Internet sharing suddenly stopped working - please help!

I have been sharing my internet for weeks from my computer but this morning it suddenly stopped working. I've tried changing the password, changing the channel number, and changing the Network name to a simple one, but it is all not working Apparently the authentication server is not responding? How can I fix that?

I'm having the same problem. I had internet sharing set up on my iMac from Ethernet via AirPort, and received quite well on my MacBook and iPod Touch, and then one day, it just stopped working. I'm assuming that some update or other caused this problem, but I have no idea which (I mostly use the internet on my desktop machine, so it may have been several days before I noticed the problem). I've tried with-and-without a password, and also tried sharing from my MacBook to the iMac and iPod Touch, and I can't get any bandwidth (I can connect to the 802.11 network that I create, but I can't get any internet through it).

  • WRT150N router has suddenly stopped working - please help :)

    I really don' know much about how routers work, so I am hoping you all can help me.  I have a home PC and an HP notebook.  We have a cable modem and a linksys wrt150N wireless router in order to use the laptop around the house.  It was working fine up until 2 days ago, when it suddenly just stopped working.  Nothing has changed.  I've tried unplugging, rebooting, resetting the little button on the back of the router.  I've tried clearing and refreshing the IP address.  The wireless and the security lights aren't lit up anymore.  I have tried to repair but I get the errors can't acquire a network address, and can't renew the IP address.  I've tried reinstalling the cd that came with the router.  I get router not found.  Please make sure the router is properly connected.  I don't know what to do anymore.  I can't get to the router set up because I can't use the internet without bypassing the router and connecting directly from modem to computer.  Is there any way I can fix this or is this router toast?  We've only had it for 2 years.  I am running XP on the PC, and Vista on the laptop.
    If anyone has any idea what is wrong, please please let me know.  I have school work to do on the laptop and really need my wireless connection back.
    Thanks so much.

    If you are unable to configure your router using the setup disk, then you can configure all the settings on your router manually.

  • My WRT54G suddenly stopped working please help.

    Hi, i recently configured the security of the router, and then when i pressed the auto connect on the router it can no longer send a wireless signal... i tried to press the RESET button on the back, it should return it to the factory setting right? but when i connected it it wont give me good ip addresses it says limited or no connectivity, even if i manual set the ip. then try to access the home page it would not work.
    i have some ideas how to fix this but i dont know if it is possible or not. :
    1.) reset the router from a computer without accessing the page.
    2.) go to a service center (if there is an available in the philippines...)
    3.) overriding the firmware without accessing the page
    please help, or else i would need to spend another 40-50$ for a new router T_T
    i also tried to download the easylink firmware, or the easlink connect
    but i get a 550 error when accessing the page, the online chat is no help either, they say i am on first queue but no one is answering :/

    Hard reset your router for a minute...
    Press and hold the reset button for 1 minute...Release the reset button...Unplug the power cable from your router, wait for 1 minute and re-connect the power cable...Also make sure that your computer is set to obtain IP automatically, disable any firewalls, security softwares on the computer before trying to access the setup page...Now check if you can access your router set-up...
    Click Start >> All Programs >> Accessories >> Command Prompt...A black box will appear(Command Prompt)...In the Command Prompt window type ipconfig and press 'Enter'...Look for Ethernet Adapter Local Area Connection IP Address , Subnet Mask and Default Gateway...IP Address should be 192.168.1.x, Subnet Mask : 255.255.255.0, Default Gateway : 192.168.1.1...
    If you get the above mentioned ip address and gateway then you should be able to re-configure your router...If you get an IP Address of 169.254, then reset the router again...If still you don't get the above mentione ip address and gateway then  you should give a static ip address on the computer...
    Click on the Start button >>> Settings >>> Control Panel >>>Network Connections- Right click on the icon for Local area connection and go to properties- On the 'General' tab select 'Internet Protocol TCP/IP' and click on the Properties button- Select 'Use the following IP address'- Provide IP Address - 192.168.1.5, Subnet Mask - 255.255.255.0, Default Gateway - 192.168.1.1...Click on Ok button to Save and Click on "Close" on main Properties window...Now try to ping the Default Gateway, type ping 192.168.1.1 and press enter, see if you get 4 replies...If it does not then try to diable and security softwares/firewalls on your computer and try to ping it again, you should get 4 replies...
    If you get the set-up page then you can configure your router...

