Here in The Netherlands, it is quite common to use a US version of Windows and to keep (most of) the regional settings of the US. So on Windows, most of the time the region is likely to be wrong. I gues that in cases where things are critical, a different firmware version is used. It is not really a practical problem however, because the allowed frequencies have become pretty the same over time. The same applies to modems: they are also country-specific. But in practice, it is not really a concern. But how to go furter with this? Does someone have contacts within Broadcom?
