Slow Internet in Leopard 10.5.7

Question

I just updated my 1.83 ghz macbook pro to the latest version of leopard. After which my internet is noticeably slower than it was under 10.4, to the point where it makes loading videos on hulu or youtube impossible and doing any sort of web browsing difficult. Google has many different causes. Any idea what I may be looking at?

It was an install to a brand new hard drive. The router has the latest firmware.
But how old is the router? And not all routers work well with Leopard. Only those with the latest security features.
After trying to go thru the other suggestions, most of that sounds way over my head. Its really quite frustrating. What changed in airport from 10.4 to 10.5 that caused this?
Security. When Leopard came out many of us had to update router firmware or replace the router.
The usual complaint was, "It worked with Tiger and my XP but not with Leopard."
Right now this MBP connects at 20 Mb/s same as Tiger and same as my PCs.
I use two modems, a Verizon MI424WR Rev. E and a LinkSys WRT54GX2, all with the very latest firmware. No problems with either. No connection speed problems, no dropout problems.
It's not Leopard, it's usually router incompatibility.
You can also visit

and see your actual speeds, separate from the initial delay or latency.
DNS is usually the culprit when latency is an issue, but never when the basic speed is the problem
