Signal strength from Airport Express dropping to imac (but not Macbook)

I have an Airport Extreme to control my home wireless network. My Macbook Pro works all over the house with no reception/signal strength problems. But my imac, which is situated about 15/18metres away is dropping signal all the time. Any ideas or advice please?
Cheers
Simon

The antenna opening for the iMac is on the back of the screen, so make sure that the iMac is not pushed back into a cabinet or even a corner of the room. Sometimes a small change in location will make a big difference in reception.
Also check to make sure that you do not have other electronics near the iMac like a cordless phone, ampliifer, satellite receiver, TV, etc.
If the iMac is near a window, it may be picking up wireless interference from another network in the neighborhood near you. Try to move the iMac away from the window to a different location.
Power off the iMac and restart after any change in location so that it will establish a new connection.
If you try everthing and the results seem to be the same, then you might want to think about taking the iMac to an Apple store in your area to let them have a look and check out the wireless card in the device.

  • Airport Express works with Skype but not with internet

    Hi,
    I recently bought some new Airport Express' for my company. However, when plugging it in we seemingly get full access, but only Skype seems to work. If I do a search on the internet it can sometimes look like it find the address after a long while, but don't manage to open the page. E.g. writing www.google.com in the search field doesn't give access to that page.
    I brought them home to check if the Airports worked there, and they did. No problem. But at the office the Airports don't. If I connect the same plug which is connected to the Airport into the MAC / PC, then I have full connection to the internet.
    What to do?

    After Grant pointed out the DNS thing, I started to check that part, and I noticed something funny. I called Apple Support regarding the problem, and now it's solved
    Here is my experience:
    1. My Airports worked fine when home, but not at work.
    2. Checking the LAN DNS addresses I received three addresses. 2 in the 158.xx... range and one in the 129.xxx... range.
    3. The Airport Extreme and Airport Express does only support two DNS addresses, and since the two 158.xx... DNS addresses came first in that range the 129.xxx... was left out.
    4. I manually changed one of the 158.xx... addresses to the 129.xxx... address I got on my MAC / PC when I connected directly to the wall and did a "ipconfig /all" on the PC. The three same addresses is listed under network - airport on the MAC.
    5. Now suddenly it all worked. This due to that the two 158.xx... addresses seamed to be internal addresses, and the 129.xxx... address was from outside delivered from our operator.
    Summarized:
    When you receive 3 DNS addresses you MAC and PC can handle it fine, but your Airport not. Find all your DNS addresses and write them down. Enter Airport Admin Utility and do a manual setup. Change one of the two equal address to the third address. Most probably listed as the last DNS address when you are connected directly and type e.g. "ipconfig /all" on your PC or you enter the network settings.

  • Airport Express: Internet Access Works But Not "Seen" in Admin. Util. ??

    Hi All --
    I have a friend with the set-up described below and a seemingly impossible problem. he's asked for my help, and so I'm asking for yours, because frankly the situation just has me stumped. Here goes:
    Set-Up & Other Relevant Facts
    • DSL connection comes out of the phone jack and goes to a Westell model 6100 modem.
    • From there, a short Ethernet cable goes to a Linksys 5-Port Workgroup Switch.
    • Two Ethernet cables exit the Linksys Switch: one goes to a PC, and one goes to an Airport Express (AX).
    • From the AX, a USB cable goes to a printer (a Brother 1440 laser printer).
    • The AX is only about 10 feet from his PowerBook G4 15-inch and he gets a full (four-bar) signal on Airport menulet at the top of the screen.
    • When he first set-up his system, the G4 and the Airport did set up the Brother printer (using the Airport Setup Assistant), and the Brother is listed as a printer on the G4's printer window or such.
    • Both the G4 and the PC access the web fine via this setup (the G4 wirelessly). In System Preferences > Network, the Airport Network is listed, and it says "Airport is connected to the network Apple Network 6c6c1. You are connected to the Internet via Airport."
    Problems
    • When the Airport Admin Utility is opened, no Airport Express appears at all, even when "rescan" is repeatedly clicked.
    How can this be? How can the PowerBook be connecting wirelessly to the Web through the Airport Express, but the Airport Express no be "seen" by the Airport Admin utility?
    • In addition, although web surfing is possible for both PowerBook and PC, neither computer is able to successfully print to the Brother 1440. When he tried printing from the PC, he got the following error messages:
    [Status for LPT1]
    Result=(02)The printer on this port is not responding.
    Status Line=BUSY:H,ACK:H,PE:H,SLCT:H,FALT:H,SLIN:L,HBSY:H,INIT:H,STB:H
    Later, it seemed that printing from either computer would start and then stall, flashing a variety of different signals about spooling or "printer busy" and the like, all of which appeared to indicate things just weren't working right..
    Anyway, the initial questions we're dealing with are the ones in bold above. The printer issues are probably are related and they can be addressed secondarily.
    Any and all help with this will be greatly appreciated. Thanks everyone.

