Yosemite 10.10 Wireless Diagnostics WiFi Scan not working

I just upgraded to Yosemite 10.10 and I can't use the WiFi Scan function in Wireless Diagnostics app anymore (my router is a last generation airport extreme).
When I perform a WiFi Scan, Wireless Diagnostics either crashes and quits or the wheel keeps running forever.
Is this a Yosemite known bug?

It used to have a wifi scanner in Mavericks, like this http://letstalk-tech.com/access-wifi-scanner-mac-os-x-mavericks/
But seems like "Utilities" no longer available in Yosemite, anyone knows about why?

After updating to Yosemite 10.10.2, macbook air Wifi does not work. What to do?

I upgraded from Maverick to Yosemite in Nov 2014 & my mack book air 2011 model became slow. Yesterday after downloading & updating 10.10.2, Wifi does not work, it prompted Gatway Time out. Anybody can help please? Dr. Mostafa

Moreover I am to add, in the same network, windows PC Wifi works & more interestingly Macbook with Maverick also connects with the same Wifi, I mean to say this is the problem with Yosemite 10.10.2. Before updating on Sunday last, my Wifi was working nicely.

Wifi does not work correctly on iPad Mini w/ Retina display

I've found that Wifi does not work properly on the iPad mini w/ Retina display.
Some background: I own three iPads (iPad mini w/ retina display, iPad mini, and iPad 3rd gen), an iPod touch 5th gen, and a Macbook Air, and use them all frequently with my pocket Wifi router.
None of them exhibit any Wifi problems whatsoever except for my iPad mini w/ retina display.
Here are the details:
In the middle of using Wifi with my pocket Wifi router, the Wifi connection will abrubptly drop, then reconnect. After the Wifi reconnects, it is no longer able to connect to the internet (even though Wifi itself is connected).
Once the iPad mini w/ retina display's Wifi gets into this state, the following may or may not restore WiFi temporarily:
Restart the device
Reset network settings
Yet, even if connectevitiy is restored, the problem will happen again within minutes.
When the iPad mini w/ retina display gets into this state, the Wifi on my iPod touch, other iPads, and on my Macbook Air work perfectly fine, so I know the problem is not with my Wifi device or it's connection, but specifically with the iPad mini w/ retina display
Note:
The iPad mini w/ retina display never has any issues with my home or work Wifi networks. The problem only happens when connected to my pocket Wifi device. Yet, all of my other iOS devices and my MacBook Air work perfectly with my pocket Wifi device, therefore I know the problem is not with the pocket Wifi device, but with the iPad mini with retina display.
Solutions:
Resetting the iPad mini w/ retina display to factory settings does not solve the problem
Resetting network settings on the iPad mini w/ retina display does not solve the problem
I have even replaced my original iPad mini w/ retina and got a new one. Yet, the new device exhibits the exact same behavior as the original device.
Conclusion:
I know this is not a hardware problem (since it happened with both my original as well as replacement device).
I know this is not a problem with my pocket WiFi router, since it works perfectly with all of my other iOS devices and MacBook Air.
Therefore, this must be a software / firmware bug with the iPad mini w/ retina display. Apple will need to fix this in a future software update.
Has anyone else seen this problem?

I too have experienced this issue over the past two days... I have a 16gb ipad mini retina, for reference. I bought the device one week ago, and had not experience any issues at all until bringing my device to work. I logged into my work's enterprise level wireless network both yesterday and today, maintained normal wifi capabilities for 2-4 hours each day, and was then randomly dropped, both days. I tried hard resets, resetting my network settings, airplane mode, etc. Nothing has worked. I am still offline on my ipad mini retina.
My iPhone 5 is sitting right next to my iPad mini retina. The iPhone is currently connected to the same very network, and has been for the past two years. I have never lost connection on my iPhone's wifi, just my iPad mini retina.
This must be some kind of bug, as it does not sound like a hardware nor network issue.
Hopefully they fix this in 7.1.

