Can I get a little help with the network disgnostics app please?

[the8thark]

What does it mean when the bottom two buttons, internet and server are yellow (or sometimes red) as shown above?

When the above occurs my internet speeds drop to a crawl, even the Apple startpage takes ages to load up when at other times it loads near instantly. Also when I clock next continue and choose my Wi-Fi network the app asks me if it can access keychain? I click always allow but every time it keeps asking me for this access. Why?

Also after I click accept keychain access it all goes green (most of the time and it's fine) sometimes for hours, sometimes for minutes only when the same thing happens again.

Can someone please explain this to me so I know what is going on so the issue can be fixed.

How are you physically connecting to the internet?
Through a cable modem?
Through an optical connection?
Through DSL over a phone line?
How?

Have you tried the "Automatic" choice? (DHCP, I believe it's called)

DSL over phone line to Airport Express which is inturn Wi-Fi to my iMac.[/QUOTE]

Yes and the exact same issue.

 

[Mr_Brightside_@]

Can you plug directly into the modem?

Can you plug directly into the modem?

Not at the current point in time. I bought the Airport Express for this exact reason.

 

[Mr_Brightside_@]

It seems like the AirPort is broadcasting a signal, but not actually providing an internet connection. Change the location to Automatic in System Prefs>Network, then apply and close System prefs. no change?

You have a DSL modem, right?
What connections are on the back of the DSL modem?
It has an ethernet port on it, right?
(How else could you connect to the Airport Express?)
How is the Airport Express connected?

Another important question:
Is it a DSL "modem" (only)
or
Is it a DSL "residential gateway" (a COMBINED modem+router)?

A DSL modem will probably have only one ethernet port on it.
A residential gateway will probably have 4 ethernet ports (as do most routers).

 

[Mr_Brightside_@]

Why can't you plug in? You have an iMac. Would you have to move it?

 

[flashy-cat]

Check you haven't got two devices with the same IP address on your network. That can cause all sorts of connectivity issues.

 

[Tech198]

go under Network in System presences, and under "Location" choose edit (may have to unlock system pane first)

then add a new location, save and Restart mac. By creating a new location and using that instead, just to solve any issue issues. Boot into safe mode (hold down SHIFT at boot till you see Apple logo), or create new user and login to *that*

Correct. I don't have a long enough ethernet cabble now to hook the iMac directly to the router.

I will chack that and get bavk to you.

Another important question:

It's the 2nd option. Has 4 ethernet ports on it.

 

[Fishrrman]

Use an ethernet cable to connect the Mac directly to one of the ports on the residential gateway and see if you can connect to the net that way.

If you have to move the iMac to do this ... move it.

Can you connect to the net this way?
