IPhone 3G - iOS 4.2.1 - WiFi Refuses to Connect.

As it says... my iPhone 3G has refused to connect to the internet using Wifi.
Bit of history on it... It was a Telstra phone, and worked perfectly with WiFi, but since it was racking up unknown $3000 bills per month we decided to switch it to Optus, and it still worked fine.
Ever since we have swapped SIM Cards, or upgraded to iOS 4+ the WiFi just refuses to connect. It will pickup the router fine, and will say its connecting but then say it cannot and I have to dismiss the notification.
Any ideas? Solutions? Workarounds?
Thank you in advance.

There is no solution available other than selling it and putting the money towards a new iPhone.

Installed 10.8.4 and now my wifi refuses to connect to any WPA2 network!

Installed 10.8.4 update yesterday in the office. After restart my wifi refused to connect to the network although it was connecting to it fine before the update. Used ethernet and downloaded the Combo update. No improvement. It connects to the public wifi but not to the WPA2. Went home and opened my MBA and found that it does not connect to my peronal WPA2! Removed security from my Guest network and it connects fine. Put the WPA2 back, and it refuses to connect. Any ideas?

seems the problem is that the 10.8.4 didn't install properly. here is the install log:

If no change after restoring the iPhone with iTunes as a new iPhone or not from the backup, there is a hardware problem.

I recently updated my IPhone to IOS 7 and now it will not connect to my iTunes

I recently updated my IPhone to IOS 7 and now it will not connect to my iTunes.

You updated you're phone to 7.0.6? Thats impossible since you can only update to the newest OS version Apple released which is currently 7.1.1. Unless you updated before April 22 and just now posting you're question.

Upgraded my iphone to ios 5 now the wifi settings is greyed out saying "no wifi"

Hi today i update to IOS 5 on my Verizon iPhone 4 and now my wifi doesnt work. When i go to configure my wifi place next to were it says wifi in the settings is greyed out and says "no wifi". i obviously cant tap it and configure it. I dont know what's going on! it was working on IOS 4.2.10 literally 2 minutes before updating and now it doesnt work! i have NOT dropped my iPhone or spilled anything on it. The update seems to have "killed" my wifi. if anyone can help me that would be greatly appreciated seeing as to how i dont have unlimited data and need wifi

I'm having the same problem with my AT&T iPhone 4.
After installing ios5, WiFi was greyed out in settings. I turned my phone off and back on, and wifi was back. It saw my 2 routers, and allowed me to input my WEP passwords for them, but then, when I went to an app that used wifi, Safari, it wouldn't connect, and listed "Not Connected" Going back into WiFi prefs, it appeared to be searching for networks, but didn't find any. Not my 2, nor any of the neighbors. I usually see 3-4 networks other than my own.
Turn it off and on again, WiFi greyed out again.
Reset all settings - Wifi back, but with the same results as the first time.
Reset network settings - Wifi still greyed out.
I see this has happened at other new iOS releases, but never to me. Hopefully there will be a patch soon. I do have unlimited data, but dang 3G is slow.
I'm going to back up my phone this morning, and do a restore to factory settings, and see what that does, besides totally screw up all my apps.

IPhone 4s ios 6.1.2 wifi is work ???

anybody is know wifi is greyed or work in iphone 4s ios 6.1.2 ?????

Bad news guys.
My stuff doesn't work anymore.
No WIFI and i don't for Bluetooth.
I've reinstaledl the 6.1.2 using iTunes with the 4S as new but that was not a good idea ... Maps of my coPilot can't be downloaded because no wifi.
Apple take a quick action to solve this issue ... iPhone is one of my professional tools ... If no solution by the end of next week ... Bye bye iOS and welcome Android ...
PS: no problem with 6.1.2 on my iPad 2 WIFI.

Iphone 4 ios 6.1.3 wifi weak signal

Can anyone help, I have just bought a second hand iphone 4 but it looses the wifi signal if the phone is greater than 2metres from the wifi router. We have 2 other iphones in the family that work ok so its not the router that is at fault.
The iphone is on ios 6.1.3.
I had new covers fitted and at the same time the person installed a new wifi board but it did not improve the performance.
thanks

TS1398 After updating to iOS 7 my iphone 5 won't show any wifi networks or connect to any wifi even after resetting the network connections. HELP!

