iPhone 4 cannot connect to home Wi-Fi

thx for help everybody,

i'm at work right now, so when i come back home i'll try the security thing and i hope it will work.

but the question is, why is this happening??????

i'm sorry but it's really weird for me 🙂

i mean it used to connect normally without any problems even my ipad after i updated it to IOS 5.0.1 , it used to connect and everything was fine, but suddenly it stopped connecting :s

something is wrong and i hate it that i don't know what it is 😐

Hi, experienced much of the above: erratic connections at home, after an iOS upgrade. Been there for months.

BUT.

Today, I followed the advice given somewhere in this forum to give my iOS divices (iPhone 4 and iPad 2) a static IP-adress. The connection has been stable ever since.

Hope this works for you too.

I am having the same problem. My iPhone stopped recognizing the Wifi sync connection. It use to connect to Wifi when I plugged it into power, then I used the USB cable to connect and now it refuse to connect over Wifi. I am resetting the iphone and hoping that works

I restarted my computer and now it works OK. It is also syncing up although I don't have the iPhone plugged into a power outlet. My Sister's iPhone does the same thing. She just goes home, it detects the Wifi and starts to sync.

My iPad can connect to my home network and I get the IP address and all information from the router on it. My new iPhone 4S can see my home router but I do not get any IP info and cannot connect when prompted for the router password. The iPad just auto connects.

Hi again,

I tried almost all the suggested solution but nothing worked :(

When i come back home i'll try to change the static IP for my iphone, i hope it will work

If it didn't i'll have to buy new router :s

By the way i cancelled the password in my router but still not connecting.

My iphone can c the wireless router but can't connect to it, it's so weird

And by the my ipad 2 is not connecting either

I'm tired of this :/

I'll walk you through it. (I just hope that the UI labels wiil fit exactly; as I use the Dutch language version, I have to guess a bit for the English version)

Go to Settings and select the details of your home wifi network, using the blue chevron icon on the right.

You'll see a bar with DHCP selected, and most of the items like IP address filled. Take a pen and write them down.

Now click on Static. The underlying fields will empty. Fill them in with the values you just took notes of.

It might make sense to fill the DNS field with multiple server addresses, separated by commas. That way if one DNS server goes down, your system will be able to switch to another. I took a list of fall-back servers from my service provider.

Leave the page by clicking on the Wi-Fi Networks arrow in the left hand top corner.

That's it. Just for this network, you've now switched to using a static IP address. All other networks will still be using their own dynamic settings.

One more thing: if things don't work right away now, you might need to choose another IP address.

Just pick one that is a notch higher than the number of systems you use. E.g., my IP range starts at 192.168.0.1 (my WAP/router). The local DHCP server integrated in my router gave 192.168.0.2 to my iPad, .3 to my PC, .4 to my wife's Mac and .5 to my iPhone. If these addresses for some reason would not work using static IP addresses om my iOS devices, I would use .10 and .11 respectively. You might try something along these lines.

A guess as to what all of this means.

I noticed, just once, that my PC gave of an error message saying there was a conflicting IP address on the network. This got me to think the following.

Perhaps when the router sends network trafic to the iOS devices, every now and then for some reason they do not respond correctly. A dialogue ensues to issues a IP address to the iOS device. However, the device itself still assumes it has the previous address. Conflict.

When I switch the device to flight mode and back again the situation is resolved by flushing caches and then re-requesting an IP address. At some point in time, the whole thing will cycle again and again.

This erratic situation is bypassed by claiming a permanent IP address for the iOS device. Is simply will not request any new address, and any faulty response to network traffic simply results in a retry and some microseconds of delay. On the other hand, you yourself will now be responsible for handing out addresses that do not conflict with others.

For that last task, you might consider using some kind of LAN scanner. I use Advanced LAN Scanner 1.0 beta on my PC and Scany on my iOS devices. They'll give you a clear picture of what addresses are in use at a given moment.

If my guess as to the origin of all our troubles is faulty: just neglect it. It is neither here nor there anyway.

I hope my little instruction will be of some help to you: let me know!

I just experienced the same problem which can't connect to my home Wifi network. I read some other posts and tried below solution. It works on me. Details are as follow:

1) Choose: Settings--> General --> Network --> Wif-Fi --> Other...

2) Type in the name of your Wi-Fi network

3) Choose the "Security" i.e. WEP, WPA, WPA2...etc.

4) Type in the password then press "join"

It is working fine now. Hope this will solve your problem. Good Luck.

i had the same problem if you have updated to the new ios here is what you do to restore wifi for iphone 4 go to settings and then click general then go to VPN turn off and then turn off cellular data and make sure your network is enable (e.g Enable 3g) depends on what company you are though and then your good to go.

hope this works for everyone

Hi folks.

I has this very problem when I bought my new iPhone 4s.

Although there can be problems with WiFi connectivity that require a Network Reset (under Settings/General/Network Reset), the actual problem is quite easy to fix....

