Default (BCM4312) Fatal DMA error

I am having a problem with the bwn driver in FreeBSD 11.1.

After some minutes of being connected or sometimes instantly it will disconnect and will not go back up again, spewing these errors ...
Code:
Aug 29 00:42:06 minger-pc kernel: bwn0: Fatal DMA error: 0x400 0 0 0 0 0
Aug 29 00:42:06 minger-pc kernel: bwn0: HW reset: DMA error
Aug 29 00:42:06 minger-pc kernel: bwn0: ucode fw: ucode15
Aug 29 00:42:06 minger-pc kernel: bwn0: firmware version (rev 478 patch 104 date 0x8701 time 0x657)
So far the only "solution" in sight is to reboot.
I have tried many things to fix it without rebooting but it's not happening.

I have also tried to set hw.bwn.usedma to 0, but all that does is render my wireless device unusable, spewing these errors endlessly ...
Code:
wlan0: Ethernet address: 00:22:5f:28:b2:53
bwn0: ucode fw: ucode15
bwn0: firmware version (rev 478 patch 104 date 0x8701 time 0x657)
bwn0: incorrect CCK rate 117
bwn0: bwn_rxeof: dropped
bwn0: incorrect CCK rate 213
bwn0: bwn_rxeof: dropped
bwn0: incorrect CCK rate 30
bwn0: bwn_rxeof: dropped
bwn0: incorrect CCK rate 213
bwn0: bwn_rxeof: dropped
bwn0: incorrect CCK rate 45
bwn0: bwn_rxeof: dropped
bwn0: incorrect CCK rate 30
bwn0: bwn_rxeof: dropped
bwn0: incorrect CCK rate 59
bwn0: bwn_rxeof: dropped
I am loading the firmware for this.
