Internet Dropouts and Internet Connection Trouble; POSSIBLE SOLUTION

Question

Here is something that might help
I have had problems with this on my old G5, Intel Macbook, and More Recently my Mac Pro (past 4 years I have airport trouble)
I spent hours trouble shooting, the thing that ends up working for me three times so far has solved my problem
Here is a step by step instruction of what I did (continue anyway if you are not receiving the same circumstances/results)
Remember this is also a diagnostic method for yourself to see what is working and what is not so you can solve the problem. Also I still get network drop outs and sometimes internet performance decrease but a lot less frequently by performing the steps bellow. If your problem persists then I might be able to trouble shoot with you. In no way this method will be successful and your problem may become worse so use discretion when applying the steps below
1)Check "Console" to see whether broadcast is being dropped (utilities folder)
2)Make sure your problem persists with all other applications not running (including your virus software)
3)Reset Safari and continue loading to see if network performance is still hanging up
4)If slow loading persists/airport drops shut down computer and boot into safe mode by holding shift key (this empties cache stuff and does a few repairs)
5)Load Safari and see if slow loading persists (while in safe mode)
6)Go to disk utility and repair disk first (or verify)
7)If disk comes clean then precede to repair permissions, there are many errors that show up that are nothing to worry about "ACL found in different place" is one of them.
8)Shut down, (do not restart and wait for 10 sec, I have no idea why this happens and it does not make sense to me but I have restarted and ended up with some other problems)
9)Turn on computer and proceed to disk utility again (do not worry about airport, do not touch yet
10)Verify disk again (remember not in safe mode)
11)Repair permissions once again (different things are loaded into the permission system; plugins ect.)
12)Shut down computer again
13)Turn on computer and proceed to open network preferences and remove airport service (make sure your changes are applied)
14)Open key chain access
15)Delete your network password (if it exists) in "login" and in "system"
16)Shut down computer once again
17)Reapply all network configurations in the network preferences panel
18)Shut down computer once again and turn on
19)Check airport performance over the next 30 min or so by clicking links actively and waiting
20)If problem persists you may have corrupted files somewhere and may have to delete some preference files and perform the method above once again (to be safe I suggest running the disk utility test once again)
note: for some reason Leopard still remembers old network information even after deleting it. you need to find a way to keep leopard from using old preferences (it can be any of them). If all thus fails trash your router settings (on your router, factory defaults) and perform the steps above once again)
Please report abnormal occurrences like the "self assign ip address problem in network preferences" so we can narrow down where problems are mostly occurring"

I quote from the System Preferences Help:
If your computer is connected to the Internet, you can share its Internet connection with other computers on your local network.
For example, if your computer is connected to the Internet using a DSL modem and has an AirPort Card installed, you can share the DSL connection with other AirPort-equipped computers.
On Windows computers, sharing your Internet connection is sometimes referred to as a “network bridge” or “bridging your network.”
To set up Internet sharing:
Choose Apple menu > System Preferences and click Sharing.
Select Internet Sharing.
Choose the Internet connection you want to share from the “Share your connection from” pop-up menu. For example, if you’re connected to the Internet over Ethernet, choose Ethernet.
Select how you want to share your Internet connection in the “To computers using” list. For example, if you want to share your Internet connection over AirPort, select AirPort.If you share your Internet connection using AirPort, click AirPort Options and give your network a name and password.