After updating my iphone 5 to iOS 7 my phone won't show any wifi networks or connect to any. I reset the network connections and still nothing.

I Just found it on the apple site, it arrived on a cd a few days later and worked just fine again.
i would recommend backing everything up just in case. Better safe than sorry, trust me. I've lost so much when i didnt back up once when re-installing the system.
IT shoulldnt erase everything, bt it might, so back up just in case
should you loose everything, then i have some tips on moving stuff fromyour iphone/ipod to the computer

Signals drop on iPhone 5s iOS 8.1 both wifi and network

I am having the following problems since i updated to iOS 8.1 on my iPhone 5s 16GB model A1533 :
1- My network signals drop to 3 dots and sometimes to 2 and stay there.
2- Sometimes my wifi disconnects itself on my iphone for almost 4 or 5 seconds
3- My battery is draining faster that ever. I turned off the use of fingerprint and found it useful but still my iphone consumes a lot of battery. I get my battery percentage dropped to 80% from 100% in just 20minutes of whatsapp usage. My fone's vibration is never on. Location services all off except find my iphone. Background app refresh also off. I tried everything. Erase all settings, hard reset etc. NO USE
4- Playing games is really difficult. Battery drains very fast.
I did not have these problems on 7.1.2. Need help
Regards,
Ahmad

I understand that but I hope that people from Apple will be referring to the support groups and may actually think about that last paragraph.

TS1398 iPhone 4 IOS 5.1.1 can no longer connect to my home wifi.

I upgraded my IOS using the latest version of iTunes on my Win 7 PC. Now, I'm unable to connect to my AT&T U-Verse wifi. When I try, I get the message "Unable to join network". I tried restarting the iPhone. I tried restarting my wireless router. I tried resetting my network settings on my iPhone. Help...

I've tried the following:
* Settings | General | Reset | Reset Network Settings (Twice)
* Settings | General | Reset | Reset All Settings (Once)
* Plugging it in and doing a "Restore" through iTunes (that's how I downloaded iOS 5.1.1 in the first place)
All the passcodes and restrictions are are turned off.
When I first try to connect to the network, I'm prompted to enter my username and password (I've elected to "forget" the network a few times so I can get this screen again). If I enter it wrong, then I just get an error that I'm not connected. When I enter it right, I get a warning that the certificate is "not verified". When I click on "More Details", I can see all the information that got pulled from the network (Issuer Name, Signature Algorithm, Public Key Algorithm, Key Usage, etc.). When I choose to "Accept", I get the little icon indicating that it's trying to connect...this never goes away (I let it run for an hour).
The encryption type on the main Wifi I'm trying to connect to says it's RSA (I'm guessing it's WEP though...I didn't set it up, our IT group did that).

