How can I use WiFi channel 13 on a US MacBook?

Question

Hi there. I own a MacBook 2.4Ghz, have been using it in the US for a while and everything worked just fine, WiFi included. Now that I find myself living in Europe for a couple of months, problems arise. The WiFi I'm supposed to use is on channel 13, and there's no way I can change it. I read that channels 12-13 are not allowed in the US, and that's probably why my MacBook doesn't detect it, whereas my European iPhone always does.
My question is: how can I "tell" my Mac to use this connection anyway? It's technically able to detect it. KisMac finds this connection showing its channel (13), so there must be some setting that prevents me to use it because it's illegal in the US.
Any help would be really appreciated

Those combinations work on my G4 iBook (which is even older than you Macbook) and they work with my Mac mini with the aluminum Apple keyboard (which is newer), so they should work for you.
When using a modifier key like fn, you have to hold the modifier key down, then press the second key. That is, the fn key must be down before the arrow key is pressed and it must stll be down when the arrow key is pressed.
I imagine you know that.
Do the arrow keys work normally, for example to move the cursor in text?
Does the fn key work for other things (fn - delete to delete forward, for example).
Have you looked for settings in Systems Preferences > Keyboard that might affect this (I don't really think that any should) or might you have any third party software that would affect keyboard input?
