Wireless card deadlocking computer

*TL;DR summary:* high airport card usage results in a deadlock of my mbpro after a few minutes, not even disk access works. This always ends in me holding down the power button for 5 seconds to force restart.
Description
Starting about 3 months ago my Macbook Pro would lose internet connectivity and slowly all applications would end up freezing, forcing me to hold the power button to shut it down.
Looking further into the issue, I would notice that usually during high wireless card usage (streaming audio, downloading files for extended periods of time, etc) the Upload/Download rate on my iStat Menus would instantly drop to 0. Firefox would end up with "server not found" and streaming music would stop playing.
While trying to save my work to disk, I noticed that even writing to disk would not work (any open application would hang when I save a file to disk). Clicking anything on the menu bar usually responds, EXCEPT when I click the Airport menu. After the connection stops, clicking the Wireless Networks icon in the top menu would result in the colored spinning icon and then begins the domino effect lockup.
Finder becomes unresponsive (except sometimes the shutdown menu would appear when clicking the power button, but clicking shutdown does nothing). Every open application would not shut down (still active in the dock).
It ends up with me having to hold the power button down and restarting the computer, losing all my work. This is quite annoying and I am out of my AppleCare warranty. Is this a hardware or software issue? Does anyone have any suggestions as this is ruining my Apple Experience!!
Strangely, if I do not use the wireless card much (e.g. plain web browsing) I have no problems.
Thank you,
Jason

That disk is pretty full and may be causing your problems. Anything over 75% full can do this.
Odd, though, that it works when wired.
Have you taken it in and had an Apple Genius look at it?

I need a wireless option for older Mac desktop is there a good card or adapter I want to transfer hd video files over the internet. using a hotspot and wireless card in computer, any recommendations

Is there a good card I can put in the computer, and use with a hotspot? Any experience with uploading HD video files this way. DSL hard wired connection is too slow

As for the people on eBay, my only beef with them is that it has turned into a money hungry store instead of an auction place to pick things up inexpensively, like it used to be.
Agreed.
There is one, in particular, who really puts a dear price on his flashed cards.
Not a friend to the Mac community.
Of course, others see his prices, and say "Well, if he can, then so can I".....
By the way, I have been noticing the same cards, only for PC for around $30-$40, which lead me to believe that those are the ones they are "flashing". Sorry if that's incorrect.
It's OK.
I watch for the prime cards all the time.
Radeon 9800 Pro and XT PC cards have increased to the $50-$70 range.
Pros used to be $20-$30, XTs $30-$60.
Some guys here in Japan are trying to get $100 for Radeon 9800 Pro cards- vanilla PC versions.
The glut in Mac options has inflated the flashable PC card market dramatically.....
The Mac Edition Pro retailed for $200+.
$100 isn't bad for that card flashed to Mac... the XT gets $20-$50 more.
Try telling a PC guy that a Radeon 9800 is a $100 card..... the old boys laugh!
Adding to this is the recent influx of "new" Mac users, PC modders/users buying cheap, used G4's, and the demand for upgrades has increased as supply decreased.
If you see any rev 5.70 Geforce 7800 GS AGP cards, or any FireGl (Radeon) X800XT (unflashed) cards for less than $130, amazing is all that I have to say.
$30-$40, and I'll take 20 of each- cash!
Hmm, same goes for Geforce 6800 Ultra's......
I am just a little (or a lot) frustrated with Apple and Apple vendors lately. For obvious and not so obvious reasons. Please accept my apologies as I go through this phase.
We all have our days, and our reasons. At least, I know I do......
Apology warmly accepted!
Count me as frustrated, as well.
The new machines sure look nice, but when I tally up the price of the software that I own, which can't be run on Intel or 10.6x Macs, my room full of G4's look a lot nicer.

Dv9810us after recovery windows will not detect the wireless card that is bulit into the computer.

After running the recovery (Vista 32) from the recovery partition my computer no longer sees the Wifi card installed.
There is nothing in device manager, the hp wireless wizard doesn't detect anything. I went to HP's site and download the 3 different wifi drivers that it would be and installed them. I can not rememeber what the adapter was.,. thats a problem.
This system was a refurbed unit when I bought it, if the salesman was correct it was recalled because of a faulty Wireless card. I wonder if they replaced the card with one that the restore partition installation could not detect.
Any ideas?

first make sure the wifi is turned on either by a switch located on the front of keyboard or a soft touch icon near the display.. if you have the soft touch make sure it's blue in color if its orange its turned off

Wireless card in my computer?

