HT4628 My Wi-Fi connection on my iMac drops frequently. The other computers in the house do not have this problem. If I go into the Network Preferences and choose my Network it connects immediately but it does not remember the setting.

My Wi-Fi connection on my iMac drops frequently. The other computers in the house do not have this problem. If I go into the Network Preferences and choose my Network it connects immediately but it does not remember the setting and I must reselect my network frequently.

The iMac picks up a wireless signal from the back of the screen, so you would want to avoid having it close to a wall, or in a confined area where the wireless signal cannot easily reach the iMac's antenna.
We don't know how far the iMac is from your wireless router, or how many walls or other obstructions might be in the signal path that would limit the quality of signal that the iMac receives.
Nor do we know whether you might have a cordless phone near the iMac, or whether you may be using a wireless keyboard and/or mouse....all of which can interfere with the wireless signal.
Can you provide some more info on this?

  • I have the new i-pad and cannot get signal at work.  My original i-pad did not have this problem

    I have the new i-pad and cannot get a signal at work.  My original i-pad did not have this problem.  Any clue?

    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.

  • Having trouble maintaining remote desktop connection with Mavericks.  What is this about needing RDC 3.7.1 with Mavericks.  I downloaded RDC 3.7.1 but it does not replace RDC 2.1.0 previously installed.

    Lucky you, it did not work for many users (which as it should be) so MS produced a new version, for ML and Mavericks.
    It's in the App Store, for free.
    FYI, I assume that you were attempting to post a picture, no one can see it (except maybe you) because it is on your computer rather than the forum server.

    It also looks like you attempted to use Apple Remote Desktop, which does not do Windows.

  • I have the new iOS 6.1.2 on my iPad.  My wifi connects to my home network but keeps dropping it and won't reconnect.  Did not have this problem with previous iOS.

    I have the new iOS 6.1.2 on my iPad.  My wifi connects to my home network but keeps dropping it and won't reconnect.  Did not have this problem with previous iOS.  Apple, you have a quality assurance issue.  Don't be like Microsoft where they send out pieces of junk with testing it.

    Try the following to rule out a software problem:                 
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: 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
    - Reset network settings: Settings>General>Reset>Reset Network Settings
    - iOS: Troubleshooting Wi-Fi networks and connections
    - iOS: Recommended settings for Wi-Fi routers and access points
    - Restore from backup. See:
    iOS: How to back up
    - Restore to factory settings/new iOS device.
    If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

    I am unable to connect wifi on my phone 4s since last 2 weeks... I am living in shanghai and did not have this issue since 2 weeks... iPad works fine... Please suggest some measures... Tried the on off reset settings etc. but no luck ...
    In fact after updating the software to the latest version I am having more of this... Sometimes the wifi button freezes an I can't even slide it to on / off...
    Thanks

    Noooo! Actually I too had d same prob wit my iPhone 4S. When I connect to my wifi network it won't get connected or it wil be grey scaled! I took it to d istore and since I had warranty they replaced my IPhone. It iPad charger has high volt than ur iPhone charger so when u connect wit it, there is a chance where large amount of current passes thru ur iPhone. So for sure it wil damage ur motherboard and its parts! Many said that iOS 6 or 6.0.1 or 6.1 was d reason for tis wifi prob! But apple never made its mistake wit it's software. If and only if u hav hardware prob u wil hav these sort of wifi prob Bluetooth prob! So best way s to replace ur iPhone!

    New Galaxy 5s.  Trying to connect to a guest wireless that routes browser to a login screen.  The wireless will not connect (gives authentication error), so will not pull up browser window.  My previous Android did not have this problem (it would connect and immediately reroute to the login screeen).

    Would you please try manually set the DNS address on client NIC to the IP of your server, then try run the connector again?

  • HT5361 Mac OS X Mail 4.6 sends emails that other email clients don't recognize as attachments, but as embedded pictures. Mail 6.6 does not have this problem.

    My Mac OS X (with 10.6.8 software) Mail 4.6 sends emails that other email clients don’t recognize as attachments, but as embedded pictures. When I receive emails from others, I do not see whole image either. I did change "rich text" to "plain text" in message format - no results.
    My daughter has Mac (10.8.5) with Mail 6.6, which does not have this problem. Can I install 6.6 instead of 4.6 or do you know other fix?
    Help, please?
    Thanks,
    Andrew

    I've been having the same problem now for several months (at least 3-4 if not more). And the frequency of Mail quitting is increasing, several times in a few hours. And as with you, no particular message pops up before hand or not even the beach-ball spinning first and then quitting.
    I too have been sending Apple the crash reports. However, I have not contacted Apple Support yet. Hoping to find the answer in this forum, but again, no luck.
    If you have found a solution since then, please advise. Or if anyone else out there knows of this issue and can help, that would be greatly appreciated.

  • I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Mac

    I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Machine, there are only about 5 backups recorded on the ext. hard drive. There were many more before. Any idea what happened and if I have to buy a new back up hard drive?

    Hallo  Kieth ,
    I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
    Thanks for your interest and advice.
    regards  - Alan

  • The log in button to the Edmonton Public Library is on the top right corner of their web page. But I can not activate it. If I use Internet Explore I do not have this problem.

    If I try to log in to the following site http://www.epl.ca/ it appears that the cursor is not working on the top of the screen. If I use Internet Explore I do not have this problem.

    "'''''it appears that the cursor is not working on the top of the screen"'''''
    Recently, the Yahoo Toolbar and the Babylon extension have been reported to cause that problem. They seem to overlap invisibly over the top of the web page display. If you have either or both, uninstall or disable them/it, or see if an update is available that solves the problem.

    Go to /Library/Preferences/System Configuration
    Move all the files from the System Configuration folder to the Trash.
    Restart your Mac. See if that made a difference.

  • The Local section of the Yahoo front page is stuck on New York, and I'm unable to change it to my city. IE does not have this problem.

    The Local section of the Yahoo front page is stuck on New York as the default, and I'm unable to change it to my city using the normal procedure. IE does not have this problem. This is a new problem that has occurred with the latest version of Firefox. Since the same problem doesn't occur with IE, I've concluded that this is a Firefox issue and not a Yahoo issue. Please advise.
