Mac Pro Internal Airport vs. Laptop Airport Signal Issue

[martinvanderhof]

I have a strange issue.

I am able to connect to my wireless router with my laptop airport (powerbook G4) and receive a good signal. 3 or 4 out of 4 bars.

When I place my Mac Pro desktop (Early 2009) in the same spot and turn on the airport, it can barely connect to the same network (extremely weak signal) and it drops out constantly.

Does anyone know why this might be, or what I can do to fix it?

I'm sharing my laptop connection to my desktop at the moment, but I'd rather not have my laptop on all the time. I can't really move my desktop or the router either - I live in a guest house, and the router I connect to is located in the main house.

Thanks in advance for the help, everyone!

Easy. The Mac Pro has the Airport card deep inside a metal case whereas the laptop has it at the top of the screen.
Less material to go through means a stronger signal.

Don't forget that the "bars" are not a good indication of actual signal strength.
