Problem connect to a wifi network PEAP

Hi
Since OS 2.1 on my playbook, I cannot connect to my PEAP with MSCHAPV2.
It was working on OS 2.0.
I'm now using OS 2.1.0.1314 and the problem is still here.
The playbook connect to the wifi, when I open a browser I must login with my user name, but this part doesn't work.
I get a error "Network error'.
When we use the appworld, a windows popup a little bit different that the other and it work when we use the same user and password.
I can get you some screen shot if it will help you.
Thanks

Hi
I try it and the problem is still here.
When I go to browser I have this screen
https://docs.google.com/open?id=0B7HzFnxiPS2PNlNxW​EV2bk8tMUk
Then this error:
https://docs.google.com/open?id=0B7HzFnxiPS2POERWX​zRjWENRaXc
When I go to appworld I have this screen.

And it works

  • When iBooks has a problem connecting to a wifi network, it hangs and the page goes blank

    i use the books I have in iBooks as study aids, a lot. I find that when I am in the vicinity of a new or busy wifi network that the page or bookshelf just goes blank, I have to switch wifi off and restart the app, then it works again. It is most annoying though.

    Reboot router, make sure it's up to date. If on wifi try ethernet. Make sure DNS is set to automatic (settings - general - network).

  • 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!

  • Touch screen stopped working. Is there anyway to force a full backup of the iPhone without typing in my passcode lock or is there anyway to force it to connect to a WiFi network so the phone can backup to iCloud??

    Hello all, I could use some help with my iPhone 4, I hope this is the best place to ask!
    The Problem:
    I want to do a full backup of my iphone to either itunes or to icloud. Unfortunately the iphone got wet and isn’t working properly. The phone turns on and still works, but the touch screen no longer works. I have a passcode lock on the phone so iTunes will not allow me to backup it up until I type in the passcode (which I cannot physically do). WiFi had been turned off before it got wet so it won’t connect to any known WiFi networks either to backup automatically to iCloud.
    What happened:
    I had been travelling for 6 months and went tubing on a river with my iphone in a dry bag. Unfortunately the dry bag failed and filled with water ruining my iphone.
    What I’d like to do:
    It’s an old phone and I was planning on buying a new iPhone anyway. I would love to do a full backup to either iCloud or to my computer so when I get a new iPhone I don’t lose anything. I’ve already connected it to my PC and downloaded all the photos and videos off the phone so at least I haven’t lost that, but I would like to be able to recover all the text messages, WhatsApp messages and notes I had created during my 6 months of travel.
    The last time it was backed up to my pc or to icloud was in April, so there are 6 months worth of very meaningful data I would love to keep to remind me of my travels!
    Is there anyway to force a full backup of the iPhone without typing in my passcode lock or is there anyway to force it to connect to a WiFi network so the phone can backup to iCloud??
    iTunes recognizes the phone just now and I tried upgrading the phone to iOS7 in the hopes that it would first backup and then upgrade. Unfortunately all that happened is the phone upgraded to iOS7, but it didn’t backup to iTunes. Now the phone is stuck at the iOS7 welcome screen and I can’t do anything else with it.
    Any ideas or tips would be welcome!
    NOTE: This is NOT a jailbroken iPhone.

    If there is no other way around this, is there anyway to completely wipe the phone then??
    The Apple store agreed to give me a new iPhone 4 as a warranty replacement for $150 (I travel a lot and I have a factory unlocked phone, so this is still worth it for me).  But before I trade it in, I would like to make sure all my data is backed up on the device first.
    When I try and restore the phone now on iTunes, it says I have to turn off Find My iPhone on the phone first before I can restore it.  Now since I can't use the screen I can't really do that.
    So how do I completely wipe the iPhone???
    Thanks!

  • 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.

  • HT1695 I can't connect to my wifi network not even when it has no security on I get "unable to connect to network "netgear" anyone have this issue and maybe know how to fix it?

    Hi

    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router.

  • After updating my iPhone 5 to iOS 8.1 it will not connect to the wifi network at work even though it recognizes it. It however still automatically connects to the network at home. I have restared the phone and toggled the router, still no connection

    After updating my iPhone 5 to iOS 8.1 it will not connect to the wifi network at work even though it recognizes it. It however still automatically connects to the network at home (this is the network I used to update the phone). My iPad however does not seem to have any problem connecting. I have restared the phone, toggled the router, re-entered the network password but there's still no connection.

    When your device is trying to connect to the work Wi-Fi network, go to Settings > Wi-Fi > then tap on the name of the Netowrk that she is having trouble with. Then tap on forget this network. Let the device attempt to connect again and make absolutely sure she is trying to connect to the work network and not a nearby network, then make absolutely sure the password is entered correctly.

