Iphone 3G suddely won't connect to any wifi network

Hello, my IPHONE 3G suddenly stopped connecting to my home wifi; before i have no problem. Lately it stopped connecting but after turning it off/on it works again. Now, a few hours after updating to 2.2.1, it can't connect to wifi anymore, I was surfing then it disconnected. I tried everything, reset, factory default and even resetting my home wifi router but no success. Interestingly, other 2 ipod touch and 3 laptops have no prob with my home wifi. Please help...

Thanks for your reply.
Yes, i believe it is already a hardware problem because I tried everything. And yes, I cannot connect anymore to other networks which i usually get connected. Although my iphone can see those wifi networks but can't connect anymore.
My prob is my iphone is ordered from a store in the philippines and that store bought it in Hong Kong, this is an open line Iphone 3G. I checked the warranty online and it says up to Oct. 30 this year. I hope they will fix this at Vancouver Apple Store. I have an appointment to the geniuses there today.

IPhone 5 won't connect to any wifi networks

I have had my iPhone 5 for aabout 3 months or so. And a few days ago, it stopped wanting to connect to wifi. I have tried connecting to other wifi networks, so it's not just our router. I have also tried turning LTE off, connecting, and turning it back on. That worked for a few minutes, then stopped. I have tried forgeting the network, and reseting my network settings. Nothing is working. Thanks.

No, not yet. I've decided to just send it in to apple sometime soon.

I just downloaded ios 6.1 on my iphone and now i cannot connect to any wifi networks on my mac

Can someone help here?

Updating iOS on your phone would not have any effect on your Mac.
What exactly is the problem?

My phone (4s) won't connect to any wifi since the ios7.0.2 upgrade

Since updating to 7.0.2 my iphone won't connect to any wifi network. I've done all the steps in help from forgetting the network to a full software reset and setting the phone up as a new device. Vodafone assured me that the next upgrade would correct the problem, it hasn't! They are now refusing to honour the warranty because the phone is now beyond its warranty ( due to waiting for the upgrade ).
I've Been assured by the tech guys at the local apple store that the problem is not hardware because the phone can see the networks.
Anyone know if apple have any plans to fix the wifi problem any if so when ?

Yes I've already restored the phone, once unconnected and again via iTunes, both times I set it up as a new phone and didn't restore the data or settings, I also deleted the iCloud account first so it couldn't backup from the cloud. The fault was exactly the same each time.
As far as the warranty I'm sick of arguing with Vodafone, the phone was in warranty when I reported the fault so you would think that they would honor the warranty, however I'm told by Vodafone that when I asked for a repair the warranty had expired.
Apple tell you all about European consumer law which provides additional protection, when you look into this it is advisory only and has no enforcement powers ( I've checked this with the ecl website).
Basically I'm stuck between two multinational companies that appear not to give a s*** about their customers!

you have definitely tried the correct steps, all you would need to do now is a back up & restore to factory settings. If after that the issue remains then you would most likely need a replacement unit.

TS1398 Update iPhone 4s to 6.1.3 (10B329) now I can't connect to any wifi networks at home or at work and all car Bluetooth systems will not connect either. Help! Extremely annoyed at apple for putting out software that causes such mayhem.

My iPhone 4s has been update as I said in subject bar.. Now can't connect to any of my cars Bluetooth systems. Also even more frustratingly can't connect to any wifi networks at home or work!!
How can apple put out such an update that causes so much grief and inconvenience to hundreds of people. Not to mention risking lives with Bluetooth kits not working...outraged!!!!!!

First, grow up. Just because YOUR phone isn't working, doesn't mean Apple put out bad software. I've not had any difficulty, nor has anyone else I know. And just how is Apple risking lives with Bluetooth kits not working? It's YOUR decision to talk on the phone or text and drive. Not Apple's.
We're users here, volunteering our time to help others. Posts like yours, which are whiny and ranting, simply means we're likely to ignore you and not provide you with any help. Not to mention, it makes you look absolutely foolish.
Further making you look foolish is the fact that you haven't even asked a technical support question, nor have you provided anyone here with any troubleshooting steps you might have taken, including those recommended in the user guide.
Good luck getting help.

My iPad 4th generation refuses to connect to any wifi network

My iPad 4th gen refuses to connect to any wifi giving a 'unable to join network' message and when on the rare occasion does is extremely slow, is this a hardware problem?
This problem came on suddenly after I couldn't connect to a hotel wifi whilst on holiday. I reset my settings completely to try and fix the problem but now I cannot set up my iPad because It won't let me connect to the wifi.
Please help!

Some things to try first: (some of these you have already tried)
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Can't Connect to any WiFi network

I just got my iPhone yesterday and I'm already having a serious problem,I can't connect to any WiFi networks.
I can see the networks around me and I can select networks that I've setup and I know are open or I know the security passwords, I can even enter the network passwords for the ones that require them and it accepts them without complaint. When I select a network I get a little check mark next to that network which I assumes means it should be connected to that network. However, the iPhone never actually connects to them, i.e. no IP address, no router no nothing in the network settings screen for each network, and always appears to the using the Edge wireless network when accessing the internet.
I've tried DHCP and static IP but neither works.
I updated the phones software to 1.1.4, has anybody reported problems like this with this or any version of the software.
Any help would be much appriciated.
If I can't get this resolved today I'm returning to the AT&T store tonight for a new one.
Thanks
Matt S.

theevilone,
I have personally used an iPhone with routers from D-Link, Netgear, Linksys, Apple and Belkin.
Some routers, regardless of manufacturer need to have their firmware updated. Generally speaking if you look at the release notes, the same updates that resolve issues with DHCP for game systems and PDAs, also resolves them for the iPhone.
In addition hardware or MAC address filtering can cause issues where you connect to the network and not get DHCP.
Hope this helps,
Nathan C.

My new Macbook won't connect to my wifi network - it keeps saying "password incorrect" - but I've tested it on my phone and works fine, I've checked the password I enter is correct digit for digit - what could the problem be?

My new Macbook won't connect to my wifi network - it keeps saying "password incorrect" - but I've tested it on my phone and works fine, I've checked the password I enter is correct digit for digit - what could the problem be?

you need to open the keychain access located in your utilities folder in the applications and once in the keychain on the left side click on the words system at the top and in the lower section click on passwords
next look in the striped area for any passwords that say airport network password next to kind and highlight those and hit delete on the keyboard to remove them from the keychain.
once you remove all of these airport passwords, quit the keychain
turn wifi off then back on, select your wifi network from the list and enter the password telling it to save to keychain this should resolve your issue!

IPhone 6 Plus won't connect to 2.4ghz networks but can see them

I just got an iPhone 6 plus that won't connect to any 2.4ghz networks. It will either say wrong password or unable to connect.
On my home network I had to change the band to 5ghz to be able to use my wifi and not all of my home devices are compatible.
Places that I went to test wifi:
McDonald's
Starbucks
Local Sports bar
Friends house
Does anyone know a fix? I tried resetting the phone, resetting network settings numerous times, turning off wifi networking in the privacy settings. Nothing seems to work and I am super frustrated. Can someone help?

I have tried replacing the phone, updating router firmware, running namebench to find fastest DNS, multiple reboots of phone and router, nothing helps. 5GHz band works like a charm but it doesn't penetrate to all rooms of the house. One guy said problem was solved by running beta version of iOS 8.2 but I don't know how to download it. Any success?
