MacBook airport seems dead

I have a MacBook core duo (no 2) that runs on a wifi network hosted by an airport extreme basestation(those prior to gigabit). I noticed that my macbook could not load pages anymore and connected a ethernet cable. Both my airport and ethernet claim to be working but with a self assigned ip.
The log file shows that a bunch of widgets (apple only no 3rd party) have failed to update.
My iphone still works fine over the wifi and my powermac can still conect over ethernet.
The airport utility on the macbook cant see any basestations the powermac sees them all and reports no errors , so i am quite certain it is the macbooks software that causes the issue.
i am running 10.5.1 with all the latest updates and i also have a bootcamp set up.

Ok, I booted into safe mode now (boot while holding shift) and was able to use the ethernet in this mode, however the system profiler claimed that no airport card was installed.
As I booted into normal mode again I left the wifi off and now I can surf over the ethernet port even in normal mode, but if I try to turn on wifi, I get the same issue as above.
System profiler acknowledges the existence of my airport card, however.
Here is the console-stuff from right around the time it all happened:

I am starting to think it might not be a software issue but rather a hardware problem with my airport card.

MacBook Battery seems dead

Got an Intel based MacBook (black) on 11/2006. Always worked very fine, no problem.
10 days ago, while working on the Windows XP side through BootCamp, the battery came to a sudden end. I shut down the computer and forgot about it since I've been traveling ever since.
2 days ago I got the magsafe charger connected, but the light would stick to green and no battery charge whatsoever happened. The Macbook works only when connected to the power source through the magsafe.
I tried all suggestions I could find on the Apple support blog. No success. I believe the battery is dead.
Still it looks quite strange: no warning came before the battery died. The Mac just suddenly quit working, after which I just closed the lid and left it alone for more than a week.
Any idea anybody? I'm convinced I gotta get a new battery. I have no Apple Care service, so think I'll have to buy one myself.
Thanks for any suggestions.

Just started having this problem with my girlfriends 1.5 yr old MacBook (purchased Jan 07). X in the menu, battery not recognized. Must be a dead battery because it works when I use the battery from my Macbook. Don't believe it when people tell you that apple will replace your battery for free. She was on the phone for about 1.5 hrs getting double talk from apple. Apple will not replace the battery for free but they will sell her one. Looks like they cost $129 from apple. Found a better deal for $89 at http://www.brilliantstore.com/applelaptop_batteries_dekcell_bl_5870_whitereplacement.html
Needless to say she is upset with apple and talking about going back to using a PC. Her 5 yr old Toshiba laptop still has a working battery. So much for apple products being superior.

Macbook airport issues fixed?

I just ran Apple software updated and it include a fix for time machine/airport drivers.
Tada, its all fixed...or so it seems!

My wireless card firmware has gone from 1.3.2 to 1.3.4 but I haven't noticed any difference to performance at all. As soon as I take my MacBook more than about 15 feet from the airport I stop getting its signal, (I used to be able to take it 100 feet from the airport and get a good signal.)
Meanwhile my iBook with 10.4 working with the same airport express can get a signal 100'+ away from it.
If this is "the fix" for Macbook airport woes I'd say we are stuffed. I've just ordered a USB adaptor so I can at least use it when I travel at wifi hotspots.

Unfortunately the Netgear DG834N router is rubbish with Macbook Pro's. I've had a few netgear routers, which were all good with my mac, which is why I bought the 'N' series one as an upgrade to the 'G' version, but basically it crashes my Mac constantly. I get the fade up grey screen forcing my to hard power off my book. everything freezes. It plain just doesn't work. wireless 'N' is still just in draft form and the difference between the Netgear and Mac version on the macbook pro just clash. Netgear haven't updated the firmware on the router since last year, so hopefully the will soon, but I've just gone back to my old 'G' version, and stuck the DG834N on ebay. I tried all the configs, with and with out security and no luck, it always disconnected, froze and crashed.

I saved photos from my Macbook Pro onto my Iphone (using itunes, 4 years ago). My macbook is now dead and I need to get the photos I saved off of my iphone 3GS transferred to a pc. Any help... From my PC I can only access "internal storage"

The iphone is not a storage/backup device. The picture sycn is one way - computer to iphone. The photos are also reduced in size when synced to iphone so they are not of the original quality
It has always been very basic to always maintain a backup of your computer.
Have you failed to do this?
If so, not good at all, you can e-mail the pics to yourself - keep in mind they will never be of the original quality

How can I get a MacBook with a dead display to display to an HDMI monitor upon bootup?

