NB520 - Wifi stopped working suddenly on its own

Hi,
I bought my NB520 in Singapore.
The WIFI was working properly for almost 3 years until recently I have this strange problem.
It stopped working suddenly on its own last June for almost 2 weeks.
Just when I was about to send it to the repair centre, it came back on again.
But the WIFI comes on and off for a few more weeks before it stabalised.
It works ok ever since, until 3 days ago it went off again like the last time.
Usually, when I switch on the netbook, the WIFI indicator (red light) will come on within seconds.
To use Bluetooth, I just right click on the Bluetooth icon and press "Enable Bluetooth Function" and Bluetooth will turn on.
But now when I do that, it tells me to "Plug in Bluetooth device".
Is this a hardware or software problem ?
I spoke with a local technician but she is unsure too.
Would appreciate if you can help me with this problem. Thanks in advance.
Regards,
Fionna

> Is this a hardware or software problem ?
This can be answered very easily recovering the notebook back to factory settings.
But I guess this is not an option for you at this time. Isnt it?
However, the issue you are talking in your post looks like the WLan isnt enabled and chosen properly.
Usually you can use the FN + F8 key combination to enable and disable the WLan and BT module.
Pressing both keys would switch between WLan and BT as well as disable and enable the modules.
Did you test this in the past?
In case the FN + F8 would not work as it should, I would recommend you to download the Wlan driver from Toshiba page released for this notebook series and to reinstall the Wlan driver.
Your feedback would be greatly appreciated.

Wifi stopped working suddenly

wifi stopped working suddenly? and will not turn on in system preferances
Under the Advanced wi-fi Address: 00:00:00:00:00:00
Just clicked on the wi-fi symbol on top bar (sorry do not know name of bar, if some else dose?) and it states that No Hardware installed
Any help please.

I can add my macbook pro to the list of 'wifi: no hardware installed' victims.
At the London Regent Street Store yesterday (after an hour's wait beyond appointment time) the Genius test said it was a hardware fault and the airport card must be faulty/dead. However, when I got home I turned the mbp on and, as if by magic, wifi was working normally. About 3 hours later it failed. I switched off overnight. It's been dead most of the day so I did a complete clean up using Onyx, restarted and, yes, you guessed it, wifi was back.
I guess it could be a faulty airport card but it seemsthere are an awful lot of airport cards failing all at the same time! Coincidence or a software glitch post 10.7.2? Various forums now seem to have plenty of entries from mac owners with this same problem.
How do we get an official response from Apple on this? In my experience Apple are fantastic at addressing this kind of issue once they know. How can we ensure they are aware?

I own a HP Pavilion dv6915nr, it stopped working suddenly.

Hello,
HP Pavilion dv6915nr.
Windows Vista home premium 32-bit.
I own a HP Pavilion dv6915nr, it stopped working suddenly last night. It was working perfectly, I was watching a video on HULU and I stepped away for 2 or 3 minutes, when I came back the screen was off. The laptop seemed to be on sleep, but when I tried to use it again it didn't do anything. When I try to turn it on the keyboard lights turn on for about 2 seconds, then it goes completely off and there is a faint cracking sound on the speaker bar.
I already tried taking the batteries off and using the AC/DC adapter only, it did not work. When I plug-in the AC/DC adapter the light around the power connector turns on.
Hope someone could help me. Thanks.

Try a hard reset, works sometimes.Disconnect all external devices first.
1-remove power cord and battery
2-press power button for 30 seconds
3-reinstall only power cord for first startup.
4-power on
******Clicking the Thumbs-Up button is a way to say -Thanks!.******

I have iPhone 4s, after i updated my software to 7.0.4 my wifi stopped working. The wifi icon at the top is gone. Its annoying that i have to us my data all the time. I've tried the network reset, it didn't work. My phone works fine, just a lilttle bit slow before i upadated to 7.0.4. And now not only the wifi, the phone itself is slower than ever. I wish i didn't udgrade to iOs 7. There's too much problems. There's this one time that I can't send iMessage at all.

Hi s.kouris,
I'm afraid that unless you are able to contact the previous owner and have him wipe the device, or provide you with his Apple ID password so you can delete the iCloud account, you are out of luck.
With iOS 7, an Activiation Lock was added to deter thieves. This lock prevents anyone but the owner of the device from deleting the iCloud account and restoring the device:

Unless you are able to reach the original owner and get the device wiped or the iCloud account deleted, you are stuck with a brick.

