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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1630324 Title: Broadcom wifi dies in 60s cycles with 4.8 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1630324/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
