  • Toshiba EXCITE Pro - WIFI connection. Authentication failed after update

    Hello.
    Just received this Tablet.
    Everything seemed ok while updating to the latest version (did that first to solve the heat problems).
    After the last update *i lost my WIfi connection. Authentication failed* (didnt change something - was connecting - updating ok 1 minute before the last update).
    After that i started testing ,Wps connection , No security Wifi etc etc.
    *Finally at a random time (and with the initial settings) i got connected*. After i shut down the tablet the same problem occured.
    After doing the same things again i finally got connected and this time it seems to be ok, even after i shut down the tablet.
    However this is frustrating.
    Maybe you have to sort this out?
    I have seen and other people returning this tablet after having this problem.
    It is not a hardware problem since its working ok before the update.
    Of course tried factory reset twice.
    Hope i dont have this problem again, *but i am informing in hope that you fix this in a future update.*

    Toshiba sent me the fix for this. Figured I would use Facebook and they sorted a solution straight away.
    It requires a complete reset. Not the soft reset from within Android.
    I'll post it here as they will check through moderation I guess.
    Thanks for sending a private message Ben. For us to get this resolved for you we would advise to perform a reset from the Android system recovery menu, to do the reset please follow these steps:
    The reset process will delete any data, settings, and applications on your tablet. You must have a backup of any data you wish to keep before proceeding.
    1. Make sure the tablet is off and not in standby.
    2. Hold down the Volume Up and Power buttons simultaneously until the two Android icons appear.
    3. Use the volume buttons to select the white box on the right.
    4. Once selected, press the power button.
    5. Use the volume buttons to select wipe cache partition and then press the power button.
    6. Select Yes and press the power button.
    7. Use the volume buttons to select wipe data/factory reset and then press the power button.
    8. Select Yes and press the power button.
    9. The tablet will now reset.
    If you have any issues after the reset please get back to us as soon as possible!
    Its been working well ever since. I guess the cache clean part might be the main one. You'll have to select the reboot yourself as I did at the end.
    Might be best to use Facebook i'll see if I can find my post as the response was quick and efficient unlike their responses in here. I.e nowt from them so far.
    They needed my name and serial numbers probably to log problems etc.

  • Can't get iCloud to back up on IPhone 5. Have 7.1 GB available. Backup keeps failing while I am plugged in and connected to wifi

    Can't get iCloud to back up on IPhone 5. Have 7.1 GB available. Backup keeps failing while I am plugged in and connected to wifi. It will show backing up now and estimated time 20 plus hours and always ends up failing after a couple hours

    You need at least 50 MB of free space in order to back up to iCloud.  Rather than backing up, have you tried importing the photos to your computer and deleting them from the camera roll as explained here: http://support.apple.com/kb/HT4083?

  • I have been receiving the message ' Cannot get mail. The connection to the server failed' but I am connected to WIFI

    I have been receiving the message ' Cannot get mail. The connection to the server failed' but I am connected to WIFI.  I have also been receiving  'Cannot send mail, an error occurred while delivering this message.

        Hmm, that's odd JeanEB. The error message referts to the connection to your email server not to cellular data or connection to wi-fi. Go to Settings>Mail, Contacts, Calendars> Select your account and type in your password again. If this doesn't resolve it, delete/re-add the email account.

  • My iMac keeps on losing internet connection. Webpages get stuck after a minute or so. If I check the internet connection via diagnostics it seems to work just fine. Others, like the iPad use the same wifi connection and never fail. What can I do?

    Running 10.6.8 on Intel dual core iMac, it keeps on losing internet connection. Webpages get stuck after a minute or so. If I check the internet connection via diagnostics it seems to work just fine. Others, like the iPad use the same wifi connection and never fail. What can I do?

    Greetings,
    I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
    At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
    The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
    I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
    You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
    Good Luck - Cheers,
    M.

  • IPad 3 with iOS 6 fails to connect to WiFi with WPA2 and AES - any solutions available?

