Macbook pro with maverick 10.9.2 loses internet connection after waking from sleep

I am on a MAC Pro desktop and I am having the same issues. I go to system preferences and just click the network icon. Then I close mail and when it opens it now sees the network. This is getting very annnoying.

MBA loses internet connection after waking from sleep

I have a new Macbook Air running Mavericks and new 802.11ac Airport Extreme router.
My problem is that the MBA drops the internet connection after waking from sleep. I tried the solution offered by the OP, but it didn't work.
In my case, here's what I have to do to get a connection again. I open the Network preference pane, and then choose "Assist me..." and then "Diagnostics". Invariably it will show a green light beside Wi-Fi, Wi-Fi Settings and Network Settings. I have 5 bars showing in the WiFi menu bar icon. But ISP, Internet and Server will be yellow.
When I go through the steps prompted by the wizard, the ISP/Internet/Server lights turn green on the third screen where I select the wireless network I want to join.
It seems as if it's connecting to the WiFi network when it wakes from sleep, but losing the internet connection?
Note: I have a new iMac as well running Mavericks and don't have this problem with it.

My MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode

Hello, everyone. Since I updated to Yosemite, my MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode.
Does anyone know how to fix that?
Thanks in advance,
Arthur.

Hi, arthurpacifico.
Thank you for visiting Apple Support Communities.
Here are a couple troubleshooting steps that I would recommend trying to see if it corrects this issue.
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
Reset your computer’s PRAM
http://support.apple.com/kb/HT1379
If the issue persists, try the troubleshooting steps I have attached below.
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.Restart your computer.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

IMac loses WiFi connection after waking from sleep on OSX 10.8.2

Bought a new mid-2011 21.5 inch IMac this week. It is not re-establishing WiFi connection after waking from sleep. Was happening on OSX 10.7 that it came with, so updated to 10.8.2 and same problem exists.
I am running a mid 2012 MacBook Pro with Retina Display alongside, on OSX 10.8.2 and no problems at all. Cannot work out what is causing the IMac to fail and neither can Apple!
Could it be the Netgear Wireless Router 3 years old? Full signal strength!

13"w/ext display loses WiFi connection after waking from sleep

I have my 13" macbook pro (mid-2009) connected to an external monitor. When the system goes to sleep and wakes up, the wifi is disconnected and an error window pops up saying something to the effect of another computer is using the IP address assigned to my computer.
If I reset the modem it usually works, otherwise I must wait about 15 minutes for system to connect again.
It does not happen if there is no monitor connected to the notebook.
Is there something I can do to stop this from happening?

I have a strong suspicion that I am getting wifi interference from my neighbors. Several new wifi signals have appeared in the last month coinciding with new neighbors moving in and some old ones getting wifi. Upstairs, I can pull up 6 or 7 networks, some broadcasting on the same channel. Downstairs, where my MacPro resides, I do not see those networks. My problem seems to manifest itself on my MacBook Pro when I move upstairs and can pick up the extra networks.
When I power cycled my router this morning, I noticed it changed channels from 11 to 6, indicating that the Auto setting is determining a better channel. Also, this problem seems worse after 5 pm. So, I'm chalking this one up to neighbor interference. If my iPhones could use the 5 GHz band, I'd use that exclusively... or maybe it's time for a simultaneous dual band router.
I wish I had a dollar for every time I've advised a customer that interference was the cause of his wireless connectivity issue.

Lose broadband connection after waking from sleep

I use Power Mac G5 OSX10.3.9 to connect to the internet, via Sky Broadband (in the UK) and Netgear DG834GT modem with ethernet cable (not wireless). I can connect with no problem and everything is fine, as long as I keep my G5 on or shut it down completely and turn it back on again later. However, if I put it to sleep for more than half an hour, then, when I wake it up, I lose broadband connection. The connection is still alive for a few seconds after I wake up, and other computers connected to the same modem can connect AS LONG AS THE G5 IS STILL ASLEEP. But it appears that the act of G5 trying to connect back to the internet kills the connection. Rebooting G5 doesn't help. The only thing I can do to reconnect once I lose it is to reboot the modem (by turning it off and turning it back on).
I cannot determine whether this is a problem with the modem or with the G5. Any idea? Thanks.

I quite serendipitously discovered what was causing the problem and how to stop it, although it's not a solution per se. I am explaining what I discovered in detail below in the hope that it might help future users who might encounter the same problem.
When you log on to http://192.168.0.1, you are connected to the Netgear DG834GT router itself (after typing in the username and password). On the "router status" page, there is a button called "show statistics." If you click on this, you open a window with a running display of statistics on the phone line, like upstream and downstream noise margins and line attenuation. The line is scanned every 10 seconds to give updated information in real time.
I always had this page open on my desktop, because I was having problems with line noise and wanted to know the current status of the line and its noise margin at all times. When the noise margin was low, my connection speed was incredibly slow.
I discovered that it was the "show statistics" page open that cause the loss of connection when I wake up the computer. If I don't have the "show statistics" page open, I don't lose the connection when I put G5 to sleep and then wake it up.
I tried it with different browsers and discovered that Safari and Netscape do not have the same problem. I do not lose connection even if I have the "show statistics" page open in Safari or Netscape. It only happens with Firefox (which I usually use) and Mozilla. If I have the "show statistics" page open either in Firefox or Mozilla, then I ALWAYS lose the internet connection when I wake up the computer.
This is not a true solution in the sense that I don't know why this happens or how not to lose connection when the "show statistics" page is open. But at least now I know not to have the window open.

