I own an iMac OS X and the Internet is having problems. Randomly, the DSL disconnects. When it connects again, I have to turn off WIFI and turn on again. When I play online games like Minecraft, it disconnects. Is it the internet or the iMac?

G'day and welcome to the forums.

Sounds like DNS address problems. What model iMac and what version of OS X? When online go into Network > Advanced > DNS and check out what it says there. You may find it nec essary to change to say Google DNS of 8.8.8.8 Primary and 8.8.4.4 Secondary. Also have a read of this thread:-

Slow Internet with mac but not PC

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

It sounds more like interference to me. DNS problems generally cause the slow loading of web pages but not intermittent disconnects. At least that has been my experience.

Are you in close proximity to other networks? Living in an apartment building? Do you own a wireless telephone at home? All these can cause interference and the intermittent loss of signal. Download the free iStumbler utility and run it. It will show other networks in your area and the channel and security they're using.

Report back the results and we'll try to figure something out.

Charlie I thought iStumbler was OS X.6 Snow Leopard only, apart from a beta version 100 for Lion which is untested? Is there a later release I am not up with please?

I'm using iStumbler with Mountain Lion Harry. All it says in the "About" is that it's release # 99. Here's the download LINK

Works great. I just tested it again to make sure.

That information is not what we need. Take a look at my example screenshot and post the same thing from your copy of iStumbler.

Also, can you tell us WHAT the pictures above are (not you, chscag)? Is that your WiFi router, and your router is connected to a DSL modem? Or is that a DSL modem/router combo device? The red internet light might tell us something IF we know what device we're looking at.