    Thanks for your reply- just to re focus my problem- I
    have no issue with getting a wireless network "green
    light"
    Which is the cable modem correctly giving the Express an IP from your ISP's DHCP pool of numbers.
    - my issue is I can't stream itunes or get a
    usb printer to work off the xpress USB port.
    I have checked everything as my posts explain- The
    reason I have been looking at this thread is I have
    never been able to see the airport in a "scan" per
    JDee post.
    That is odd and doesn't happen on my wireless network!
    Nor have I read in any post that an extra
    ip address is necessary
    All routers have at least two IP's - an external and an internal. When the router acts as an internal DHCP server it hands out many more IP's. Your Express gets one external IP and the default internal one is set to 10.0.1.1 and the first IP handed out is 10.0.1.2, etc.
    However I have seen different subnets- from dncp
    server.
    Are you talking about the external IP's that your ISP is randomly assigning without your control? Are you talking about the different ways you can configure the internal DHCP numbers? If not there's something else going on. Everything on Douglas internal network should have an IP from the Express DHCP server vs. JDee's internal IP's should all be assigned by the modem/router DHCP server. Once you have everything on the same network numbers AirTunes, printers, and Airport Admin Utility lists just work!
    Hey look I really appreciate your help here in
    anyway- I'm really stumped. I want to stream music
    really bad... and just don't see why it won't work-
    its drving me crazy...
    I enjoy a good challenge, especially when they are solvable. After trying all the possible software and connection possibilities there's always the chance it's been a hardware failure all along
    What IP number does your computer have and what number does the Express have? If it's a router it has two IP's!

  • Airport Express joined to network but not discoverable

    I have two airport expresses - an older b/g model and a newer draft n model - both on their latest firmwares.
    December last year I joined them both to the wireless network in a new place and both worked fine.
    I hadn't used either since December - so there my have been some airport utility and itunes updates since then.
    Today I plugged either one in and it synched with a green light immediately - however neither could be found in itunes or airport utility.
    I have tied configuring them - both wirelessly and via ethernet cable.
    I have tried a hard reset to restore to factory default and then configure them.
    They can only be found by airport utility and iTunes under these circumstances:
    1. After a hard reset to factory settings - awaiting initial configuration
    2. Configured as it's own wireless network
    3. Joined to the existing wireless network via ethernet only (WiFi off).
    If I join to existing wireless network as I need to do the device is not discoverable.
    I input the correct credentials and then the device reboots - at this stage it drops out of the airport utility and never gets picked up by it even though it reboots with a green sync light, indicating it is now joined to the network.  Only way to still see it after reboot is if it is still attached to computer over ethernet. As soon as ethernet is disconnected it dropsout.
    I would think it was not broadcasting a wireless signal were it not for the fact that it does work when set up as its own wireless network, and also were it not for the fact that it was doing it to two different airport expresses, both different models.
    I have two laptops - one on leopard and the other on snow leopard and still no luck- so I don't think it is an OS update issue.
    I have never had trouble configuring AEX joined to an existing network before and they both were working December last year.
    So in summary: two different model AEX displaying the same behaviour, two mac laptops with different OS' used to configure, tried wireless and ethernet configurations, reboot after configuration gives green sync light but is not discoverable in itunes or airport utility. Airports ARE discoverable when broadcasting their own wireless network or joined to network over ethernet only. Airports are discoverable after hard reset to factory settings but become invisible when correctly joined to an existing wireless network after reboot.
    Please help - it is driving me crazy!!!