Does my desktop computer HP Pro 3500 Core i5 3470 have a wireless card and if not, what do you recommend so that I can have wireless?

Hi,
No, as from its specs:
      http://www.cnet.com/products/hp-pro-3500-core-i5-3470-3-2-ghz-monitor-none-series/specs/
It only has:
Networking
Type: integrated
Ethernet Controller: Realtek RTL8171E
Data Link Protocol: Ethernet, Fast Ethernet, Gigabit Ethernet
It also has:
2 (total) / 1 (free) x DIMM 240-pin
3 (total) / 3 (free) x PCIe x1
1 (total) / 1 (free) x PCIe x16
1 (total) / 0 (free) x CPU
1 (total) / 1 (free) x PCIe Mini Card
You can use PCIe wireless card or PCIe wireless card. My suggetion use PCIe wireless card because easy to get the antena work. The following links show few examples:

Connecting a PC with an external wireless card

I have an iMac and am connected wirelessly to the Internet through the Airport Extreme. My roommate has a new Dell Laptop with Windows XP and has been connected through ethernet to the base station. She just recently purchased an external wireless card, and we can't seem to get her connected wirelessly. When searching for available networks to join on her computer, it recognizes my network and says that it has an excellent signal, but when we type in the WEP, it doesn't do anything. It does not give us an error, and it does not connect. Any idea what we are doing wrong and what we can do to fix it?

I still can't figure it out. I unchecked the option that says "enable encryption (using WEP)" and she was immediately connected. I don't think I have a huge problem leaving the network up without a password, I'm in a small residential area. Does that just mean that neighbors would be able to connect? How far does the signal generally travel? And is there any way to see the IP addresses of people connected to this specific network?

G500 Driver_Power_State_Failure problem most likely related to Wireless Card

I recently upgraded my Lenovo G500 laptop to 8.1.
After that, I've been constantly getting BSOD every time I modify some settings on my WIreless card (Broadcom 802.11n Network Adapter). For instance, changing my MAC under the"Locally Administered MAC Address" causes the Wireless configuration window to stop responding, then my wireless adapter becomes permanently disabled (I try to enable it and it says that it is enabling but the adapter remains faded out and locked in a disabled state) unless I restart or power down my laptop. If I restart, the laptop hangs for 3-5 minutes and then a BSOD comes up and suggests that I look online for DRIVER_POWER_STATE_FAILURE.
I have updated the adapter as well as most, if not all outdated drivers on my laptop with the 8.1 drivers offered on Lenovo's support pages (This includes power management, BIOS, LAN, Audio, etc.). Even attempting to voluntarily disable my wireless card causes the BSOD.
As long as I don't touch/modify such settings, I have wireless internet and all seems fine but once I do what I stated above, my laptop crashes with a BSOD. I have looked up and searched about such a BSOD but my laptop has zero problems when I put it to sleep or wake it up. My laptop functions practically flawless except for when changing/modifying settings on my wireless card.
For instance, on Whocrashed.exe:

I ran SFC /scannow and it did detect corrupted files but that has been resolved using the Restorehealth command prompt. I have tried booting to safe mode, uninstalling the adapter and then updating straight to the most current 8.1 driver and that still causes the BSOD.
I'm almost certain that my wireless card probably is defective, or the laptop is defective. I'm still under warranty but I'm hoping to fix this issue before resorting to what I deem as last resorts of factory restoring the laptop or calling Lenovo support.
I am also providing minidumps, driver lists and a whole ton of useful information on my Skydrive:
http://sdrv.ms/17OIYda
Any suggestions or help on this matter would be greatly appreciated as I feel like I've exhausted all other methods.
Moderator Note; subject edited; system type added

