IMAC AIRPORT PROBLEM

Jag har 2 imac datorer och på den ena fungerar internet utmärkt men på den andra så står det att jag är ansluten men så står det !ingen internet anslutning. vad ska jag göra för att kunna fixa detta?

I'm not an expert, but this is what appears to have worked for me.
I connect wirelessly to the net. Till I installed the updates -- for first 8 hours -- no problem. Then I installed the updates. Problems. My iMac would say I had net but every time I tried to connect, no. I installed more updates. No net. I tried everything. Yesterday I finally ended up wiping the HD, reinstalling the OS, not allowing updates to Airport or the OS. Since I have had a strong net connection (24 hours).
Again, no expert but this appears to have worked...least for the last day. Maybe my experience might be helpful for you or someone else.

  • Intel iMac airport connection problems

    Hello,
    My new intel iMac connected up to my 802.11g 3come wireless modem/router fine, the strength in excellent (always full or nearly full) but the connection is very very intermittent.
    It will only work for a minute or so but then the internet will go down on the machine for about 30 seconds, then come back on.
    The network file sharing also goes down. Other Windows PCs on the network do not have this problem.
    I have tried the following, none has had any effect:
    [*]Turning off all other network PCs
    [*]Disabling all encryption on the router
    [*]Using different browsers
    [*]Calling Apple support - first they asked me to adjust some networking options, we also setup a new network connection. They then sent me a replacement iMac - it's exactly the same
    The firmware is up-to-date on the router.
    I am aware there are similar posts in the forum, but other people's problems seem to be to do with their speed. None of the solutions have helped.
    Any suggestions?
    Thanks for your support.

    I wasted hours and hours trying to figure out a similar problem with my machine. Apple Support denied all knowledge of known issues, but then I came across a discussion titled "Will Apple react to the Airport problem with the new iMac (Intel C2D)?" - you will find it on the 5th page (at the moment) of these topics.
    It is one of the largest threads I have seen in these forums (113 replies). I tried to add an update, but curiously the thread is now locked - Apple are obviously keen to censor further discussion on the subject.
    Apple do now acknowledge that there is a problem with Airport and the Intel-based Macs. They are supposedly working on a fix, but when that will come is not clear.
    I would urge everyone with Airport issues to pester Apple Support until they solve this problem.

  • Airport problems on new Core 2 Duo (network attachment delays)

    I have just bought 17" 2GHz Core 2 Duo. Lovely machine, but I have some problems with internal Airport card.
    After startup it takes about 5 seconds to attach to the WiFi network I run. Subsequently, if I load iChat automatically at login, by the time Airport comes online, iChat is already displaying "Network diagnostic" dialogue. After you OK it, iChat will not try to login anymore (as opposed to temporarily losing network after successful login where it will log back in on its own.)
    Something doesn't feel right about this Airport on the iMac. After clicking Airport symbol on the top bar it takes few seconds for the menu to drop down and often accompanied with a beach ball. Ping time to a base station during these few seconds increase from 1mS to 100-200mS.
    Things I have tried:
    -Fresh reinstall of just basic OS X 10.4.7 from restore disks
    -Using two different access points (base stations) - 3Com and D-Link
    -WAP, WEP and just open network
    -limit connections to 802.11b mode only (11Mbps and lower)
    -Change WiFi channels and use interference robustness
    -Use PowerBook G4 as a base station in computer-to-computer and Internet sharing modes
    With all the above the behaviour does not change...
    I have a stock iMac model with no custom options, modifications or peripherals. Signal strength is excellent.
    My 17" PowerBook G4 in the same room boots up and wakes up into fully active Airport connection and it "just works" smoothly and transparently. So were all other WiFi connections I had here from Macs and PC over the years.
    I have been using WiFi for 4 years and have done multiple installations including industrial networks, I am also long time Mac user so I have a feeling how it should work so I know my iMac Airport just does not work right.
    I suspect it is drivers/OS issue. This is based on the fact that once established, the link works fine but as soon as OS tries to access the Airport card to reconfigure it (either at startup or prompted by the user), some hiccups and delays occur...
    I wonder if anybody can confirm this behaviour or suggest something I might try to fix this... I want iMac to use WiFi as transparently as PowerBook G4.
    Thanks for your time.

