Dropped Internet Connection on Mac Mini

I have a new Mac Mini and it's connects to the internet via Wifi with no issues and the internet works fine. After it's been connected for awhile I'll pull up Safari and it won't load a page but shows that it's connected. If I disable the Wifi and re enable it, it'll pull up the webpage with no problem. All other devices connect and hold the connection but the Mini including Win 7 systems and Android devices. Any Ideas? Thanks.

You're doing quite well for new to Macs!
Apple really doesn't seem to have this Airport/Wifi thing as well in hand as I think they should.
Tough to tell, especially in higher OSX versions as everything is far more removed & more steps, but se if you can adapt these older steps, they're basically the same, but with little aggravating additional steps...
The Interface that connects to the Internet, needs to be drug to the top of System Preferences>Network>Show:>Network Port Configurations and checked ON.
10.5.x/10.6.x/10.7.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
Safe Boot, (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, reboot once more.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.
Open Keychain Access in Utilities, use Keychain First Aid under the Keychain Menu item, then either check the Password under that item, change it, or delete it and start over.

Syncing to a new computer should give you the opportunity to replace the exisiting contents with the new.

AEBS Dropping Internet Connection q 45 minutes

I have the new airport extreme base station. I bought it January and it has worked flawlessly for the past 6 months. recently, in the past week or so, I began getting a dropped internet connection happening every 45 minutes or so.
About my set up:
Cable modem supplying connection to AEBS via ethernet. VOIP box connected to AEBS via ethernet getting internet connection from AEBS. Playstation 3 connected via ethernet to AEBS. Airport Express base station linked to airport extreme base station wirelessly (of course) to share printer connection via USB. iBook G4 1.2ghz running Mac OSX 10.4.9
Trouble Shooting.
Originally I would unplug the cable modem for 30 seconds and plug it back in. This would reset the connection and i would have service again for 45 minutes. I decided to test whether or not it was the router or modem that was kicking me so I unplugged the ethernet cable coming from the modem to the AEBS and plugged it directly into my computer and turned off my airport connection, essentially hardwiring the ibook directly to the modem. I got kicked off again. At this point i drew the conclusion that it was the modem and contacted my cable company. After a bunch phone conversations that essentially accomplished nothing, they sent a tech out to my house. He replaced my old (3 years) cable with a brand new one to test out. I left my computer wired directly via ethernet to the new modem and this time DID NOT receive any drops in connection over a period of 4 hours. I reconnected the ethernet cable from the modem to the AEBS and reset my connection and decided to test out wireless. It dropped me again in 45 minutes. I left the cable modem connected to the AEBS via ethernet and unplugged the ethernet cable coming out of the AEBS that gos to my VOIP box and plugged my computer into the AEBS via ethernet and disconnected from airport on my computer. I was again dropped in 45 minutes. I reset my modem and unplugged the ethernet cable coming out of AEBS that gos to my Playstation 3. Again I was dropped within 45 minutes. After that, I reconnected both the PS3 and VOIP box ethernet cables and unplugged my computers ethernet cable from the AEBS and have just been using the wireless connection and resetting the modem every 45 minutes when it drops. Oh yeah and I forgot to mention that I plugged the Playstation 3 directly into the cable modem via ethernet and played online for 4 hours without interruption/disconnect. Anyways, I am back to square one. I believe based on the evidence above that the problem lies within the Airport Extreme base station router some how, but I have no idea what the problem is.
What happens when my connection is dropped:
I can be doing anything from using an instant messaging service to trying to load a web page using firefox or safari. Basically the page fails to load, i get a message saying it can't find the server. Usually at this point I will open up network utility and try to ping yahoo.com. It doesn't ping and says it can't find the server. I go to the modem and unplug the power for 30 seconds and replug it back in. As soon as everything back up I have my connection back.
What the cable company did:
They looked at their connections, including the fiber optic node for the area. They did not find any outages or problems within their system. They plugged my coxial cable into a modem/tester box (not sure exactly what it was) to evaluate signal received via coxial cable which they said was working properly. they checked my cable connection from house to street and didn't find any compromises in the wire/cable.
I have downloaded and installed the latest firmware for my AEBS. I am out of ideas. Can anyone help?

