Mac Mini - Network connection fails (Internet and Server)

Thanks for the quick reply BDAqua.

Unfortunately that didn't help - I'd tried that previously.

The problem exists with both wifi and wired/ethernet connections. The Mac Mini does get an IP address from the router but then doesn't go any further.

I have tried flushing the DNS cache and that hasn't helped either.

The router has been restarted numerous times to attempt to clear this issue.

Thanks for your time and effort.

Unfortunately that's a no-go too.

I typed the IP address in the Safari address bar and it correctly resolves to www.apple.com but Safari error page updates to say "www.apple.com is unavailble" (or words to that effect).

So this appears to suggest that there isn't a DNS error.

David

Hi,

I tried again and it didn't resolve the IP address to Apple.com. No, it didn't display the website, but the Safari error page.

There have been no changes to the router. The Mac Mini has operated with the router and all attached devices for the past few years without any issues.

Just tried the TraceRoute and Ping utilities. It'll ping/trace to the NAS-device on the network but it will NOT ping/trace to an external web address.

I have now updated my Router to force DNS servers on all devices connected to the LAN. They now all use Google's DNS. All devices continue to operate correctly apart from the Mac Mini - this continues to have the same problem.

The Mac Mini is now showing the two Google DNS IP addresses in its DNS preferance pane.

However, there remains no Internet connectivity nor connectivity to the AFP drives on the NAS.

Another thing to note: this is happening on wireless and wired so that's connecting to the router via two different MAC addresses from the Mac Mini. This, to me, suggests that it there's something wrong with the Mac Mini and not the router nor the Mac Mini's method of connection. Very strange.

The Mac firewall is not running. I've even turned it on and then off again (read that might help elsewhere here) but no change.

I've created new 'Locations' and moved and deleted connections and priorities. Nothing.

I've tried reseting the SCM. Nothing.

All other devices continue to operate on the network correctly.

Okay, update as of 17th May:

Had Apple Support on the telephone last night for over an hour trying to sort this out (paid for single event support). No success. Basically did everything you had already advised/said. The tech guy was raising it up a level in the support team and they 'were' supposed to call back tonight but they haven't.

Have now had to put another support call request in for tomorrow.

Frustrating that Apple failed to honour their commitment to call back tonight.

David

😠

Two calls from Apple Support today - one on-time which I scheduled via the website, and one which *may* have been the one the first Advisor had arranged (or put me into a queue for).

No resolution yet. I've been advised to reinstall the OS. Unfortunately I cannot find my installation disc so Apple are kindly sending me a new one in the post.

I'll advise on progress to ensure that anyone else with a similar problem will have something to follow...

David

Apple were true to their word and sent me a replacement OS X disc via TNT. I reinstalled the OS (without erasing or reformating the drive) and the reinstall appears to have fixed the problem!

I now have access to the Internet and things appear to be working as normal. I'm happy.

So, the fix: reinstall the OS.

Thanks BDAqua for your help too.