  • I can't connect to the router in my home.  Things were working fine as usual - I attended school and connected to their WiFi network as usual.  When I returned home I could not connect to my own home router.  The Ipad seeks the network but nothing happens

    I can't connect to the router in my home.  The Ipad seeks the network but nothing happens.  I went to school and connected to their WiFi network as usual with no problems.  When I returned home I could not connect to my home router.  The Ipad seeks the router number but nothing happens.  I rebooted the Ipad a few times in the school.  The numbers identifying the router, etc. on my Ipad no longer appear there. 
    TThe Ipad guide says to connect to the WiFi use setup but I can't find the setup program in the Ipad.
    I reset the network settings to the factory defaults but this doesn't fix the problem.
    What can I do to reconnect to my home router?

    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)

        •    Tap on Wi-Fi

  • How to authenticate using PEAPv1 (EAP-GTC) to connect to a wifi network in iPad 3?

    The iPad in Business deployment senario guide says that we can connect to a wifi network using the PEAPv1 (EAP-GTC).
    But when we try to connect it, there is no option to choose that authenticaion method.
    Also, when we try to create a profile using iPone Configuration Utility, there is just PEAP available (by default PEAPv0 (EAP-MS-CHAP v2)).
    It is very important for me as my organisation allows only PEAPv1 authentication and I'm not able to connect to its wifi network.
    Thanking all of in anticipation.

  • Mac NOT automatically connecting to preferred wifi network

    Hi,
    I am facing a problem with OS X 10.9.1 (Mavericks) wifi connection.
    I use a Time Capsule as a base station and 13" Macbook Air (2012). The base station is connected to the internet through a PPOE connection.
    Here are the details.
    Since upgrading to OS X 10.9.1, my Mac automatically connects to preferred wifi network ONLY WHEN the wifi is available at start up or when the Mac wakes up from sleep, but NOT OTHERWISE. 
    Before the upgrade, the Mac automatically connected to the preferred wifi network not just at start up, but whenever the wifi became available.
    In other words, after the upgrade, if I boot up the Time Capsule base station and the Mac simultaneously, the Mac scans for the base station wifi network (this is configured as the top preferred wifi network) at start up, but since the base staion is still booting up, the Mac doesn't find the wifi. 
    But once the base station has booted up and wifi is available, the Mac no longer bothers to join it.  At this point, the Mac is also not able to do Time Machine backups to the Time Capsule because it is not able to locate the Time capsule disk over the wifi.
    This situation remains (i.e., the Mac being not connected to the wifi) unless I do ONE of the following:
    1. I manually select the preferred wifi network using the wifi icon at the top of the screen;  OR
    2. I put the Mac to sleep (by closing the cover) and then wake it up.  On wake up, it connects automatically to the preferred wifi network; OR
    3. I turn of the wifi (using the wifi icon on the top) and turn it back on, at which point, the Mac automatically connects to the preferred wifi network.
    I have tried everything possible including contacting Apple support, but so far the issue is unresolved. 
    Appreciate any help you can provide.
    Prem

    I have had wireless problems intermittently for a year, and seriously for 6 weeks. Apple denied the issue and was no help in spite of many tens of thousands of people on their own discussions complaining. I found a post suggesting a couple of things which fixed the problem. I don't know if both are necessary, but the first by itself does not solve the problem.
    Lock the channel of your router to channel 1, apparently Apple and 802.11n don't play well together on higher channels. When this becomes a standard this will be resolved I hope.
    Open your network preferences, select 'airport' and advanced. Delete unused networks. Select your network.
    Open TCP/IP and write down all the settings, configure iPv4 manually. Enter the settings manually. Turn off IpV6.
    Open DNS and write down your DNS server. Delete it and re-enter it manually.
    This has worked on 2 macbooks and an iMac for the last 3 weeks with no network drops.

  • HT4623 i just updated my ipad to ios 8 but i cant connect to wifi network..its says my password is incorrect although i know my password is correct as successfully updated 2 iphones and connected to same wifi network

    i just updated my ipad to ios 8 but i cant connect to wifi network..its says my password is incorrect although i know my password is correct as successfully updated 2 iphones and connected to same wifi network

    I had the same problem. I reset my network settings as iOS 8 on my iPad 3 seemed a bit slow. When I tried to reconnect to the wifi the correct password was not accepted immediately.
    after retrying several times it did manage to join the network. The only observation I had was that I had a weak signal and an iPhone next to me at the time.
    make sure you are close to the wifi signal away from any other wifi devices.

  • Cannot connect to my WIFI network since updating to IOS 7.0

    Since updating to IOS 7.0, I have been unable to connect to my (or any) wifi network.
    I have tried every suggestion / help from the forums / web searching.
    I have tried different wifi connections (all the same - unable to connect to network).
    Waited for the 7.0.3 to see if this has fixed the problem, but no..
    I'm extremely frustrated and would like Apple to help.. I'm not the only person with this problem - and I haven't seen a single response from apple regarding this.
    Since I am now out of the 1 year warranty - I will be pursuing this through the 'sale of goods' act in the UK if I don't receive a satisfactory response - I expect my device to last longer than a couple of years and consider the ipad broken as a result of the update...
    Have been very happy with my apple devices up to this point, but loosing patience now!

    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.

    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.
