This is due to the b43 driver not fully supporting some WiFi chipsets like the BCM4312 properly. You can switch to the propietary, original Broadcom driver where everything will work as expected:

Although, note this is a propietary driver, if you care about opensourceness. It's very easy to install, though. It will also allow you to connect full-speed to 802.11n routers. (probably that's the issue)

zenitra,
I have followed the instructions contained in the wiki article. Wireless seems to be working well for now, aside for occasional fluctuations in signal strength.
Assuming this works, thank you very much for your help! If I start encountering other issues, I'll follow the instructions under 'known issues' in the article and/or explore other solutions.
Thanks again

Control de brillo teclas de funcion en Acer TravelMate P253 ( Debian Wheezy )

Para hacer que funcione el control de brillo en nuestro TravelMate con las tecla de función lo que tenemos que hacer es algo tan sencillo como modificar el archivo  (  con permisos de superusuario ) siguiente:

su -

password:

nano /etc/default/grub

eliminamos o comentamos esta línea ( yo he comentado, por si acaso ):

#GRUB_CMDLINE_LINUX_DEFAULT="quiet"

 por esta:

GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=Linux"

una vez modifiado, salvamos el archivo.

update-grub 

y cuando finalice el proceso entonces reiniciamos la máquina.
