I have serious problem with my D53G-5HacD2HnD (7.18.1). Yesterday I have updated modem firmware to latest version RG502QEAAAR13A03M4G_02.004.02.004 with result that device is not picking 5G network anymore, only 4G. Before update it was working normally within 5G NSA. Is there any way how to restore previous firmware, to be completely sure it is really caused by this version? I hope it was RG502QEAAAR13A03M4G_02.003.02.003
I’m still getting 5g on my Chateau 5g with latest modem firmware and that’s with Three in the UK. It’s aggregating B1 B3 N78 N78.