IPhone 4, iOS 6 update, and wifi - cannot browse WWW via DNS

Apologies for the long post in advance. Hopefully it's exhaustive enough for Apple to take notice.
tl;dr:
updated iPhone 4 (VZW) to iOS 6 on home wi-fi. now phone will not browse to WWW on home wi-fi, EXCEPT WHEN BYPASSING DNS (ie, browsing by IP address). tried lots. no success
full events detail:
I updated my iPhone 4 to iOS 6 yesterday evening (via iTunes on my Win 7 x64 PC). Upon completion, I ran into some trouble trying to sign in with my AppleID in order to restore from my iCloud backup. Suspecting that Apple's servers were just experiencing trouble (though nothing indicated iCloud was down), I skipped signing in and went about my day. The rest of my settings copied across from my computer. At that point, I slept on it.
The following morning (today), I noticed that I still could not sign in, but was off to work and did not have time to examine it further. At the office, all seemed well, and I used the phone with the updated OS largely without issue, including connecting to two new wifi networks. Returning home, however, I noticed that the behavior was the same as the previous evening, ie I could not connect to things like the App Store in order to install updates, the web to look for information, etc. Now having time to troubleshoot, I pressed forward with the investigation and immediately found a number of support community and web threads detailing wi-fi issues on devices after updating to iOS 6. I followed the steps I found, but I still have the same issue. Below is the list of things I've attempted, to the best of my ability to recollect.
1. forget network, rejoin - same symptoms
2. power off phone, power on - same symptoms
3. set wi-fi network HTTP proxy to Auto - same symptoms
3. forget network, power off wi-fi, power off cellular data, power on wi-fi, rejoin network (same symptoms), power on cellular data (same symptoms)
4. power off bluetooth (already done, no change), power on bluetooth - same symptoms
5. forget network, airplane mode on, power on wi-fi, rejoin network - same symptoms
6. clear cookies, cache, website data - same symptoms
7. try another browser (Opera) - same symptoms
8. try static IP on wi-fi network - same symptoms
9. forget network, power off router, turn off wi-fi, power off phone, power on phone, reset network settings, power on wi-fi, power on router (after 5+ mins), rejoin - same symptoms
10. restore phone to factory defaults (same symptoms) and restore from backup (same symptoms)
11. enable SSID broadcast on router - same symptoms
12. enable WMM on 802.1n router - already enabled, same symptoms
13. disable 40MHz channels on 802.1n router - same symptoms
14. set router to 802.1g operation - same symptoms
15. remove wireless security from wi-fi network - same symptoms
16. change SSID - same symptoms
17. update router firmware - no updates available, also, same router was working prior to update and continues to work without trouble with all other wi-fi devices in the house
18. try another router - already verified this works, but as a result of the particulars of this case, is not relevant as my home router is not at fault, so much as the update to iOS 6 is on my iPhone 4. as other routers work and as a factory restore did not resolve (prior to backup restoration), I also do not believe my iPhone 4 to be at fault, so much as the software update itself
Having exhausted all of those suggestions, I dug further. The phone was working without issue up until the moment it needed to reboot to apply the downloaded iOS 6 update. I initially encountered the incorrect password scenario during the post-update configuration, but after forgetting and setting up the wireless profile from scratch (from the iOS 6 setup wizard), it joined my wi-fi network. The phone DID pull an IP address from my router, and responded to pings from other devices on my network without issue. In addition, using the Safari browser to web to a local network device, such as my router, was successful, indicating that the wi-fi network was established and routing appropriately. All other devices on the network, wired or otherwise, were working without issue. I then attempted to trace traffic and found that none of my phone's web requests were reaching my router, except for those targeted at the LAN. I then tried browsing to an IP to ensure there was not a DNS issue, and my phone browsed successfully. I then tried another site by domain name and failed, and then its IP and was successful. I verified against my router's logs that the web requests were routing through it to ensure that my cellular data wasn't taking over, and the logs confirmed it. At that point, I tried changing DNS from my standard servers to another set, but the behavior remained the same. I then tried setting my router as the DNS server, but the issue remained.
In conclusion, it appears to be some sort of DNS issue specific to the update. I would also hazard a guess that this is impacting people on the networks where they downloaded the update and/or were connected when the phone actually updated. I've tried setting the profile to use local, ISP, and public DNS servers, but as the requests never reach my router, I am inclined to believe it's being restricted by a setting on the phone itself. Because the problem persists through a factory restore, it would seem to point to all data not being truly erased during that process. Recall that I'm having the same issue prior to a backup being restored to the device, and that this issue prevents iCloud from being accessed during the setup process while on the problematic wi-fi network, so that should rule out the backup playing any part in the trouble.
Any thoughts?