"If I restart, the laptop hangs for 3-5 minutes and then a BSOD comes up and suggests that I look online for DRIVER_POWER_STATE_FAILURE."
I had the exact same problem on a Thinkpad Helix after upgrading to Windows 8.1, although I do not know if it was in anyway related to the wireless hardware as you described. However, I noted that in the Device Manager many wireless hardware components had been highlighted with an exclamation mark since the problem had occured (e.g. Bluetooth, Geolocation, Broadband). Here is how I fixed it:
1. I went to System Settings / Device Manager.
2. Disabled all devices that were highlighted with an exclamation mark. I noted that the Device Manager would not respond after disabling so I closed it and then chose to not wait (i.e. forced the Device Manager to close).
3. Repeated step (2.) until all devices highlighted with an exclamation mark were disabled.
4. Restarted the laptop (I don't know if I had to force the shut down via power off at that time, but it may be necessary or you wait for the BSOD).
5. Repeated step (1.) and uninstalled all the drivers of the devices disabled in steps (2.) to (3.), enabling the option to remove the driver from the system, where possible.
6. Restarted the system. This time the shutdown should only take a few seconds.
So far, everything works fine again and I cannot identify any limitations through the disabling and uninstalling of devices (esp. wireless devices do work flawlessly).
Hope this works for some of you guys out there as well. Let me know.
Good luck!

Can't change MAC address of my wireless card on Windows XP

Dear Forum Members,
I have recently bought a notebook, Lenovo IdeaPad G550L (I haven't found section for the G series here on the forum) and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly changed MAC address. I installed the recommended driver, available from Lenovo's website, version 5.10.38.14. I tried the common way to change the MAC address, went to Control Panel -> Network Interfaces -> Broadcom Wireless Network Adapter -> Configure... -> Advanced -> Locally administered MAC address, and changed it to a different address (without ":" or any separator characters). Unfortunately this common solution won't work at all. Although, no error messages are produced when changing it (so it seems successful) my wireless router shows me the original MAC address of my integrated wifi card. Tried to restart my computer, my router, everything.
* Tried different drivers, downloaded a driver from HP which had a separate wireless configurator, Broadcom Wireless Utility. It worked like the driver from Lenovo (except this one hasn't got the utility), but I was still unable to change my MAC address.
* Tried a different driver from SoftPedia, version 5.10.79.14 (this is newer than Lenovo's), it didn't work either.
* Tried Nathan True's MACShift utility. It seemed to change the MAC address, but my router showed the original, so it didn't.
* Tried to look for official Broadcom drivers on www.broadcom.com but found nothing for BCM4310.
* Finally, I booted my alternative OS, the latest Ubuntu Linux, and used the kernel driver b43 for my wireless adapter. I tried to change my MAC address using the command ifconfig wlan0 hw ether .... and connected to my network. It worked, my router showed the changed MAC so the hardware (or the firmware) is capable of doing this by the right driver/firmware.
I tried to address Broadcom with the issue, sent them a letter like this post they replied that they are not competent, they wrote the following (I guess this was an automatically generated message because it got back in 10 seconds ) from [email protected]:
"As the chipset supplier, Broadcom provides driver support to our customers - the manufacturers of wireless devices - that ultimately provide products to end customers, such as wireless LAN vendors, cable modem vendors, and notebook providers. It is up to these manufacturers to provide product-specific drivers and software support to their end customers. Please contact the manufacturer of your wireless device for their current drivers"
Then I addressed Lenovo with the problem, their answer:
"Dear ******,
Thank you for contacting Lenovo, the makers of ThinkPad and ThinkCentre products. As I understand, you have purchased a Lenovo IdeaPad G550L and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly change MAC address.and you would like to know is there an official driver for Windows XP that allows you this basic feature like b43 in Linux. We apologize,Please do speak with our Idea pad technical Team at 877-453-6686 Option 1-2-1-2 for further assistance.
If you have further questions or concerns, please feel free to contact us at 866-42-THINK (84465) option number 2. We will be happy to assist at that time.
Once again, thank you for contacting Lenovo.
Sincerely,
Lenovo Websales/CustServe"
So this means I should call them and spend extra money for phone bill of international calls because of their fault of providing a basic feature that is to be expected from every single wireless card in the market. Should I believe that a guide over the phone is more efficient than a step-by-step solution or a link to an alternative driver? I'm getting kind of disappointed. At least they have understood (or copy-pasted) my problem, dutch comfort though.
Any ideas? Anyone experienced the same problem and solved it? Is there an official (or even unofficial) driver for this device for Windows XP that allows me this basic feature (like b43 in Linux)?
Thanks in advance,
str4ngS

