custom firmware, and after it has put you iphone into DFU mode, Itune will start and winpwn 2.5 will hang, it is completely ok, continue to restore via itune and ignore the winpwn hang. After restore, restart your PC, everything will work just fine.

I was updating my friend’s iPhone from 1.1.4 to 2.2.1 using pwanage tool and got this problem. Everything works fine with my iPhone.
I wanna know if there’s a way i can fix the problem for the version 2.2.1 itself and don’t have to downgrade it to 1.1.4 or downgrading is the only option i’m left with.

Please help.

Okay, now here’s a funny thing… I’d updated to 2.2.1 and got the wifi problem. And was absolutely glad to have found a solution after loads of hard work surfing and searching… But as it turns out i’m now unable to discover the way to downgrading from 2.2.1 to 1.4. The ziPhone thing isn’t able to downgrade my baseband. :(

Regular 3G with 3.0. WiFi is grayed out. Happed a little while after I upgraded. Ran through the Erase / Restore / Sync cycle a couple of times but nothing. WiFi Address registers as N/A. Will be walking this to an Apple Store tomorrow, but I am out of warranty. Screwed?

Outstanding! Your tip worked great for me. I have a iphone 2G, used redsn0w to jailbreak and unlock. Tried all kinds of stuff to make it work (hours lost), finally found your suggestion. Two minutes later, I’m up and running.

I believe Apple makes this bug so that make time for ATT to upgrade network. Just a bund of cowards. Boycott Apple productions (iphone as well as itouch)

no i have tried,but it doesn’t works. i bring it for service and they changed to brand new iphone for me for free. i was really surprised and was happy. from that day i am keeping my handphone safely. so i may suggest if it have been 12 months since u bought the iphone, u can ask tham whether is it possible to change the iphone to brand new one as singapore singtel had the good heart to change it for me.