ibook G4 Mac OS X (10.4.3)

I had the same problem earlier this year with my cable carrier. At first I thought it was the modem so I replaced the Dlink with an Apple Extreme and it still kept happening. After some research on MacInTouch I found that using an earlier version of the base station software made the problem go away. So I never updated and all was well with the world. Till last week and now like you I am dropping connections every hour or so no matter what application I am running or what site I am on the internet.
A friendly tech admitted to me that there was a problem with the way the modem communicates with the provider and that they were aware of the problem but that there was nothing he could do to help me.
That is when I cured the problem temporarily by using the base station software from 2004. If I find an answer to the return of the problem I will post it. Please let me know if you find a solution.

Help - getting internet on a Mac mini (sans Airport) through Express

Hi, let me give you a little background. I am trying to connect a mac mini that as the title says has no airport. I have used an airport to configure it (through an ethernet cable) to join an existing network. Now, once set up I can hook my powerbook and express together and connect to the internet (all of this is with the PB's airport turned off mind you). That leads me to believe that everything is going well, so I take the cable out of my PB and connect the Mini. At this point nothing happens, no internet connection is formed. I try to access the settings for the Express through the Airport Admin utility, yet cannot find it unless I have just factory reset it. I also tried downloading the latest AirPortUpdate from the Apple site.
So there you have it, anyone know how to get the darn Mini on the network through the express?

Use "Applications > Utilities > Airport Admin Utility" to configure the Express base.
If that's done correctly, the Mini should detect the internet connection automatically after a few seconds after pluging the Ethernet cable in.
If not, check "System preferences > Network" and select "Automatic" as "Location".
Post back if you succeeded or not.

Problem with Dropped Internet Connections on AE/Macbook

I have a dual band Airport Extreme connected to Comcast Cable. I use a first generation Macbook to access the airport. The problem is that I keep on getting dropped Internet connections. The signal strength is shown at the top rhs of the screen as being full strength (4 bars).
If I swap out the router for a Linksys WRT54G, running DD-WRT, the combination works perfectly without any dropped Internet connections. Also, If I connect the Linksys to the AE with the Linksys acting as a wireless client repeating the signal, then I can connect the Macbook to the Linksys again without any dropped internet connections.
There is something about the Macbook connecting directly to the AE. It happens intemittantly but probably multiple times a day and is very inconvenient. The only way to get it back is to reboot the router or stop/start the aiport on the Macbook.
I have tried just about every possible setup on the AE including splitting the 2.4 and 5Ghz radios into two separate ssid's and changing the channels. I am using the latest AE firmware. I have also taken the AE back to the Apple store and they have swapped it for a new one.
I dont get the same issues with my windows clients or my ipad (although i have experienced issues while steaming video - but I think that may be a different issue).
Any suggestions/advice would be greatly appreciated.

Use the advice in this thread to investigate the signal and noise levels that the Mac sees:
http://discussions.apple.com/thread.jspa?threadID=2347845&start=1
What you may see if an increase in noise when the connection drops.
If that doesn't show anything useful, it might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease". Note that the fix this step implements may be temporary.
6) In the folder /Library/Preferences ( _not_ <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

I want to Connect my Mac Mini as a Slave to a Mac pro Server while at the same time using the Mac mini's thunderbolt ports peripherals ( ie monitor, Sound Card, Hard drives) Creating a poor man's new mac Pro. Can this be Done?

I want to Connect my Mac Mini as a Slave to a Mac pro Server while at the same time using the Mac mini's thunderbolt ports peripherals ( ie monitor, Sound Card, Hard drives) Creating a poor man's new mac Pro. Can this be Done?

