Which router has conflicting country codes?
Using the Wireless Diagnostic tool in 10.8.4 tells me that:
"Conflicting Country Codes
A nearby wireless router has been detected which is identifying itself as originating from a country which conflicts with your current settings. This may prevent your Mac from automatically re-joining a previously joined Wi-Fi network.
Certain wireless routers have the ability to identify the country they are designed to work in, this is called the Country Code. Wireless routers should only be used in the country they were originally obtained from. Failure to do so can result in performance and reliability issues for nearby wireless clients."
There are typically between 6 and 8 wireless routers other than my own that my iMac detects, some of them with good signals. How can I tell which is the offending router and is there anything I can do about it? My own wireless router (a BT Homehub3) does not appear to have a country code (or if it does, it is not obvious or can be changed). Most of the other routers detected are also BT devices.
