MacBook keeps dropping Airport signal

My new MacBook keep loosing ist connection with the AirPort Express.....i'm not sure if its the Express or the MacBook....there is only a few feet of distance between the two and all updates have been added to the MacBook. After 3 bad Pro's and one bad MacBook I really want to keep this unit and any help you guys could give me would be great.....i'm a new mac user. Cheers.

I had the same issue with my new MacBook and thought it was the notebook.
Here's my story: I went back to the Apple Store where I bought my macbook and told them that there is something wrong with my AirPort card inside the macbook that is "defective" because it kept dropping signals. I would get a connection for a few minutes or seconds and then lose the signal the next! The manager had NO CLUE why that was happening and asked that I show proof by reproducing it inside their Apple Store! I told the manager I would like a new one and she was nice enough to exchange it for me at no cost.
After doing my own research, I discovered that the problem was not with my MacBook, but rather it was with my Linksys wireless DSL router. Luckily, all I had to do was update the firmware on the Linksys DSL router and....I have not lost signal since!
My suggestion is to update the firmware of your router (e.g. Linksys, Belkin, D-Link, etc. All I had to do was go to Linksys' website and download the updates and run it through my router system) and see if that fixes the problem. Good luck!

  • When iBook G4 wakes up, it drops Airport signal temporarily

    My wife and I both have iBook G4s and we share the same Airport Extreme network. We have the most current software updates. When her iBook wakes up after being asleep, it temporarily drops the Airport signal. The signal reappears within a few seconds, but it takes 10-15 seconds to actually be able to access a website. Until then it comes up as "unavailable," which suggests the computer is logging into the network every time it wakes up, and that's the delay.
    My laptop doesn't have this problem. It keeps the signal when it falls asleep. What might be causing this problem with hers?

    Thanks for the link. When I started working through the process, I remembered that I had changed the "by default join" setting from "Automatic" to "Preferred Networks" a while back. I was having trouble with my laptop joining networks I didn't want it to. So I did some research and shifted to "Preferred Networks" and removed the networks I was unintentionally joining. My guess is it is this change, and not the 10.4.11 upgrade that caused my issue.
    When I realized this, I didn't finish the steps on the link. I just changed back to "Automatic" and that seems to have taken care of it. If I find I'm having trouble with the Automatic setting, I'll try removing my encrypted network and then adding it back in, as suggested in the article.
    Thanks so much.

  • Macbook keeps dropping internet connection but other devices are fine???

    I work from home & this is making me completely insane. My MacBook will drop the wifi connection constantly, I will be doing things just fine & the all of a sudden I will not be able to load something & any tab/page I have open will be "spiraling" or loading and get frozen up. My gmail contact list will all go to offline and I get a message that gmail lost connectivity.  The bars on the top right of my monitor showing wireless connection will always be there (usually all 5 are dark), and it will say (both under that icon & in System Preferences-Network) that I am connected to my airport extreme.  Sometimes my Skype icon at the top will stay green & logged in, but most of the time it goes grey/offline as well.  I lose connectivity for anywhere from 2 min to 15 min 5-6 times a day (and that is just when I'm on the computer, I'm not on it all day) and then it just spontaneously comes back again. 
    My husband has a MacBook also & will have no problems even when I am having problems, and my ipad will get on our wifi no problem at the same time, so I know it is not the router/modem.  This computer has been giving me trouble for months, with slow connections previously and then not being able to connect to wifi at my mother's house and then in an apartment we were living in temporarily, but I thought once I was back on my own Airport it would be ok and now it is worse. Firefox doesn't work either, so it is not Safari, although I use Safari primarily & it starts in there (and I got to Firefox to double check & see if I can get online in there which I can't).
    I went to the Genius Bar the other day & was beyond frustrated, as the guy 'pinged' google 100 times with no problems, checked settings, ran some diagnostic & visited a few websites, told me nothing was wrong, he didn't know what to tell me and just looked at me like I was crazy, then started messing around on his ipad and ignoring me. When I asked if maybe my computer got infected or corrupted by something he again just stared at me and said there is no known virus for the Mac OS. He gave me NO advice, nothing to look for diagnostially when it occurs again so I feel like I'm at a total loss here. Please help.
    On a side note, in the last week or two Safari is also now not saving any of my cookies/passwords/logins for more than a day or two and I have not changed a single setting. Plus I set up gmail 2 step verification b/c I got a notice that my acct had been accessed from another state (I changed password, etc) and it is supposed to remember my computer for 30 days but I have to get the text sent with a new verification code like every other day because it is not remembering me, which is very annoying.
    Could these issues all be connected????

