Airport troubles

Hello all. I'm new to macs so I'm wondering if I got a broken airport module or something. Is anybody else having problems with their Airport on the mini connecting to their router?
Currently I got 2 PCs and an Ipod touch wirelessly connected to my router (Linksys WRTG54GS, latest manufacturer f/w) using WPA-Personal security with AES encryption. They connect to the router and are able to go on the internet.
My new mac mini doesn't connect to the router reliably. Network name is set to the SSID. Security is WPA personal. Password is the correct network key (tried both hex and regular word for password).
If I reboot the mac the Airport is able to connect to the router fine (4 bars on the status icon) and gets it's IP info correctly, then 10 or so minutes later it freakin scans for a new network and loses connection...
Right now I'm using a USB wireless modem to connect. I just hope I don't have a bad Airport module.
I downloaded all the Software Updates from that apple menu too.

I just upgraded my RAM and took the opportunity to examine the antennas closely. I'm just guessing here but basically it looks like the wi-fi signal comes out of the top of the mac mini in a sort of hemispherical shape. This might explain the poor quality signal coming from the mac mini in my previous post. In my case the router and mac mini are at the same height.
It's been only one day but ping tests to the router were more consistent after tilting my mac so the top is sort of facing the wireless router. In other words I stuck a 1.5" thick book under the front end of the case heh. Another alternative might be raising the router up higher.
If anybody is curious here's an extreme case of one of my ping tests with the mac mini level on my desk:

Power trouble, AirPort trouble, trying to upgrade from 10.3.5 to 10.3.9

I have huge problems. I posted in the QuickTime forum because I had trouble uninstalling 7.5 and reinstalling 6.5.2 to be able to run ProTools on OS 10.3.9.
Since then, I archived and installed from my Panther discs. I now have 10.3.5 and am unable to open some of my programs. Could this be because I'm running 10.3.5 instead of 10.3.9? I could try to remedy this, but that leads to my other problem...
My iBook will not connect to my home wireless where I currently am. I'm online on my PC laptop right now. I can get online anywhere in the house on this thing, but only downstairs on my iBook. Where's the problem, you may ask. Well, my iBook WILL NOT RUN when the power cable is unplugged, even though it says the battery is full. Therefore, if I want to quickly use wireless to reinstall software, I have to unplug everything upstairs and plug it all in again downstairs.
Therefore my questions are...
Why does my iBook shut down and reset the date to 1970 when the power cable isn't connected?
Why does my wireless only work about 2 meters from the router?
Can I download a 10.3.9 update onto a PC and transfer it to a Mac?

emeraldbluerose:

You do not tell us which iBook G4 you have (processor speed?), but to the best of my knowledge you don't have a PRAM battery. The issue most likely with the main battery. The normal life of these batteries is 3 to 5 years, so you are likely due for a new one. So, why does it read as being fully charged? I don't know. I do know that if the clock resets everytime you unplug the computer, your battery is not doing what it should. I would begin by Resetting the PMU.
In terms of wireless connectivity, I would rather get the power issue resolved before attempting that. However, I suspect that your Airport Extreme card needs replacing.

Airport trouble - Link down on en 1

I get some trouble with my airport connection - some lose of network a few second as my Aiport Express seems not valid.
This is a sample of log but i can't really see what i must do ?
This is a new mac and i have restarted my Airport Express to created a new Network.
The problem occurs each 5 or 10 minutes.
Help is welcome !

Hi
you don't say what wireless router it is... if an att model, then this may help
http://utalk.att.com/t5/High-Speed-Internet-Access/Suddenly-laptop-will-not-conn ect-wirelessly/td-p/211083/page/2
if not att, look for something similar in the router setup pages.

Generic Airport trouble on all MBPros?

Hi there!
Recently, I got my new MBPro (Core Duo) with this integrated Airport chipset onboard. At home, I use a DLink614+ to connect all my machines (iBook, PBook15", PC WinXP, iMac G5) and everything worked without any hassles.
But now, as I wanted to connect my MBPro to my network, problems occured apparently without end...first, it wouldn't accept WPA, so I switched to WEP. Then, it wouldn't find the DLink network and loose it randomly or after sleep. The latest problem now is that it seems to connect/reconnect to my DLink every 15 secs (...yes, I've tried every fix and trick possible) !
Runnig through the forums here, I can tell that nearly everybody seems to have trouble with these portable Mactels when it comes to Airport connectivity.
Can anyone help me? Or maybe should we send a general complaint to Apple so that they will fix this problem ASAP?
RFC...