Yes, I have posted this thread to different forums after I realized that Lenovo "customer care" is not likely to help me out and even wirelessforums.org members couldn't come up with any ideas for days, that's why. I have already written that helper applications like SMAC (or etherchange or macshift) don't work, because they do the same thing in the system as I change it in the driver panel, so they use the same method which simply does not work.
Locked? Definitely not. If yes, why can I change the MAC of my adapter under Ubuntu Linux using b43 open-source driver if it's really locked? Or you mean it's locked from software, because Lenovo or Broadcom didn't want their users to change their MACs or they just forgot to release a fully-functional driver? Well, then I would like to have a driver in which it's not locked, because this is a basic feature of my adapter of which the hardware is capable.
I have already contacted Broadcom, see their (automatically-generated) answer in my initial post, but I will try to do that again with more foresight.

Snow Leopard and my alltel wireless card do not get along.

I recently purchased an alltel wireless card for my MacBook that connects to the internet fine, but appears to be messing with the operating system . . . or something. Alltel said they write their software according to the information they received from Apple. Apple says they send the operating system to Alltel, and they have no way to fix my problem. Can anyone out there help me?
It seems that if I shut down my MacBook after every time I use the card, I am OK.
If I use it more than once without shutting down, things start to go wrong. For example, sometimes the keyboard stops working. The mouse is fine.
More often, I disconnect from the Quicklink (alltel) software, pull the card, only it seems the software has not truly disconnected, as the Menu Bar ceases to work, the colored wheel spins and spins, and I cannot shut down my MacBook, not even w/the "3 magic keys," unless I press the power button. A complete shutoff always solves any problems.
I did check Disk Utility and found that many disk permissions did not match and repaired them. This did not fix the problem.
My local Mac "fixer" said she had the same problem with another customer and had to re-install the operating system, etc., etc., but would have to charge me a minimum of $70. She has no idea why this worked or if it will work with my MacBook. I do not want to spend $70 with no guarantee, or even probability, that the problem will be solved.
Any ideas?

Hi Voodooflea, I have experienced exactly the same problem as you describe here. The solution I found was to simply NOT use the QuickLink Mobile software to connect. Rather, just go into your System Preferences and then to the Network section. If it isn't already there, create a new connection with the modem, putting in the appropriate numbers for the telephone and account name. Then, connect from within the Network system preferences and you probably won't have the lock-up of your computer. It seems that I only have this problem when I use the QuickLink Mobile software to connect. Let us know if this works for you.

Can't create a wireless network without a wireless card on my Mac

Help!
O.k. I tried searching the forums for an answer but the odd nature of my problem, and the immense database of topics made it very difficult to find a similar post.
The general issue/idea:
Run a wireless network using Airport Extreme - Connect desktop mac via ethernet and Roku player via wi-fi. Can't get the desktop mac to connect via ethernet when I restart the network/Airport Extreme.
My Father in law has my old computer; It's a PowerMac G5 (Dual 1.8GHz CPUs) running OS 10.5.8), connected to internet via cable (TimeWarner) modem. It does NOT have an Airport or Airport Extreme card installed. The computer works fine, and I don't believe that I 'need' an Airport Card in order to use the Airport Extreme (it's a brand new/refurbished model) in the manner described below.
I would like to use the Airport Extreme to generate/run a wireless network (Do I need an Airport Card in order to generate/run a wireless network? Doesn't the AE actually do that?), connect the desktop Mac to the network via Ethernet (I shouldn't need an Airport Card to do that, should I?) and connect a 'Roku Player (802.11g capable) to the network via wi-fi.
As far as I know, this should be possible.
Basic steps/as I understand them:
A. Connect ethernet from cable modem to AE.
B. Connect ethernet from AE to desktop Mac.
C. Create the wireless network using desktop Mac and Airport Utility.
D. Restart AE to start the wireless network running.
E. Connect Roku to wireless network over wi-fi.
I have no problems with A & B. Once the AE is connected to the desktop Mac, I'm able to get internet via ethernet as it passes through the AE. I can then create a wireless network (step C.) using the Airport Utility (and setup assistant). The problem starts after I've configured the wireless network.
Once I've configured the wireless network, the Airport Utility software prompts me to restart the AE in order to start the wireless network.
As soon as I restart the AE, my desktop Mac tries to connect to the 'wireless' network, even though it's already connected via ethernet. I don't have a wireless card in the Mac, and I don't want to connect the desktop using wi-fi/wireless. It's connected via ethernet, works fine during configuration, and I don't ever anticipate a desire to connect the desktop via wi-fi.
No matter what I do, I can't get the desktop to connect via ethernet. The only network connection option I'm offered is 'Rescan'. O.k. the desktop can't find the wireless network (because it doesn't have a wireless card), and I'm unable to continue with the Airport Utility. I can't make any further changes to the network (the options to manually change the network configuration are not available as the desktop Mac cannot currently talk to the AE - It's still trying to connect wirelessly), and the desktop has no internet connection as it's trying to connect wirelessly.
*How can I...*
*Setup/run a wireless network, while keeping the desktop Mac connected via ethernet?*
I'm perfectly willing to factory reset the AE and start over.
Any help appreciated.
Thwarted by the network.
- Robert