The OP is correct, I have done many tests. With IOS6 there appears to be a dns issue in some cases with IOS for both ipad(2) at lease (my wife won't let me upgrade here v1) and the iPhone4s in my case. Pretty easy to diagonse, I wish Apple would fix it.
1.) I use a Juniper 5GT wireless firewall and all of my other devices (many apple, ipad, MBP, iMAC,3 ipods etc) are fine: Not ipad2 or iphone4s running IOS6
2.) after upgrade nothing worked. narrowed it down by messing with dns (I have my own dns server)
3.) Strange thing; dns works over MiFI (Verizon) and Carrier
4.) confirmed that it is a dns and not network issue.
-down load free tool called ping-scope-lite. (obviously you need to turn off wifi to do this)
http://itunes.apple.com/us/app/ping-scope-lite/id431500107?mt=8
turn on wifi
- ping Level3 dns server 4.2.2.2 or Googlesdns servers 8.8.8.8 or 8.8.4.4 these worked.
-now ping by name google.com or ipchicken.com
- try others; same result.
Apple did say that they would give me another iphone 4s: I just wasn't sure that would fix my issue. I tried downgrading to 5.1.1 but I got an error saying my device wasn't able to do so (tried even blocking itunes from contacting Apple) I whis this could be fixed. I did even have it working using my own dns server but now I can see that my phone over wifi isn't even trying to make a dns request now.

IPhone 4S/iOS 7.0.4/WiFi Grey Out Issues

My iPhone 4S (64GB memory/ATT) was working beautifully on iOS 5.1.1. WiFi connected seamlessly with Access Points at home, work, etc.
Then I made the mistake of wirelessly updating to iOS 7.0.4. Instantly the WiFi stopped working and the <Settings>, <WiFi> tab was greyed out and non-responsive. Oddly the WiFi tab on the Control Panel was responsive, but did not actually activiate the WiFi chip or open a connection to the WiFi antenna. Accordingly, there is no option to find or connect to a WiFi network.
Most other features appear to work, including the ATT cellular service and Bluetooth connection. However, the iPhone is slow to respond to some apps, For example, tapping <Settings> takes 5-6 seconds for a response whereas with iOS 5.1.1 the response was instantaneous. Also a few apps (even after updating) and a couple of iOS pages now cause the iPhone to go blank for a few seconds or crash.
Sounded like either an iOS or firmware issue to me.
I followed all of the Apple and ATT suggestions, including:
-Confirming that the iPhone is not in Airplane mode.
-Turning the iPhone off, waiting, and restarting.
-Forcing a hard restart of the iPhone by holding the <Silent> and <Home> keys simultaneously for 7 seconds.
-Resetting the network settings by tapping <Settings>, <General>, <Reset>, and <Reset Network Settings>.
-Checking for a newer iOS (none).
At the suggestion of a couple of ATT support representatives, I tried even more drastic measures:
-Resetting all settings by tapping <Settings>, <General>, <Reset>, and <Reset All Settings>.
-Resetting all content and settings by tapping <Settings>, <General>, <Reset>, and <Reset All Content and Settings>.
-Backing up, Restoring iOS and firmware, and Restoring applications and data using iTunes.
-Restoring iOS and firmware using iTunes, and then setting up as a new iPhone.
-Turning off iPhone, waiting while ATT pushed a new switch data pack to iPhone, and then restarting iPhone.
Actually I did all of these "fixes" at least twice with the same result: still a greyed out and non-responsive <Settings> <WiFi> tab with no WiFi signal.
Apple and ATT's ultimate solution was predictable: Buy a new 64 GB iPhone 5 for several hundred dollars (plus numerous proprietary cables) and forget the 47 GB of data, photos, etc. lost beta-testing their iOS and "fixes".
Any "fixes" that I missed or other suggestions?

ChrisJ4203, thanks very much for your input. I don't mean to turn this post into an endless debate, but frankly I am still having a hard time believing that the WiFi died as a result of a hardware failure.
My logic might be flawed, but here it is:
While the iPhone 4S got very hot when wirelessly downloading and installing iOS 7.0.4 over the WiFi network, the WiFi chip and antenna had to be functional to complete the wireless iOS update. Apple was very clear that iOS 7.0.4 is too large to download and install via cellular service. Accordingly it would appear that any hardware failure had to occur in the few minutes between the download/installation of iOS 7.0.4 and its first use. That window of opportunity is incredibly small in an otherwise flawless hardware performance. I am not a big believer in long shot coincidences, so a WiFi hardware malfunction seems highly improbable to me, but not impossible. A firmware/iOS conflict still seems more plausible to me.
I also don't read much into Apple's "out-of-warranty" replacement offer at $199. AT&T tells me that anyone walking in off the street (with or without a hardware or iOS malfunction) would receive the same offer.
I appreciate that some iPhone 4S users did not experience any WiFi issues when they updated to iOS 7.0.4, but such difference could easily be explained if Apple used more than one WiFi chip and/or firmware in the iPhone 4S series. Such an explanation would also account for iOS 7.0.4 (and 7.0.6) not recognizing the WiFi chip after the iOS update.
Still perplexed, but thanks again for your kind efforts to help.
Wonder if I can limp along long enough to spend my money on an Apple iPhone 6 ... but then again I don't want to be anyone's beta-tester.
I am tempted to switch to a Samsung Galaxy or some other smartphone as long as I will be buying new accessories, but frankly I don't want to waste my time learning a new OS or core apps.

