IPhone Internet over WiFi problem

Each time I try to connect to my WiFi network in my office through iPhone 4 (iOS 5.1) the WiFi signal disappears and appears again. I use proxy configuration to surf the web, and I can not enter the proxies in my WiFi tab.
Please help

Follow the steps here. If nothing works, make an appointment at an Apple store or with whoever handles iPhone warranty where you live:

  • TS1398 Having trouble accessing the internet over wifi on my iPhone 5.

    Hello, I have a nearly brand new iPhone 5 in perfect condition. So far, I have had not problems with it, however recently, I have had major issues connecting to the internet over wifi. Some things that would happen would be apps that require an internet connection time out, and pages don't load in safari, and the reliabilty would be off and on.However after switching the wifi off and going off of my 4g, the connection was fast and I experianced no problems. I am positive this is not a problem with my home network, because my household had lots of people and LOTS of electronic devices that connect to the internet with no problem. I also have an ipod touch 4th generation that has been able to connect and browse the internet with no problem, it's just the iPhone that is being slow. Also, this isn't really a consistant pattern, occasionaly I will get it to work for like five minutes with no problems then it just time out on whatever it's doing.
    Any help would be appreciated.

    Well it might still be the Mavericks Wifi issue... slow throughput on an apparently strong signal is part of its behavior from what I've read.  So to recap You got a signal (fairly Strong) appeared to be connected but Safari could not display the welcome page.
    I'll share something I do in a case like that. I use Firefox. I keep a copy of Firefox, Opera and Chrome on my laptop because some sites use non-standard web code and the different browsers "play" better with the server/router. Safari is a lot better than it was when it first stared out but there are some sites put together (especially financial sites) that just won't let Safari play (they can code to prevent that).
    If you have time between flights download Firefox and give it a shot... at this you have nothing to lose.
    Good Luck.

  • I can't access my Yahoo mail on Iphone 4s over wifi at work. "Checking for mail" is going on forever. Any idea?

    I can't access my Yahoo mail on Iphone 4s over wifi at work. "Checking for mail" is going on forever. Any idea?

    You cannot change the incoming mail ports on the iPhone,  As KiltedTim mentions, if it works elsewhere on 3g and wifi, then it almost certainly is your employers firewall blocking access.

  • Hi, recently my Iphone 4S having wifi problem. I have try to restore it and accidentally get everything clear off. I have also notice that my phone is not USB recognized by my laptop before my wifi gone. Is there any ways to restore my contact?

    Hi,
    My Iphone 4S having wifi problem. I also noticed that the USB is not longer recongnized by my laptop anymore.
    I tried to upgrade my IOS6 into 7 hopefully it work...
    Somehow, all data (contacts, sms, photo and etc) were gone after I did that.
    Since my USB and wifi is not function, is there anyway to retrieve my lost contacts?
    For Icloud, is the data retrieve via the phone sim? Phone mac ID? Apple ID? or everything?

    Did you backup your iPhone 4S before to upgrade? If you did, you may recover your contacts from it.
    iOS: How to back up and restore your content.
    http://support.apple.com/kb/HT1766
    Or you should use an iPhone recovery software to get your lost contacts back. Please follow the blog's tips to have a try.
    For iCloud, it does not retrieve the phone sim data. It can only restore your backup data. And, if you want to find your Apple ID, you should read this:

  • I updated my iPhone today over wifi.  It downloaded 6.1.3 completely and started then installed it.  After the install all it does is show the connect to iTunes screen.  What did I do wrong and now do I have to completely restore the phone?

    Next question.... I did an iCloud save point earlier today so in theory everything should have been saved and the restore won't be a complete loss right?  Please tell me my pics aren't gone.....
    Thanks for the help.

  • Unable to browse internet over wifi on my iphone

    I am unable to browse internet on my iphone 4 and ipad3 simultaneously over wifi.
    Both iphone and ipad show connected over wifi but only my ipad can connect to internet. Along with ipad I have no problem in connecting laptop and my other android phone over wifi and browse but iphone won't.
    I am using talktalk broadband. Please help

    Does your phone receive a valid ip address from your router?
    Does it work fine when connected to other wifi networks?  If so, then I'd say your router is the culprit.

  • No internet over wifi, bizarre problem

    Summary:
    I cannot access the internet via wifi, but can with a wired connection. There is one other computer on the network, connected via wifi. It has access to the internet. I can file share and VNC to this other computer either wired or wireless.
    So everything works exactly as I'd expect, except when I type in "www.apple.com" or whatever, the browser hangs and eventually says the server couldn't be found. Nothing outside of the network resolves, when I'm connected via wifi, except the machine on the local network (and the router/AP itself).
    I've rebooted my machine, and in safe boot, and I've rebooted the router. So I'm totally at a loss how this is even possible. Nothing has changed with the laptop or the router, or the network, in 3-4 days.