Well, I really would love the new unreleased mac pro however , I'm not sure of the expected cost , Everyone speculates from $3,000 to $8,000, in which I may have to wait a while to purchase.
To the point .... I want fully functional thunderbolt ports to be on the current mac pro's .... wonder if anyone had workarounds yet?... or could I chain the the current mac pro to a mac mini to make that happen?

What do I need to connect my Mac Mini to a TV using the S-video jack?

Radio Shack didn't have anything in the store and suggested
that what I needed (something with an S-video connector
at the adapter end and a co-ax/F-connector at the TV end)
would cost $100.
What should I be looking for? I'd like the option to connect
my Mac Mini to a TV (with enough resolution to read text,
which isn't the case with a video-RCA cable), especially in
a hotel room (using the Mac Mini as a laptop!).

The DVI to video adapter
<http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/6454000/wo/jP1F dznaaoNs2dPRALa1K0FqrB2/3.0.21.1.0.8.25.7.11.2.3>
will give best results using the S-Video. Next best is composite video. If your TV set does not have either of these, you will need a RF modulator to connect to the TV antenna connector. For best results get a modulator that takes S-video. It should cost a lot less than $100.00 Radio Shack has one for $25
<http://www.radioshack.com/product/index.jsp?productId=2103095&cp=&origkw=rfmodulator&kw=rfmodulator&parentPage=search>
No matter what connection you use, a standard TV will not give you better than 640 x 480 resolution, so it will always be hard to read small text.

How do i connect my mac mini to a kvm switch using the hdmi to dvi adapter?

I want to connect my Mac Mini using the HDMI to DVI adapter to a KVM switch cable. I have an Iogear KVM switch. The cable from the KVM switch has a male VGA end connection. I have been trying to determine the right adapter to connect the female DVI connection to the male VGA connector. I will be using the Mac mini and a PC running through the KVM switch. This is doable as the iogear switch is compatible with both a PC and a Mac. Any ideas out there? Thank you.

You would need to get HDMI or DVI to VGA CONVERTER, not a simple adopter. The converter requires USP connection for power. HDMI is only digital while VGA is analogue.

If your MIni has a mini displayport or Thunderbolt port yu can get a les expensive mini displayport to VGA afopter.

When I connect my Mac Mini 2011 with Lion to a TV via HDMI and an earphone cable is plugged in, it´s not possible to choose sound out via hdmi, as opposed to connection via minidisplay port. Anybody knows how to fix this?

Was just on the phone with Apple about this.
The solution was as follows for me anyway...
Go to your Finder
Choose the Go Menu
Choose Computer
Choose your Macintosh Hard Drive
Choose your "Library" Folder
Choose the "Preferences" Folder
There should be a folder called "Audio"
Move that whole folder to the trash
Empty the Trash
Restart from the Apple Menu
When you are back up and running;
     Choose System Preferences from the Apple Menu
     Choose Sound
      In the output tab you should now be able to make the HDMI "Sticky"
      Enjoy your sound over HDMI and no more dirty knees or broken backs unplugging the desktop speakers!

Connecting my Mac Mini DVI video output to Dell W3706MC LCD TV VGA Input

I tried connecting my mac mini to the Dell W3706MC LCD TV VGA input but it wanted me to change the resolution of the mac to 1360 x 768 at 60 Hz. I did that but it still would not display the video. I tried my PC laptop and that worked fine with different resolutions. So I know that there is nothing wrong with the TV. Did anyone experience this same problem?
Any help would be great.
Thanks,
Karl

I'm confused about your comment "it wanted me to change the resolution of the mac to 1360 x 768 at 60 Hz." I presume the way this was communicated was through a dialog box, correct? But if you could see a dialog box, that means you had a working screen at one point, correct? Why don't you just run at that resolution?

I have Snow Leopard 10.6.8 on my MacBook. Constantly dropping internet connection or message "error connecting to the network" comes up. No wireless connectivity issues with windows 7 laptop or iphone.

