Possible fix for OS X 10.5.7,  losing connection after sleep, restart

Possible fix for OS X 10.5.7, Airport, losing connection after sleep, restart, or cold reboot.
Issue: (For OS X 10.5.7 on iMac5,1, Intel Core 2 Duo)
=============================================
- After sleep, restart, cold reboot, even though cannot connect to Internet, but the AirPort bars are still full, as if connected.
- Losing Internet connection after sleep, restart, cold reboot.
Possible Fix:
1.Open Network Preference, click on the Location drop down list > Edit Location... > click on the wheel button > Duplicate Location.
a)Select this newly setup location; Use Diagnostic button to connect to the internet. Select Network or enter WEP password if necessary.
b)Test to make sure you can connect to a web page.
c)Go to sleep & wake up.
d)This time, the Airport bar will start to show correctly. Before, it will always be full even when not connected. Now there will be no bars or grey out when not connected.
2.On the left hand side of the Network Preference Window, there is a list of services, such as Airport, build-in ethernet, built-in FireWire, bluetooth, etc.
a)Click on the wheel button on the bottom of the service list; select Set Service Order...; move Airport to the top of the list.
b)Delete any services which you are sure that you are not going to use, such as Bluetooth, etc.
3.Pick one of the locations mentioned in #1, and make it sure it is connected. If not, use Diagnostic button. If you have to select Network or enter WEP password to connect, make it so.
a)Check to make sure you can connect to a web page.
4.Go to sleep & wake up. The Airport bar should be filled up quickly. Try to connect to a web page.
5.Restart computer. Test a web page.
6.Shut down & Start computer. Test a web page.
7.When everything is working fine, you can delete the extra location that you created in step #1.
8.Click the lock on the left lower corner of the Network Preference window to safeguard the setting.

If my assessment is correct, the LIDE 200 driver is version 14.8.1 and dated 26-Sep-2008. It is possible that the driver will not work with the latest version of OSX. I would advise that you contact Canon and ask them the question.
(Removed link because of the way Flash drives the Canon site).
It is not uncommon (though irritating) that devices no longer work when an OS is upgraded. One has to ask the question if (or why) the driver was not written in such a way as to be OS version independent.

I spoke to Canon over here in Australia. Not helpful at all. In fact they were about as useful as an ashtray on on motorcycle. Having said that the tech seemed to think that there would be an update soon. But that is assuming that Canon are aware that there is a problem with that Scanner under OS X 10.5.7.

  • Possible Fix for Printing Problems in Leopard

    I got this information from Mac OS X Leopard Edition book by David Pogue. Here's his possible fix for printing problems in Leopard...Open web browser and enter this address http://127.0.0.1:631. You'll find youself at a secret "front end" for CUPS (Common UNIX Printer System), the underlying printing technology for Mac OS X 10.5. This trick lets your Mac communicate with a huge array of older printers that dopn't yet have Mac OS X drivers. Using this administration screen, you can print a test page, stop your printer in its tracks, manage your networked printers and print jobs, and more–a very slick trick. Haven't tried it yet...anyone who does let me know how it worked!

    If you literally "checked" them, meaning the checkboxes, that only affects their visibility. To remove them, select one and then click on the "minus" part of the "plus minus" at lower left.

  • Possible fix for errors 11503 and 50

    Here's a possible fix for Error 11503 and for error 50.
    It worked for me and hopefully it will work for you.
    I believe this error is caused by the incomplete downloading of either an update to an app. In my case it was caused by closing the lid on my laptop when I was downloading app updates on a very slow internet connection in a hotel.
    Anyway, here is what I did that fixed it completely.
    Close iTunes.
    Go to this folder : /iTunes/Mobile Applications/Downloads
    You'll find tmp files there. Drag them out of this folder to a temporary folder on your desktop. The Downloads folder should now be empty.
    Restart iTunes.
    All should be fine.
    If it is, delete the desktop folder with all the temp files.
    If it's not, then I can't help further, but that's what worked for me.