My Father in law has my old computer; It's a PowerMac G5 (Dual 1.8GHz CPUs) running OS 10.5.8), connected to internet via cable (TimeWarner) modem. It does NOT have an Airport or Airport Extreme card installed. The computer works fine, and I don't believe that I 'need' an Airport Card in order to use the Airport Extreme (it's a brand new/refurbished model) in the manner described below.
That is correct, you could connect the PowerMac G5, via Ethernet, to the AirPort Extreme Base Station (AEBS) or any other wired router for Internet access. You do NOT need an AirPort Card for wired access ... ONLY if you want the G5 to connect to a wireless network.
I would like to use the Airport Extreme to generate/run a wireless network (Do I need an Airport Card in order to generate/run a wireless network? Doesn't the AE actually do that?)
That is correct, the AEBS is a wireless router that can provide a wireless network. The AirPort Card, on the other hand is a wireless adapter used to allow a Mac to connect to a wireless network, created by any wireless router ... not just those provided by Apple.
As far as I know, this should be possible.
Basic steps/as I understand them:
A. Connect ethernet from cable modem to AE.
B. Connect ethernet from AE to desktop Mac.
C. Create the wireless network using desktop Mac and Airport Utility.
D. Restart AE to start the wireless network running.
E. Connect Roku to wireless network over wi-fi.
Yes, these are all good assumptions.
As soon as I restart the AE, my desktop Mac tries to connect to the 'wireless' network, even though it's already connected via ethernet. I don't have a wireless card in the Mac, and I don't want to connect the desktop using wi-fi/wireless.
Do you actually have an AirPort Card installed in the G5 now? If so, then it might be possible that the "firing order" for network connectivity has AirPort at the top of the list under System Preferences > Network. Just change the order to have Ethernet at the top and disable AirPort to ensure that the G5 connects by Ethernet only.

Wireless card seems to be not working

Hello everyone,
I haven't had any problems with my wireless card for my Macbook Pro since I purchased it, but something seems to be acting up now. Here's the situation...I went away for the weekend, took my laptop with me, didn't use the internet at all. Then I came back to my wireless card not working. It has a self-assigned IP address of 169.254.183.17. I did some reading on it and what people of said is that when you have this particular address your computer can't access the internet. I have power cycled both the router and modem correctly without any success.
I have another laptop that is windows based that can connect wirelessly so I've identified that it isn't a router problem. The thing that baffles me is that I can hard wire my Macbook into the router and achieve a connection...any suggestions on what I should try next?
Thanks in advance.

