MacBook Airport Card Temperature/Speed

Macbook Penryn 2.4 GHz. iStat Pro says 157 F/68 C. Constantly. On the other hand the bottom does not feel that hot at all. Top cover is slightly warm, most of the time I will not even notice. After I disconnect the power adapter and instntly connect it back again, the temp goes down to 130 F/54 C in about 10 sec and gradually in matter of days it will go back up to 155 F and stay there. So I wonder if a) something is wrong with the power inside the MB or b) the sensor is totally messing it up and iStat Pro is reading the wrong info. I don't believe the problem is with the Airport Card. I already replaced 2 MBs on my third one. Still the same thing...AppleCare has no idea why this is happening. I replaced the macboook once. I am not going crazy about that, but I have another MB that I purchased November last year. It is 2.2 GHz and everything elese is exactly the same (i.e. software installed, processes, memory, hdd..). In exactly the same conditions the temp stays at 119F/48C. Additionally the download speed of my new MB (wireless) is at least 2 times slower than my relatively old MB. Tested this on 3 2.4 GHz MBs with the same poor download results. Upload is exactly the same.
Any comments would be appreciated.

Thanks for your input. Just wanted to make sure it is not something out of ordinary. I moved my "old" Santa Rosa 2.2 GHz MB to draft-N and it seems that it runs at much lower temp than Penryn. I have not seen thou the CPU temp to be affected...That's why I am a little bit surprised...My understanding is that there is no Airport Card temp censor and the calculations are hypothetical and NOT precise...

High Airport card temperature

After installing SL my airport card temperature has been running around 153 according to my iStat Pro. This has caused my fan to run 6200rpms and it is really loud. If I turn airport off, everything returns to normal levels. However, this is not a good long-term solution because I need to run airport frequently. Any suggestions as to how to fix my problem? Has anyone else had this problem?

Airport card MTU speed needs to be changed

How do I change the MTU speed on my airport card? Internet hangs and runs slow. Rouert is N1 and support says mtu should ne 1400. Cant figure out how to change it.

I had a similar problem; in the end I got tired of working with terminal because the changes are not permanent. I went Googling and found that the OSX utility application 'Cocktail' allows you to customise MTU settings permanently. There are several applications available, but I settled for the one mentioned. Works like a charm for me. Try it and see if it does for you.

MacBook Airport card has lost its IP address and won't connect to my network

The Airport card on my MacBook has lost its IP address and will not connect to my network. It worked fine until about two or three days ago. Network Diagnostics says that the Airport now has a self-assigned IP number and will not connect to the Internet. I can't find any info anywhere that tells me how to restore the IP number, and I don't get how it can have a self-assigned number and not connect. I have AT&T U-Verse, and my iMac desktop and two iPhone 4s connect with little difficulty. The MacBook is three years old, and AppleCare just expired two months ago. I'm still running 10.6.8 on both machines. I found an article saying that sometimes DHCP leases expire, but my desktop still works ifne, and I've had both connected to the same network since the same time. The artcicle said that more than one machine can share an IP address, so I wanted to try to enter the desktop IP address into the laptop, but I can't find a way to do so, either. Any thoughts?

Have you tried making a New Location for each yet? The Automatic one get confused easily.
Some "nix" to try when it happens also...
sudo ipconfig set en1 BOOTP;sudo ipconfig set en1 DHCP
sudo ifconfig en1 down;sudo ifconfig en1 up
Sometimes having an all OFF Location can help, thanks to Gnarlodious...

My MacBook Airport card has never appeared.

I have a new MacBook. At no time has the airport card made its presence felt. In System Profiler, it says re Airport Card 'No information found'. On Network Port Configurations, Airport is grayed out so is unresponsive.
The MacBook is located adjacent to an active 802.11 Netgear router. An adjacent G5 desktop machine receives strong wireless signals from the same router. The MacBook is able to log onto the Web via a built-in ethernet link to the same router.
According to Apple, Airport is standard on this model, hence my confusion. What advice can you give me? Is there some straightforward set-up procedure that I can follow, to avoid having to return the MacBok to the supplier 130 miles away?
Jonks.

If System Profiler is not showing the Card I fear it may have been jarred lose or just not connected during assembly. It's not like earlier ibooks etc. where you can get to it easily either. Sorry - I think you may have to bring it in.

MacBook Airport card: Where is it?

My daughter's MacBook Airport has ceased to function. One of the trouble shooting recommendations is to re-seat the card but I cannot find where the card is so that I can re-seat it. Does anyone have instructions about how to get to the Airport card?

First of all, thanks, but it does look extremely complicated and I don't think I'll try it.
Lemon and Falk are extraordinary. My favorite Great Race scene is Boracho, although the early sequences of Professor Fate trying to top the Great Leslie are the most hilarious slapstick scenes except possibly Blake's other great character Inspector Jacques Clouseau.
Anyway thanks for the help.