    I'm not trying to set it up as a network.
    I just want to be able to play iTunes on my hifi.
    The Airport Express is currently sat right next to an Huawei HG532 router with a solid green light.
    However both iTunes and Airport utility says: "Airport Utility was unable to find any Airport Wireless devices.... make sure it's plugged in etc...."
    Never had a problem before, but i've just plugged it in after a 4 month absence.

  • Airport Express Shows in WAN, but not Wireless

    I have an old Airport Express and a Time Machine (and Powerbook 13" 2011 model ... OSX 10.8.2). I have been using the TM fine for quite some time now. I used to use the AE, but packed it away for the last two years. Having just gotten a new stereo, I would like to play music via the AE again, as I used to.
    However now I cannot get the AE to show up in Airport Utility. If I plug it in by Ethernet, it shows up fine and plays music. But the moment I unplug the Ethernet, I lose connection. I have tried to configure as Extend a Network and Join a Network, and the same thing happens with both ... music plays fine with plugged in, but cannot get a signal with wireless. AE does not show up at all on AU on wireless. Resetting the AE has no effect. The AE light is solid green the whole time.
    I suspect I am doing something really basically wrong and dumb, but cannot figure it out at all. Any advice would be greatly appreciated.

    ok here's an update.
    now my airport express turns to green automatically (only in my room)
    it will still be blinking amber anywhere else
    so the problem is still not solved.

  • Airport Express for music streaming, but not Internet?

    I currently connect my PowerMac G5 to the Internet via a direct connection. How do I setup the A/E to stream music from my PowerMac G5 (Airport equipped), without disrupting the existing Ethernet connection?

    If you want your G5 to be on the Internet AND stream music at the same time, the AirPort Express (AX) must be connected to your Internet source. The G5 can not use the Ethernet connection for Internet and the AirPort connection for streaming music at the same time.
    If you have a wired router but do not have a wireless router, you could connect both the G5 and AX to the wired router.
    If you do not have a router of any kind (other than the AX), you could connect AX to the ISP connection and then have the G5 wirelessly connect to the AX.
    OR you could connect a wireless router to the ISP connection and then have the G5 and AX wirelessly connect to the router. Alternatively the G5 could be connected to the wireless router via Ethernet.

  • Airport Express connected to WiFi but not visible on iPad

    I have set up the airport express and it is connected wirelessly to my new BT HomeHub (green light on Airport Express).  However, I cannot see it in the choices (I have Apple TV also) so I cannot play my music through my stereo via Airport Express which is how I used to do it with the Sky router.  Am I missing something obvious here?

    OK - Just started from scrath again - and it all seems to be working

  • Airport express working on mac but not on pc

    My airport express works wonderfully on my Macbook Pro, but I would also like my PC to connect to the same network. I have tried everything that I have found online, and the PC will not recognize or "find" the airport network. Does anyone have any suggestions?

    Ok, thanks for the additional info.
    I suggest trying the following:
    o Temporarily disable the WPA/WPA2 Personal wireless encryption, and then, check to see if any of the XP devices can now access the network/Internet?
    o If they can't then, while the encryption is still disabled, change the radio mode on the AX to a non-"n" one, like "802.11g only." You can access this mode, by holding down the <Option> (Mac) or <Control> (PC) key prior to selecting the mode within the AirPort Utility. Can they access the network/Internet now?

  • Airport express wont connect anything but my macbook pro

    Hello!
    I've searched but cannot find an answer to this question so here goes:
    Today I purchased an AirPort Express and was able to configure my MacBook Pro to connect to it problem free.  I've created the network using airport utility but none of the other devices in my household can connect to the network: iPhone 4s, iPhone 5, AppleTV, & iPad Mini.  They all discover the device but none will connect.
    Help me please!!!!
    Thanks!!!!

    Very simple solution: I was in Bridge Mode and switched it over to DHCP and NAT.  Boom....problem solved.