A Home WiFi Wireless router has a limited amount of stored devices. If you think about how many you have (PC, phones (plural), PS3, X-Box, Smart TV etc, etc), and then factor in how many friends use your connection when they are in your home, then it can quite quickly run out of space.

If that happens when you try to connect your shiny new Apple device, then you will not connect.

The answer is to carry out a full factory reset of your Wireless Modem/Router.

I'll use my Orange LiveBox as an example;

Press the "Reset" button with a pin, which will wipe all internet settings and saved profiles.

After it has run it's setup, you will have to re-enter your internet username & password. Once that's done you will need to re-pair all devices in your home (including your new phone). While you're doing this it's also a good idea to change your broadcast channel (usually set to 6 or 12). Trial & error may be necessary depending on what your neighbours have done, but I found 4 or 10 give a good and stable signal (no more dropped connections).

DO NOT TRY THIS IF YOU DON'T HAVE YOUR INTERNET USERNAME & PASSWORD!!!!!!!!!!

IT WILL WIPE YOUR SETTINGS.

As an addendum; I have read quite a few posts in this thread, and can sympathise with a lot of you. The answer the Apple Tech Guy gave was correct, but unhelpful. As a company selling a LOT of these products, they should be aware of the usage habits of their customers. I hope that they use forums like this to broaden their knowledge base. This is something they should have been aware of, but were perhaps reticent to advise hundreds of people to reset their internet, & the deluge of complaints it could cause). Maybe we could meet somewhere in the middle?

Good Luck,

Ade.

Mmm, your reply may make good sense in some situations, but certainly not in mine.

I _did_ reset my router etc, to no positive effect. And, for a fact, I have never had more than seven or eight distinct devices on my net, neither at one point in time nor consecutively

BTW, my wife had similar problems with her MacBook. I had her switch to a static IP-address, and no more glitches.

My iPhone now is perfactly stable, my Windows devices too, the Mac, but my iPad remains reluctant to stay online all the time. Beats me.

Just to make things clear: before my iDevices no problem on the LAN ( I just had two Windows devices at that time).

After intruducing my iPhone and having a few upgrades, things went sour. Ahard reset of my WAP/Router did nothing to improve things. Giving al devices hard IP adresses removed most probelems; just the iPad2 remains a problem.

I have a mainstream & up-to-date Cisco/Linksys router, up-to-date OS versions on everything...

I do not have a real clue as to the undlying problem, and I am reluctant To blame anyone.

but: I havae to conclude that things started to go south when I introduced the iDevices.

Sure would like to really really know what's up...

hi guys, I am using iPhone 4 and iPhone 4S at the moment. facing the same problems like all the users here, good wifi at work, cafe, tapping from neighbours, etc but cannot connect at home. well, I managed to fix this issue last night with help of a fren after some try and errors. I am using linksys WRT54G and a ADSL modem.

plug your router to your notebook without connecting the your modem. goto setup by keying in http://192.168.1.1, user and password is admin.

make sure that your router ip is not the same as your modem ip. for my instance I key in 192.168.1.254 as my router ip.

thats it, it works for my iphone 4/iOS 5 and iphone 4S/iOS5.0.1.

after 2 months struggle finally the battle for me is over.

give it a shot !

I hate to sound like a broken record but I am having the same problem too. The only difference is my phone never connected to my home network. It will connect to other networks without an issue. I have a new 4s. I took my airport extreme to my local Apple Store and I could connect to the same airport extreme that was addeded to their network. Then I took my airport extreme to my office and connected it our network and again like the Apple store my could connect with no problem.

I bring everything home without changing any of the settings on the Phone or Airport and the issue comes back like before. It has to be something with my ISP I guess. I can't figure it out.

Greg, I even tried your airport mode and it worked at the apple store, job but not with home network.

Hi all, just to say I had this problem but it has now been resolved.

My new iPhone 4 had been "unable to connect to" my home wifi, despite having had no problems in two years with an iPhone 3. The new phone also worked fine on other wifi networks I'd used before, eg at work and a friend's house.

After reading countless discussion threads looking in vain for the fix I decided to call Orange technical support and, though it took a while when they went through all the obvious things (phone restart/forget network etc) we got there by effectively restoring factory settings on my router, an Orange Livebox.

The down side is having to amend password settings for all our other wireless devices, but the up side is iPhone 4 wifi on my home network...

Hope this helps someone.

My Iphone 4 was working fine up until a week or so ago, I am current on my updates (both phone and routers).

I have 2 routers set up in my residence one is an Apple Airport and the other a Motorola. I could not get on either as of about 2 weeks ago.

Tried various fixes - could get it to work with a Static IP, but this was not what I considered a permanent solution.

I went back and read a few posts in this thread, and one thing that I did not try, was just unplugging the routers.

I had reset them and changed the raido mode, etc. etc. I unplugged both routers for a minute or so, plugged them back in, and I am able to connect to both fine via my iphone 4.

So instead of trying some of the other suggestions first, go with the unplug and if that doesn't work, try some of the other suggestions.