  • Brand new ipod touch suddenly stopped working. please help!

    I was messing around on my brand new ipod touch and it suddenly crashed. it flashed a static-y black and now the screen is bluish white and won't change. I tried holding both the home button and the black button on top of the ipod and neither helped. I even connected it back to my mac book but nothing happened. please help! i've only had it for two days!

    That sounds like a mechanical problem.  You might want to insert and remove the headphone plug several times and see if it fixed the issue.  If it does not, call Apple.  800-275-2273 in the U.S.A. and I think Canada.

  • Ipod apps suddenly stop working, please help very fustrating!

    I got a new Ipod Touch and sometimes the apps I've downloaded work fine but then some of the apps, after I tap on them, will load for a few seconds and show the splash screen but then will stop working and I'll end up back on the home page, and I have to re-install them from the app store so they will work again, Why does this happen? thx!
    (Ipod 2g) (latest firmware)

    There is a thread I think similar to this
    http://discussions.apple.com/thread.jspa?threadID=1735940&tstart=30
    I had something similar happen. I ended up deleting the app and then downloading them from my computer. I have also heard that if you restart your ipod before running the app for the first time that may work. Apple though is aware of the issue.

  • Java in suddenly stopped working. Help?

    Java in suddenly stopped working. Get "inactive plugin". Things were fine yesterday. Checked Java preference and everthing looks fine. Running os 10.6.8. Does anyone have a fix?

    The recently released Java 7 Update 11 has been blocked by Apple through its XProtect anti-malware feature in OS X.
    Oracle issued the latest update to Java earlier this month to fix a serious zero-day security flaw. The threat was so serious that the U.S. Department of Homeland Security had recommended that all Java 7 users disable or uninstall the software until a patch was issued.
    Apple took action on its own and quietly disabled the plugin through its OS X anti-malware system. And as noted by MacGeneration on Thursday, Apple has again updated its OS X XProtect list, this time to block Java 7 Update 11.
    Because Oracle has yet to issue a newer version of Java that addresses any outstanding issues, Mac users are prevented from running Java on their system.
    Over the last few years, Apple has moved to gradually remove Java from OS X. The Mac maker dropped the Java runtime from the default installation for OS X 10.7 Lion when the operating system update launched in 2010. Java vulnerabilities have been a common exploit used by malicious hackers looking to exploit the OS X platform.
    Most notably, the "Flashback" trojan that spread last year was said to have infected as many as 600,000 Macs worldwide at its peak. Apple addressed the issue by releasing a removal tool specifically tailored for the malware, and also disabled the Java runtime in its Safari web browser starting with version 5.1.7.
    Javascript should not be disabled (it has nothing to do with Java).

  • Internet sharing has stopped working after 10.8.2 upgrade

    Hi.  So, for the past year, I've been receiving WiFi internet on my iMac, and sharing it via ethernet and sometimes FW800.  Lately, mostly just ethernet.  As of 10.8.2, this has stopped functioning.  I have heard many rumors about internet sharing issues in the update, but it seems I am in the extreme minority in terms of sharing internet via ethernet rather than sharing it via WiFi.
    For the record, what I have tried so far is, enabling and disabling all options, trashing preferences, creating a second administrator account on the iMac and trying from that one, switching multiple ethernet cables just in case, and even switching to a different wireless network (we have two in my home on different wavelengths).  It's always the same: devices recognize that they're connected to the ethernet port on the iMac.  The iMac recognizes it's connected to them.  They can obtain their own IP addresses through DHCP, but they cannot, under any circumstances, actually connect to the internet.
    Please help!  I'm tearing my hair out over here, as this was crucial to my setup.  Updates shouldn't work this way.

    As with other situations where a window is not visible, it is likely just off-screen where you can't see it. If your main "Final Cut Pro" window becomes inactive (close, minimize, and zoom buttons turn grey) when you attempt to open the "Background Tasks" window, this indicates that the window is definitely opened, it's just offscreen somewhere.
    You can solve this problem by forcing FCPX to gather up all of its windows without having to delete your preferences:
    1. Attempt to open the Background Tasks window in FCPX,
    2. Switch to System Preferences->Displays and change your display resolution,
    3. Switch back to FCPX and verify that you now have your missing window back,
    4. Switch back to System Preferences and change your resolution back to its previous setting (likely the "Best for display" radio button).

