I've got the same issue with my Dell XPS-15 (9550). The chip is BCM43602.
I've flashed my router (Archer C7 v2) with dd-wrt (ftp://ftp.dd-wrt.com/betas/2016/11-01-2016-r30826/tplink_archer-c7-v2/), configured 5Gz network as follows:
Wireless Mode: AP Wireless Network Mode: AC/N-Mixed Channel Width: Full (20 MHz) Wireless Channel: 40-5200 MHz
And the problem is almost gone. The connection is fast and stable, but I still getting error about ISO code.
