When I bootup my Macbook my family's PCs wifi connections stop working !
Hi everybody, when my nephew boots up his Macbook (Snow Leopard 10.6.5) he can regularly surf the web through a wireless router. However the wifi connection on other devices (Windows Vista notebook PCs, Linux Pcs, Windows 2000 PC, Playstation 3 wireless, PSP, Xbox ecc.) stops working. When he shuts off his Macbook, wifi connection on Windows/Linux PCs etc. starts to work again.
I've had similar issues only with a wireless TV signal transmitter (working at 2.54 GHZ). When it is on, wifi connection is impossible, no matter what channel is selected (it has 4 channels).
What to do with my nephew's Macbook? I can see that every 10 seconds Airport is searching for wireless signals (the wifi led on the router blinks), but no other traffic is sent/received so I don't think it's a bandwidth problem.
Can Airport be shut off and can I connect to wifi router without airport using other apps or using a terminal (console) application (I use Linux and many commands are the same, i.e " iwconfig - ifconfig ")?
Maybe it's the transmitting power of MAcbook wifi device (too strong?). Can it be modified? I'm not a Mac guru... In linux there is a command, say "iwconfig wifi0 txpower 20mW " to tell the wifi driver to use 20 mW transmitting power on wifi0 device. In that Macbook the wifi device is called "en1"...
Many thanks in advance for good ideas..!
Many thanks for such a fast answer!
@ a brody
I have so many wifi devices (at least 17) I don't want to create a MAC address filtering rule for each one of them! I don't ever know if my router can accept filters on so many MAC addresses!! But I will try out your suggestion if I can't solve in other way.. Thank you!
@ J D McIninch
Thank you, I will try... However, my router don't need to be restarted to get online again: when my nephew shuts off his Macbook the wifi connection is all ok. How could it be that a routing table gets corrupted when the Macbook is on, and that very same routing table gets repaired as soon as the Macbook is shut down? I'm sure, however, my router is a pre-N one ( Belkin modem/router bought in 2004, 802.11 b/g 54Mb with 125Mb turbo mode feature always turned off for backward wifi compatibility)
Thanks

A magnet fell on my macbook "late 2007 series black" and it stopped working. When i start my macbook up it sits on the white screen. i tried inserting the snow leopard disk to do a clean install but the disk ejects and all i see is the pointer. i even bought a new hard drive to do the clean install but the same thing happens. Please Help
Your problem is not Boot Camp, in fact, is your optical drive. Win XP requires indeed sp2, but also the internal drive, does not work from external optical drive.
For other possible tricks, please use the appropriate Boot Camp forum, not here. Mac OS X may be installed from both external and internal optical drive and/or internal/external partition of a disk, any disk. Windows is not so generous. -
my MacBook Pro is crashing and Mac OS stops working sometimes so I have to restart it. And sometimes it stays on the first white-ish screen with the Apple and won't start further.
What to do?
Does that mean that the is the end of my Mac Book 5bought in the summer of 2009) ? Or is there someting to do to fix it?
Thanks
VTry this:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update. -
Hi, I've used four different Groups when emailing for the past few years, and suddenly they have stopped working. I've tried creating new Groups but that doesn't work either. I haven't changed or done anything different and it is driving me mad......can anyone help, please?!
Thanks for that information!
I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?! -

MacBook 2008 wifi suddenly stopped working and says no wifi hardware. Took it to an apple shop, they said it could be the airport card but wouldn't do anymore then that.
Any help on how to fix this? How do I know if it is the airport card or not?
is there anything else I can try first?
thanksIf the technician at the shop is competent, he has given you a diagnosis that should have identified the problem. You could run the Apple Hardware Test to verify the findings:
https://support.apple.com/en-us/HT201257
Note the Apple Hardware Test is not definitive.
Go to the iFixit.com and Powerbookmedic.com web sites. They have parts and installation instructions. To install an Airport card is fairly easy.

iTunes keeps shutting down when I open it up. The message says iTunes has stopped working. A problem has caused the program to stop working correctly. Windows will close the program and notify you if a solutions is found.
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you've already tried something like the above then try opening iTunes in safe mode (press and hold down CTRL+SHIFT as you start iTunes) then going to Edit > Preferences > Store and turning off Show iTunes in the Cloud Purchases. You may find that iTunes opens normally now.

Remote Desktop Connection Stopped Working when Disconnecting
Hi I have a fresh clean install of Windows 8.1. Whenever I RDP into another Windows 8 machine... upong disconnecting I get the error: "Remote Desktop Connection Stopped Working"
I have tried not mapping to remote printers, or drives (smart cards etc.) and it still persists. When I remote to Windows Server or Win 7, it does not happen.
Anyone have any ideas?
Thank you
miFYI, same issue here, Windows 8.1 on ThinkPad W520 (upgraded from Windows 8).
Even without Fingerprint Manager, and having uninstalled ThinkVantage Password Manager as well, still crashes. I also tried the:
Dism /Online /Cleanup-Image /RestoreHealth
but no luck, my mstsc.exe is still crashing when the remote session window is closed.
Any ideas? Happy to upload/provide more details, here's the Report.wer contents from

Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.

When I don't use my iphone, my wifi connection stops
since a few days my wifi connection stops when I don't use my Iphone. So when someone send me a messag with whatsapp I don't receive it untill I turn on, use my iphone back. What do I have to do so that my wifi is always on? I did'nt change anything on my Iphone, but it does'nt work since a few days.
I just don't understand one thing. Before last week I had no problems about it (I had wifi all the time, even when I did'nt use my iphone, and now (when I came back from holiday) it does'nt go anymore. So buying a iphone wasn't a good idea. I have wifi, but if I don't use my iphone it is not possibel to reach me because the wifi falls off.
I understand that it is for saving the battery. But I still don't understand that it stops working (my wifi).