Go to System Preferences
- Click Network
- Highlight AirPort and click Configure
- Choose "By default, join: Preferred networks"
- Select your access point and click edit
- Click on "show password"
At this point you should see a crazy corrupt password.. Proof that it is jacked up. Now:
- Exit that window back to the access point list
- Remove your access point with the "-" button
- Launch your keychain and delete your access point keychain entry.
- Reboot
- Go back to the "By default, join:" page and click the "+" this time to add your access point. Enter the correct password, save, reboot, should be ok now!
or try this as once someone suggested:
If you use "Preferred Networks," instead of "Automatic" for your "By default, join" setting, try the following:
- Delete all preferred networks with encryption
- Add them again after manually connecting
It will be faster if you turn on "Automatically add new networks to preferred networks list" under "Options" of the AirPort network connection.

Early 08 Mac Pro Airport Trouble

Hi all,
I ran into a slow internet problem on my early 08 Mac Pro (x x 2.8 GHz Intel Xeon, 4 GB DDR2).
I've had it hooked up to internet via ethernet cable for about a year now and everything was fine. Last week, I moved the computer to a sunnier room (guest bedroom was too dark, gets kinda depression). Since I didn't have an ethernet cable long enough (and there is no cable outlet), I started using Airport to connect to internet. The Router and Modem are still in my guest bedroom. I immediately noticed that my internet connection has slow to a crawl. At first I thought I was out of range for my router (the rooms are not that far apart, but it was a valid theory). So I tested with my laptop (MBP 15'' early 09), iPad and iPhone sitting on the same desk as my pro (pro is under the desk, of course), all worked fine on the wifi (with my laptop clocked an impressive 13.97 Mbps download and 5.59 Mbps upload according to Speedtest.net).
When I opened network diagnostic window, I noticed the ISP / Internet/ Server lights keep switching from green to red. Has anyone seen this before? Do I have a bad Airport component? Is there a test I can run?
Thanks.
Angela

The changing Wi-FI Icon, showing signal strength of one to five bars does not always tell the whole story.
One problem with these things in cities is interference from neighbors' networks on the same channel, or "Network Hopping" if you have not told your Mac explicitly to use only your Network.
In 10.7, there is a tool to show detailed signal strength information:
http://subrosasoft.com/blog/tips-and-tricks/hidden-wi-fi-diagnostics-tool-in-mac -os-x-10-7-lion
You can also use the free utility istumbler:
http://www.istumbler.com/
It is not an accident that almost every troubleshooting guide suggests you power cycle your Router as an early step. This will tend to force your Router to find the least-busy channel and use it.

Airport trouble

First off, i love my new macbook pro. For starters here are the specs(to help troubleshoot my problem):
2.4Ghz Intel Core 2 Duo
2GB RAM
OSX 10.5
160GB 5400 RPM Hard Drive (its actually 148GBs, they always lie about that haha)
when airport is working it works great. the problem is that, sometimes if i shut the lid, or if i go out of range of the airport, and come back, then the connection doesn't work. It will show full-signal, but wont be able to load anything at all. so it sounds like a firmware/software issue. I have not installed the latest update of leopard, because i need to make a backup with timemachine before i do that.
does anyone know if that update fixes this issue? i think the update makes the OS version 10.5.1

AirPort troubles (though AirPort doesn't think so)

OK, so for a long while (soon after I upgraded to Leopard I think), I've been having problems with the AirPort connection to my modem/router. Basically, I can connect fine and the internet works perfectly for a few minutes, but then suddenly I lose my internet connection. The weird thing is AirPort claims to still be connected to my modem, but this can't be right since I can't access my modem via its IP address when the problem happens. Sometimes just waiting a while fixes it, sometimes not. What will always fix it is turning AirPort off and then back on (i.e. reconnecting to my modem) but that's just plain annoying.
I know for sure it's a Leopard problem since when I boot into Windows, I don't experience the problem at all.
Anyways, I know a lot of people have been having AirPort issues on Leopard so this topic probably won't help me much but I had to just get it out of my system. Hopefully an update will come along that actually fixes the problem.