    Searched for "network reset" and found suggestions to delete the folder:
    /Library/Preferences/SystemConfiguration
    I did this, restarted and now I have internet via wifi again. I don't understand why or how it stopped working in the first place let alone how this fixed it or even if it did.

  • Iphone 3G and wifi problems.  I've been reading the string about this from last year.  I have an iphone 3G with the latest ios 4.2.1 software.  Every time I connect to my home wifi - Belkin N  - it comes up after a few minutes with "Incorrect Password".

    I re-enter the password correctly but it keeps happening.  Any suggestions?

    I have a belkin n surf as well and i have got this and other problems. my iphone 3g and 4 often keep on loosing connectivity. especially if the bluetooth is one (either connected or not). it often fails to find my wifi network after waking up from sleep.
    the problem i think is most certainly with belkin n. its one of the worst routers out there. unfortunately i didn't read the reviews before buying it. i have other problems with it to like connecting it to a dc++ hub. the setting up for port forwarding is a pain and it tends to connect to the internet on its own even though there are no settings to disable automatic connection.
    i was later told by many people online and also read it in the reviews that its one of the very bad router out there along with other belkin routers. belkin has even arranged a replacement for me as its under warranty but i'm avoidng travelling to the other end of the city cause i know all models have the same problem. the worst of them all is a mere 3mbps transfer speed form one computer to another over wifi file sharing even if they both are connected via 802.11n and are placed withing full signal coverage range, with no firewall or security on either on the machines or router. tried it over several macbooks and windows pcs.
    i'm getting lynksys for good.

  • Can't update media on iPhone 4S over wifi

    When I first made the switch to wifi syncing, everything worked fine.  I occasionally have to restart iTunes to get it to see the iPhone on my network, but I feel like that's to be expected.  But before I would go to bed, I would delete some movies from my iPhone and then drag a bunch over to wirelessly update during the night.
    But now, I am no longer able to interact with media at all over wifi.  I can sync just fine, but I cannot delete or add content to my iphone. As soon as I try, iTunes reports that it's "Looking for iPhone" and after a few seconds, it disappears from my device list.  And this can be just mere seconds after completing a wifi sync, so obviously, it can be "seen" by iTunes.
    I've tried it with my iPhone plugged in to wall power and unplugged. I've tried restarting iTunes.  I've tried restarting my iPhone.  I've tried rebooting my computer (Windows 7).  I've tried rebooting my wireless router.  And now I'm stumped.  AFAIK, no settings have changed, so I'm totally baffled as it used to work just fine.
    Can anyone offer any hints?

    Ok... apparently I found a way to update the lyrics on the iPhone 4S...
    I basically deleted the song from both iTunes and iPhone, synced it, re-added the song back to iTunes and synced it again. That solved the problem.
    FYI: I updated both the iOS and iTunes since I posted this question. So I’m currently running iOS 5.0.1 and iTunes 10.5.1 (42)
    Just in case I've included step-by-step instructions:
    (Assuming the Lyrics are showing up correctly on iTunes)
    In iTunes: Library>Music> Right-click the song> Show in Finder
    Copy (do not move) the file somewhere else (e.g. Desktop)
    Back to iTunes: Right-click the song again but this time Delete>Move to Trash
    On your iPhone: Music> select the tab for Songs, locate and delete the song from your iPhone. (just like when you delete an email or a text conversation -- swipe the song name and delete it)
    iTunes or iPhone: Sync
    Desktop: double click on the file to re-add the song to itunes. (but you will loose some info such as original date added, play count, ratings etc...)
    iTunes or iPhone: Sync
    The updated lyrics should be displaying now....
    Note: If you skip the first sync or don’t do exactly as described above, you may have problems getting the song synced back to your iPhone. In early attempts, the song would show up on iTunes but not on the iPhone.
    Sub-Note: Do it at your own risk.

  • ITunes 12 won't see iPhone 6 over wifi

    I have an iPhone 6 running iOS8.0.2 and a Macbook Pro with Retina Display running Yosemite and iTunes 12. The same problem I've always had is still there - iTunes will not see my iPhone over wifi. Sometimes it does, sometimes it doesn't. I can never predict when - if by some miracle it has, often it loses connection.
    Yes, they are on the same wi-fi network.
    Yes, they are both connecting to the net and getting 8mbps downstream.
    Yes, the iPhone is charging (a ridiculous requirement thought up by a moron).
    Yes I've tried restarting everything.
    This drives me mad - thought Apple was supposed to "Just Work". I've sat there and listened to Tim Cook et al describe the "seamless integration" as "magical". Yeah well my Sony Ericsson w880i "just worked" over bluetooth with my old macbook - that really was just magical - but my iPhone 3G, 4, 5 and now 6 never has - it's a joke - Apple make the computer, the phone, the operating systems and the music software and they can't get the two to connect? It's unbelievable. It's worse than Microsoft. Handover?? SORT THIS OUT FIRST!
    Oh, and after typing this whole question, I get "You are not allowed to create or update this content."
    What a bunch of losers - worst user experience ever.

