How do I fix iPhone Wi-Fi connection problems?

Some users have reported issues with slow speeds or trouble connecting to Wi-Fi networks with iPhone OS 3.0 and later firmware. iPhone owners who have jailbroken and/or unlocked their iPhones using blackra1n and blacksn0w have also reported problems.

These problems include the inability to connect to Wi-Fi, 3G and/or Edge, lack of push notifications and issues with the YouTube application. Fortunately there are several fixes you can try to correct these data issues on your iPhone:

1. Reset network settings. Touch Settings -> General -> Reset -> Reset Network Settings.

2. Still having problems? Touch Settings -> General -> Reset -> Reset All Settings. Warning: You will lose all of your preferences.

3. For YouTube problems on jailbroken iPhones try installing youtubeFix from Cydia or another package installer.

4. Restore your iPhone as a new phone. This is a slow and tedious process but will reset your iPhone as if it was new from the factory. Although this should fix all of the above issues, you will have to reload your contacts and media onto the iPhone from the computer manually. To restore:

- Connect your iPhone to the computer.
- Run iTunes.
- Under the Summary tab select Restore.
- Select backup if you wish. When restoring as a new iPhone you will not use the backup.
- When the process is complete the iPhone will restart.
- When the Set Up You iPhone screen appears select Set up as a new iPhone.

Of course, after restoring a jailbroken iPhone you will lose the jailbreak and unlock functionality.

iPHONE 5 UPDATE: There are limited circumstances where iPhone 5 users are experiencing slow speeds or intermittent service when connected to Wi-Fi. There are two fixes that might help.

1. Entering manual DNS settings has been reported to help. Navigate to Settings -> Wi-Fi and touch the blue arrow next to your connected Wi-Fi network. Touch DNS and enter Google's DNS server address (either 8.8.4.4 or 8.8.8.8).

2. Router compatibility issues could mean that WPA2 Personal W-Fi security is causing the problem. Switching to WEP security or removing password security altogether can improve Wi-Fi speeds and connectivity.

Okay so I've been having problems with my second gen iPhone. I had downgraded to 3.0 firmware and jailbroke/unlocked it with redsn0w. Everything worked fine the first few days, but then the wifi started messing up, and now it doesn't work at all. I've been following tips from various sources such as restoring my iPhone, resetting network settings, resetting all settings, and even just resetting my router. Nothing worked and I'm pretty much thinking that my iPhone is just bricked. Anyone have any suggestions on how I can possibly fix this, or should I just wait until the next update and jailbreak method?

Exactly in the same situation. Jalbroken with redsnow and suddently no more wifi. As I got a nexus now (unlocked) I thought it was not a problem to load the last 3.1.3 from itunes and that would resolve my problems, as the only use I give to my iphone now is wifi from home. It didnt work and now that I start reading possible solutions, only now, I find that I should have stayed forever with my jailbroken if I wanted to be safe.
I have not yet installed as a new phone, but that comes next, and possibly then the wait for the next jaibreak, if it ever comes. In the meantime I have a useless iphone

Hi, I am having troubles with my jailbroken Iphone 4 recieving wif signals.
I have the very same phone unjailbroken and it picks them up right away.

The one I jailbroken was working fine, but it now is increasingly harder and sometimes impossible to have it pick up wireless signals that I can see are there on my other unjailbroken phone.

The jailbroken phone is version 4.2.1 (8C148), 03.10.01 baseband

I saw the postings about using wififofum, but when I go there there are iOS 5 Update Warnings

Do you have any idea what I could do? Should I change my base band?

Also, I am able to pick up a wifi very well if I am right next to it. Could it be an antenna problem or hardware problem??

dude i have the same problem and its either gunna be a software problem or a hardware problem

I am having a similar problem on my iPhone 4S.
I have installed WiFIFo... But it's not allowing me to connect to my network as it is greyed out.
Any help?

Hey can you teach me how?

I have an iphone 3g running a 3.1.2, modem firmware 5.11.07.
I just suddenly lost my wifi connections. Tried everything- reset all settings restored it, erase all content, put it in a freezer, name it all I have done everything!

Did you use Blackra1n or pwnage tool to jailbreak it?

PLEASE HELP ME! REALLY GETTING FRUSTRATED ABOUT THIS WIFI ISSUE!

i have the same problem, could you fix it?

Hi guys,

I had exactly same symptoms, worked, then suddenly....lost wifi...Reset settings etc... no way.

SOLVED: Install from Cydia "wififofum" to search for wifi... and it unblocked the situation :-)))

"Wififofum" = the bomb. After months of no wifi on jailbroken 3GS, 60 seconds and done. Thanks, ungaru!

THANK YOU!!! it worked for me!

What is the source for wififofum? I've installed Cyder on my PC to install it (as the phones wifi is not working) but the package is not showing up. Any hints?

THANK YOU! Wififofum worked for my husbands unlocked/jailbroken iPhone 3G running 3.1.2 on firmware 05.11.07

He suddenly could not connect to the wifi here in our house. Or any wifi anywhere. Ran Wififofum and tried to connect again. This time rather than an error message it asked for password. Inputed it and he's off and running again! THANK YOU!

I don't understand how wififofum unblocked your wi-fi problems. Because when I installed it, it says 'wi-fi must be turned on', but how can I do that when my wi-fi option is greyed out? I'm really desperate now, and if you could please share how you fixed your problem, i'd be soo grateful :)

i have the same problem as u..how can i bring back my connection on wifi?did u already solve ur problem???how??

My blackberry 8120 refuse to connect to the internet but keeps on asking for wifi connection. Please help me on how to connect my server

I have the same problem did u fix it and how?

Worked exactly as stated...thank u

how do you connect to cidia if you dont have service or a wifi connection?

How do you use Cydia with no wi-fi in order to fix wi-fi ?

Thanks

OMG Mee too!!
what is Cydia "wififofum"??

Thank you so much! It worked for me!!! :) I'm a happy puppy!

I hope though that this fix is permanent. I'm really getting frustrated about it already.
Tried all the resetting and erasing and even the freezer trick (which worked for 30 minutes btw but failed after I connected it to itunes) but nothing worked until I read your suggestion. :)

THANKS AGAIN!!!

For those who're wondering how it works...

your iphone has to be jail broken first. then search for wififofum in cydia.

try to use 3g first (that's what i did) to download the wififofum and stay on 3g until it works and stuff then just wait for the app to connect to the wifi. :)))

problem has only just started for me but wififofum fixed it thankyou :)