    Hi Lisa,
    Seems we have a similar problem and it is driving me nuts.
    I don't have the password problem, but my connection drops out for 2 minutes and over.
    If you bring up the diagnostics window from the prompt on the Safari page, when pages won't load again, it will tell you that everything up to the last 2 options is fine.
    I've had the problem ever since I upgraded to the last MacOs, might have been for over a year now.
    Since a couple of weeks I actually found that when no page is loading at all, go to the search field in the top bar of Safari. (my default is Google) it will actually bring up the Google page, then open just any other page and usually that will let you continue to browse the internet untill it plays up again.
    I know it is very annoying but untill a fix or a solution this will have to be the way for me to work around it.
    Finding the time to reinstall Lion is probably the best option.
    Hopefully someone else does have a better solution for the time being.

  • Macbook keeps dropping wireless connection

    Hi 
    this is my first post so be gentle with me LOL
    I have had many issues with BT over the last 8 months, mostly due to the speed I had in my area (was 0.45MB when wired at one point), but I recently started to have an issue with the laptops in the house.
    I have 2 teenagers and luckily for them we all have Macbooks as I have given them my old ones when I have upgraded I am using a macbook pro (less than a year old & wireless N) and my eldest boy is using a Macbook (about 6 years old with wireless G) you might see where I'm going here....
    the problem is the older macbook keeps losing connection on the wireless, I have called and spoken to the 1st line support guys in India but it's a bit of luck if you can understand them let alone find someone who knows what they are doing. As I work in IT I completely understand and normally ask them to read my notes before advising me especially as I had so many issues last year when I was given a number to get through to the priority care team LOL , so far I have tried the following:
    moving the Hub 3 to several locations around the house
    reinstalling snow leopard 
    using a wireless dongle 
    I live in the middle of nowhere so there are no other houses around which have a hub3 sp none can be affecting me and I've checked this by using programs like inSIDDer.
    Finally I thought I'd take it to work to see if I could get the model number of the wireless card and order a new one and guess what it works fine!! So I thought I'd check at a friends and again it works fine for the whole time I'm there.
    Brought it home and it won't stay connected GRRRAAA!!!!!!! 
    I've heard that the hub3 doesn't like having a wireless N & and wireless G laptops on the connecting at the same time is this correct? Has anyone else heard of this?
    finnally I do have windows machines in the house and none of them  (2 laptops and a desktop which is wired) are having an issue but the Sony TV which is wired directly in to the hub will also drop connection randomly between 8 PM and 10 PM every day so I'm leaning towards the hub being a rubbish router instead of the problem lying with my Macbook

  • Ibook drops airport signal, have to reboot iBook to get AE signal back,

    my powerbook is working fine and the AE light is always green, but my iBook drops the AE signal whenever it goes to sleep. upon wakeup the airport is on but no signal and I have to reboot the computer to get the signal back strong even though it's fine on the powerbook. all updates, firmware etc. done. any ideas?

    You might want to try resetting the PMU. It has some control over sleep and wake issues.
    Read about the nightly maintenance routines that run if a Mac running OS X is not shut down or allowed to sleep in this Apple Knowledge Base article:
    http://docs.info.apple.com/article.html?artnum=107388
    If you set the iBook (in Energy Saver Preferences) to just sleep the display (and leave it plugged in at night and open), these routines can run and she won't lose the AirPort signal, either.
    I only close mine when I'm going to put it in its bag and take it somewhere (in that case, it would lose the AirPort signal anyway).
    Maybe the PMU reset will do the trick for you and she won't have to use it the way I use mine (if she doesn't want to).