HT4623 I updated my iphone with IOS 7 and my wifi and bluetooth is not working. How can I go back to IOS 6?

I have updated my iphone 4s with the last version IOS 7.0.2.
At the beginning my screen freezing each time I enter numbers or letters (in iphone security code as well as texting in any app)

How can I go back to IOS 6?
My iphone will be working correctly again???
Thanks!

Downgrading the iOS is not supported at all.

IPhone 5 iOS 6 FaceTime on wifi and 3G bug

Think this is a bug. I have iPhone 5 with latest IOS 6.0.2 I think.
When I have 3G mobile, but not data enabled and I have a wifi connection FaceTime does not work and says 'connecting' but no connection is ever made.
If I change the settings to 3G with data or wifi only with no 3G then FaceTime works.
At home I have a 3G signal booster connected to my router as I have poor mobile coverage in my area do the 3g signal booster is a must have.
I don't like having 3G data on as well though as this drains my battery quickly and is expensive on data costs From my provider.
Tried to log a bug with apple this is easy to replicate.

using facetime http://support.apple.com/kb/ht4319
troubleshooting facetime http://support.apple.com/kb/TS3367
So if I understand you correctly when you have 3G data turned off and on wifi - you can't use facetime.
YOu can use wifi for facetime - the other party needs to be on wifi or cellular data.
You can use cellular data for facetime only if your cell providers offers that.

IPhone 4 IOS update on home wifi never successfully completes.

I've never been able to successfully update my iPhone 4 on my home network since I first purchased it a couple of years back. I've asked at the Genius Bar on previous occasions but was offered no solution, was merely explained that there might a wifi issue. When I try update my iPhone goes into update screen with apple logo on top and a completion bar at the bottom. The completion gets to about 75% complete then that's it it doesn't go any further. Then I'm left without a useful phone cannot make phone calls cannot look up contacts cannot call apple for support ! Then the only option is to go into apple store to update on their computers. I've had to do this several times since I first purchased the phone, and was left with well, many questions, the main one being why ? Why does the process complete on apple store wifi but not at home ?
Quite unhelpful that I've never been offered an answer, hence I've never upgraded my iPhone to a new one.
It's very inconvenient as the first time it happened I was left without my only form of contact, I didn't have any phone numbers, and didn't have the time to fiddle around with phone updates, I merely tried updating as I thought it was a simple quick process. Instead it turned out to be. Very time consuming. A it must be to read this account of my experiences with my first iPhone, so ill end it here !
Would be nice to finally be offered a solution. It certainly would be more convenient as I don't update my iPhone 4 at because I know from past experience ill be left without a phone.
BTW a interesting interesting thing happened the other day, I did a backup of my phone, and by chance went into the broadway apple store and she I later walked out notice my iPhone had lost all contacts and apps and notes were not there it was like it got cleaned out!
It was ok before going into the apple store. Any ideas ?
Thanks guys

3. How do I clean my phone to recover space?
4. If I do clean my phone to recover space with itunes, or a restore will the IOS update I don't want be forced on me?
1. The only way to remove it is to install it.
2. No, because the only way to remove it is install.
3. The only way to recover the space is to install it.
4. If you restore, it will install the latest iOS, 7.0.4.

IPhone 3G - iOS 4.2.1 - WiFi Refuses to Connect.