    Thanks, smacman, the bridge solution is brilliant and would work perfectly from technical point of view, however, I am trying to showcase the "Apple experience" to some other people and at the moment I am not winning.
    I am good enough to write shell scripts or even fix low-level source code in C or ASM but I don't want to waste my time fixing it...
    I had a quick look and the problem seems to be with iMac's Airport being very slow during existing networks scan which REQUIRES dropping current connection as channels and modulation changes during the scan. I have locked my router to work in 802.11b mode only. If I could do the same with the Airport on iMac I am sure it would have helped a lot as no 11g or 11a networks were scanned and queried. Forcing it to connect to a specific network did not help. I can't find any file with low-level hardware settings for the Airport, otherwise I'd have a go at it. Maybe I should search Darwin community's help but most probably Apple only releases compiled binary for WiFi drivers with no access to source code or settings.
    One other thought - 802.11 has a different frequency spectrum certifications in different countries and in certain areas allowed frequency range is limited. Maybe, forcing locale to e.g. France (where certified channels are only 1-7) can speed up things...
    I have tried WPA2 encryption as well but I believe the problem is occurring during the network scan.

  • Airport Problem since 10.4.6

    Ever since 10.4.6, I have had issue with airport. It always stays connected to my wireless network.
    however, the internet will periodically stop working (happens several times a day very annoying). I have to turn off airport and turn it on again, to make internet start working again. This does not happen to my Powrbook and PC on the same network.
    Any ideas? Thanks.

    Sorry, this isn't a helpful reply, but I thought it might be worth pointing out that I have the same (or a very similar) problem.
    I'm running a 20 inch Intel Mac, which prior to 10.4.6 suffered from that other horrible airport problem described under the 'Airport Speed Problem' threads on this forum. That has since been resolved by 10.4.6 (network speeds are normal). However, my iMac periodically loses the wireless network when I wake it up from sleep mode (I go from four bars to no signal). To get it back I usually have to switch off my airport card, put the iMac to sleep, power cycle the modem (cable) and router then start up the iMac again, and even this cumbersome routine doesn't work all of the time. I know this isn't a problem with my network because I have several other computers in the house that don't register any change or problem with signal levels or connectivity. My iBook, for example, which also runs 10.4.6 doesn't notice any change.
    I'm surprised not to see more examples of this problem here, as when I spoke to a Mac genius about it, he said it was a 'known issue', though one more common to the Mac Minis. It has to be a hardware problem in my case. Maybe I need to get my airport express card checked out?

  • IMac + Airport + AppleTV

    Hello all...
    I run into a strange situation once it a while. Sometimes when I sync media to my AppleTV, my Airport drops to 2 bars and doesn't work anymore. Normally it is at full strength because it is 30 feet from my Airport Express (802.11g model) but when I sync, it drops one bar with limited connectivity, then drops all the way down to 2, at which point it isn't connected to the internet anymore. Now it doesn't do this all the time, so it's hard to reproduce. Sometimes it will go for two weeks without trouble, but this morning for example, it happens every time it tries to sync. I have to turn Airport off and back on again to get back up to full strength, at which point my AppleTV disappears from the sources in my iTunes, and is a hassle to bring back up. It's a frustrating cycle. Just wondering if anyone has any ideas why this happens and what I can do. This may be an Airport problem, in which case this question may be moved, but it only happens on my iMac, so I put it here.
    Thanks!

    Lighten up Winston, look up the documentation and cases referenced and see that I am in fact stating facts. Plus it is my opinion. There is no need to duel over this opinion... please do not make me out to be untruthful, as you will note - everything is documented at Apple.
    #1 - Yes they did tell me this WEP security info, see case # 90098512 12/29/07.
    #2 - In addition Apple Support on 12/30/07 case # 89978223 recommended the 802.11N because the throughput for 802.11G is much slower. My network does not have a problem using "G" as I stream content as well. It is just slow to transfer data inherently, technically speaking.
    #3 - Good for you, glad everything is working flawlessly for you - maybe you don't have the interference in the UK that we have here locally in the USA? Mine works fine too, but this area does get interference from other IR devices.
    #4 - According to Cheryl ref case # 90098512 - "Not ALL iTunes downloads are recognized by AppleTV"
    It IS a possibility that you don't have all the facts pertaining to the discussions, directives, and problems but they were all documented. Please, with due respect - may we please end this thread? I only stated facts that are documented and that were told to me. Believe them as you wish.