I have a MacBook with a dead display that I'd like to use as a desktop. I also have a 23" monitor with VGA and HDMI input. I am using the DVI adapter on the MacBook, and a DVI to HDMI converter to connect to the monitor. The problem is that when it boots, it's extending the desktop over onto the monitor rather than mirroring or using that as the primary display, which is unhelpful.
Is there a way to get it to use the external HDMI monitor as the primary?
Do I need to buy a mimi-DVI to VGA adapter to accomplish this?
I know this works if I connect the MacBook to a monitor with DVI input. The problem is that my only options are VGA or HDMI for my current monitor.
Thanks!

Yes. Use a Mini DisplayPort to dual-link DVI adapter.

Hi, My network went down earlier in the week. Now it is fine, but my macbook airport no longer detects it and keeps asking for a WAP. When I put the password in, it 'times out'. I'm getting rather fed up.

Hi, My network went down earlier in the week. Now the network is fine, I can connect through the ethernet cable, but my macbook airport no longer detects it, when prompted, macbook will find it, but I get asked for the WAP. When I put the password in, it 'times out'. Prior to the network problem my macbook worked fine everytime. Anyone know the answer?

My guess is all the issues are probably related and fall back to malware.
AVG is probably correct in identifying malware. So I suggest you try some cleaning tools other than Emsisoft .
ones I use (all of them one after the other until I find one that can cope) are;
Roguekiller http://www.adlice.com/softwares/roguekiller/
Malwarebytes anti malware Free http://www.malwarebytes.org/mwb-download/var2/confirm/
ESET online scanner http://www.eset.com/int/home/products/online-scanner/
So first create a clean boot in Windows using Microsoft's instructions https://support.microsoft.com/kb/929135?wa=wsignin1.0 and then run the anti malware applications.
My outside looking in guess is that malware has set itself up as an internet proxy and is is downloading copies of itself and other malware, blocking some mail port as times as downloading more malware is more important, and probably breaking your tivo as well..
Try the malware programs first. If that does not work I will try and talk you through some logging to see what is happening.

My itunes library was on my PC. About two years ago I switched it to my Seagate server/hardrive. (itunes-preferences-advanced-change library). Last summer (2012) I bought a macbook, which seems to access the seagate server hard drive fine for word docs, excel spreadsheets,etc. It also seems to have started its own library which is not complete. My PC died this summer (I still have it though).
Now when syncing any of the multiple devices (ipods,ipads, iphones) that we have with my mac book, itunes states that "an error occurred" or the "app cannot be found". Itunes wants me to erase the device and sync with my macbook. The message "The iPhone “Renee’s iPhone” is synced with another iTunes library on “Renee PC”. Do you want to erase this iPhone and sync with this iTunes library? An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library."appears.
Any assistance would be greatly appreciated.

u can give try to using external enclosre and backup ur files. I hope u will get files back. or using external enclosre with ur hdd boot into Linux and try to mount ur harddisk.
there are multiple no of tutorial to mount apple partion in Linux.

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.

Macbook airport extreem and brother printer/scanner DCP-330C

I have macbook airport extreem and brother printer/scanner DCP-330C and everything works fine.
I can print wireless.
The only thing that irritates me is, when I start my macbook I first see a screen with MFL-ProSuite, I quit then a screen with connect with USB, I quit and then I see a small blue screen.
Is there a way to get rid of these things, so I can start directly with the things I want to do.
Thanks for the reply.
Frank

That is something that has to do with the brother software. Doesn't have anything to do with the airport base station.
I would try and Contact brother to see about disabling it.
What I think , is probably because the printer is on the airport not the computer so brothers software is getting confused.
See about deleting just the software and not the drivers. That is if you dont need the software.

Airport seems to be scanning almost all the time

Hi
I have searched the forum and not sure if my issue is part of a wider software problem. The symptom is that the Airport gives a message on both my iMAc and MacBook Airport:scanning. It then finds the network shows Airport: on but then very quickly starts to scan again. I have 5 bars for signal strength.
So my question is this a problem I have and needs fixing or more general one waiting for Apple?
Thanks

It should only scan when you select the AirPort drop down menu. Anytime you do this it is going to scan for wireless networks in case you want to connect to one that has come online or gone offline since the last scan. That doesn't mean it is always scanning, it just means it is scanning anytime you use the drop down menu. This is normal.

