Unable to connect to wifi network

I put my (2 day old) iPT to sleep last night in the middle of watching some Netflix streaming video. When I woke it up this morning, the Netflix app tried to resume play and failed. The iPT started asking for a network password. I made a few careful attempts to enter it (it is one of those 64 random character things, and my iPT typing skills are nascent) and it failed to connect. Finally iPT began saying 'unable to connect' and stopped asking for a password. I checked the router, connected with my laptop, no problems there. Perhaps the router has some lockout after failed login attempts, but if so I could not discover the setting in order to reset it.
Finally, I reset the iPT network settings, and was able to connect and enter the password successfully.
My question is this: why did this happen, and can I be at all confident it won't happen again?
I've never had a similar problem with other wifi devices I've used with this router since setting it up over a year ago, so to my mind it is obvious there is a problem with the iPT wifi hardware or software. Needless to say, it is a pain to enter the wifi key once, let alone every few days.

Your post indicates that you are using WEP security. Do as Apple suggests and move to WPA or WPA2 security. WEP is obsolete and can be cracked in seconds with widely available software.

  • Unable to connect to WiFi Network Following Upgrade to OS X 10.9.1

    I wanted to post thus to ask if anyone is experiencing issues with WiFi following upgrading to 10.9.1?
    On Monday I upgraded to 10.9.1 from 10.9.  Immediately following the install and reboot, plus for the next four hours - all was well.  I have booted up the MacBook this evening and now I am unable to connect.  The following is being reported in Console;
    time airportd: _doAutoJoin: Already associated to "network name". Bailing on auto-join
    time kernel: Airport: Link a Down on en1. Reason 8 (Disassociated because station is leaving)
    I have connected to the network many times previously without an issue.  My iPad, iPod and my iPhone connects fine.  Also a couple of a Windows 7 SP1 machines connect fine.
    I have saved out the airport plits file, creating new settings from scratch - didn't work.  Rebooted, etc - didn't work.  Put the initial plist file back - still doesn't work.  Currently unable to reboot the router.
    Is this an issue with 10.9.1?

    Got it working...  Needed to reconfigure the Network settings and reboot the router.

  • MacBook (10.4.11) is unable to connect to wifi networks

    After updating with 10.4.11 (and the associated 2008-01 Airport update) a few months ago, my Intel MacBook has been unable to connect to my WPA2 network.
    It will see my network name in the Airport drop-down menu, but fail to actually connect. The icon appears as if the notebook is rapidly connecting and disconnecting -- switching from five bars of signal to none and back again every few seconds. During this time, my MacBook never reports getting a connection, and all other devices on the network experience severe interference. I am able to connect to most, but not all, unsecured networks.
    System Profiler reports my wireless card as AirPort Extreme (0x168C, 0x86), Firmware Version: 1.3.5 .
    My router is a D-Link DGL-4300 with the most recent firmware. I am running an 802.11g network at 2.437ghz.
    I've tried the following already, unfortunately without success:
    . Switching to WPA from WPA2
    . Removing all the preferred networks from my System Preferences and adding them back in again.
    . Removing all the network info in my keychain and reconnecting to the network from scratch
    . Switching the router to channel 11 (away from 6)
    . Turning Interference Robustness on and off
    . Manually specifying IP and DNS in my network settings, rather than DHCP
    . Removing all other wireless devices from the network
    Looking elsewhere on the net I find that a few other people seem to have this problem, and so far the only solutions I've seen are "roll back to 10.4.9" and "disable security on your home network," both of which are obviously untenable for security reasons.
    The one (and only) WPA-secured router I am able to connect to is the Airport at my local Genius Bar, so they're unable to help me.
    Has anyone else seen this, or have any ideas?
    Thanks.

    Well, I downloaded Pacifist and the 10.4.11 Combo Update. Pacifist verified the AppleAirPort and AppleAirPort2 .kexts on my drive as matching the ones in the package, but I forcibly reinstalled them anyway and rebooted. Still no luck -- now the network is back to the four-bars-no-bars death loop without even popping up the error dialog.
    Luckily however Pacifist turned out to be the solution to the problem. A Google search on "Apple broke Airport" eventually led me to this thread with detailed instructions on rolling back to the previous version of the Airport driver, before the 2008-01 update: http://www.tuaw.com/2008/03/28/airport-extreme-update-2008-001-for-tiger/#c11509 504
    I'll paraphrase it here for anyone else who has this problem:
    Download the Airport Extreme client software version 2007-004
    from http://tinyurl.com/yw3dnu.
    Download and install Pacifist from www.charlessoft.com.
    Delete /system/library/extensions/io80211family.kext
    In Pacifist, open AirportExtremeUpdate2007004.dmg
    and expand the sub folders until you can see the io80211family.kext
    extract and direct it to extract the file to the
    /system/library/extensions/ folder
    restart
    So now my Airport works again, though without whatever security they put in with 2008-01, I guess.
    I suppose I'll have to embargo future OS updates until this gets straightened out, or else re-rollback the io80211family.kext after each one. I sure would like to talk to whoever wrote this update at Apple!
    Thanks for your time, BD.

