Hi everyone
I got a problem here and I need some help 
My device is 1900ac v1 ''mamba"
A few days ago, I reinstalled the whole system because of a software corruption. But after reinstalling and rebooting, the 5G disappear. There was only one radio Marvell 88W8864 802.11bgn. I have tried reinstalling the official firmware. But even if I switched on 5G(there was 5g switch icon in official firmware)in webage, there was no 5g signal. Also, I checked the kernel log.
