Droppin Internet Connection

I am using OS X 10.8.2 on an iMac 21.5 inch, Mid 2010.

For quite some time the internet becomes disconnected. I run windows XP via VMWare Fusion on which I run StreetSmartPro. StreetSmartPro continuously updates info from my brokerage account. When the internet is dropped, the messages I get on Windows are: "Local Area Connection: A network cable has been disconnected", "Error connecting to Main Server: Connection to trade server has been lost".

When I am running StreetSmartPro on Apple from Safari, when the internet connection is lost, the message is something like "internet connection lost: would you like to reconnect".

Yesterday I recorded the disconnects for several hours: 11:44 am; 12:09 pm; 1:50 pm; 2:41 pm; 3:23 pm; and 4:15 pm.

My Provider monitored the connection from their offices all the way to my computer for an entire afternoon. When internet seemed to be dropped for an instant, they saw no evidence. Their records showed that the connection was constant. His theory is that there is a problem within the computer.

Anyone out there with any suggestions?

In Fusion, are you shharing the Mac's connection, or what setting??

The interface that connects to the Internet should be dragged to the top of the list.

Is that Interface dragged to the top of Network>Show:>Network Port Configurations.

If using Wifi/Airport...

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

I am sharing Mac's connection with Fusion.

Just so I follow you, I am using 10.8.2, therefore I follow instructions on support.apple.com/kb/HT5289:

System Preferences>Network, top of window>Locations>Edit Location>, little plus icon, give it a name.

I am not using WIFI. I have DSL via Ethernet.

Now, if I follow these instructions, I am not going to mess something up, right?

I followed your instructions as I repeated them above and everything seems to be working fine. I will have to wait until tomorrow to see if the disconnect problem has been resolved. I will report back either way.

Thank you.

Today connection to the internet continues to drop, so establishing a new location didn't work.

The disconnect only lasts seconds until I am again reconnected.

Any other ideas? Is there a possibility I need a new Network Interface Card? Or that it involves another computer fix?

A new network card costs a mint, requires a new logic board on an iMac. 😟

I don't think that's it yet though, either Router, or we need more clues...

Open Console in Utilities & see if there are any clues or repeating messages when this happens.

Regarding the cost of a new Network card, I still have an extended warranty and I want this diagnosed before it runs out.

I don't have a router. The fiberoptics DSL cable is connected to a small box on the wall (about the size of a pack of cigarettes and is conected to my computer via an ethernet cable.

Wow, a whole bunch of things appeared in the Counsole.All messages the moment the internet connection disconnected. It is beyond my expertise to decifer it. I'm not able to print or copy and paste the info. How can I pass the info on to you to look over?

I don't have a router. I have DSL via fiberoptics...there is a wire that runs into a small box (about the size of a cigarette pack) attached to my wall. The Ethernet cable runs from that box directly to my computer.

I had the same problem when I upgraded my 2009 24"iMac from Snow Leopard to Mountain Lion. I spent hours on the phone with Apple support and they had no solution. I did some research and found that possibly Safari was the culprit. Any awy, I installed Google Chrome for my search engine. I have now had no disconnects for 2 weeks. Maybe magic, maybe a fluke, I am not sure, but...
