Can not connect to wifi-network

I have a iphone 4 that I managed to lose in the toilet. it is relatively in good condition,but can not connect to wi-fi networks. seems as if it is unable to receive signals. is there anything I can do to fix it?
and I have no dial tone when I call. what can I do?

Apple has an out of warranty replacement program for phone's like yours, cost in the US is $199. That would be your best course of action.

    When you say it "can not scan any wifi network" do you mean it is not detecting Wi-Fi networks?
    Is Wi-Fi turned on in Settings > General > Wi-Fi?
    Have you tried Settings > General > Reset > Reset Network Settings?
    Is it just the home network that the device will not connect to? or any network?

  • Hello my iphone 3g can not connect to home network via wifi

    Hello to all, with my iphone 3g can not connect to home network via wifi. This only happens if I apply protection to the network. Unprotected my Iphone connects fine. Obviously the password to write error-free. I can not figure out what depends on this factor, however, another iphone connects fine. Help me please.

    I have a similar,but slightly different problem. My iphone 4 recgonizes my home wifi and shows it under Settings, but will not access it, no signal shown, just 3G.  It will access other wifi signals.  My wife's iphone works fine, as does an ipad and macbook.  This is new for my iphone, about 2-3 days.
    Help!  I reset network settings and rebooted the router (Apple), no avail

  • IMAC can not see any wifi networks at all?

    IMAC can not find any wifi network at all. A few days ago the Imac suddenly had no wifi and on turning the WIFI on and off it became apparent that when it scans for wifi it can see no wifi networks at all. I have several other computers and they all see the wifi networks fine. I assume it is a hardware issue but the hardware test I preformed comes up with no errors. Anyone got any ideas?

  • Can't connect to wifi network after iOS update

    Can't connect to wifi network after iOS update.

    This does not work in my case.
    Situation: we have wifi at home using WPA encryption.
    The iPod Touch 8GB connected seamless to this network and anything was ok. After some days i could no longer connect, the iPod told me "connection to network 'networkname here' failed". Deleting the network and reenter the (correct) passphrase was no help, but changing the SSID on the router was helpful: the iPod could connect again ... for several days.
    Now things stopped working again. Resetting network settings did not help either.
    The iPod can see the network, is asking me for the passphrase and after several seconds telling me: can't connect. On the router log i don't even see a dhcp request, but other laptops work fine with the same wifi network.
    That's a mess, i cannot and will not change the SSID every some days just to get the iPod working again.

  • TS1398 I can not find my wifi network on my ipad. My iphone conected fine.

    I can not find my wifi network on my ipad, My iphone connects fine. I tryed restarting the ipad and router. Please help

    Some things to try first:
    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.

  • With new OS6 I can't connect to wifi network with my iPhone

    Ever since I upgraded to the new iOS6, my phone will no longer connect to my wifi networks. It only works on 3G. Tried to reset networks and various other things to no avail. Not happy ...

    you will have to use the old fashioned way, like if you lost a wallet or purse.
    - Change the passwords for all accounts used on the iPod and report to police
    - There is no way to prevent someone from restoring the iPod (it erases it) using it.
    - Apple will do nothing without a court order

    If these don't work you probably have a hardware problem. Visit an Apple store for an evaluation or contact Apple Support.

  • I can not connect to wifi using iphone 4s

  • I can't connect to wifi network and bluetooth on iPhone 4S.  Need help.  Have already rebooted everything and reset network setting

    I can't connect to wifi network and bluetooth on iPhone 4S.  Need help.  Have already rebooted everything and reset network setting

    I have the same problem; tried a phone restore, both restoring data and setting up as new phone with factory settings, reset all settings, re-boot, remove apostrophe, put in fridge, you name it!
    I think there's quite a few iphone 4s users with the same problem!
    I called Apple they said it's a hardware problem, but it has worked for nearly two years; they say go to the Apple store and they can provide a replacement phone for approx. £150!
    I've been into the O2 shop where I bought it and they knew the problem exactly; said they had sent a few phones off for repair and had them back awith a report they cannot fix it because it's a software problem!
    An assistant in the shop had the same issues; logic says it's a software problem and hopefully Apple will fix it with a patch but at the moment they seem to be avoiding everyones comments!
    If anyone else has any ideas these would be appreciated?

  • My iPhone 5S can't find and does not connect to wifi networks. Occasionally will connect for a few minutes but then drops  and won't connect or find wifi network again

    A
    Any ideas why my iPhone 5s won't connect to wifi networks. Sometimes does find the networks and others finds them, connects for a few then drops

    You do not say if you tried any diagnostic steps yet. The first thing to do is to do a reset or reboot of the phone. This does not erase anything on the phone and is akin to completely shutting the phone off and then a fresh reboot.
    First close all apps - double click on the home button and whisk away the apps toward the top of the phone to close the app.
    Now press the home button once to go back to the regular menu screen
    No press and hold the home button and the sleep/wake button the the top right side together for 10 seconds. The phone will turn off and reboot.
    See if that fixes it.

  • IPod Touch will not connect to WiFi network

    Hi,
    I am getting errors connecting to WiFi networks with my iPod Touch. This had affected a Touch I got a couple months ago. Initially, the WiFi worked perfectly on my WEP network and several others. Then, one day, I couldn't get any WiFi. After standard troubleshooting steps (forget network & re-enter, reset network settings, restart, restore iPod, etc.), it still wouldn't work. I returned the iPod and bought another. At first it also worked perfectly on any WiFi network I joined.
    But now I'm affected by the same issue. This time, I went to the router settings and saw that the router (a Linksys) had assigned the iPod Touch an IP address. Yet, in the settings pane on th iPod Touch, the iPod had no IP address. I just ahead and reset all network settings, forget the network, reset the update and still nothing. And this was recently after updating to 1.1.2 firmware.
    Given that this has now happened to iPod Touches, I'm concerned that it may be an issue that is affecting others. Any suggestions? The error I get in Safari is "Safari can't open the page because it can't find the server."

    same problem!it connects to the linksys(not always,but miracles happen),and it can't load any page. it's really anoyingi. actually remember that the first day i bought it could've connect to linksys,but then my dad just helped me to acces our network and i didn'try to use it. but when i was in neighbourhood and wanted to open safari, it found me a link sys,but couldn't load anything. like nothing,even thou the signal was pretty strong...and i tried to do something like this in different places and buildings,the only place where i could actually connect is home with my network,that's it!
    i don't want to return my ipod,but it really drives me to it..=/
    is there anything that i can do?
    tnks.