    Several possible causes from the info you gave
    Battery level low - recharge it for at least 4 hours till the full charge sign displays (2 prong icon instead of lightning icon).
    Time to Reset the iPod - Press the Menu and center Button for about 10 secs till the Apple logo comes ON, then let go of the buttons.
    your hardisk is starting to give problems, hence the skipping and some song refuse to play. - Do a disk diagnostic - follow this post by tt2.
         https://discussions.apple.com/message/17028567#17028567
    If you have updated any sofware application in Windows, then follow this Apple support procedure
    http://support.apple.com/kb/TS1539
    Most likely you have to do all, as the iPod hardisk filesystem would have been corrupted, or else the iPod Reset would bring it to normal operation.
    Good Luck!

  • Security Update 2007-004 v1.1 did not fix connectivity after sleep

    I installed the new security update (2007-004 v1.1) which was supposed to fix airport cards from disconnecting from their wireless network after sleep...but it didn't fix the problem. Is anyone else STILL having trouble?

    I was having the same problem with connectivity after sleep, but once I used the Security Update 2007-004 v1.1 I no longer that THAT problem, but now I have another,....
    in MAIL, there is definitely a 'long' pause before graphics are displayed. Or while using Safari, the text for a new page will display fairly quickly, but again there is a 'long' pause before the graphics show up. I am comparing the time before the first 2007-004 update and now. Before, the graphics downloaded fairly quickly. In the MAIL program, just clicking on an email caused the graphics to appear, in fact, they were just THERE. But now, again there is that longish pause before they appear.
    Has this happened to anyone else? And ideas what I can do?

    Any news on ios 8.0.3 update? Been waiting for it coz of my slow wifi connection after i updated my iphone 5s to ios 8.

    I have heard rumours of an 8.1 update for developers. I just found another bug in 10.9.5. I am beginning to think that nobody should touch any update from Apple until they can get their very serious Q/A problems sorted out. This is getting bad.

  • Possible fix for unable to eject ipod, files are in use by another program

    If you get the above message and are using itunes 7, this may be a possible fix. Open itunes and connect your ipod. When you get the main screen, uncheck the box "open itunes when this ipod is connected" and then click apply in the lower right of the screen. After your ipod has finished updating (top of itunes says update complete) you must eject the ipod using the safely remove hardware from your tray in the taskbar. Unplug you ipod, close itunes. Now, open itunes and connect your ipod. After it updates, you should safely remove the ipod. Good luck.
    pc   Windows XP Pro  

    Easy way. Reset the iPod, then disconnect when you see the Apple logo.
    Another way. Hold ctr-alt-del to bring up the Windows Task Manager. Go to the Processes tab and look for iTunesHelper.exe and iPodService.exe. Select them and hit the End Process button. Close the Windows Task Manager Window and try ejecting the iPod via the safely remove hardware method.
    

If you are still having problems you can try one more thing. Right click on the My Computer icon and select Manage from the list of actions. Go to the Services and Applications item and from there the services item. Double click on the services item to bring up the list of services currently installed on your computer. Look for the iPod Service and double click on it. From the new window select Stop. Now try again to eject using the safely remove hardware option.
    

If all else fails shut down the computer and disconnect the iPod.

  • A possible fix for adobe reader icons on windows 2000 with SP4

    *This is not a problem! I am posting here because I have received help from some other part of this problem and I have read in other places where people have problems with making the pdf icon appear.*
    If the icons won't show after installing adobe reader 9 on your computer, then there is a possible fix you guys can try. Right click on 'Start' for explorer or click on 'My Computer'.
    Click Tools > Folder Options > File Types (tab)
    Try to find the pdf extension in that long list of extensions.
    Below the 'Change...' button, it should read 'Restore' (i'm not sure about this). Click on it once so that it should now read 'Advanced'.
    The restore function is to restore the icons to those files which have lost their identities, so to speak.

    No issues when setting back as per you instruction below.
    Thank you very much.
    Why would I have such an experience in the first place?

