WiFi disconnects sporadically, automatically reconnects when I unlock my iPhone 4

For the past week or so my Macbook has been dropping its wifi signal at home, even with full signal strength and no other devices showing connectivity problems. Trying to reconnect manually, it won't recognise my router, but strangely if I unlock my iPhone 4s, it will quickly re-establish the connection by itself... any ideas on why this would be?

10.9.2 upgrade and now wifi will not automatically reconnect after wake from sleep

I upgraded to 10.9.2 on my mid-2012 Macbook air and now when i wake the laptop from sleep the wifi will not automatically reconnect. I have to physically click on my network to re-join it.

Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
3. Reset the PRAM.
4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
7. Repair permissions on the startup volume.
8. Turn off Bluetooth and test.
9. Reset the System Management Controller.
10. Reinstall OS X.

How do i stop iPhoto from automatically opening when I connect my iPhone?

Hi, well as the title states:
How do i stop iPhoto from automatically opening when I connect my iPhone?
It's getting on my nerves...
Thanks.

This might also be helpful:
I wrote an AppleScript that asks me each time I connect the iPhone/camera/etc whether or not I want to open iPhoto. Usually I just hit return and it doesn't open, but once in a while I'll click Yes to open iPhoto and import videos from my phone. I just did it because it's nice to have a little reminder so I don't go for too too long without importing, but not have it slow things down each time I plug in.
Below is the script. Paste it into AppleScript Editor, then export it as an application. Then set Image Capture to open this app when you plug in your phone. Would love to hear if it's helpful for you or if you modify it to use other criteria to automatically import only at certain times or conditions.
Nathan
set question to display dialog "Open iPhoto to import photos?" buttons {"Yes", "No"} default button 2
set answer to button returned of question
if answer is equal to "Yes" then
tell application "iPhoto" to activate
end if

Is there a way to get my pantech uml290 to automatically reconnect when my windows 7 pc wakes up?

I have my windows 7 pro desktop set to go to sleep every hour (control panel, power options). When it wakes up, the pantech uml290 mifi device is invariably disconnected. I used to just restart the computer, but I found if I go into device manager (right-click my computer, properties, device manager) and click on network and click action, then scan for hardware changes it will reconnect it. But there should be a way to set the device so it reconnects automatically.

Update-PROBLEM FIXED by verizon support. I called my local verizon wireless store, who quickly got me tech support after running through a few things. I didn't know you could disable power management for just one device, but verizon tech support did! So you go into device manager, expand universal serial bus controllers, right click the first "root hub", click the power tab, and see if your device shows up. If it doesn't, continue this process through all the root hubs until it does.
When you find it, select it, and click the power management tab on the far right. Uncheck "allow the computer to turn off this device to save power". Restart the computer to save this setting. Then test it by putting the computer to sleep.
It did take about 30 seconds until the pantech uml 290 was connected, but it connected successfully three times in a row. I'm very happy with both the verizon store and verizon tech support. They were both very helpful and pleasant to talk t, and efficiently resolved the problem. I still think you pay too much for mobile broadband, and am a little put off that the problem existed in the first place, but I'm very happy to have this problem resolved.
One other piece of info. I got was that there is an upgrade, pantech 295 usb modem for only 30.00. So if I have any more problems I'll just try that. (It's still a wired, not wireless device, which I prefer.)

IPhone 5: Wifi does not automatically reconnect to my home wifi and kicks out randomly. (My wife's iPhone 5 too)

My wife and I just purchased the iPhone 5 and neither phone seems to want to connect or stay connected to our home wifi. It's not a terrible problem, but its kind of annoying to have to reconnect every time we pick up our phones.

"Ask to join networks" is off. I also tried turning off the phone and restarting it. My wife's iPhone 5 is doing the same thing. Could it have something to do with my router?

Why won't iTunes automatically open when I connect my iPhone 6

iTunes is set to open when I connect my phone but will not do so. I have to physically go to the program and open it each time I connect my phone. This also happens when I connect my iPad mini. This began when I upgraded to the iPhone 6. Before upgrading I did not have this problem.

Hey there Ray_J,
I understand that you want iTunes to be opening every time you connect your phone to your computer. You may wish to adjust this setting in your iTunes preferences to affect this behavior:
Prevent iPods, iPhones, and iPads from syncing automatically
Prevent devices from automatically syncing with this iTunes library when a device is connected. To sync a device, click the Sync button when the device is connected.
iTunes 12 for Mac: iTunes Devices preferences
https://support.apple.com/kb/PH19595
If this is unchecked, iTunes will open automatically when you connect an iOS device. Thanks for being a part of the Apple Support Communities!
Cheers,
Braden

WiFi disconnecting from iPhone 4S

For whatever reason, when my iPhone 4S is on stand by, the WiFi keeps on disconnecting. It only reconnects when I unlock the phone or go and manually connect to the WiFi network. I've never had this issue with any other iPhone that I have had and it is really annoying because I have to constantly check to make sure I am connected.
I've tried:
- turning my phone on/off multiple times
- resetting the Network Settings
- holding the lock button and home key simultaneously
Any advice how to fix the problem? If not, do you think Apple can help out?

Hello Sus G
Start your troubleshooting with forgetting the Wi-Fi network and then join again. If that does not resolve it, there are further troubleshooting steps that will take care of the issue.

At the iTunes menu bar, go to iTunes > Preferences.
Under the Devices tab, is "Disable automatic syncing for iPhones and iPods" selected?

HT201328 when I unlock iphone 4 what happens to my passcode?

When I unlock my iphone 4 and restored to factory setting, it does not accept my passcode. Does anybody know about default passcode?

There is no default passcode, the passcode would be whatever you had it set to.

When I use my IPhone 4S to view the Shaw Go Movie Central App when I am at home I only use WiFi which is automatic, I start watching a show and sometimes I will get a message like "you can not use your cellular for video playback" or something close to that. Then I received an email from Telus saying I had used my 3G instead of Wi-Fi using 75% of my data. How can this happen when I'm on Wi-Fi at home? If it switched to 3G for some reason I should have been disconnected and not just transferred to 3G network using up my data. What is the fix for this??

It doesn't have to be that complicated, Verizon iPhones come unlocked, just tell VZ you're going on Holiday/Traveling and suspend the service, no need to pay for service if you're not going to be using it. Pick up local SIM cards in the countries of your choosing, pop them in, re-activate iMessage and you're set!
I recommend getting a SIM card from the Three network in England, they have great EU roaming rates and free like-home roaming in Italy.
Set your phone's region to match the country you're in, it'll save from some headaches when calling local/international numbers.
To answer your questions,
1. If you choose not to have a local SIM card, it is good to keep your phone in Airplane mode to save battery.
2. Make sure the two iPhones have different names to reduce sync/restore issues.
3. If husband has an iPhone also, you can chat with iMessage/Facetime, just give him heads up about the new number you'll have. Otherwise, use Whatsapp if he's got an Android. You can activate Whatsapp with your American number or the international number if you choose to get a SIM in Europe.
Also, Get the MagicJack app and/or Google Hangouts, both of those apps provide you with free calling to the USA and Canada using any internet connection. Google Voice is another good way to SMS across the seas.
Let me know if you need any more tips for iPhoning across the pond.