  • Airport problem on Kids account

    I have a problem after reading the latest Macworld I decided to change the security settings on my airport. I changed it to WPA personal. Both my computer and the wife's iMac run fine with no airport problems.
    My kids account though will not accept the airport network password. I have it written down and made sure I typed it in right everytime, but everytime I get a warning saying the password is incorrect. Yes the written password is the same as the network password.
    Any help would be greatly appreciated. Thanks in advance.

    Hi Quack,
    What computer is your kids using?
    I assume you are using the same password you used on your wife's iMac after you set up the WPA Personal Security?
    Also, I assume you checked the password your are using here:
    Airport Admin Utility, select your Airport, select Configure, click on Password in the top menu bar.....the password for this Airport will appear.
    Please respond back I would like to help further.....

  • WRT54G - Cannot access internet but iMac airport says internet connection is fine... what's wrong?

    I use a WRT54G wireless router connected to Mac. All of a sudden, I became unable to access certain websites on my iMac, such as Facebook and Apple homepages. But i can access Yahoo website. I tried resetting my linksys setup but it doesnt solve the problem. When i access my iphone via wifi at home, i am also unable to go into app store, facebook app, and emails with images won't load. I also cannot link my iphone to itunes on my iMac. What happens on my computer when I surf the internet is that the page just loads halfway and stop "responding". But my imac airport says that my internet connection is fine, however my access has become very "restricted". Can anyone tell me what's happening and how to resolve it? 

    To resolve difficulties accessing some websites when connected to a Linksys router you should check the following.
    Checking the router’s security settings
    Checking your computer’s security settings
    Security on the web browser is set too high
    Configuring the Maximum Transmission Unit (MTU) on the router
    Opening ports for secured sites

  • ITunes 6.0.5 and Airport Problem

    A short description of my recent problem is that iTunes 6.0.5 crashes my wireless connection when streaming music to my stereo via an Airport Express. The problem was repeatable and frequent. Reverting to iTunes 6.0.4 seems to make all the problems go away.
    Before updating my MacBook recently to 10.4.7 from 10.4.6, and updating from iTunes 6.0.4 to 6.0.5, I updated my bootable system backup on an external Firewire drive, first repairing permissions.
    After updating my MacBook, everything associated with the Airport Express seemed to function perfectly, except I had massive problems with attempting to stream music from iTunes. When first choosing in iTunes to connect to the external wireless target, music would begin playing and then my entire airport connection would dispappear within seconds. The menu bar throughput icon would go from 4 bars to nothing and my network SSID would disappear from the drop down. After toggling the airport on and off for a while, along with toggling the iTunes external/internal target control, I could eventually finagle a stable connection, which would last for maybe 15 minutes at a time. Then the connection would drop.
    I happened to be one of the early 10.4.7 upgraders who used the non-combo updater, so when Apple announced that files were missing from the delta updater, I downloaded the new version and repeated the upgrade (successfully, indicated by the suffix on the new build number). Again a perfectly stable wireless connection through the 133 MB download; wireless works fine as long as iTunes is not involved.
    The problem persisted after the 10.4.7 re-upgrade. I then tried booting from my external drive backup, into 10.4.6 and iTunes 6.0.4. The problem went away.
    I then restored iTunes 6.0.4 from my backup to my internal drive, replacing 6.0.5. So far, everything is working perfectly again, with iTunes 6.0.4 under OS 10.4.7.
    The airport problem seemed to be entirely on the MacBook side, not the Airport Express, since I never saw the Airport light change from green and the displayed connection time has stayed at x days and counting across all the times the airport connection disappeared, including when booted from the external drive.
    So based on my experience, it would appear that there is a problem with iTunes 6.0.5. Anyone else see similar behavior or, conversely, can confirm that they are successfully streaming from a configuration similar to a MacBook through an Airport Express with iTunes 6.0.5 and OS 10.4.7?
    MacBook   Mac OS X (10.4.7)  

