Sudden quitting of application like internet connection and Solver

there are a couple of issues with my Mac Book Pro-early 2011
1. The modem based internet connection takes almost few minutes to get connected and to open the home page.
2. some applications like Solver and even the internet connection suddenly get disconnected with a message "the app quit unexpectadly"
3. Sometimes the applections won't quit for a while, needs to be forcefully quit.
My Mac software is:
Mac OS X-Lion- 10.7.3
Kindly provide the needed help
Regards
Jagannath

When you're waiting for something to quit, open up activity monitor (Applications > Utilities > Activity Monitor.app), click the 'CPU' column (click it twice if necessary, you want the arrow/triangle pointing downwards) and find the name of the process that's eating up all the CPU.
Post its name here and we'll tell you what to do next.

I receive the error, "No Internet Connection" and my Adobe Creative applications are crashing on a regular basis.

I keep getting the same errors with the damn Creative Cloud application on my Windows 7 machine, which IS connected to a LAN and IS actively connected to the internet at the time the error routinely appears in the midst of tasks. I have checked root certificates, manually checked my hosts file and run the tests outlined above to both Adobe addresses.
In fact, the error kept occuring while I was on an over 3-1/2 hour call with a very through and nice representative from Adobe who had remote screen access at the time (through Adobe connect) and could see the error repeatedly occuring!
Her comment, "This just happens sometimes with this application and there's not a patch for it yet", The problem I was having with Photoshop CS6 and Photoshop CC was so severe that I had to do a SYSTEM RESTORE which then started affecting other Adobe applications because Windows had erased part of the programs (or all of some programs) but Adobe's software saw them as still installed, that she had me uninstall ALL Adobe Creative Cloud applications using the Adobe Cleaner Tool and reinstall everyting from SCRATCH. She and I had tried numerous other ways to repair the problems I was having with updates not installing correctly AND constant program freezing, etc. before this taking this extreme step.
I'm a professional programmer / software / web designer, so I had tried for hours correct the issues the previous night and had tried once overnight to reach someone in Adobe support only to be told of over an hour wait time by the automation and not offered a callback.
Anyway, despite her best assistance this afternoon (and double confirmation that everything tested correctly), it has taken, so far, well over six hours to reinstall only a portion of what I need for my work and on a deadline because the application keeps reporting "No Internet Connection" and I have programs cued to install unattended. I am now way behind schedule on some design projects which MUST BE COMPLETED by deadline and require Adobe's software to be installed and function correctly.
Adding to this, Windows Explorer has repeatedly crashed after installing the damn Creative Cloud application and works normally when it's removed and "cleaned" ... and I've seen so many problems with the install system, etc. that I have to wonder what in the hell the company was thinking when this approach was launched?
I generally have liked -- and indeed loved -- some of Adobe's products in the past, but the recent experience has certainly been costly in time and disappointing.
Many other software manufacters integrate suites, perform updates and confirm licenses without such a buggy, time intensive and unreliable process -- including my own company.
Aside from complaining at this point, I wish somebody from Adobe would provide alternative install methods and / or a fullproof fix for this bug and some of the other installation bugs many of us experience. Any thoughts, advice, knowing that not only I -- but also the Adobe Support Staff Person accessing my computer LIVE -- tried the various "fixes"?

Branching this to a new discussion as the previous discussion was related to the inability to connect and download the installation software.
Rob it does sound like you are facing some connection and stability difficulties. Do you manage your network youself? I am a bit concerned by the fact that you have stated that you periodically loose Internet connection while completing certain tasks. Does this affect your ability to utilize the already installed Adobe Creative software?
I would also recommend reviewing your installation logs to determine if any errors occured during the installation process. Please see Troubleshoot install issues with log files | CC - http://helpx.adobe.com/creative-cloud/kb/troubleshoot-install-logs-cc.html for information on how to locate and interpret your installation log files. Please feel free to post any specific errors you discover to this discussion thread.

What do you mean it did not work! What were the results of the diagnostic tests?
Have you contacted your ISP to determine if the problem is on their end?
Have you changed your router channel? Sometimes this resolves wireless problems.

A network error has occurred. Check your Internet connection, and then try again.

I cant downlload updates in my mac, its been 3 months since I cant do it. it says: "A network error has occurred. Check your Internet connection, and then try again." Ive tried in differents houses, wifi, internet and it keeps telling me this. Does someone know what can I do? Thanks a lot!

Solution may be found if you search in the "More Like This" section over in the right column.

Failed to update please check your internet connection and try again later

every time I try to run a program that I have downloaded (like Trend Micro) or update my Comodo Internet security I get an error message failed to update please check your internet connection and try again later and I am connected to the internet I've closed Firefox and reopened and it still does it
== This happened ==
Every time Firefox opened
== this has been going on for several months

I was unable to connect to internet via any app. I have now turned my phone off and on again and all seems fine.
Thanks for your help.