Macbook airport card and antenna

i have 2 macbook c2d,one has the 2 antenna airport card and the wifi is very slow,the other with 3 i presume is n version,but i had to swap the screens over,now the mabook i use has a 3 antenna card but only 2 antenna from the monitor,would i be better of using the 3 antenna version but ust plugging 2 in and which 2?

I can't help with tracking down the "T" shaped antenna that plugs into the back of the G5, or an equivalent, but I can tell you that the wire that connects to the Airport card in my G5 disappears around the back of the motherboard.
It may have a metal ring on the other end but I can't see it.
I'm assuming you didn't buy the G5 new, because you are missing of the "T" shaped antenna which is supplied with the computer, so I'm guessing whoever had the G5 before you pulled the airport card out before disconnecting the antenna cable and ripped it from its mounting.
My guess is the metal ring is used to attach it somehow.

Macbook airport card keeps swapping between airport express stations

Hi
i have set up a network with 4 airport expresses.1 is the WDS main and is connected to the internet, 2 is configured as a relay with no client access, 3 is a client of the relay and is wired for airtunes, 4 is a remote and allows client connections.
Everything works except i noticed constant drop outs on all machines.
I ran AP grapher and i can see that Airport is connecting to 4 remote station with very strong signal and then for no reason switches automatically to the 1 base station and back again after a few minutes. The signal for the base station in ap grapher is -66 vs -39 for the remote station.
why does airport switch like this? Is there a way i can make it lock on the strongest signal or specific mac address?
Thanks for anyone's help.

There are two different versions of Flash, the '''''ActiveX''''' version for IE and the '''Plugin''' version used by most other browsers.
1.Download the Flash Plugin version setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
4. Start Firefox and test your installation here: https://www.adobe.com/software/flash/about/

Can you disable 802.11g and 802.11a on an Airport Card?

Does anyone know if there is a way to disable 802.11a and 802.11g functionality on a MacBook Airport card? I have a very old 802.11b access point and the airport card seems to be making it fail. I was hoping that by turning off 802.11g or potentially adjusting some other airport parameters I might be able to keep the AP from crashing. I'm hoping to keep the AP I have because it has an integrated print server which has been great. If there is no way to modify the settings on the airport card, I guess I'll need to upgrade my AP.
Thanks.
Macbook Mac OS X (10.4.8)

Well, I should have used the advice I give to everyone else. Even though my wireless router is very old, there was a firmware upgrade for it. Even though the release notes for the firmware said nothing about it fixing a problem with a MacBook, I upgraded to the latest firmware. After a week or so of testing, it seems to have resolved the problem with the AP going dead when the MacBook was using it.

Computer froze; after reboot: "No AirPort card installed."

I was online checking email, doing nothing out of the ordinary, when all of a sudden my computer froze. There was no spinning wheel; the computer was completely unresponsive. I manually powered it off, and when I turned it back on and found that I could not connect to the internet. I clicked the AirPort icon and the dropdown said "No AirPort card installed."
I reset the PRAM. I did an SMC reset. I reformatted the hard drive and reinstalled OS X. I did both the standard and extended Apple Hardware Tests and there was "No trouble found."
In System Profiler, under Network > AirPort, the various Software Versions are listed. However, AirPort is not listed under Network > Active Services. In System Preferences > Network, AirPort is "Off" and when I attempt to turn it on, nothing happens. If I delete the AiPort connection and try to add a new one, "AirPort" does not appear in the interface dropdown menu. I tried turning AirPort on via Terminal using the command "sudo ifconfig en1 up" and received the message "ifconfig: interface en1 does not exist".
At this point it seems as though the AirPort card has crapped out, but if it did indeed go bad, why does it not show up in Apple Hardware Test? Does anyone have any suggestions for me?

As I understand it, the SMC and PRAM are actual chips on the logic board, and the resets restore them to their original factory values. That's about all I know to say about them since I'm not an IT person and have very little troubleshooting experience myself.
I'm not familiar with the term NIC. Is this the same as the airport card?
http://www.powerbookmedic.com/13-MacBook-Airport-Card-p-17152.html
If so, it should be easy to locate on the logic board as it's pretty large. I don't know if the same card is used in both of your 13" Macs or not--You would need to research that for yourself. However, it seems like in many cases, replacing the card didn't seem to work, although you could always inspect it to be sure the antenna is well seated. I'm not familiar with the 13" card, but the card in my 17" MBP actually has 2 antennas.
Both PowerBook Medic and ifixit have step by step guides for disassembling Macs and replacing parts. You may be able to find the information you want there.
Just finished looking through the long thread, and it looks like every possible solution that I could think of has been tried.
As for testing the hardware, many people have recommended Tech Tool Pro:
http://www.micromat.com/
You also should have the Apple Hardware test on one of your original system discs, and if you had Applecare, a Tech Tool Deluxe disc with a hardware test. I'm not sure, but it may be that if you purchased Applecare and got Tech Tool Deluxe, you may be able to buy Tech Tool Pro at a discount.
Apple Stores also have a hardware test they can run from their store feed if you have access to one.
If you do decide to resort to a USB card, here's one that works pretty well:

