Note the steps to do so at the end of each stage try to test Safari, this training is complete and to resolve all problems.
Go to disk utilities and run repair disk permission .
go to Keychains and go to the first aid, then run the repair option.
From within Safari, the safari menu, reset safari options and Run.
Go to system preferences, network, advanced options and dns tab, use the following dns, 209.244.0.3, 209.244.0.4, 8.8.8.8, 8.8.4.4, and then click OK and click apply, then open Terminal and run dscacheutil-flushcache command,
If none of above works , this will 100% work, go to terminal , note that this will erase all safari data and bookmarks, run command below
Code:

well friend, thanks again for all your help. i found a lot of help on another thread if you're interested: http://discussions.apple.com/thread.jspa?threadID=1195713&tstart=0
regardless, here's some things i did that seem to have helped for now... significantly speeding up my web browsing:
1. I changed from WPA/WPA 2 to just WPA 2 (this seemed to have helped the most)
2. I added two 'general' DNS addresses in my preferences/network settings (this also seemed to help):
208.67.222.222
208.67.220.220
3. under my preferences/network settings, I completely turned off Configure IPv6. (I don't know if this has helped but it was suggested and it doesn't seem to have hurt)
Unless I'm connected to a cisco client, I still have very slow to no browsing on the apple discussions pages but all other pages seem to be working now without cisco.
until next time.