    Hello *,
    after upgrading my iPad 3 to iOS 6 it constantly fails to connect to WiFi with WPA2 and AES - hidden or broadcasted SSID - at home and at work because the device does not accept the WPA2 password. This is also the case for my iPhone 4S but both devices did work with WiFi (WPA2 / AES) perfectly with previously installed iOS 5.1.1.
    I tried to downgrade to iOS 5.1.1 but it seems to be no longer possible to downgrade for both iPad 3 and iPhone 4S as the certification and signage window for iOS 5.1.1 maybe has been closed by Apple.
    Does anyone know about a possible solution to connect to WiFi with WPA2 and AES with iPad 3 / iPhone 4S and iOS 6 upgrade?
    Thank you very much for any help and advise.
    Best regards from Germany
    Matthias

    Additional things to try.
    Try this first. 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.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    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
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

    Tried to use iphone connecting to wifi but failed dispite password correct, cable connection ok, and even reset network setting in iphone. Anyone can help?
    Kin Chi

    I get in now with the following procedures taken:
    1. Reset network as suggested in Apple app.
    2. In the wifi connection, instead click in the user name as shown in the screen, I click Others and re-type the user name as appeared before. In the security, instead of none, I click WEP. It will then prompt you to put in password. I then put in password as I know for that user name again.
    Then, it joined the wifi..
    Hope this can help someone who get this problem.

  • PlayBook fails to connect to WiFi

    Hi,was wondering if you could help me,I've had a bb playbook 2yr n love it,my son "borrowed it"4 his holiday n since I've got it back it won't connect to WiFi,so its virtually useless am gutted,I've tried everything I can n no joy,its as if there's something blocking it,it finds it but wont connect can you help please x
    MSohm (Edit note) - Moved message to new thread and edited subject.

    Try turning off the power again, but this time disconnect the power cord and USB cable for 5 minutes.
    Then reconnect the power cord and turn on and check the network settings (in case the IP address has changed - it should not have but check anyway). Then open Network Utility (Applications > Utilities) and select the Ping tab. Enter the IP address of the MX860 and press Ping. You should get a ping response for each packet sent. If you do, then it shows there is a working path between the Mac and the MX. If there is no response, then there is an issue with the wireless connection between the Mac and the MX.

    No, it is not a known issue. It is a known non-issue. Try resetting your IMAP login ID and password. Both the incoming and outgoing. If that fails delete the account reboot the phone, and add it back.

  • Officejet 4630 will not connect to wifi

    Bought this printer a few months ago, set it up, no problems.  Now all of a sudden, it will connect to wifi.  Nothing with wifi has changed.  Printer finds wifi, I enter the password, and it thinks for a while, then says "Connection Failed, Cannot connect to network".  When I print the report, the only thing that fails is in settings "no filtering".  Tells me the solution is to add the mac address but doesn't tell me how to do that.  When I scroll through the settings, it looks like the mac address is there.
    This question was solved.
    View Solution.

    Power off printer and router. Power on router and wait 3 mins. Power on printer and verify it connects to the router. Do you have a valid IP address??

  • Retina macbook pro can't auto connect to wifi after wifi router rebooted

    My macbook pro with retina can’t automatically connect to wifi after the wifi router was rebooted. There is exclamation mark on wifi sign. As I clicked the wifi sign, it shows no Internet connects. However, It is strange there is a tick in front of my wifi name. In order to use wifi, I had to click off wifi, and then click on. The previous version, Macbook pro, has no problem like this. I had deleted all files under wifi library, but still fail. Appreciating for any way to solve it!

  • I'm travelling and trying to back up my new iPhone to iCloud. I have sufficient storage, am connected to wifi and it's plugged into a power source and yet it doesn't seem to work. Can anyone suggest what I'm doing wrong?

    I'm travelling and trying to back up my new iPhone to iCloud. I have sufficient storage, am connected to wifi and it's plugged into a power source and yet it doesn't seem to work at all. I'm currently in India. Could that be the cause or can anyone suggest any reason why this wouldn't work?

