I have no knowledge of the openELEC distro, or more precisely, what kernel they are using, but r8712u works very well with current kernels such as 3.4-rc3. There were some changes added between 3.1 and 3.2 that caused problems with some distros - Arch and Debian were two of them. If yours is Debian based, then it is probably affected. Those problems were fixed and have been added to the latest releases of stable kernels.
In short, you probably need to upgrade your kernel. Larry -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