    I know this is off topic, but does anyone know how to manually sync and eject your ipod from version 12.01.26 of iTunes? I just upgraded to this version and now I cant find the icon and cant eject my ipod.

  • Ea3500: no internet over wifi

    Hi,
    for some reason my ea3500's wifi network will have no internet connection occasionally, I am still able to access the router's gateway over wifi, even stream videos with plex. But no internet access. TheEthernet also worksfine..

    @strech1
    One of the probable causes of your concern is a corrupted firmware in your router. Doe your router have an EA Series Linksys Smart Wi-Fi Firmware or a Classic EA Series Cisco Connect Firmware? It would be best that your router have the latest EA Series Linksys Smart Wi-Fi Firmware installed. It would be best to update the drivers of the wireless adapter installed on your wireless computer.

  • IPhone has internet over WiFi, however email doesn't work over wifi

    Hi. I have wifi set up for work and home and I can get internet just fine, however when phone service is bad I can't send emails even if the wifi is full bars. At home my service is 0-2 bars and work I have nothing. Any suggestions?

    Check your Outgoing Mail Server settings. If only have your cell phone carrier's mail server (i.e. AT&T SMTP Server) selected it may only work when using cellular data. Try selecting another outgoing mail server if you have another list.

  • Iphone 3g having wifi problems - app problem?

    Hi,
    I just got given a iphone 3g as a hand me down, and I think im having problems with the wifi, but cant find anything sensible as fix (one video suggested put it in the oven)
    when using safari, or internet apps (namely, facebook, kik, igotchat) and probably any other apps that need an internet connection, I get randomly "disconnected" for lack of a better word. on safari it says "no network is available, please connect to wifi" and kik says the same thing.  normally with safari i can just refresh the page a couple of times, and it will work, but when using the instant messenger apps, it just doesnt send or receive my messages, for hours,
    the thing is, when all this is going on, i dont actully lose wifi, the signal symbol is there the whole time, I go into settings and my routers name is there, and also igotchat's wifi status always says its good.
    So far ive tried changing my wireless channel on the router, and also trying to use it on a diferent internet connection, but the problem still persists (my home network is fine on all other devices)
    i understand that im using "legacy" apps, and therefore not on the latest version, but im on the latest that ios 4.2.1 will allow, and im sure app developers/apple wouldnt just have people unable to use their old devices
    so what im asking is there any fixes i can try, either with the phone, the router, or the apps, as currently its fairly unusable as an internet device
    im pretty new to apple products (except my old ipod video) but im decent with technology so il try anything if it might help even slightly

    Hello monolith,
    So, you are still having the disconnection after changing the protocol to G only.  Another tip some folks have used to help clear this up, is to set up a Static address for your phone.  This is something I do at work, so I took the practice home. 
    Not all routers, will let you reserve addresses for devices, but some do.  If your router is the DHCP for your network, look in the network settings for resevations.
    If you can add a reservation, then add the one your phone is already using to see if this elimates the problem, at least on your network.
    If you know how to set up a reservation, you can skip this part.
    First write down the network settings that are on your phone under the blue > dot.  When you change from DHCP to Static, iOS will clear the settings, so write them down.
    Tap on Static and fill in the information you just wrote down for the static address settings.
    Now put the phone in airplane mode or turn off WiFi on your phone.
    Assuming you can add a reservation to your router, you will need to know you phone's MAC address (Settings>About WiFi address) so you can find it in the address pool. 
    Your phone's address in the pool should be the same as what you wrote down already and revoke the address from the pool.
    Now you can make the new reservation and type in the IP address, the MAC address and a description of your phone, typically.
    Save the settings and the router will probably restart the network, so make sure anything already on the network is ready to go offline for a minute or so.
    Take your phone off airplane mode and it should join the network.  If it doesn't, confirm the addresses are the same and make sure the MAC address is correct.
    If your router can't take a reservation, then the only other suggestion I can make is to aquire an Apple router.  Check around ebay to see if you can't get an old AirPort Extreme Base Station (the ones that look like a space ship) and attach it to your nettwork as a subnet.  I just spotted some on ebay for under $10.  Also if your network is secure, just make sure the subnet is also secure. 
    If you're unfamilar with Apple routers, you set them up using software from Apple, so if you have a Windows PC you will need to download the AirPort Utility software http://support.apple.com/kb/DL524 and install it on your PC.
    Beyond that I'm afraid I can't help, sorry.
    Best of luck,
    UG