I'm still at work so I'll try and see what I can do, but I don't think it's the 10.5.5 kext specifically that does the trick. I used this one because my wifi was broken under both 10.5.6 and 10.5.7. If your computer worked ok with any of those two, I don't think you need to go back as far as .5. Just use the kext from whatever OS worked.
Using a Time Machine backup is easy, because you just have to select the file in your backup and click "restore" ( and reboot afterwards of course). The file is located in /System/Library/Extensions. If you don't have a backup, you should use a software called Pacifist (it's a shareware, with a trial version), which enables you to "open" and search for files inside an installer package (.pkg files) or an installer disk image. Just download the combo updater for whichever OS upgrade you need (from the apple website), open it with Pacifist, and look for the kext in /System/Library/Extensions (same as before). I think there's already an install feature in Pacifist for the file you extract (by the way, "kext" stands for "kernel extension" and as far as I understand it is basically the driver for whatever piece of equipment it's related to), otherwise you can use a freeware called kexthelper b7 to install it. Just make sure you have a back-up of your data and of the "correct" kext for 10.5.8 in case anything goes wrong (once again, while I'm right now typing from my newly-reconnected-to-wifi-when-on-battery-power macbook, I don't think messing with system files is a recommended procedure....). Also, kexthelper will only work from an admin account, and requires identification (I guess it's the same with Pacifist, I never tried to install anything with it).
Credits for this method should go to users Kuro-to and mach.wolf from this thread :
http://discussions.apple.com/thread.jspa?threadID=2106968&start=0&tstart=0
I just thought it would work in my case too (and it did !)

Sudden and severe loss in AirPort reception

I use my TiBook at my desk (12 feet from wireless router) and on my couch (9 feet from wireless router). AirPort reception has been very strong (always five bars) for more than two years in these locations. I was even getting good, consistent reception throughout my entire condo. I have moved/added no furniture nor any other possible sources of interference.
Suddenly, reception is severely fluctuating and impacting network communications. I am never getting five bars, now. Reception varies wildly and quickly: 15 seconds of four bars, followed by 10 seconds of no network connection, followed by 20 seconds of two bars, etc. This continues even if nothing changes—for example, if I step away from the TiBook and watch the screen from several feet away.
I have tried the following without results: reseating the AirPort card and confirming the antenna is securely attached, pressing against the inside of the battery compartment to reseat one antenna, rebooting the machine (several times), small adjustments to the router antennae, subtle repositioning of the router, reseting the router, setting wireless communications from G to the supposedly more stable B, trying several channels other than the default channel 10. Nothing helps.
I have been reading about connectivity issues, but nothing suggests I should be having AirPort troubles when only 9 feet away from the router! I have run out of ideas. What am I missing?
J.

And another afterthought: I just picked up on rereading your post that you live in a condo. That suggests the possibility that someone in an adjacent or nearby unit may have installed something new in their unit that has caused increased interference for you. You obviously have no control over that — perhaps not even the ability to discover whether it's true. If you can't find any indication that either your router or your Airport card is malfunctioning, you may need to switch to using a wired connection, inconvenient as it may seem.
In my own home (which is several hundred feet from any external interference source), I was stymied for a long time by limited wireless range to distant parts of the house, porch, deck, etc., and I couldn't face having to run ethernet cables all through my existing walls. I solved the problem with two of these ($48 for the pair, shipping included, on Ebay). They work extremely well in my situation, but they might be vulnerable to power line noise in yours; I don't know for sure. Of course if you only use your Powerbook in the same room with your router, using a simple patch cable to connect them wouldn't be much of an inconvenience compared to having your connection dropped unpredictably.

10.4.6 Airport Broken ICMP

I just installed 10.4.6 and all of a sudden, I'm completely unable to ping any host outside of my subnet. I completely flushed the firewall rules, which didn't help. My routing table is fine and everything appears to work except ICMP.
Did 10.4.6 break ICMP?? I can ping hosts within my local subnet, but not outside. Every other system on the subnet, including the mini running 10.4.5 can ping outside with no problems, so the router is not the issue.
Anybody else experiencing these terrible ICMP issues?
Update 1: One more thing.. I'm using the airport extreme (en1) interface. It will be interesting to test the ethernet interface.
Update 2: Just tested the wired ethernet interface. ICMP is fine. This means that ICMP is broken for the airport interface.

Hi Adam,
Did 10.4.6 break ICMP??
I can do ICMP just fine from my AirPort network, several users are reporting AirPort troubles but most of them are DHCP-related. If ICMP was broken then most likely other protocols would be broken as well.
Did you update your AirPort software lately?
Try flushing the lookupd cache from the Terminal: lookupd -flushcache
Did you check your port mappings on your basestation (if you use one)?
Did you try to run a tcpdump on en1?

Lost Airport express base station

Hi there ... like many I am having airport troubles after installing leopard. Initially things were working ok ... my (1 month old) imac could see the base station without any troubles and access to the internet was great. Then, a software update said I should update the firmware on my airport express. After that ... no more base station. Airport sees about 9 other networks in the area, but not mine. The weird part is that old power book (running 10.3) also cannot see the airport base station. I have tried resetting my airport express to 'factory settings' by holding down the little button while plugging it in but that hasn't helped. Very frustrated ... any ideas?

this just happened to me too.... how do you fix it?
thanks!