  • Possible Fix for the 3.1.1 app crash problem

    THIS IS A POSSIBLE FIX ONLY!!!
    So like many of you I upgraded to 3.1.1 and after the update all of my apps would no longer work. They contiually crashed to the home screen when I tried to open them. I tried downloading random new apps, deleting all my apps and re-installing them with no luck. I tried reseting the iPod and even restoring it through iTunes. I also tried de-authorizing and re-authorizing my computer. None of these things worked for me. Today I tried to go back to the 2.2.1 update (which is the only one I could find that would download) when I tried to upload that onto my iPod I got an error #20 so I ended up restoring back to 3.1.1 the only difference was i told iTunes to start my iPod as a new one instead of loading it from a backup. This actually worked, the only downside was I lost my favourited websites and all the saved info in my apps but hey, atleast they work.
    So long story short try wiping your iPod clean and restoring as a brand new one with the 3.1.1 and it might just just work.

    I just purchased the 64GB iPod touch and it had the same issues from the start. While I had the same issue with the apps I also had intermittent problems with movies not working. I reset the entire iPod touch 64gb and re-synced as 'new' (described earlier) and it is working for now. I am planning on loading some new apps and movies and re-syncing to see if it stays working.
    Also, I upgraded from 3.1.1 to 3.1.2 and everything stopped working again. I am staying on 3.1.1 as long as this solution keeps working until I see something from Apple addressing this issue.
    Apple usually does a better job with their software. I am hoping that this is only a software issue and not a hardware issue.

  • Wireless Problems: Observations/Possible Fix for Some (No Guarantees)

    Hi All:
    I have been following our wireless problem threads. To a large extent, they revolve around lost connections, weak signals, etc. On my machine, I previously noticed what appeared to be wide fluctuations in signal strength, although I could almost always pick up one distant network that has to be at least 125' away regardless of my apparent signal strength. Also, I never lost my connection. I also have noticed that my Windows notebooks pick up more networks than my MBP, even though some must be farther away than 125'.
    Recently, I had to reinstall all my software. Once resolved I'll explain why and what to look out for. Anyway, before the reinstall, I had done all updates. When I reinstalled, I also did all updates. The bottom line is that I have not seen the wide fluctuations in signal strength since reinstalling. Sometimes I see more networks than I am used to seeing.
    Am I suggesting that you reinstall to eliminate the types of problems mentioned above? Definitely not especially if your problem is pretty minor. However, if your problem is significant, then think about it. Perhaps a greater than expected number of partially bad factory installs accounts for some of our problems.
    I finished my reinstall only about 24 hours ago. I'll continue to monitor and will post back if I begin to see the wide signal strength fluctuations again.

    Nope, thanks. I certainly advocate all trying any possible fixes prior to taking the drastic step of reinstalling. Hope the update works for all. I must of installed it yesterday with a number of other updates. Thus, it wasn't what "fixed" my system. But, it looks like it didn't hurt it either. Both are good to know:) Gosh, and looking at some of the recent posts in this category, I am glad that none of the recent updates hosed anything on my machine. Then, I'd me reinstalling again and being more selective about the updates.
    I have to admit I have been throwing caution to the wind on doing all the updates. I think I'd better go back to my old style of seeing if there are update rumblings before I install them.

  • A POSSIBLE FIX FOR RE1000 CONNECTION ISSUES!