  • Macbook - Constant Poor Airport Signal

    Hi guys,
    I've had my macbook for about 5 years now, and in the last 3-4 months i've been having some annoying issues with my airport connectivity, i've finally decided to try and sort this out! The problem is that my macbook has become terrible at picking up airport signal... whereas other computers, ipads, xbox 360 and such can pick up the signal absolutely fine, I have to move very close to the hub to get any signal at all. Now for example I am sitting about 3-4 meters away from the hub and I am getting 1-2 bars! ***!!
    Its not anything to do with the network as I have tried in several different locations and with the same results... no signal unless I have literally right next the the airport sender box thingy (hub). Could it be something to do with the software? Or perhaps the airport card is playing up? If so can I get a new card?
    Any help would be greatly appreciated....
    I guess a system spec would also be helpful so I have:
    Processor: 2GHz Intel Core Duo
    Memory: 2 GB 667MHz DDR2 SDRAM
    Operating System: 10.4.11
    Airport Card Info:
    Card type: Airport Extreme (0x168C, 0x86)
    Wireless Card Locale: Worldwide
    Wireless Card Firmware Version: 1.4.4

    Hi Dillweed
    Here are some options that might help:
    - Restarting the router
    - Creating a new location (see below)
    At 5 years old, it's possible your AirPort card is on its way out. If you can't afford to change it then you could try:
    - Connecting with an Ethernet cable (always gives the best connections and faster speeds!)
    - Buying a USB wireless dongle.
    Bob
    PS: Creating a new "Location":
    System Preferences > Network
    Select the AirPort from the left hand side
    Click on the Locations combo box and select Edit Locations...
    Click on + to add a new location, call it "Home" (or anything else you prefer)
    Click on Advanced
    Select the AirPort tab and enter your network name
    Select TCP/IP tab. 
    Configure IPv4 Using DHCP
    Now click on Renew DHCP Lease.  After a few seconds you should get an IP address (probably 192.168.x.x)
    Click on Proxies tab.
    Select Auto Proxy Discovery and Use Passive FTP
    Click on OK and Apply, etc.

  • IPad 3 keeps dropping wifi signal

    Despite having a very strong wifi signal around the house, which my iPad 2 has a strong connection to, my new iPad keeps dropping the wifi signal every minute or two, making using the Internet nearly impossible. To regain connection I just have to go on the wifi settings page (not even turning the wifi on and off) which then gives me the signal again. Ive tried resetting network settings, but nothing works. Please help; this is a real problem and means I can't use my iPad properly.

    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

  • MacBook keeps losing Airport connectability

    It's an older Airport, a white 11g.
    For no obvious reason, my MacBook will decide that it can't connect to the Airport. Reset doesn't help, nor does restarting the MacBook. Only deleting the current Airport connection settings in the Control Panel and making a fresh new on does it.
    Other Macs and my iPod are usually able to connect when this happens, so I have to assume it's a problem in the MacBook, though I don't know what. Hoping someone here might have ideas.
    I'm on OS 10.7.5, but have Tinkertool, so I'm able to make the Library visible if there's something in there I could stand to delete, a preference or something.
    Appreciate any help you guys can offer - thanks.

    It may not help but to answer your question about deleting a Preference file, drag the following two to the Desktop, or directly to the Trash, and then reconfigure your network preferences:
    /Library/Preferences/SystemConfiguration/Preferences.plist
    /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
    If you select either of the above lines (triple-click it) and then control-click (or right click, or two-finger tap) you can use the contextual menu to select Services > Reveal. The Finder will open with the file already selected. TinkerTool is not required to do this and I don't recommend using such third party system hacks in general. Though I believe it's unlikely, that could conceivably be the cause of this problem or others.
    The reason deleting the .plist files may not help is that deleting your AirPort connection preferences alone should have been sufficient. Anything's possible though so let me know.

