I just purchased a LDF 5 (RDLDF-5nD-US) after an update to routeros 6.46.4 I lost all 5Ghz channels below Channel 151 (5745MHz). Is there any way to get them back as I have a access point here on Channel 36. According the the website the LDF 5 US (USA) is factory locked for 5170-5250MHz and 5725-5835MHz frequencies.