    My Amazon Review for the Linksys RE1000:
    I have been an Amazon customer for several years and this is my first review ever. I'm only taking the time to post this review due to my utter frustration with this product.
    Here are the bullet points of my experience.
    1) I consider myself to be extremely tech savvy and pride myself on having the patience to eventually get technology to work.
    2) I have purchased two of these units. I returned the first one out of frustration (also wanted to rule out a defective unit) and spent countless hours trying to make the second one work. As many reviewers have stated this unit constantly drops the router/internet connection. Mine never lasted for more than two minutes at best. It just constantly cycled the connection on and off over and over again.
    3) Linksys Tech Support is provided by foreign nations and proved totally worthless.
    4) I literally tried every tech suggestion I could find online via Google. I did my best to leave no stone unturned assuming somewhere there had to be an answer. If you can find a suggestion online, believe me, I tried it.
    5) After 6 hours with my second unit, VICTORY! Through a rigorous trial and error process I FINALLY GOT MY UNIT TO WORK!!!
    6) My solution (not sure if it's going to be everyone's): 1 - Flash the unit with the most updated firmware via the support site (using an Ethernet cable). 2 - Download the auto setup program from the Linksys website and run it following all the instructions. 3 - Here's the MAGIC TRICK that worked for me. Once you have it set up and running you are free to change any setting in the firmware EXCEPT "WPS" under "Wi-Fi Protected Setup" which is under "Basic Wireless Settings". I REPEAT in the "Wi-Fi Protected Setup" under "Basic Wireless Settings", "WPS" must REMAIN ENABLED and LEFT SET AS IT IS during the auto setup. 4 - Use a static IP address and 20 Mhz only for channel width to ensure a stable connection and to minimize wireless interference. 5 - Verify the proper strength and quality of the signal under "WLAN Statistics" and reposition the unit (and/or change the router channel) as necessary.
    7) I have TESTED this multiple times, turning the WPS on and off repeatedly. My connection drops or stays active based ONLY upon this setting (even after plugging and unplugging the unit from the electrical socket). I can literally set my watch by it. No other setting has this negative effect and I've changed them all.
    8) I suspect half of the reviews are positive regarding this unit because many are simply using the auto setup successfully and then leaving their settings untouched. Unwittingly touch the wrong setting (WPS) and you're back to square one with a useless gray box.
    9) This unit has the potential to be an excellent product, instead it's a nightmare to deal with. My guess is it's a victim of lousy firmware and lousy quality control via Linksys. The shame is it could probably be quickly fixed with a simple firmware update.
    10) I hope this review helps others with their frustrations. I'd be curious to know.

    PS: One last tip! If you really want to play it safe, be sure set your router's LAN IP address to anything other than 192.168.1.1 (use 192.168.0.1 or 192.168.2.1 or 192.168.107.1 for example). That is the default address for the RE1000 and it's been known to cause an IP conflict with many routers that use the same default IP address. Apparently changing the static IP address on the RE1000 is not enough, as the default IP address of 192.168.1.1 still adheres to the RE1000 (hidden somehow) even after the fact for some unknown reason.

  • A possible fix for the email "large attachment cra...

    08, v1507, FP2, UK product code (hacked from original amazon.co.uk Malaysian product code).
    I've just started Nokia Suite to see if anything new comes up.
    No sign of 1508 but one "really interesting" fix for the email app, specifically mentioning the "large attachment" bug. It isn't easy to reproduce because it doesn't happen all the time, even with the 10MB pics from Camera Pro on max jpeg quality settings, but it is good that Nokia (Accenture actually) are still out there reading the forums and fixing stuff...
    No news of any HSPA fixes.
    The attachment fix seems to work but they have now imposed a hard limit on email size of 15.36MB, which is way below what the previous email app was capable of sending sometimes - I have tested up to 50MB on the 700 and the 808.

    Well... they haven't completely fixed it. This morning, doing some tests (of something else) which involved emailing 2-4 images as attachments (total size under 10MB) the email app crashed a few times. As before, the crash results in the email being dropped into the Drafts folder.

  • Possible fix for embed tag problems in Safari 5.1 - Quicktime 7.6.6

    I would be grateful if anyone can confirm the following problem and fix:
    A user of my website reported that embedded audio (mp3) files ceased playing after installing Safari 5.1 on OS X 10.6.8. I updated my test machine's Safari from 5.0 to 5.1 and confirmed the issue. Some audio would play, some wouldn't. Wierder, a random selection of Javascript-triggered embedded audio would report, "Error calling method on NPObject".
    I had a very similar issue with 64-bit Mac Firefox 5 and Quicktime Plug-in 7.6.6. In the case of Firefox 5, the fix was to open Get Info... on Firefox and select 32-bit mode (this also stopped an annoying Quicktime dialog).
    The Safari problem with embedded mp3's didn't occur under a fresh user account, so I came up with a possible fix:
         In Safari, choose "Empty Cache...", followed by "Reset Safari", checking only "Remove all website data" (if you don't want to lose your auto-fill, passwords and history).
    My system seems to have recovered its senses... I'm just wondering if the fix above was what did the trick.
    Cheers,
    Chris

    I followed these steps and it did not fix my problem.  I still click on an mp3 link and it downloads, rather than opening in the browser.
    It gives me the option of choosing, and works both ways (download/open) in Firefox.
    sample link:  AccNoir+Fest+2011+PRA+mp3.mp3
    Curiously, if I click "Open With" on the dowloaded file and tell it to open in Safari, it opens fine like I want.  So it's not that Safari can't, it just isn't being told properly.

