Wifi switches off: temperature problem?

Hellom
my macbookpro 17" 2.5 GHz core 2 duo has the following wifi problem:
some 5 to 10 minutes after switching the machine on, WIFI switches off. WIFI icon in the top left still shows active but in wifi preferences it is of and cannot be switched on.
the bottom of my MBP also gets quite warm.
I don't know if that is related.
I recently switch from maverics to yosemty, but the problem with wifi stayed.
anyone can help?
thanks in advance.

Tecra R950-15E - Need WiFi switched off by deafult

Hi all,
I am new to the forum and would like to ask a question whose answer
I was unable to find both on the web and here in the forum (at least with my keywords; please direct me if missed it).
For some time I own a Tecra R950-15E running Win7 Pro 64bit and am quite satisfied with it.
The only thing that bothers me a bit is the WiFi mode.
I know that by pressing "FN+F8" I can switch the wireless modes (WiFi and 3G) on and off.
It seems that by default the wireless modes are switched on after starting the system.
I'd like to have it all switched off by deafult (mainly for saving battery) and only switching it on manually when I really need it.
By now I have to do it the other way round by switching it off manually after starting the system and I haven't found a setting to change it to my preference.
Does anyone have an idea to fix that?
Thanks

Unfortunately that did not help. I de-installed all wireless software and drivers and then rebooted. First the system installed drivers automatically from the net, then I installed/updated with the latest drivers and software from the Toshiba site. It is to no avail.
Interestingly, after "only" rebooting (immediate re-start) it memorizes the setting, but after switching it off for the night, the next morning the memory is gone and the WiFi is again switched on by default regardless of former settings. I also tried the administrative tool with WiFi switched off by default there, but that doesn't help either.
Thanks

6280 switching off radio problem

Hi all.
When using radio on my 6280 I disconnect hands-free (from the sales package) and receive message "Connect an enhancement". It’s ok.
But I receive the same message when I try to switch off the radio! So to switch it off I should connect hands-free and only then I will have possibility to switch the radio off. Looks like a bug.

Exactly the same! And it really looks strange..
For me it is not strange. I'm frequently using this feature when I have to turn off the radio quickly.
Imagine the situation when you are walking through the street, have the phone in a pocket and want to quickly turn off the radio for a minute or two. Sometimes I'm using this to answer phone without HF (ie. in a bus, where people look at me like they saw an alien when talking to myself (HF) ).
I just disconnect HF from phone. Then I reconnect it and radio works again.
If you left radio on and HF disconnected the radio will turn off automaticaly after 4-5 minutes. You can see a message "Radio off" or simillar.

WI FI switchs off automatically after 4.3 upgrade

Started facing these annoying problem after ios 4.3 upgrade.
Wifi switchs off when i leave my ipad without using it for like 20 min,
I used to keep ipad without using it like that for downloading apps at a time,but wifi will switch off.
Am really happy with 3.2.To be honest,These software upgrades are really degrading the device.
Any one facing same?Please give me any suggestions.?

Hi,
Tap Settings / General / Reset / Reset Network Settings.
Restart your iPad. Press and hold the Sleep/Wake button until the red slider appears. Slide your finger across the slider to turn off iPad. To turn iPad back on, press and hold the Sleep/Wake until the Apple logo appears.
See if that makes a difference.

I phone switched off, I phone switched off, I phone switched off suddenly

i-phone suddenly switched off and now can not switch on

Suddenly switch off / shutdown problem :
Because of hardware problems (panic.plist) my Iphone 4s replaced with new one. (if you have panic.plist in your logfile (diagnostic & usage), you should restore (using Itunes) your Iphone, if it is persist you have to replace with new one.
If you want to use Iphone Don't Buy Iphone 4s, you should buy Iphone 4(It is my second Iphone 4s, but I have still problem with battery - my first phone changed because of different hardware problems (suddenly swich off)) with 1 hour (soft condition) usage remaining battery is %90 (very poor.)

WiFi issue: Is it possible to change WiFi settings in a way that it does not switch off in the screen-lock mode?

I have iPhone 4 and 4s. WiFi is automatically switching off on both phones when they are inactive (screens are locked). It is connecting back after some seconds I unlocke the phone. But because I have no subscribtion for the Cellular data usage, I am being cuted from Internet all screen-locked period. All that time people are not able to reach me by email, skype, or other programs using Internet. It is quite uncomfortable, especially when waiting for something important! Is there a way to change this setting?

The iPhone does not shut down WiFi completely when asleep. It does use a power conservation mode. You should still receive notifications. There is no setting for this. It should work for you as it does for me if you don't have a network problem.
There are lots of problems reported with D-Link routers and they don't have a great reputation. If there is no help available from D-Link you may want to consider installing the DD-WRT firmware. It's available for the D-Link 615. See here for information: http://www.dd-wrt.com/site/index
By the way, you do have Notifications enabled for the Apps you are talking about right? See Settings -> Notifications and Mail, etc.