Hello again samyak. You are very welcome!
The first device (the virtual adapter) is virtual network which allows you to use the computer as a "software router." Unless you're using this PC as an Access Point this device is useless to you. This article has more information on the service. Your best bet is to just disable it. Try the following.
Click Start, go to "All Programs," and select "Accessories."
Right click on "Command Prompt" and select "Run as Administrator."
Type the command "netsh wlan set hostednetwork [mode=disallow] and press Enter. This should disable the virtual adapter.
Exit Command Prompt, reboot the computer, and verify that the device is no longer listed.
The device with the "ACPI/HPQ0004" ID actually returned two results. The first was the Quick Launch Button software. The other was related to Hard Drive Protection. Try this driver.
Make sure to reboot after all of these instructions have been completed. Then go back to Device Manager and verify whether everything looks as it should.
Continue to have a great day!

iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

X100e - Wireless is on and not working

Hi guys,
I am completely new to the forums and to thinkpads. I have had my think pad for 2 months. Till yesterday everything was working well, until I decided to update the drivers. After it the wireless stoped working. Problem is exactly the same as:
http://forums.lenovo.com/t5/ThinkPad-Edge/Wireless-apparently-active-but-not-working/m-p/280548
However, the solution does not work for me. All my drivers are up to date. I did reinstall the Realtek driver, access connections and updated bios without any luck. Clicking repair does not solve the problem. The wireless is not shut off in the BIOS. Do you guys have anything in mind?
Additional details:
Connection status:       Not connected
Cause:       Association failed - wireless radio not powered on.
Error code:       016
Recommended action:
Communication with access point could not be established because the wireless radio is off. To power on the radio and attempt to connect, click Repair.
If the problem persists, contact your network administrator and provide the troubleshooting information below.

Hello,
A couple of things to try:
Toggle the Wi-Fi radio on and off by pressing the Fn+F5 key combination.
Open the Device Manager (filename: DEVMGMT.MSC), remove the wireless adapter, then reboot and let Windows re-detect it.
Let us know the results of the above, and we can proceed from there.

After upgrade to OSX 10.9.2, my wifi is not working

after I upgraded to OX S 10.9.2, my wifi is not working properly. When I connect to the internet via wifi, the wifi disconnects in seconds.
But if I connect to the internet on my phone, it works.
What can be the problem?

You might:
Try these in order:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

Wireless network and bluetooth not working on touchsmart 600

This has not worked since day 1 and I have been using wired internet.
I really need to setup a home network and need to use wireless.

Everytime I try to download it is seem to be for a notepad... mine is a touchsmart desktop...
Please advise

Hi coffee12345,
Welcome to the HP Forums!
I have read your post on your wireless keyboard and mouse not working with your desktop, and I would be happy to help you! To begin, I need to ask you a few introductory questions:
What is the Product and Model Number of your desktop?
What version of Windows are you using?
Is this a recent issue, or has it been like this since day one?
Are you using a USB hub to connect your peripherals or is it directly plugged into the computer?
Please re-post with the necessary information, and I look forward to your reply!
Regards

I am using chat-r wireless and facetime is not working but when i put rogers fido or any other carrier sim in it work. Anyone know what the problem?

I'm guessing it's a compatibility problem similar to that that T-Mobile in the US has. I'm not familiar with chat-r wireless, but I'm guessing it's not a supported carrier for the iPhone. If they can't tell you how to fix it, I'm guessing it's just plain not going to work.

Wifi Sync not working on iOS 6 and iTunes 10.7 with iPhone 4S

I am running Windows 7 64-bit but WiFi Sync is not working on either my iPhone 4S or my wife's iPhone 4S. Worked fine before upgrading. All settings look correct in iTunes 10.7 and on our iPhones 4S's. Already tried uninstalling iTunes and all associated Apple programs (Bonjour, Apple Mobile Device Support, Apple Application Support, etc) and reinstalling iTunes but no help. Temporarily disabling Norton Firewall did not help. If I hook up either of our two 4S phones via USB wire, they Sync and Backup fine. Just WiFi Sync not working. Can't initiate sync from iPhones because button is ghosted stating it is waiting for PC to be present. Phones don't show up under Devices in iTunes unless hard-wired via USB cable. Any suggestions?

I am getting sync issues too (although on OSX) - seems like others are getting issues too:

My iPod Touch 3rd gen is screwed up the backlights screwed and the Wifi is not working its showing no wifi!

See:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem. A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.
Apple Retail Store - Genius Bar
For backlight
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

My iPHONE 5 wifi is NOT working when am 3 feet away from router while my iPhone 4s has full signal all the time.Please help.

The problem would seem to be in the firewall in your router. Have you tried disabling it? I assume you've updated the router firmware, right? Consider bypassing the ISP provided router (using it as a modem only) and unsing another device such as an Aiport Express.
