IMac won't automatically connect to Wi-Fi.

iMac won't automatically connect to Wi-Fi. I can connect manually using "Network Diagnostics". After I select my router the connection is made. How can I make it automatic again? I only have a medium/low expertise. Software is Mac OS X v10.7.5.
The problem all started when I let Nintendo do a computer share in order to connect to a Wii U. The tech was into so many things I couldn't keep track of them. I have tried everything I know to fix it but to no avail. I even let Nintendo try twice to correct this...no luck.

Hello, how do you fetit to connect?

My iMac won't automatically connect to wifi after waking from sleep mode

After dowloading the newest software update and performing a firmware update for my Airport router, my Imac won't connect to Wifi automatically after waking from sleep mode

Please re-download and install the 10.7.3 update. You can locate it at 10.7.3 (Client Combo). Follow the on-screen instructions. Then test it out, if you still have the same problem please restart, when you hear the startup tone hold down the Option Key and then choose the Recovery Partition. Then open Disk Utilities and Repair Disk Permissions 2x. Then exit DU, restart normally and re-test.

I updated my 4s to IOS 8 and now it won't automatically connect with my Ford SYNC. I have to turn the phone off and then on again for it to connect.
Why is this? My husband's 4s is still on IOS7 and it still connects automatically.

I do not know if this will help.
For a limited time Apple will allow you to downgrade to 7.1.2. Hurry do not wait.

I can't make my iphone 4 forget the hpsetup network which keeps showing up at work. My phone won't automatically connect to my company's wireless network.

I can't make my iphone 4 forget the hpsetup network which keeps showing up at work. My phone won't automatically connect to my company's wireless network. I have to reselect it everytime I come to work.

Settings/General/Reset - Reset network settings will "forget" all WiFi networks so you can select them again.
If the problem with your company network is not solved by doing this, are there multiple sites that have the same network name for the company network? Or is it the default network name for the router type (e.g., DLINK, LINKSYS, etc)? If so, this is what is causing the problem and there is no solution other than convincing IT that it is a bad idea to have duplicate network names.

My iMac won't stay connected to the internet, even though all other computers in my house stay connected

My iMac won't stay connected to the internet, even though all other computers in my house stay connected, and its connection is set up the same way my fiance's macbook is (his macbook is about three years older than my iMac). Every time my computer goes into sleep mode and I come back (even if it's mere seconds after giving the black screen) I have no internet connection. I discovered a workaround for it some time ago, but now that is working less and less, and now my computer randomly disconnects WHILE I'm actively using the internet. Just a few minutes ago, the connection refused to come back until I restarted my computer, even though once again all other computers in the house were connected. The workaround I discovered before and which doesn't work as reliably now, is to click opne Airport at the top right of the screen, click "Open Network Preferences," then click "Assist me," then click "Diagnostics," and wait for everything to turn green again, signalling a connection.

Let's check the quality of your connection since signal strength alone does not insure a good connection. The "bars" that you see at the top of the iMac screen are there pretty much for show.
Hold down the option key on the iMac while you click on the Apple icon at the upper left corner of your screen and select System Profiler
Look down the list of items at the left of the window until you find the setting for Network, then click on AirPort.
In the window to the right, look for any listings of your wireless network name. You may possibly see two listings for the wireless network name.
We need for you to list the information that you see for Signal / Noise. These will be negative numbers. Post back with your findings and we will continue.
In the meantime, please move any cordless phones that you have or any other electronic devices that are near the iMac as far away as possible from the iMac.
If the iMac is located in a corner or an enclosed area, give it as much room as possible since the wireless antenna is on the back of the iMac and it needs to be able to "see" the room.
Anything that you can do to minimize the number of obstructions like walls or furniture etc between the iMac and the wireless router will help the cause as well.

Imac won't stay connected to wireless network

I recently moved and now my imac won't stay connected to my wireless network. Every other device connects just fine, so it's not the service, or the location, because devices are all in the same room.
Every time my computer goes to sleep it seems to completely forget how to connect to the internet. There is only one Network (mine) listed in preferred networks. The computer will connect only if I go to System Preferences and run through the Network Diagnostics to tell it exactly what to connect to. Each time it says my connection and internet are fine, which I know.
Please someone tell me how to get it to remember my network so I can stop going through the Diagnostics every time I want to use my internet.

Though all of these steps may or may not be needed, I'm including them all.

My Photosmart C410 won't automatically connect to the Network

My Photosmart C410 won't automatically connect to the Network, I have to put in my password for the router every time I turn on the printer from the printer keyboard. Is there anyway that the printer will automatically connect to my network?