NETWORK ERROR. PLEASE CHECK YOUR INTERNET CONNECTION AND TRY AGAIN

I've been getting this message when I try and play some
games...Flash 9.0.115 is required to view this content. Your
current version is 9.0.47. Please download the latest Flash Player.
But every time and try and download it I get this error
message NETWORK ERROR. PLEASE CHECK YOUR INTERNET CONNECTION AND
TRY AGAIN.
I've tried changing settings but nothings working, can anyone
please help me

I SOLVED IT!!!!! LATEST FLASH IS INSTALLED!!!!
Here's what I did:
Read the information in the service note about the ridiculously sensitive download manager (DM)
ID:
kb400530
It gives instructions about internet settings necessary for the DM to work on multiple browsers. I use IE 7. Some were really non-obvious, like windows need to have no constraints on size, position. Most have to do with security, Active X settings.
However even after I followed the directions, I got the same error message.
But I'd gotten the general idea of what the DM needed, and went back to my Internet Options, and made a couple of additional changes. I'm not sure which of these was responsible for the success, but I'm resetting them afterward anyway.
For all the settings in which they allowed Prompt or Enable, I chose ENABLE.
I set Enable (vs. Prompt) for Download signed Active X controls (not secure) - this prompts a security risk bar, which didn't interfere
I also:
Set ENABLE for Run components not signed with Authenticode
Set ENABLE for Allow previously unused ActiveX controls to run without prompt
Set DISABLE for Automatic prompting for ActiveX controls
Set DISABLE for Automatice Prompting of ActiveX controls
Set DISABLE for Use Pop-Up Blocker
Set ENABLE for everything in under Scripting section
Anyway, you get the idea. I was trying to give the poor software every break I could, and it downloaded with no problem.
And then, the acid test.....I tried the site that had crashed because of lack of Flash 10 - and it tna perfectly....
Take that ADOBE!!!!
I hope something equivalent works for you.

TS3297 Error message: 'Cant connect to the itunes store. An unknown error occured (-3212) please check you have an active internet connection and try again'. Help !

Can someone help me please ? I was using itunes (downloading albums etc) just half an hour ago. I had a pop up asking me if i'd like to download the latest version of itunes, which i accepted. When the update had finshed downloading, i then restarted my computer, as i usually would. Tried to re access the itunes store, and received the following error message: 'Cant connect to the itunes store. An unknown error occurred (-3212) please check you have an active internet connection and try again.
Needless to say, i have an active internet connection and cant see any reason why this would be happening, it has never happened before ?
Any help would be appreciated.

Very Slow Internet Connection and Backups

I have had a Time Capsule for some time now (1st generation) and it has caused nothing but headaches. I have put up with it for some time but I have a very slow internet connection and cannot leave Time Machine on or it bogs down my machine, so I only backup periodically. Specifics are provided below.
I have a poor internet connection to begin with. When plugged in directly either to my modem or through Ethernet to the Time Capsule, I get download speeds of ~ 2.9 Mbits/sec download, 0.7 Mbits/sec upload. When connected over wireless, the speeds drop to about 0.6 Mbits/sec download, 0.6 Mbits/sec upload. I feel like I am working on dial-up. I have both a Mac and a PC, and speeds are the same on both, so it does not appear to be a computer issue. I have played with various settings in the Airport, including how connected (b-n or n only), DHCP settings, etc, but nothing makes a difference. Any suggestions?

Welcome to the discussion area, bigbrianb!
Have you downloaded a utility like iStumbler to get a look at the signal strength and noise on your wireless network?
iStumbler will display most of the other wireless networks around you, so you'll have an idea of the competition for unused channels. Ideally, you want your network to be on a channel that is at least 4-5 channels away from any other network to minimize the chances of wireless interference. Is that the case there?
Your signal strength should be 50% or greater and noise less than 10% for a good quality connection on your network. Is that the case there?
There are more things to test, but this will get things going.

New iMac Cant Hold Internet Connection (and finds a lot of networks....)

Hello,
I have one of the new 20" iMacs released 8/7. My problem is that my iMac cant hold an internet connection and it finds a lot of possible networks to which it can connect.
I am certain the issue lies with the iMac because my old Powerbook G4 has no problems connecting to the internet and it is sitting literally next to the iMac. Furthermore, I actually had purchased an iMac about a week ago and that one had no problems connecting to the internet either. (I returned that one when the new iMacs were released.) So that means 2 Macs had no problems connecting to the internet from the same location yet this new iMac does.
One thing I have noticed about this new iMac is that it detects many more networks than my Powerbook or the iMac from last week. I live in Manhattan so there are networks everywhere. Sometimes the iMac will give me 15 or so different networks to connect to and seconds later the choices drop to 5 or so. When I try to connect to the network I want (my network) the connection doesnt hold and it frequently drops. It takes me forever to download anything. I have to write this post on my Powerbook. My Powerbook only detects 2 or 3 possible networks to connect.
I rebooted, etc. and that did not work. I shut the Powerbook down so that it would not "compete" with the iMac and that did not work either.
Any suggestions/ideas?

