Airport Extreme slower than Linksys router?

[OceanView]

I just bought an AE and replaced my older Linksys with SpeedStep router and for some reason the internet seems slower.
I did a speed test to compare with my older system and it's night and day how much slower it is now.
With the Linksys I was getting from 10-15Mbits download.
With the AE I'm just tested and got 700KB down
Anyone have a clue as what I can do to speed it up?
By the way, the AE is connected directly to my desktop by ethernet cable.

Oh I've also noticed it runs pretty hot to the touch, is this normal?

How about bypass the AE device and plug your mac directly into your WAN modem. Perhaps your ISP is slow today.

I retested today and it seems that it's back up to speed now.
I just got 15MB/s

The Airport is still pretty warm to the touch.
That's the only negative for now otherwise happy for now.