2008 MacBook Pro 17" eats airport cards

I have a 2008 MacBook Pro which was under AppleCare support and had it's AirPort card replaced several times. A few weeks after the support expired, again the last card Apple put in started to fail and soon became unusable. The local apple store refused to help despite the long history them having to replace the card over and over. I bought one on eBay and it was fine for four months and then it too failed.
This is very strange but it seems this unit is somehow burning it's AirPort card. I installed a temperature monitor software and the temps looked fine to me. Could it be overvoltage supplied to the card? I've search online and not found any reports of similar issues with this model.
Symptoms:
1: Networking over AirPort stops working. Turning AirPort off and then back on results in it staying off...will not come back on. Hard restart helps but it fails same way a short time later.
2: The system totally freezes. Cursor stops moving, last sound in progress loops. Game graphics (World of Warcraft) sort of keeps going with animations but the UI is non responsive.
Depsite the temps looking ok to me, my feelign is I have not monitored it to much and do not know what is a valid max temp so, maybe it's cooking them. It did seem like letting it cool off helps though, maybe it is just letting it sit for awhile because sometimes just quick restart helped for a while (minutes).
Makes sense? Should I push Apple to get this fixed? They knew it kept destroying AirPort cards and they never fixed that issue.
Note Apple also replaced the motherboard at one point due to NVIDIA GPU issue. Also they replaced the battery as it was swelling so bad it stopped the trackpad button from working.

I suspect a loose cable in the display connection, try cleaning the ports and reconnect the cables.
you can take this to a shop,
or
if you want to DIY, read this guid carefully.

Do I Need Airport Express If Both My iMac and MacBook Have Airport Cards

Just ordered a new MacBook that has a built-in airport card. Also will be using my good old iMac (both running Leopard 10.5.6). Since both computers have the built-in airport cards, do I still need Airport Express so I can use a WiFi network? I've already set up an Airport WiFi network on my iMac so I can WiFi my iPod touch. Isn't it the same principle? Hate to waste money if I don't have to. Also, I've got another iMac in the house that also has an Airport card (also running 10.5.6). It's in the shop for repair now so I can't try this out to see if it works - but can I simply turn on airport and internet sharing on that mac and let it use the WiFi network already set up on my other mac? Hmmm??? Thanks for any help.

Basically what you have done is utilize OS X's Internet Sharing feature on your iMac. This turns your iMac into a "software" router. In this case, you MacBook (& other wireless clients) can access the Internet through the iMac so you do not need to get a hardware router, like an Express or Extreme base station in order to do so. The only constraint is that the iMac must be on for this to work.

Macbook Pro, accidentally uninstalled airport card somehow. Reinstalled OS and everythng, appears to be software issue, but I don't know what to do.

Dad's Macbook Pro (10.6.3, from 2010) had perfect wifi, he accidentally uninstalled(?) it somehow, has no idea how he did it.
It said "no airport card installed" when I'd click the little wifi icon on the bar, or go into network settings.
I have wiped hard drive, reinstalled OS, reset SMC and PRAM, to no avail, and now there is no wifi icon at all.
I ran a hardware test (both regular and extensive), and nothing is coming up.
It's like the computer just CAN'T use wifi- I can't select it from any menu, for example:
-in the main "Network" window (under System Pref) it shows only Ethernet and Firewire on the side bar
-when I select the "+" to add a service/interface, only Firewire, Ethernet, Bluetooth DUN, VPN, 6 to 4 and PPPoE appear
-in "Network Setup Assistant" only DSL modem, cable modem, LAN are choices. "AirPort" is there, but is grayed out and cannot be selected.
Airport Untility is still installed, and will open but says unable to find any devices.
And when I ran System Profiler, under Network > AirPort, I have the following
"Software Versions:
     Menu Extra: 6.2.1
     Configd plug in: 6.2
     System Profiler: 6.0
     Network Preference: 6.2.1
     AirPort Utility: 5.4.2
     IO80211 Family: 3.1"
I simply don't know what to do. At first I thought I might need a physical "card" replaced, but hardware test says everything is fine, so I feel it must be software, but I wouldn't know what to try besides what I've already tried- I thought reinstalling the OS would do the trick, honestly, but it hasn't. Please help.

System profiler certainly does suppy information of installed hardware. Not sure why you said it doesn't.
If there is no wifi card found in the syetem then the info I outlined would be there.

Airport card no longer found on Macbook

My airport card is no longer being found by my macbook. I haven't done anything different?

i'm having the same problem. was using my macbook (online, no less!) 30 minutes ago, put it to sleep, and then when i opened it up 5 minutes ago it could not find my wireless network. it gave me the message that "no airport card is installed" on my computer.
tried restarting a couple times but nothing changes...also, i can't try to tweak settings in the Internet Connect panel, since the airport option does not come up.
do i have to reinstall the OS, or is this something that should be "naturally" remedied after some more restarts?