Hello Wireless groupies:
I have had wireless problems with my laptop and my power mac this week, but all is well for me now.
The grass roots issues of wireless communication in terms of physics are related to amplitude and frequency. The amplitude is controlled (signal strength) by the power setting of the router and the portable device. The amount of power in the signal is measured in watts per square meter and is controlled by the broadcasting units settings.
The frequency at which the router broadcasts is changed by channels available in both units. I believe the portable units scan each channel for base station transmissions just like the radio in your car/lorry . The frequencies associated with each channel on the base transmitter can be assigned by the user for the best reception in the local broadcast area, most likely your home. The area which you operate has many different interference parameters which degrade signal strength just as in your portable radio reception. In the base station world it is based upon digital transmission encrypted (D to A) into an analog signal then decrypted at the laptop from analog to digital signal.(A to D). Experimentation is probably the only method to determine which is the best frequency to operate between your devices.
It should be noted that the new Imac's have an extended frequency range because they use a 'N' class wifi set of components. The N class wifi allows for higher frequencies and extended ranges. A base station which is a G class wifi can only broadcast in the lower frequency range and hence the availability of the higher frequencies of the new Imac are irrelevant because the Imac must receive only what is is transmitted in the 'G' range, 'N' class reception and hence the benefits of higher frequencies are not available. The only solution is to have 'N' class devices through out the network, otherwise everything reverts to the 'G' class range of lower frequencies. The solution to extend the frequency range of the network is to upgrade ethernet cards and base stations, so that 'N' class frequency transmission can be utilized.
The network will work with 'G' and 'N' devices but the network is only as good as the lower class device of transmission and reception.
I would start by getting an extreme network airport base station and then experimenting with different channels at a midpoint power transmission. The best frequency would be one which delivers the most power at a set power transmission level (signal strength). The higher the frequency the greater the penetration through walls, beams, people, dogs, cats, pipes, tabletops....:). I would then experiment with the power levels for the range which you want to cover, most likely just your home and not your entire neighborhood.
In my house I use channel 6 and power level 5 from a 2wire gateway/router, which is in the G extreme class range. I have always used channel 6 but I have tried power levels 3, 4 and 5. The biggest interference variable being weather and cordless phones. The cordless phones operate in the 2.4 GHZ range and the 900 MHZ range. The phone directly above my router is a 900MHZ phone and it never interferes with the 2.4 GHZ wifi network. I think the worst phone to have with a G class network are the 5.4GHZ phones because they actually use some of the same wireless bandwidth. A 'N' class network would probably be a better choice if you want to use a 5.4GHZ phone system.
good luck

While downloading app update on ipad lost internet connection and now the updates are not updating. How do I fix this?

While downloading a common application update, I lost my internet connection and now the updates are not updating. How do I fix this?

Try this:
• Log out of your iTunes store account. Go to Settings > Store > Sign Out Then press the Home button.
• Then press and hold the Home and Sleep buttons simultaneously and don't release them when it brings up the Turn Off screen; keep holding them until the Apple logo appears.
• Then restart & see if you can update.

Most likely not, but since you haven't provided any proper system info and other technical details like what internet connection you actually use we can't advise specifically. Start by reading this:

Using Remote app on iPhone 5 without a separate internet connection and wifi router.

Hi,
I need to be able to control iTunes within my MacBook Pro remotely. Using my mobile broadband service and wireless router I've been able to get the Remote app to allow my iPhone 5 to do the job nicely through Home Share. So I went and bought a separate WiFi router and tried to do the same thing. Of course when it didn't work, I discovered that I need an internet connection and WiFi network to make the Home Sharing work.
So I got to thinking, can I create a WiFi hotspot using the Personal HotSpot functionality of my iPhone, set up Home Sharing on phone and MacBookPro and then use the Remote app. Ideally this would work as it seems all the key components are in place.
The MacBook Pro accepts the iPhone hotspot as a means of Home Sharing, however the iPhone won't use the personal hotspot to Home Share and I can't connect to the iPhone personal hotspot on the iPhone itself.
Does anyone know how to make this work for me? It would be such as neat solution if I can get it to work - not to mention the potential to save me about $200 (I need to set this model up for two people).
Cheers
Kathy