    Just to bring closure to this thread, I am now successfully using iTunes 6.0.5 with OS 10.4.7: the problems I reported have disappeared.
    Contrary to my original post, with more use I saw some drop-out problems with 6.0.4, though far less severe than with 6.0.5.
    It occurred to me that maybe what I was seeing was due to the iTunes app paging, but I could find no direct evidence of that.
    It then happened that I began experiencing the random shutdown problem that some MacBook users have reported (many posts in the MacBook forum). I sent in my machine for repair.
    In the few days since I received the repaired machine back, I have had no random shutdowns. I also noticed I had no iTunes wireless dropouts with 6.0.4. I then re-upgraded to 6.0.5. No problems have surfaced. The only other software change at the system level I have made is to update the SMC firmware, which makes the machine run cooler.
    I have no explanation and speculation seems pointless. (The shutdown repair consisted of replacing the heat sink and top case; as far as I know, no involvement with airport components.) But I'm again a happy camper.

  • AirPort Problems [I know posted already, but read]

    hey guys,
    These AirPort problems are really really getting on people's nerves. 10.5.1 was perfect for most, and now after updating to .2, us .1 100% connection, the connection drops every couple of minutes.
    I'm on a Macbook 2.2 (White), and so I have a question.
    My connection is STABLE, doesn't drop or anything when connected to the MagSafe adapter. As soon as I unplug it, I lose my connection immediately. NOW, if I want to plug my MagSafe back in, my connection won't be stable anymore until I restart my system.
    Is anyone else experiencing that?
    So my question is, is there some sort of power settings for Airport (on the computer, not my router) that I can modify. Cause it seems that as soon as I disconnect my power adapter, AirPort goes crazy and does whatever it feels like.
    *When I OPTION+Click on the AirPort button at the top:*
    *MagSafe in - Transmit Rate: 54*
    *MagSafe out - Transmit Rate: All over the place, 54, 48, 36 then 1, then drop connection.*
    *Sometimes it's, 54 to 1 to drop connection.*
    Hopefully Apple will read this and see that it is most likely some power settings that were modified by accident. I still don't know why everyone doesn't have problems. But of course, that's not the point. Getting an AirPort solution ASAP is
    C'mon Apple!

    I suggest that if you want a response from Apple - you ask them.
    They don't officially monitor these posts. You should be legimately able to all support on an issue like this.
    I don't see this on my MacBook Pro - right now it is showing a rate of 52 and is unplugged. It was 130 early today but when plugged in and in a different room.
    Likely there is some attempt being made by the system to manage the power used by the peripheral devices - but it should not drop the connection.

  • Macbook airport problems linked to battery power?

    I too have experienced the macbook/airport problem, specifically since 10.5.8 came back. When I upgraded to 10.5.8, it was so useless that I just reinstalled tiger. Then Snow leopard came out and I upgraded only to experience the same problem but not as severe.
    I have just been able to pin/point the problem today (mainly because I just grew so frustrated and spent considerable time trying to figure out). I have tried all the other potential fixes posted on here to no avail (changes airport settings, replacing card, changing dynamic IP to manual, encryption etc).
    This is what I have determined and was able to reproduce it:
    When macbook is running on power (plugged in):
    If battery power is below 60%, connection is spotty - the lower it is, the worst the problem.
    If the battery power is above 60%, no problems at all, runs fast and no drops.
    When macbook power is not plugged in and running on battery:
    Below 60% almost useless
    Above 60% spotty and worse as the battery drains
    Can anyone else test this out? I've sent Apple an e-mail.

    I've gone down to maybe 15% without any noticable difference in connection.

  • A possible workaround for C2D Airport problems?