  • TC keeps dropping Airport connection

    I am using TC with a USB drive and a printer connected through a USB drive. Everything works. Frequently, my Airport connection drops, when I try to reconnect, I get a timeout error on the password. The only way to correct the situation is to un-plug the TC.
    I think that this all started after the last software update earlier this week.
    Ken

    Have you tried changing the channel?
    Have you updated your AirPort software with Software Update?
    One or both of the above seems to fix this problem.

  • IPad 2 keeps dropping wifi signal

    Hi all, I'm hoping someone can help with a very frustrating problem.
    I have an iPad 2, running iOS 6.1.2 (10B146). My home wifi network is provided by BT Infinity (I'm in the UK), via a BT Home Hub 3. Very frustratingly, my iPad is dropping my internet connection, frequently but seemingly randomly.
    The wifi is stable for all other devices (iPhone and laptop), I never experience drop outs with either of those devices.
    I've tried re-booting my router, but this hasn't helped. On my iPad I've tried Resetting Network Settings, but the problem persists.
    When I lose my internet connection, I don't actually lose my wifi signal, the wifi icon remains in the top left corner, and the correct wifi network is still 'ticked' under my wifi settings. The only way to restore my internet connect is to turn my wifi off and on again, this solves the problem until the next disconnection.
    It's driving me mad at the moment. My ipad appears to be fine when connecting to other wifi networks, which led me to think it's a problem with my router. But the fact my other devices are not dropping connection leads me to think it's a problem with the iPad.
    In my wifi settings on the iPad I'm using DHCP, no HTTP proxy.
    Any suggestions would be much appreciated!

    Hmm, the problem continues. Switching to Sky is starting to look more appealing!
    How will changing ISP fix a wireless problem? There will still be the same number of interfering channels.
    If you think the problem is related to the home hub, then simply add a separate cheap wireless access point, that is what other people do.
    You can also use a different router if you wish.

  • Macbook keeps dropping USB mouse

    I have a 2.2G Core Duo Macbook which has performed very well. At work I have been using a kensington USB mouse with scroll wheel for some time. In the last few days, the MacBook will suddenly "forget" that it has the mouse plugged in. On the prefs I have it set to "ignore track pad when mouse is present." If I remove the mouse and reconnect it, sometimes it will reset, but sometimes not. I haven't noticed the problem with other USB devices (HDD, camera).
    I have restarted, reset the SMC, zapped the PRAM and everything else I can think of. Any more ideas?

    I have a similar problem with my Logitech Trackman Wheel mouse, but I know it's not the mouse as it still works in other computers. I've also see others with a similar problem - is there any other possibility other than it being the mouse?

    I have read some blogs here where Jerry Lippey?  has helped. PLEASE HELP!!   My c655d-s5200 satellite laptop constantly drops the wifi connection.  just in the registration for this site alone i had to reconnect about 10 times.  computer is only about 1 year old.  computer has always been very slow, even from day 1.  taking sometimes a full minute or two to change pages.  I never complained about it when it was under warranty.  I just lived with it.   and now that it just out of warranty,  I have changed from mediacom cable to us cellular wifi, I am finding out that I have more problems than I thought.  I have a good 4G singal and I am almost 100% sure it is not a problem with the hotspot.   it seems my computer takes way to long thinking. even from day 1 sometimes it will not print a letter that I know I typed.  It has most of the same problems as the person on a ship overseas did in another blog.  If you havnt figured out yet I am NOT familiar with the computer. or tech terms.  I am one of the dumbest ones on here.  I tried to search and identify my wifi  information by typing (pc diag ) in the search bar and no results came up. As I was going to try and redownload the driver.  I still have the windows 7 that was originally loaded.  I also have NO dates set to restore to.  can someone please help me out.  I am very disapointed with this toshiba computer.  PS it just took over 40 seconds to back space and delete a full sentence I decided not to say.