Can't connect to airport network

I have had massive Airport troubles since upgrading to 10.5.2. I recently upgraded to 10.5.3, hoping that would solve my problems, but it has not. It got so bad that I gave up and installed an ethernet network in my home office. But I would like to have the portability of Airport again so I'm hoping I can figure this out.
Right now I cannot even connect at all to my network. I have two computers - a Mac Pro and a MacBook. My network shows up with full strength on both, but if I attempt to connect, I am prompted with a password dialog box. The password is stored in both computers' keychain, so I click "okay" and I then get a "connection timeout" error. The password is correct, but neither computer can connect.
The router is a D-Link DIR-655. I have checked the settings and everything is as it should be. The password is WPA Personal and I have triple-checked it to make sure it's correct. I am getting great signal strength so that's not the problem. I simply cannot connect with my Macs.
Thanks for your help.

Make sure the router is in bridge mode
and both Macs using DHCP

Internet Dropouts and Internet Connection Trouble; POSSIBLE SOLUTION

Here is something that might help
I have had problems with this on my old G5, Intel Macbook, and More Recently my Mac Pro (past 4 years I have airport trouble)
I spent hours trouble shooting, the thing that ends up working for me three times so far has solved my problem
Here is a step by step instruction of what I did (continue anyway if you are not receiving the same circumstances/results)
Remember this is also a diagnostic method for yourself to see what is working and what is not so you can solve the problem. Also I still get network drop outs and sometimes internet performance decrease but a lot less frequently by performing the steps bellow. If your problem persists then I might be able to trouble shoot with you. In no way this method will be successful and your problem may become worse so use discretion when applying the steps below
1)Check "Console" to see whether broadcast is being dropped (utilities folder)
2)Make sure your problem persists with all other applications not running (including your virus software)
3)Reset Safari and continue loading to see if network performance is still hanging up
4)If slow loading persists/airport drops shut down computer and boot into safe mode by holding shift key (this empties cache stuff and does a few repairs)
5)Load Safari and see if slow loading persists (while in safe mode)
6)Go to disk utility and repair disk first (or verify)
7)If disk comes clean then precede to repair permissions, there are many errors that show up that are nothing to worry about "ACL found in different place" is one of them.
8)Shut down, (do not restart and wait for 10 sec, I have no idea why this happens and it does not make sense to me but I have restarted and ended up with some other problems)
9)Turn on computer and proceed to disk utility again (do not worry about airport, do not touch yet
10)Verify disk again (remember not in safe mode)
11)Repair permissions once again (different things are loaded into the permission system; plugins ect.)
12)Shut down computer again
13)Turn on computer and proceed to open network preferences and remove airport service (make sure your changes are applied)
14)Open key chain access
15)Delete your network password (if it exists) in "login" and in "system"
16)Shut down computer once again
17)Reapply all network configurations in the network preferences panel
18)Shut down computer once again and turn on
19)Check airport performance over the next 30 min or so by clicking links actively and waiting
20)If problem persists you may have corrupted files somewhere and may have to delete some preference files and perform the method above once again (to be safe I suggest running the disk utility test once again)
note: for some reason Leopard still remembers old network information even after deleting it. you need to find a way to keep leopard from using old preferences (it can be any of them). If all thus fails trash your router settings (on your router, factory defaults) and perform the steps above once again)
Please report abnormal occurrences like the "self assign ip address problem in network preferences" so we can narrow down where problems are mostly occurring"

I quote from the System Preferences Help:
If your computer is connected to the Internet, you can share its Internet connection with other computers on your local network.
For example, if your computer is connected to the Internet using a DSL modem and has an AirPort Card installed, you can share the DSL connection with other AirPort-equipped computers.
On Windows computers, sharing your Internet connection is sometimes referred to as a “network bridge” or “bridging your network.”
To set up Internet sharing:
Choose Apple menu > System Preferences and click Sharing.
Select Internet Sharing.
Choose the Internet connection you want to share from the “Share your connection from” pop-up menu. For example, if you’re connected to the Internet over Ethernet, choose Ethernet.
Select how you want to share your Internet connection in the “To computers using” list. For example, if you want to share your Internet connection over AirPort, select AirPort.If you share your Internet connection using AirPort, click AirPort Options and give your network a name and password.

