network connection is randomly disconnected after sleep.

I have a iMac OS X (10.5.8) I purchased in 2009 brand new. For the last 6 months, I have to go thru network diagnostics to verify my network name and re-enter my password for the network. I have an Ipad, Ipod, and laptop PC that have no issues connecting to the network after I have contacted my network to troubleshoot problem, it is not the network. My system software is currently up to date, I did notice that 10.7 Lion had a software update for this problem that I am experiencing. Can anyone give me a solution to troubleshoot this problem?

iMac, Mac OS X (10.5.8)

Possible fixes...

Make a New Location, Using network locations in Mac OS X ...

http://support.apple.com/kb/HT2712

The Interface that connects to the Internet, needs to be drug to the top of System Preferences>Network>Show:>Network Port Configurations and checked ON.

10.5.x/10.6.x/10.7.x instructions...

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

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

You haven't provided much information but where I'd start is by resetting the modem & router, then from there check to see if you are competing for channel bandwith with your neighbors. Download and install iStumbler (Google it) and check to see what channel you and the neighbors are using, let it run for 30 minutes or so. If you find you're all using the same channel then change it. If you aren't competing for channel bandwidth then reset your DNS settings from the defaults your ISP provides. You can do so by:

1. System preferences

2. Network

3. Click Advanced

4. Click DNS tab

5. Click + sign

6. Add 208.67.222.222

7. Click + sign

8. Add 208.67.220.220

9. Click OK.

10. Exit System Preferences
