Broadcom BCM43602 does not see 5 gHz networks on Ubuntu 16.04

[Alexnader Karenin]

Dear team.

I am using
02:00.0 Network controller: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC (rev 01)

with Ubuntu 16.04 and linux-firmware version (1.157.8).

My system can scan and connect to 2.4 gHz wifi network, but could not see any AP's on 5 gHz.

Found that bug report https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1487524 but it is not of much help. Situation exactly as in post 12.

I can't find any solution (