  • Airport express connects to internet, but not print server

    hello all. i hope someone can help me with this. 2 days ago, my wife was able to print using her ibook/airport expess setup. today, the network diagnostics has this message: "network diagnostics was able to connect to the internet but not to the server EPSON Stylus CX3800.pdldatastream.tcp.local. this could be caused by problems with the server, or an internet problem between this computer and the server." she says this happened when she turned it on. what could be causing this? any and all help welcome. mcrat

    You can reset the AirPort Express (AX) following the directions in Resetting an AirPort Base Station or Time Capsule FAQ.
    Then you can use AirPort Utility on your computer to configure the AX.

  • Airport Express connects to MBPro but not to my Lenovo or Blackberry

    I just got the new Apple Express and here's my setup:
    Optimum online cable modem --> Airport Express [Note that I don't have a regular router or Apple Extreme]
    Airport Express software installed on my Macbook Pro 2010 (Snowleopard) to set up the wireless network. After struggling for a few hours, I managed to get my MacBook Pro to connect to the wireless (with and without password). However, I am unable to connect my work laptop (Lenovo T410...my wife has the same and it won't connect either), nor my Blackberry Bold.
    The problem is that the Lenovos and our Blackberrys detect the wireless connection, but fail to connect (or acquire a network address). I am constantly getting "limited or no connectivity" message.
    At first, I thought it was because of my WEP / WAP2 security, but I disabled my security and am still facing the problem.
    I know this is a common problem, have searched forums extensively but have not yet found a solution. Any help will be much much appreciated.
    Cheers

    I've been having similar issues with a Blackberry 9650 (5.x) but I'm using the Apple AirPort Extreme with an AirPort Express as an extender, it seems I've tried everything to get it working (change to WEP, WPA/WPA2, Mixed Mode, 5.0 GHz, etc.), but nothing seems to work.
    Can you see the Lenovo or Blackberry in the DHCP logs of the AirPort?

  • Airport Express USB Printer Visible, but Not Printing

    I've connected my printer (HPc7260) to my Airport Express. It is visible on the network. But print jobs get stopped and the print utility says the printer is offline.
    Any thoughts?
    +This question is also posted in follow up to a thread I started earlier, which was answered helpfully by Duane (thread: How Setup Airport Express for Wireless Printing to HP Photosmart C7280) Sorry for redundancy and clutter. I hadn't followed up on the old thread for a few days. Thought it might not get another response.+

    Solved.
    A restart, followed by reselecting the printer in the print dialog got the job done.

  • Lose network connection after sleep on iMac but not MacBook

    The subject line says it all:
    I installed an Airport Express card on my old Rev A iMac when I got my new MacBook and an Airport Extreme Base Station.
    The MacBook can go to sleep and, when I "wake" it up, it's ready to go.
    After the iMac goes to sleep, its network connection is lost and I have to log back in.
    Any way to fix this so the iMac stays logged in?

    Haven't received a response but didn't want this hanging out there unresolved. Posted same question to Airport forum in hopes of a response there and marking this "answered."

  • PDFs and Word Files open on iMac but not Macbook Pro

    I own an iMac and a MacBook Pro. Recently, I've been having an issue with some PDFs and Word files that have been emailed to me from different contacts. All open—and can be seen using Quick Look—on the iMac. However, on the MacBook Pro it's a different story. When I try Quick Look all I see are the icons. When I try to open the PDFs in Preview (default app for me) I get an error message saying the file could not be opened and might be damaged. When I try to open the Word doc in Word, Pages or Bean I see all of the extraneous header information etc and the text is all mixed up in that formatting junk. I have repaired permissions, cleared out my user cache, restarted—pretty much everything I can think of. But no luck. Thought?

    Brilliant suggestion! I checked all the display settings on my iMac 27" and confirmed they were the same settings as my MacBook -- until I checked the Window 7 screen resolution. Because of its size, I had expanded the screen across most of the monitor. When I changed the resolution to one suggested or configured by Windows, Approach worked fine. I've now tested it on quite a few of the settings, and as long as I let Windows determine the best resolution (on my iMac 27" it seems to be 2043 x 1276), Approach works like it should. Thank you!
