Safari idle when not use for one hour that causes no connection

[webexplorer]

I am not online for one hour, then I came back to look up on the internet. My Safari cannot connect online. I logout the OS and entered my password to see if the online might come back. No luck.

I restarted my computer, and everything is fine with online. I also checked with the System Preference for Network, and the Ethernet shows a "green symbol" on the display which means that the connection is working.

I do this all the times. Does this happen to you? Why is that?

(Off record, does my iMac wants me to insert my coins in the card slot in order to connect online?)

When your connection drops next time - go to your System Preferences, then Network.
Click on the Assist Me... button (at the bottom of the network window)
Click on "Diagnostics"
If your network connection is working, the "Network Status" will show all green.
If some are yellow (or red), then your connection is not completely working.

If your connection is sometimes dropping out, and you are presently using the "Automatic" location, then you can try making a new Location (in your Network pref pane), and making sure that your connection type (Ethernet) is correctly set up. Then, select that new location. That sometimes will help maintain a more stable connection.

I think not, but do let us know what happens, worth a try. A new way to finance the interwebs?

(Be sure and submit Apple feedback.)

I have said this many times, i think this is very much related to mDNSresponder being a bit crap and the OS losing DNS resolution.

Here is a script wrapped into a command which will restart the process and often will get you online without a restart. You woudl just need to eneter an admin password to run.

here si contents of script.

#!/bin/sh
#Script to unload and reload mDNS as it is a bit crappy
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
echo "mDNS unloaded"
sleep 5
sudo launchctl load /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
echo "mDNS loaded"
sleep 5
echo "Hopefully you can get on with browsing again"
exit

Any clue why this happens to some machines and not others?