I have a MacBook with Snow Leopard 10.6.8. The last few weeks it has been constantly dropping internet connection, and one of these messages appear on the page: "Safari cannot open this page because the server where this page is located isn't responding" or "Safari cannot open this page because you are not connected to the internet" comes up. I will check Wifi and I am connected. No wifi connectivity issues with iphone or windows 7 laptop, this doesn't happen with either of those devices. I have unplugged and reset router, cleared cache, still happening. Any ideas? Thanks in advance.

Extreme Base Station suddenly dropping internet connection

I have an Extreme Base Station (802.11n Fast Ethernet) which has been providing wireless internet and printing to two imacs pretty flawlessly for several years. It seems to be a fairly simple network. DSL modem (to WAN port) and USB printer cable plugged into back of Base Station.
Several days ago, the Base Station began dropping connection to the internet every few minutes. If I connect the modem directly into the computer, I have no problems with losing connection. So, I began looking for solutions online and have been trying everything I could find to do. I've scoured the forums here, and everywhere and read a bazillion posts.
I've done a hard reset of the Base Station, I've tried different channels, I've unplugged, waited ten minutes, and replugged in a myriad of sequences, including unplugging both the modem (Zhone/Paradyne 6381-A3) and Base Station overnight. The only thing I haven't done is roll back the firmware (currently 7.4.2 I believe). I'm still experiencing the same problems and am at my wits end. I've spent hours now trying to fix it and need to do other things like shop for groceries and vacuum! So, I'm posting, in hopes someone might be able to point me in a more productive direction.
Is it possible the Base Station hardware is failing? What are the signs and symptoms? I hate to spend another $179 and still have the same problems.
Thank you.
Most kindly,
---Susan

Dear Bluenova - ( +or other interested readers+ )
I know that this reply is two months since this topic was initially posted.
This is a longstanding Airport Extreme ( AEBS ) problem that's been noted since 2006-2007.
It has been an ongoing issue for me -AND- I continue to experience it even after recently upgrading my AEBS.
I finally called AppleCare in mid-Sept. and opened a formal problem case report.
As of today (Oct 15, 2010) I still have an open & unresolved case with AppleCare.
The problem has been escalated twice -and- is now referred to Engineering Dept for research & resolution.
I was curious what steps or actions you have taken -and/or- if you still experience the problem.
_Readers Please Note_
Many users have posted messages regarding problems with Airport Extreme *+DROPPING CONNECTIONS+* .
However, with careful reading, it becomes obvious that many forum posters are not sufficiently clear
-and- often confuse or do NOT make the distinction between ..... DIFFERENT TYPES OF CONNECTION PROBLEMS.

If you suspect that you are having the *dropped internet connection* type problem,
YOU CAN CHECK & WATCH IT HAPPENING IN THIS MANNER
Set Airport in Menubar to *"SHOW TIME CONNECTED"*
. *- +and also+ -*
Open Airport Utility --> AIRPORT --> SUMMARY window

Now, once the internet connection drops or is lost ...

If you have a new or ongoing problem that relates specifically to ....
.... Airport Extreme – dropping or losing *Internet Connections* ... ( +not wifi connection type probs+ )
.... please let me know.
I would like to be able to correspond directly with others via email to share info
(such as what modems, ISP's, time of day or conditions with which this problem has been found to occur)
I will then be glad to pass that info on to AppleCare in trying to find a cause (and solution) for this problem.
If this issue was treated collectively maybe AppleCare would address it with more resolve & urgency.
I'll check back with this thread for replies from other interested users.

Lenovo monitor connected to Mac mini

I have a Lenovo LI2223s monitor connected to Mac mini - and works fine when from full start up. But when has been in 'sleep' mode overnight, does not display any longer upon wake-up. Is there something I can do to correct this problem? (waking the monitor does bring up a very very dim light there somewhere - but general appearance of monitor is blank - mini is no longer sleeping)