  • WiFi Internet Sharing Suddenly not Working

    I'm using a MacBook white early 2008 with Lion 10.7.5 installed on it
    I have been using internet sharing features to share internet from my ethernet to WiFi for several years, and it's working fine
    Suddenly today when i'm using iPhone, it stopped working.
    My iPhone can connect to the WiFi network, but it can't connect to the internet shared by the MacBook.
    What is the possible solution to this problem?
    Is it hardware related? Maybe because i use the Internet Sharing features too much?
    ps : When i'm using the WiFi to connect to another network, it works perfectly fine.

    FYI - I spoke to Apple support earlier and this is still not an acknowledged issue. Ergo, no one is looking into it.
    They have 'offered' to call me back when at home to go over my setup that was working fine in IOS5 but not IOS6 as the setup MUST be the issue. Not sure if I made things worse by pointing out that I'm and IT consultant and have worked with Apple systems for more years than I'd care to admit to.....
    The support tech I spoke said that her home sharing works fine. Hmmmmm.
    I'd suggest that EVERYONE puts in for a support callback (you can go through the iPad option and chose the 'I should get an exception for updating to ios6' option) and get them working.

  • My Refine Edge in Photoshop CS6 has STOPPED WORKING, please help!

    Photoshop CS6
    Windows 8.1
    I have been using refine edge with no problem for months.
    everything worked great!
    I was able to extract out hair and edges very, very, very well...
    but about 2 weeks ago...something changed... the refine edge brush no longer works.
    When I click on Refine Edge... instead of a brush icon, I get the CIRCLE with a SLASH and my system keeps dinging because the tool is just not available.
    I deleted my preferences...but it is still a problem
    NOW... when I adjust the sliders, i don't see a preview of the adjustments...
    Please help!!!!

    no difference.
    i have tried to check and uncheck everything...
    if i adjust the sliders, i get NO Preview... but when i click OK, the resulting photo has been completely ruined by the tool...
    I tried deleting preferences...no change
    the weird thing is that this problem was very sudden.  Just a few weeks ago, I was using refine edge with NO PROBLEM. it is my GO TO tool for extracting people out of pictures...
    but then one day, it just stopped working...
    Do i need to reinstall CS6???

  • Sudden stop.  Please Help!

    Yesterday, while listening to my music from my PowerBook to my stereo via my airport express, the music suddenly stopped. Literally, mid-song...the music just stopped playing.
    Ever since that point in time, I can no longer connect to the Living Room speakers. Internet still works just fine on both my computers. When I click on iTunes and switch from Computer to Living Room, it gets stuck on the "Connecting to Living Room" with the stop button available.
    Any ideas as to what happened?

    P.S. I can't even make this stuff up....I bought my Airport Express 92 days ago. I actually believe there is someone out there who's out to get me. It's a conspiracy theory for sure....but this kinda stuff happens to me all the time!!
    Any help would be greatly appreciated.

  • Ipod nano 6th gen touch screen stopped working please help

    Everything on the ipod nano 6th gen is working except the touch screen and once it goes to sleep i have to hold the sleep button and the volume down button to turn it back on. I went into the volume -, sleep, volume + menu and went through the tests and in the touch panel error check section it says i have IC error reported: 0xFFFFFFFF. Please help as i have reset and restored and update itunes etc. Do i need to send it in to apple? The touch screen was working at one stage and then i disconected from the computer while it said eject first (this is when the touch screen stopped working) and put the ipod on a different computer. The first computer was windows 7 which i used just to charge it a little and the second one im using is windows vista.

    I have had the same problem and changed three Nano's. Each time the fault is diagnosed by Apple as "water damage".
    If you take your Nano to one of their maintenance centres they will look into either the headphone socket or the power dock and and tell you that you have infringed the warranty by somehow getting the thing wet.
    Basically is a poorly designed piece of kit whereas a simple shuffle is way more robust.
    I have given up with my Nano and am now using an old model
