Interesting.... Looks like the EEPROM part of TP-LINK routers is somehow neglected... However, if I got it right, you only need to recompile the firmware if you want to use channel 12 and 13. To restrict your TX-power to 100mW (instead of 500mW allowed in FCC-land) you can just set the country code in UCI. So by default, this just *prevents* you from using channels you are legally allowed to use in your country. Using the binary from downloads.openwrt.org won't give you access to bands which are restricted by law, right? Not that this is any better, but chances to get into trouble for accidentally using reserved frequencies are much higher than for just using too high TX-power... _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