  • Why can I connect to my home network with my iPhone 5 in one room, but when I move to another it is 'unable to connect to the network'

    At home, I can connect my iPhone 5 to my home wifi network with no problems, as long as I stay downstairs.
    As soon as I go upstairs my phone disconnects from the network. I can still see the home network it in the available network lists (with full signal strength), but when I try to reconnect I get an 'unable to connect to the network message'
    If I move back downstairs it reconnects
    This has only started happening in the past week or so
    I've tried to forget and rejoin the network, but this doesn't work
    I reset my network settings on the phone. This worked for a couple of hours and I could connect to the wifi upstairs, but now it won't connect again.
    Does anyone have any ideas what is causing this?

    Sounds like your wi-fi signal strength has degraded.  Try rebooting your wi-fi router, or get it serviced.
    Do you have similar issues with any other wi-fi routers?

  • Cannot connect to wifi network

    I've seen other folks discussing issues with Wifi connectivity in Mavericks, but can't find a specific answer to my problem - hopefully somebody can chime in.
    I recently purchased a (refurbished) 15" retina Macbook Pro, Mid-2012 model.  It came with Mountain Lion installed, but I immediately updated to Mavericks. My home wifi is secured with WPA2 - Personal, and I was initially able to connect even after the Mavericks update.  However, my wifi speeds were terribly slow, so I went and changed the router settings in the hopes of speeding things up (using a separate computer connected directly to the router).
    As soon as I made the changes, my Macbook was unable to connect to the network.  The name of my network still appeared in the list of available networks, but as soon as I selected it I recieved a message saying "Wifi network "(network name)" could not be joined." It would not even give me a prompt to enter my password, just an option to run diagnostics, which provided no help whatsoever.
    I tried reverting the router to the previous settings, but the issue persists. I am able to connect to other nearby WPA2 secured networks (or at least get a prompt to enter a password), but not the one I was using previously. I am able to connect to my network if I disable the security, but as I live in a fairly large apartment building, that's not a permanent solution. Anybody have any insight into what might be causing this issue?

    I have an android phone as well and i found an app called "wifi tether" version 3.1-beta. They listed as web address in the about section on the app http://android-wifi-tether.googlecode.com i am not sure if the address is good but it might give you some insight. The app works for me on my k1. But you are right ad-hoc support would be great.

  • I am unable to connect to wifi on my Iphone 5

    I have rest my phone and everything and I am still unable to connect to wifi. I entered my passcode at my apartment and it didn't work and now I am at my university and I have entered my secure passcode and it is still not working. Can you please help me with this?

    I was experiencing the same problem. Tried numerous fixes. What finally worked was I went into Settings>General>About; recorded my Wi-Fi Address, and manually entered it into my router as an recognized/allowed device.  Selected by network, entered the password on the iPhone, and Bingo! I was in!!
    Good Luck

  • IPhone 5 unable to connect to WiFi

    iPhone 5 unable to connect to WiFi - signal good, iPad connects fine but iPhone comes up with error message "Unable to join the network". I've tried reboot. Any ideas?
    Thanks

    I called Apple and explained the problem.  After I explained the wifi connection problems, they said it was a hardware issue and sent me to my local Apple store and exchanged mine for a new iPhone.  I backed it up prior to getting the new phone and it was easily restored. 

  • Unable to connect Wi-Fi network after ISO 6 update

    unable to connect Wi-Fi network after ISO 6 update. I'm not impressed.

    I updated to ISO 6 on my Daughters Iphone 4S, my Iphone 4, and I have now received my new Iphone 5 yesterday and now all 3 of them have wi-fi issues. I know its not my wi-fi because My Daughters Ipad 2 and my Wife's Iphone 4 is still on 5.11 and the wi-fi works fine. I cant understand why apple have not been saying what's going on and when they will fix it. I have tried everyone's suggestions on this forum and the Internet. Still no luck.

  • My iPhone 4s connects to wifi networks, but internet own't work with password protected networks

    Hello,
    I have an iPhone 4S.  I have been having issues with my wifi.  It works for several months, but one day for no reason I have been able to determine, the wifi stopped working.  It has been many weeks since it has worked.  I have tried several networks (home, work, relative's houses, etc...)
    After visiting the Apple Genius Bar, I was told it was probably a software issue the wifi worked fine in the apple store on a unprotected network which showed that the wifi was able to function. It was recommended that I backup and then to a full reset to factory settings.
    I did the backup and reset.  It has had no effect on my ability to use internet to secured networks.
    I also updated the iOS to the most recent update ( 6.0.1) to see if that would help, but it didn't.
    To summarize:
    -iPhone connects to wifi networks
    -Unable to use internet (or other data functions) while connected to a password protected wifi...but able to do so on unprotected networks.
    -Already tried resetting network settings.
    -Already tried resetting to factory settings.
    -Already tried updating iOS.
    Thanks

    Might be a wifi router issue.  Try power cycling the router and/or updating it's firmware.  You might also try temporarily removing any security features until you get it sorted out.  If still an issue, it might be wifi on the iPhone itself... there have been many reports of wifi problems with iOS6.  Have you restored as new, i.e. without your backup?  You could also Google for ways to downgrade back to iOS5.
    Regarding the Chipotle issue, go for the bowl instead of the burrito.

  • TS1398 after updating the OS unable to connect to WIFI

    after updating the OS to 5.1.1.1 I'm unable to connect to Wifi, while the Wifi is working perfectly for my Iphone

    Look at iOS Troubleshooting Wi-Fi networks and connections  http://support.apple.com/kb/TS1398

    iOS: Recommended settings for Wi-Fi routers and access points  http://support.apple.com/kb/HT4199
    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) 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. 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.