Power Mac G4 loses internet connection after going to sleep

Run down of computer: I have a Power Mac G4 tower, PANTHER OSX. I have wireless internet through our cable company—I use a wireless router. When I am connected to the internet, and browsing the web or something, if I let the computer go to sleep, it loses connection. I have to go back up to the little signal icon and reconnect to my wireless network.
I suspected it might be a setting through the router, but when my computer was comletely unplugged, and absent from the apartment, the other computer (G5 imac–TIGER) which was having the same problem, suddenly was staying connected even after going to sleep. When my computer came back home and was hooked back up, suddenly the other computer had the same problem again. So, I concluded that my G4 tower was the culprit, and perhaps not the router. We share a wirless network, so it's not surprising that this is the case.
I know there must be a setting somewhere in preferences or something that is telling the computer to disconnect from network when computer sleeps. I have looked everywhere, and can not figure it out.
It's really annoying to have to reconnect each time I use my computer. And just to reiterate, I get internet through a cable modem using my airport card, so please answer the question with this in mind as settings are totally different from dial-up. I do not use PPP.
Anyone experience this problem? Or know how to help?

Tried that too! Notta.
This one's really a pickle! Even the Mac specialist at my office was baffled! He suggested shortening the name of my computer...(Jamie Cendroski's computer)...I didn't really understand how this had anything to do with it...but he's supposed to be the expert. He also suggested trashing my keychains and making new ones. I messed around with them, but I don't know enough about this stuff to be bold enough to trash them yet. I'll do a little more research before I do so. I think he might be onto something with the keychains though..?

I am trying to find an app or software to burn iMovie 11 slideshow to a dvd. I have a MacBook Pro with Mavericks. There are a lot of DVD Creator apps at the App store. Looking for a recommendation of what to use and tips. Thank you.

I've been using "Burn" for years and it has been the only DVD burning software I have ever used for the mac. I have never needed to look at other apps. Unless you want something that has more bells and whistles such as Roxio's "Toast" : http://www.roxio.com/enu/products/toast/pro/overview.html
There are thousands of quality free apps out there for the mac that are not part of the App Store. All you have to do is read reviews online, do a little search, the Apple forums are full of recommendations from experienced users that have been here for years...

I have a cd rom for my italian class, which I cannot open on my macbook pro with mavericks installed, someone said I need Rosetta! Help please

I have a cd rom for my italian class, but am unable to load it on my macbook pro with Mavericks installed.
Someone has said i need Rosetta, but understand that Apple stopped installing this!1
Can anyone suggest anything to help me??

Many educational CDs have not been upgraded due to lack of funds in the educational market to pay for the such updates.
This situation is due primarily to the fact that one of the major political parties in this country favors tax cuts to the rich while cutting federal educational support funding (or eliminating the federal Department of Education altogether).
However, you can restore Rosetta and run your educational CD if you install Snow Leopard Server ($20) into Parallels (up to $79) for use in Lion/Mt. Lion/Mavericks:

Everything on my Macbook Pro with Mavericks runs very slowly

I have a 13" macbook pro with Mavericks operating system, and it is only a little over a year old. In the last 2 or 3 months everything on the computer has been running incredibly slowly.
I first noticed it when streaming online videos, the audio would be several seconds ahead of the video, but the lagging has started everywhere else too. When I type the text appears several seconds after it has been typed, it takes much longer than it should to scroll down webpages and the cursor often freezes, I have even noticed a very long lag switching between webpages or applications.
I have very few things saved on this computer, just some Word documents and pictures. I did have Sims 3 installed but I uninstalled it thinking it may be the problem.
I have also noticed a very audible metallic plinking noise that could be unrelated. It started ] maybe 2 months before the lagging did and sounds like it's coming from the bottom right hand corner of the computer. I'm considering resetting my computer to factory settings because I haven't been able to find anything to fix this issue.

The hard drive is located in the bottom right of your model and I experienced a very similar issue twice in less than a year of purchase. I suggest you back all your data up as soon as possible as it may be the signs of a hard drive beginning to fail. My symptoms were it would take longer to start up and I would get the spinning ball when I secondary clicked. Before it would fail, I would try and repair errors found in disk utility and it would say it could not be repaired, back up as much data as you can. By that point, it was too late to back anything up. From there, I would get a loading bar on startup and once it loaded, it would shut down. But it could be a less serious issue as well. It could also be the SMC, PRAM, or errors in your hard drive's coding. But before you follow these steps, back all your stuff up that you want or need in case it is your hard drive. Boot the machine into recovery mode by holding in command and r as soon as you turn it on. After it loads, you should get a box to pick your language. Select your language and select disk utility. In there, click Macintosh HD and verify the disk. If anything appears in red text, there are errors that need to be fixed. All you have to do is click repair. If it says they can't be repaired and to back up your data, your hard drive may have failed. To reset the SMC, plug in the mac and shut it down. On the left side, located the control, option, and shift keys. Hold those down along with the power button. Hold it for a few seconds and let them go. It's normal the machine won't turn on and the light on the charger will change state. Next, reset the PRAM. Shut down the Mac and located command, option, P, and R on your keyboard. You're going to turn on the Mac and as soon as you do so, hold those four keys down. It's going to shut down immediately but keep holding them in. It will turn on and make the "bong" noise like it normally does. Let it cycle about two or three times and let the keys go and wait for it to start up.
I hope this helps and good luck!