    A collegue advised the other day to download iStumbler, a free application that seems to sit and monitor all connections coming in your Airport, also for Bluetooth, Bonjour, etc.
    Well, I did... and ever since this thing started to work seeing my Network wifi the airport bars has returned back to the maximum level and there has been no connection drops, re-connecting flawlessly after sleep.
    Its funny also how iStumbler is able to see more Network wifis than the Airport menu: I see 2, sometimes 3 connections that I never saw on the Airport menu.
    The signal is reported to be at 70% with a 13% noise. But working great!
    Can someone with Airport problems try this solution and see if it works too? Maybe we are into something?
    Regards,
    -- Carlos

    I had installed istumbler a couple of days ago it did seem to improve the signal for a period then the signal dropped back to the normal 4/5 bars.
    After your post I started istumbler again and found there was an update the purports to solve signal problems with core 2 Duo macs.
    I have updated and have full signal strength for last 5 minutes longer than ever before.
    Fingers crossed

  • AirPort problem after installing Security Update 2007-007

    Help! I installed the security update 2007-007 on my Mac mini os x and now my AirPort is not detecting any signal. Should I backup the system and then reboot? I'm not really sure what to do. I have tried almost everything I can imagine. I checked through the user logs and all was functioning properly until the update installed. All of the settings for the network and internet connect say that they have failed.
    Please help! I am not particularly familiar about backing up -- how do I do this? (please spell out for me, I'm really new to mac!)

  • Airport problem 2

    since apple closed the previous port related to airport problems , now noone can put their experiences, that i think it can help apple to see the problem we are experiencing here. please put all the details so apple will read this and arrive to a good idea of what's going on.
    i have 2 mbp
    1 2.33 ghz ,2gb, 120gb 10.5.1
    2 2.0 ghz ,2gb, 120 gb 10.4.11
    the laptop runing 10.4.11 is also aving issues with the wireless, so is not only the leopard one. now, i downgraded my 10.5.1 to 10.4.10 and i have no more wireless issues anymore with that laptop. so there's a problem in networking software design with 10.4.11 and 10.5 and 10.5.1 . that is what i experienced. i did not want to go back to windows, so i purchased a linux machine to survive junt in case apple will ..... but still have faith, just i'm waiting for months, like others are doing too.

    There's another thread called "Airport Problem" that goes into extraordinary detail about the behavior he's experiencing. Since someone locked the thread it is now being pushed back by current updates to other threads, in this category, but I recommend going back and skimming the comments in that thread to get a better idea of what is going on. You can't miss it, it has 33,000 views and 530+ comments.
    I have been experiencing similar wireless behavior. I installed Leopard 10.5.0 (as an update) and my wireless connections became intermittent: I would see the airport icon in the menu bar indicate full strength, a few seconds later the icon indicates zero (0) strength, and then the indicator shows full strength again. This happens about three to five times per minute, and makes real time tasks, like playing in a raid on a Warcraft server, appear to lag badly for a few seconds up to about three times a minute. My interim solution for this was to drape 50' of cat 5 from the router to my office and wire in. Worked well enough for me to get work done and let Apple take the time to identify and fix the problem.
    I did eventually do a clean install of Leopard, but that did not clean up my wireless signal problem.
    Here's the interesting news, however. I'm using someone else's wireless facility at this moment. That facility used the same wireless router I've been trying to use with Leopard at my normal office location without success. So, predictably, when I first tried to use the wireless router here, I was seeing the same problem. Then a couple hours later, that router's transmitter appears to have died, because nobody here was able to see it on the Airport list.
    We replaced the dead router with a new one of the same make and model (different revision), but with a different third-party firmware package.
    I now have a rock solid wireless connection. It no longer drops signal strength to zero three times per minute.
    This leads me to conclude that while there is still a problem with code in Leopard that makes it not work with some wireless routers that worked fine with Tiger, it is entirely possible to work around the problem by installing a different 50 dollar wireless router. Take your machines and try (with permission!) to use different wireless connections to see if any work.
    I notice that AP Grapher indicates another wireless access point using the same channel as the AP I'm attempting to use, and the app also shows my transmit rate dropping to zero periodically. Nevertheless, the wireless appears to work now. I'll be changing my own wireless access point shortly.