Hello I have upgraded my iPad again. It seems that something gets upset each time. This time my mailbox has become unstable. It does not receive or send mail. I know my wifi is fine because my laptop is fine. I have switched off the iPad again and again.

Not sure you got my earlier message so I am posing my question again.
Having upgraded my iPad to the more recent OSsomething, my mailbox no longer receives or sends emails.
My wifi is fine, checked with my laptop which works fine. I have switched off the iPad many times but the problem remains. Can anyone help?

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
That's not the same as turning it off or on.
Another things to try is to reset your settings. Use the Settings app for this.
Settings > General > Reset > Reset All Settings
You will not lose data but you will have to enter all passwords again.
If the problem persists after the reset check your email accounts on the iPad. You could delete them and add them back. This is also done in the Settings app.
Settings > Mail, Contacts, Calendar

HT2471 Wifi trouble- keeps switching off automatically.. Help

Hi
Currently using an imac late 2009 with updated OX lion 10.7.4- Having trouble with the wifi, it switches off automatically every 5 to 10 mins but doesn't prompt me for a password when I switch back on. Appreciate any help out there. thank you!

Hey G,
This is a common problem with wifi. The obvious answer is that your channel you have setup your WLAN on is experiencing noise from the surrounding devices (including other dodgy routers) and interferring with the signal.
Try changing your channel number on your router to another channel, usually automatically set to 11. I had no end of problems exactly like this but as soon as I changed channels, not a single drop even after three months.

When i wake up my iMac from sleep my wifi is disconnected. It also disconnects my iPad, my wives iPad, my iPhone & Sky On Demand which is connected via wifi. To reconnect all devices i have to switch off & then on again wifi on the iMac. Can anyone help?

Had the same issue and finally solved it. After the upgrade to Mavericks our 2 new Macbook Airs stopped connecting automatically to Wifi while the older machines the kids had still worked fine.
Bought a new airport extreme and problem solved. Our Airport Extreme was about 5 years old and was probably not compatible with the new OSX.
BTW this was after trying everything people suggested on this forum and a 4 hour marathon tech support call with Apple where we reinstalled the OSX.
***** to need to spend $200 but glad the problem got solved.
New extreme is also mega fast so its all good.

Does anyone know how to switch off the internal wifi test use a wifi dongle at a usb input?

HI
I am having problems connecting to wifi with a new Mac.
I have tried all kinds of things like shifting and monitoring my router's channel.
Short of using a power cube or crawling under the house and running a cable I have decided perhaps to use a Netgear wifi dongle.
I would like to switch off the internal wifi and allow the external device to connect.
With a new machine I really don't see why I have to do this.
Incidentally all my old devices have no problems with the wifi signal.
Cheers
Jack

Thanks for the suggestions.
Yes I have done all that was suggested on that site.
i have also been in contact with Apple Care.
I have also reset the router firmware.
I downloaded a piece of software called inSSIDer and checked out other wifi channels in the area. I moved my preferred channel to another ones that looked better however that is back on auto now and the router seems to be picking up channel 6 which is the best one and scores the most points.
I use a netgear wifi dongle on my 'smart' tv and was thinking of using that however I am beginning to thisk that 'powerline' products may be the answer.
The Mac is only two weeks old and I seem to be messing about with the wifi connection most of the time.
I actually cleaned the whole disk and reinstalled the operating system earlier this week.
Desperate or what!
Sometimes I think I should just return it but I like to solve problems and will keep going for a while before I lose patience.

Offline sync using Cellular when switched off and connected to Wifi

Problem with Spotify or Apple iPhone6?? I have the sync over cellular switched off in Spotify, but just synced whilst connected to wifi supposedly based on the WiFi icon showing but it used about 1gb of my cellular data. Latest iPhone6 update applied but might not be the reason. Anyone else experiencing this??? I have had to buy more data so I don't get charged.

I have had the exact same problem. With syncing 2 albums over 200Mb (of 500mb) of my cellular data gone!
Wifi was on (and working with websites etc.), mobile data for Spotify in iOS settings was enabled, syncing in Spotify via 2g/3g disabled and offline mode in Spotify was turned off.
This was on iPhone 5c with iOS 8.1, Spotify version 1.9.0.2744
Please help!

If you have followed the standard Apple troubleshooting processes (see user guide )
probably a trip to the local Apple Store Genius bar is called for before warranty runs out
Assuming the iPad has been released in your Country if not you may have to take it to a
neighbouring Country where it is available
This page will tell you ,via the drop down menu Countries that can support iPad