Tell me about your network - router brand/model, encryption type (WEP, WPA, etc) and ISP type (DSL, Cable, etc).
When you turn off your printer, are you totally removing power from it (like shutting off a power strip)?

IMac no longer automatically connects to Airport

Hi all.
Used to be (up to a week ago +/-) that as soon as I turned the iMac ON, it would automatically connect to the Airport (WIFI mode).
It no longer does that and if I want to connect to my network via Wifi, I have to open System Preferences/Network and manually enter the network's name and password. The iMac then connects (and stays connected) without problems.
The iPods and the iPad keep connecting automatically to the network without problems.
The Airport Extreme router firmware's was updated today to 7.6, but that had no impact on this problem.
In the past week or so, the power has been (abruptly) cut on the line that powers the router. Could this have had an impact???
Thanks for any ideas.

Try the following...
1. Delete Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Delete the network(s) you regularly use from the list
2. Delete AirPort Keychain Entries
- Launch the "Keychain Access" application located in Applications/Utilties.
- Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
- Restart, or log out then back in.
3. Add Preferred Network(s)
- System Preferences > Network > AirPort > Configure
- In the "By default, join:" pull-down menu, select "Preferred networks"
- Add the preferred network(s) using the "+" button.
- Restart or log out then back in.

Won't automatically connect to Airport network after 10.4.8 update

After updating my Mac Mini CoreDuo from 10.4.7 to 10.4.8, it will no longer automatically connect to our Airport Express based Wi-Fi network. Even though the Network settings in System Preferences have not changed, and they do list it as the preferred network, it still will not automatically connect after log in.
Does anyone have this issue, and know of a solution?
(aside from the workaround of manually connecting after log in, and after waking the computer from sleep).
Background: My setup is to join preferred networks by default, the network name continues to be the one listed, the network still continues to show up in the Airport network list in the upper right corner of the screen. In essence, the Mac sees it is there but just won't connect to it. We have two other Macs in the household, both are PowerPC based, and both were updated to 10.4.8, and they have no issues. They continue to automatically connect to the Wi-Fi network we have. This seems to be with our Intel Mac only.
Mac Mini CoreDuo Mac OS X (10.4.7) Mac OS X 10.4.8

This all happens most likely due to a corrupted key chain (entry).
For instance, if you choose to keep your local Airport password stored in your personal key chain it needs to be accessible by the private Apple Airport Framework used by the network preferences. If this by any means, is not possible - the automatic login into you Airport WiFi network cannot take place.
All you have to do to get this fixed is:
1) Launch your Keychain Access Application located at: /Applications/Utilities
2) Open the Keychain First Aid (under the Main Menu: Keychain Access)
3) Set the Radio Button to Repair and enter your Keychain Password (most likely your personal password)
4) Start.....
Now after your personal keychain (name=username) is repaired it might be listed double in your Keychain List Window (it depends how you've setup the keychain). If so, NEVER DELETE ONE OF THIS ENTRIES because that's obviously a cosmetic bug in the Keychain Access Application but not harmful. Just look in your local Preferences Folder, locate the file "com.apple.keychainaccess.plist" and thrash it. Re-launch the Keychain Access Application and there is only one again.
Restart your Mac and........
After all I think anything should be back up to how it supposed to be. :-))

Iphone 4s bluetooth won't automatically connect to my car

my iPhone 4s would always sync to my car until recently. Now I have to reboot my phone each time to get it to sync. I have reset the networks; deleted it out of my car and re-synced it; and I have clicked forget this device from my phone, But still won't automatically sync.

You can turn on BT tethering but it disables Wifi so if I have to do that step every time I get in my car, I just as well manually connect on BT every time.

Hello Juanita289
Check out the article below to troubleshoot issues with connecting to WI-Fi. You may want to reset the Network Settings by going to Settings > General > Reset > Reset Network Settings. It will not delete remove any personal data besides and known Wi-Fi networks that you have joined in the past.

My imac won't stay connected to a server. How do i fix this?

The only way i can join a server is if i restart my computer. After leaving the computer unattended for a while, the server wont connect. when i try to reconnect through Finder>Go>Connect to server, it doesnt open...
I also tried to go to my system preferences>accounts>{ admin }>Login Options>Network Account Server>Join.... the error message comes up that says "unable to add server, could not resolve the address"-- even when im connected to the server.
My question is this: how do i stay connected to the server or configure my computer to automatically connect to the server when i start up or not disconnect?

Try:
