Public bug reported: I have an ASUS PCE-AC68 adapter (BCM4360 chipset), running under 13.10, kernel 3.11.0-13-generic x86_64, bcmwl-kernel-source 6.30.223.141+bdcom- 0ubuntu1. The AP supports 802.11a/b/g/n/ac.
The card and adapter work perfectly when connected in the 2.4GHz band and 5GHz low channels (36-48). When connecting at 5GHz high channels (149-161), there are no obvious errors, but packet loss to the gateway is extremely high (50-80%). This behavior is very bursty, alternating between no, and total packet loss on a timescale ranging from a few seconds to a few minutes. Power management is off, and syslog/kern.log don't provide any useful clues. Based on the observed pattern of the packet loss, and the performance of other 5GHz devices connected to the same AP, I don't think it is an interference issue. I'm unsure as to how to proceed with generating some more useful logging, so any suggestions would be appreciated. ** Affects: bcmwl (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1256158 Title: BCM4360 High packet loss at 5GHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1256158/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