When I connect my External HD my WiFi stops working.

When I connect my External HD my WiFi stops working. Anyone knows why?????

I do have the same problem with my MBP 15" (late 2013) on the right USB-Port as well. It still works when I use the left one.
As the external hard drive has its own power source I suggest it doesn't have anything to do with the difference regarding the provided power of the right and left side...(?)
Is this problem solved yet?

Wifi stops working when NTP sync occurs

Every few days I have a problem where the WiFi stops working on my time capsule running v7.6.3. All of the cleints in the house (Mac Mini, two Macbook Pros, iPad, two iPhones) stop simultanously and don't see the wifi network at all.
At that point I get an Ethernet cable and check out the logs. Frequently I see a message similar to the following:
Nov 29 18:21:13
Severity:5
Clock synchronized to network time server time.apple.com (adjusted +810754969 seconds).
Nov 29 15:21:12
Severity:5
Clock synchronized to network time server time.apple.com (adjusted +811604500 seconds).
There are plenty of log entries where NTP sync is successful. I have an Airport Express running 7.6.3 that uses time.apple.com and this is never a problem, only on my time capsule.
I've performed a factory reset twice and it doesn't help. Today I've switched the NTP server to 'us.pool.ntp.org' to see what happens. I also notice that when I power cycle it, the time reverts to January (year unknown) until a sync occurs.
Has anyone else ever seen this? I have an OG 1st gen Time Capusle.

No its new to me bcoz no matter u move latop anywhere up,down,tilt anything shouldnt happen at all,i move mine all directions without loss if this continue to u better go to apple to test sound like interfering inside no idea of this,u cant keep doin restart all the time....its not right........

@Keith:
Why are you always proposing your 'further questions' as answers? That's not adequate in any way!
Especially as a 'Moderator' you should know better, I really dislike this and I am quite sure that I am not on my own with this opinion.
http://social.technet.microsoft.com/wiki/contents/articles/4865.whether-or-not-you-should-self-propose-an-answer-in-an-msdn-or-technet-forum.aspx
It is pretty obvious from the post that this happens while loading WinPE, what is there to misinterpret?
Are you using different WDS servers for your sites?
If yes, try to remove the boot image from the 'Broken' one and re-import it.
Comparing checksums is never a bad idea in such a scenario.

My ipod is cracked and it chipped away a little more last night and that's when my wifi stopped working. My wifi works on every other device in my house except for my ipod. Is there something wrong with my ipod?

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Try right next to the router
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- 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.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Could it be this?
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.

If you're trying use your hotspot and connected to wifi on your iphone, does the wifi stop working and start using your data instead of staying connected to the wifi?

Thanks for the quick response. What you have said makes sense but there is no rhyme or reason to he data used. I reset my cellular data counter to zero so both sent and received read zero. I was connected to wifi and let the phone to go into sleep mode. I waited about ten minutes and sent myself the same email four times, each with a 750 kb attachment. It was sent to my .me address so it was push mail on my phone. Sure enough I checked a minute later while bringing the phone out of sleep mode and checked the data. It showed just 10kb sent but 1mb received which just doesn't tally with the 4 x 750kb mails received. It just isn't making sense.
He knows what you asked and has already answered it!
I thought I had read where the iOS4 (or maybe just the iPhone 4) was supposed to be able to keep wifi connections alive while inactive. If the phone is sitting there on a charger with a wifi connection available, why use the 3G?

Hi Gunjan,
Thanks for visiting Apple Support Communities!
It sounds like you've already tried a few troubleshooting steps, but these links may offer some additional tips:
iOS: Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/ts1398
If you are using a public or commercial network that requires a login or subscription, see this article for more information.
Verify that you are selecting the correct network if you are in a location with multiple Wi-Fi networks.
Verify that the Wi-Fi network settings are correct. You can view and configure Wi-Fi settings using the following steps:
Tap Settings > Wi-Fi.
Locate the Wi-Fi network you are currently using and tap .
If you've verified that your settings are correct and the issue persists, try the following:
Tap "Forget this Network" to reset settings for this Wi-Fi network, including the password. Then try connecting to the network again.
Note: This can be useful if you identify a network issue and want to prevent the device from automatically using this network in the future.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings, including passwords, VPN, and APN settings.
Note: If the Wi-Fi network uses MAC address filtering, you will need to add the MAC address to the access list for the Wi-Fi router. The MAC address for your device is listed as the Wi-Fi address in Settings > General > About.