  • Possible fix for some dlink routers with wifi issues

    I found something online that stated that if you turn off a feature  called WMM that it can help or fix some wifi issues, and on my dlink  dir-268 it seems to be working. Now without this feature turned off I  could connect to my wifi but not much else, with it off I have checked  websites online and also for the first time been able to download a  300MB+ file.  I dont know if it is still used on the newer dlink routers  but it could be at least a temp fix for some.  For my router it is located under the advanced/ advanced wireless settings
    Please post your results if you find this feature on your router, and list what model you have and if it worked so if it fixes problems for enough people mabe we can let dlink know of this find. could help in getting a fix out for the router firm ware or mabe even the android os.

    Wouldn't really be a fix... more a workaround. However...
    Both my Plus account, and a free test account I set up, don't have reliable push... so I think the problem is a little more complex than this.
    While there has been a theory that free accounts work (which I have not experienced), I don't think Apple or Yahoo have ever stated that push was only intended to work for free accounts...

  • Possible fix for CPU temp problem found.

    Well, one day I decided to take the heatsink off of the nForce3 chip and put some good ol' Arctic Silver thermal compound on there.  I figured it might help with overclocking and whatnot.  When I took it off, look what I found(!):
    Imagine my surprise!  Why did they even bother?  Ridiculous.  After removing their mistake, I put some Arctic Silver on there and re-attached the MSI heatsink (someday I'll probably buy a much better one for it).  I've noticed after a couple of days (it takes a little while for the thermal compound to set in) that the CPU temp doesn't appear to fluctuate wildly anymore.  Before I was getting crazy jumps from 45C to 65C, but now it hovers around 45C-47C idle and a little over 50C stressed.  I've also noticed that my overclocks are a bit more stable now too.  For those of you wondering, I'm using BIOS v1.1 at the moment (haven't tried v1.42 yet).
    Can anyone confirm these findings?  Maybe something else I did fixed my CPU temp issue (I do fiddle with the BIOS quite a bit).  My guess is that the nForce3 has a part in determining/reporting the CPU temperature.
    I hope this actually is a fix for some of you out there, but don't get your hopes up too high until at least one other person can confirm my theory.

    It's very easy to remove the MSI plate. Using a pair of needle-nose pliers pinch the fins on the heat sink on one side together (one at the top, one at the bottom). You don't have to do it too much and be careful. This provides enough slack for the plate to drop out with some slight assistance. Well, that's how I did mine.
    I then attached a 40mm fan by screwing into the gaps between the two fins. Only on the one side mind (so 2 screws in total). It holds the fan fine, no rattling.  
    I have some Artic Silver adhesive and I did consider leaving the MSI plate in place and fixing the fan to it. But I wasn't sure how secure it would be. Plus the plate rattles already, imagine how it would behave with a fan stuck to it.  
    Unfortunately, I forgot to make a note of the NB temperature before I did it. And I can't for the life of me remember what it was. So I can't say, for sure, how it has effected the temperature. I'm sure it has though.  
    I suppose it's easy enough to disconnect the fan to find out. I might try that later...
    Running at 230x10 (stock = 200x10), MBM reports:
    Case = 37C
    CPU = 35C
    Sensor 3 = 49C
    The sensors are labelled by MBM, so I am assuming they respond to the correct items, ie the CPU temp is actually the CPU temp.
    This is after a hour or so with Azureus running, mIRC open, a couple of IE windows and SETI running at ~97% CPU
    When I take the side off to disconnect the fan again, I will take a picture.