Thanks for replying,
I did go into advanced settings to see what was up. And the TCP/IP tab was the area that I was focusing on. Okay...I did try renewing the DHCP lease and it keeps giving me the unusable IP address. One potential problem that may be contributing to this fiasco is that I think the modem in my household is also a router (which we're just using as a modem). The modem isn't mine so I'm not sure how it was setup. I don't believe that modem is activated to give off a wireless connection. I don't know why it would be a problem because I was connecting to the router just fine before. If the windows based laptop can connect just fine, it wouldn't be the router...(just thinking out loud here).
I was given an option by one of our IT personal at the office that I work at...he said that I could completely remove the network from my saved list and re-enter it. He also said that I would have to delete some temporary files that are saved in a hidden folder that are "preference" files for that specific network. I wasn't able to find that folder, and I did try deleting the network but it didn't seem to fix the situation. If I could simply just go back to square one, as I did when I first connected to the network I'm sure it would fix everything.
I hope this wasn't too long to read, hopefully it gives good insight.
Regards

Intel Wireless Card doesn't work with Linksys?

My wired computer works great with the WRT54GX2, but my wireless cannot hold a signal for very long. Support says they can't help me because I have a Intel wireless card. Intel does not support for that card anymore and I can't see where to buy a Linksys card. Please, help.

MBP having Kernel Panic (Crash) all the time due to Wireless card firmware.

Hi all,
I am desperately needing helps from the experts here now. I have the latest santa rosa Macbook Pro. It has been crashing on me lately due to the wireless card firmware. I have run all the latest updates from software update including the AirPort.Atheros firmware update. I have tried to reformat the hard drive and installed a fresh and clean Mac OSX. The crash still persists before AND after the AirPort.Atheros firmware update. I mean I was not having this issue when I first bought the computer while others were whining all over the internet about this problem. When the fix came out, everyone
s problems seem to be solved but my problem arose . A recent Kernel panic crash log is as following:

A way to know that the crash is gonna happen is that the internet stops working and as long as I click on the wifi icon on the menu bar, The crash occurs. Could someone please help to put me out of misery please . Thank you so much for reading this and any suggestions are greatly appreciated.
Thank you
Have a nice day.

i would try this in a test user to see if the issue occurs (more than likely it will)also i would reset the smc and the pram
(test user) go to the apple then system preferences then accounts then in the bottom right hand corner you will see there is a lock click it and put in the password for the computer then click ok then click the plus sign and create the test user make sure that you check the box that says allow user to admin the account then click create account (if a message says something about automatic login click keep) then click the apple and log out then login to the other user.
(smc) you shut the computer down then you unplugg all the cables from the computer then you take the battery out with the battery out you hold the power button down for five seconds then you put the battery back then plug in the ac adapter then start the comptuer up and then plug everything else back in
(pram) you restart the computer holding down the apple option P and R keys till you hear the start up chime twice
if that does not work i would boot to the install disk one holding c and then click utilites from the top and select the mac hd and then verify disk and repair disk
if the issue still occurs then i would back all of the information on the computer up and erase and install
hope this helps

Where can I find a wireless card for my early 2009 Mac Pro (MB871LL/A, MacPro4,1)?

Where on on earth can I purchase a wireless card for my Mac Pro?
Apple is of no help. Their "Geniuses" told me that it is impossible for them sell one to me because Apple will not supply wireless cards or memory for previous generation computers. That is totally absurd. If I want to get a wireless card for my 2 year young computer I can't? I have to buy a brand new computer with one previously installed. Ridiculous!
Any help or suggestions would be of great value to me.

Well I found what I think is the correct card on B&H.
Hopefully it works....

I have a 2009 Mac mini and the wireless card has never worked, would I be able to cover it with my three year extended warranty?

If you mean AppleCare, then I would believe the answer will be yes.
First make sure you have a full backup of everything on your Mac, then run, don't walk to your nearest Apple store.
Note: Due to your Mac now being in computer years, somewhat elderly, Apple may not have the require parts in stock. This will either mean you might have to leave it with them for a number of days, or maybe they will offer you a new Mac mini. While a new Mac mini (if offered) might be a welcome possibility be aware that the new Mac mini no longer has a CD/DVD drive and it comes with Mac OS X Lion and as a result might not run some of your old software.

Wrt54g as a wireless card

I have a wrt54g running my wireless network, can i use another wrt54g as a wireless reciever to add another computer to my system?

No.. You just need to get an extra wireless adapter, it can PCI/USB wireless adapter for desktop computer user or wireless PCMCIA card/USB wireless adapter for laptop user (check first, most likely there is built-in wireless adapter on laptop).