Mac mini Intel Updated to 10.4.10 - Won't boot if Airport turned on

Just updated my Mini to 10.4.10. I have two locations set up - one wired, and one wireless. If the location is set to use Airport, the machine will not boot. It may get to the desktop, but usually hangs before the dock makes it onto the screen. I need to do a Safe Boot, and change the location back to Wired for it to boot. After that, it works perfectly fine until I try wireless again, resulting in the same problem. Taking cues from some of the threads here, I downloaded and applied the Combo update, but it didn't help. It worked just fine under 10.4.9, and is completely reproduceable under 10.4.10. I tried turning off my Linksys wireless router to see if talking to it was giving Airport trouble, but even with the router powered off, the mini still hangs.
Saw some other threads about people having difficulties after 10.4.10 using HDMI to an HDTV, which I am also using, so maybe there's some combination of DVI->HDMI monitor and Airport???
Mac Mini (Intel Duo) Mac OS X (10.4.10) DVI->HDMI->Vizio GV47L HDTV

Curiously, of the 3 users I have with Intel minis who updated to 10.4.10, none have boot problems with Airport enabled. None are using any unusual adapters etc, but the systems are behaving correctly none-the-less.
However, there are obviously some users who do have problems, and just to be clear, since this is a user-to-user support forum, Apple do NOT read these threads. Well, to be more accurate, the forum hosts do, but solely from the standpoint of 'policing' content, and from time to time other staffers may, though not for the purpose of identifying technical issues. It is expected that users wishing to report a problem contact Apple directly to do so, and for all those suffering this anomaly (and others like it should they occur) it cannot be stressed too much that if the answer cannot be found here from another user, contacting Apple directly to make them aware of the problem is the best way forward.
In many instances, these issues turn out to be caused by issues that already pre-existed in the system before an update was installed, but in other instances where there is a genuine issue with an update and a specific piece of hardware or software or in certain operating circumstances, often the only way Apple will know is if users report it to them directly so they can then examine the details of each reported case to help identify the cause and then release a fix if it is necessary.
A useful resource for reporting and troubleshooting issues like these is http://www.macfixit.com/ though it's interesting to note that they don't seem to indicate this particular issue has been reported to them. They do, however, have a comprehensive guide on reinstalling MacOS at http://www.macfixit.com/article.php?story=20070709083546267 for those who want to downgrade from 10.4.10

IBook No Longer Connects to the Internet

Arrrgh. Everything has been fine for the 6 months I have owned this. Just last week, it would not connect to the internet via Airport at a local internet cafe that I use daily. Nothing has been changed to my knowledge with their settings and I went and tested the machine at 3 other places where it would always connect. Now, all I get is a signal (4 bars), but it will not connect. It says that Airport is connected to the Network, "XXX", and gets a self-assigned IP address, but nothing more. It says that I am connected to the internet via Airport. Using 10.4.4.
iBook G4 1.33 Mac OS X (10.4.4)

Hey boys. This is what we suspect. The iBook wasn't picking up the right IP address. It was set to DHCP, but my IP was 172.16.31.100. That made me raise an eyebrow. At the "n" test sites I tried it on, it seemed that the latter IP was the one being picked up. Now I have connected successfully, but the IP is 172.16.31.233. I am thinking that the IP was either bunk or it was the same as another on the network, thereby not allowing me to connect.
Network Diagnostics did say that, "You have a self-assigned IP address and you may not be able to connect to the internet." So I guess the IP was the problem. To all those having Airport troubles, check it out, your IP might not be right. Since all this is usually auto without the user intervention, it was tough to troubleshoot it.

MacBook Pro won't shut down. At all.

I have been googling this for days now. The only way I can shut down my core duo macbook pro is by holding down the power button. Using the restart and shutdown options in the menu don't work. At all.
When I try to click shut down nothing happens, I have tried waiting as long as an hour and it doesn't quit any applications or shut down.
I have tried quitting all open applications first, still no luck. I have tried resetting the PRAM, no luck.
I need to update the firmware to version 1.2 and I can't because the MBP won't shutdown by itself and a hard reboot won't let me upgrade the firmware.
Please help!

I am new the forums, i read a lot but don't post. but i think this might be something that will help the shutdown/restart problems. I have recently encountered the same problem and i found that it might be connected to airport wireless. the only thing that i started doing differently was using my airport and that is when i started having the trouble. if i turn off airport before i shutdown/restart then it will proceed with no problems, but if i keep it on then i get the blue screen of death that goes no where. give it a shot and let me know if it works for you. it is a bandaid at least until apple gets their airport troubles fixed.