Airport seems to be going out

I have a 3 year old iMac intel processor. Apple Care ran out in April (interestingly, the long thread about the problems I had getting help from Apple Care has been removed). The past month a new problem has started. Airport seems to work for a while and then stop working. I figured out on my own that to turn it off and then back on often works. The problem is this is happening more and more often. Sometimes I spend an hour doing something online that should only take fifteen minutes because I spend so much time turning Airport on and off. Are there any suggestions other than getting a new computer at this point? Thanks.

I usually check because the solutions often depend on the OS.
The first thing I recommend for intermittent WiFi issues is to be sure that the router firmware is up-to-date. Even then some older routers do not seem to play well with Leopard, even though they work with Tiger and PCs. I presume it's a security level thing. I had to update two routers before they worked properly with Leopard.
If your router does not support WPA2, that's a sign that it's too old.
It could also be your computer - or some RF interference or even others in your area using the same channel and interfering with your own WiFi signal.
You can download one of several WiFi apps that can check the signal levels, etc.
One is
istumbler
the other is
APGrapher
they are free Downloads. You can search for them quite easily.

Can't Install My Photoshop 7 again. The setup.exe seems dead.

I can't Install My Photoshop 7 again. The setup.exe file seems dead. The CD looks fine.
I reinstalled a fresh version of Win. XP Pro Sp3 and it wiped out several of my programs so I've been re-installing them. Of course I lost the registry and have to build a new one by reinstalling my programs. But my Photoshop 7 CD seems to have a dead setup.exe file and it will not respond as it used to. I've tried everything including disabling virus program. I don't know what else to do. Maybe I need a new setup.exe file but I have no idea where I could get one.
Yes, I do have a registered product. Can anyone help me?
Thanks, Judi

Thank you so much for your suggestion R_Kelly.
Yes, I had tried copying the contents of the installation disk to both my external Seagate drive and right onto the C: drive, itself, but with no success.
But I just experienced a miracle and it installed like butter - to my utter amazement. I will share my experience in case someone comes along with a similar problem and maybe my situation will help them.
When I installed the "rescue disk" to replace my entire OS on my laptop, the techs had given me some choices in options which I really didn't know how to choose from, and I was a professional IT person in the late 90's. That's where I got into trouble. What I wanted to do was just overwrite my Windows XP Pro SP3, like we could do back in the "old days" when computers were open-source and not all proprietary. When I selected to delete the current Windows partition to make room for the new installation, apparently it also deleted the registry and my computer had no knowledge of the programs I had installed and I had to reinstall just about everything. I thought I was okay with that.
In the process of finally installing the new Windows OS, I was asked to give my computer a "name." Well, I don't recall that I ever gave it a name before and there was no place for me to go to find out. So, I gave it a name "JudiLenova." When I couldn't get my programs to run, I thought that maybe I had not only lost my Registry file but maybe whatever ini files I had left didn't recognize that name, so I changed it to "Judi," still not recalling what, if any, name I had given it before. As I encountered problems with trying to install Photoshop, I looked at my systems directories and saw that there were equal files in two different pathways, one for each name. I wondered if maybe DOS, which can't make decisions, couldn't decide which path was the right one to find files I needed. I sure regretted not using the "repair" option on the rescue disk, but it was too late. I need this computer to operate using all of the tools I have installed on it.
I bought a powerful fixit program recommended by CNET to fix things and it found over 1400 problems, but still nothing fixed this problem.
One thing I had noticed is that sometimes when I would do a restart of the computer, the Windows Installer would suddenly show up to finish the Photoshop install, but then it would stop initializing because of the restart. (So close, and yet so far away!) I knew the old system was long gone and stupidly I had deleted the full backup I had stored on the Seagate, so I looked at the "restore" option to see what setpoints there were to see if maybe I could roll back to an earlier time. The only restore point I had was for the day I had installed the rescue disk. I said "what the heck" and opted to roll it back. When I made that selection, I got the message that the major change would be that the computer name would be changed from "Judi" to "JudiLenova." I thought that might solve some of my problem. Amazingly, it appears to have solved the Photoshop problem because I put the disk back into my D: drive and off she went without a hitch!
My hunch is that DOS couldn't find the Install Shield to enable the installation. Whatever the cause of the miracle, I'm grateful that I didn't toss my computer in the lake outside my window... but it sure was tempting.
Thank you again for your attempts to rescue me. I hope this helps the next guy who comes along. Now I'm going to try to install all the rest of my beloved old Adobe programs and everything else. Fingers crossed!
Judi :-)