    "gets stuck" - are there any error messages?
    If you get the error "Backup not successful" and you've tried deleting the last backup and trying to back up manually without luck, try the following test:   Go to...
    Settings>iCloud>Storage & Backup>manage Storage, tap your device name in the Backups section, then look under Backup options.  Turn off all apps from backup and then do a manual backup.  If that doesn't work, then this post will not help.  If the backup works, then go back to the app list and turn some on and try another backup.  If successful, keep repeating these steps.  If it fails at some point, then try to zero in on the one app that seems to make the backup fail.  (I had this problem and found one app failing, probably due to a corrupt data file.)
    This process will take time, but if a backup works with no app data being used but clearly fails with the original settings, then somewhere in the mix of apps is a "bad" one.

    What I know is that the phone worked perfectly fine until I upgraded the software. I've tried resetting the network settings to no avail. I've shut the phone off, put it in a ziplock baggie and then into the freezer for 15 minutes. This made the wifi work temporarily but then it goes back to being grayed out. The wifi does not work at other wifi sites away from my home as well. Seems like an apple issue to me and would appreciate someone coming up with a fix, apparently I'm not the only one having this problem. Thanks for replying to my query, any ideas?
    It's likely a hardware issue.  The iOS will not directly cause this issue.
    Use this article first:
    iOS: Wi-Fi settings grayed out or dim - http://support.apple.com/en-us/TS1559
    If that fails to resolve it, then try setting it up as new and testing again.
    How to erase your iOS device and then set it up as a new device or restore it from backups - http://support.apple.com/en-us/HT4137
    If the issue remains even after set up as new, it's a hardware problem, not a software problem.  You'll need to contact Apple for you hardware service options.  If within warranty it should be free.  If not, expect to pay $149 USD + tax if it's an iPhone 4, $199 USD + tax if it's an iPhone 4S.

  • Cannot connect to wifi, cannot change network settings [SOLVED]

    Asus EeePC.
    lspci -k shows
    Broadcom Corporation BCM4313 adapter is the hardware, and appears to be working. Kernel driver in use is bcma-pci-bridge
    In Gnome, Wi-Fi status shows "not connected"
    "Select Network" shows a list of available APs, I click on ours which is set up as WPA2 PSK. Click Connect. Nothing happens. At all, no dialog for password, no attempt to connect seems to be processed by the computer. This happens with open networks as well (coffee shop or whatever). Click connect but nothing further happens.
    From the applet I can't even seem to be able to "Turn off" the WiFi at all.
    From within Wi-Fi settings in the applet, I can see a list of available access points but clicking on them does nothing. There is no available way for any user input, although I can click the toggle to turn off Wi-Fi from within there.
    I can't forget networks in my history here either: click "History" and I can see a long list of previous networks. I can check box for them all and say "forget" but then they're back when I open the history again.
    So it seems like my NetworkManager is just simply not working. Can't change the current state of "not connected" to anything at all.
    When I attempt to connect using Wifi-menu I get:
    Successfully initialized wpa_supplicant
    >WPA Authentication/Association Failed {FAIL}
    When I attempt to connect to any network. It never asks for password.
    Gnome-Keyring is installed.
    Netctl is NOT installed.
    NetworkManager is installed and running according to systemctl
    I've been running this Arch install on this machine for two years. This is not a new install problem. No hardware can be changed on this machine, so it's not hardware related (unless the wireless device itself crapped out).
    Possibly related, I cannot shutdown the machine from within Gnome. I have to "sudo shutdown -h now" from a terminal. Seems to hibernate/sleep properly when the lid is closed though.
    All of the results of searching on this indicate usually the problem is multiple network config softwares installed at the same time, like netctl and networkmanager together. Or not having a keyring manager installed That is not the case here unless it is one of those that is broken, but they don't seem to be.
    I have no access to any wired connection at the moment at all, so I can't download anything to this computer at the moment. There's gotta be a way to get wifi working again, as it was just working last week. Haven't even done a pacman upgrade between when it last worked and when it stopped working.

    I did mention the hardware is a Broadcom BCM4313
    It may have been an issue with the Broadcom not working with iw. Not sure, as I haven't really changed things on this machine much (it's my wife's and I regularly update it but don't fuss with it much beyond "get it to work"). Like I said, the install is 2 years old, so compatibility may have even changed since I initially set it up.
    I'm currently at work and without direct access to the computer in question. So I'll get those results later tonight.
