Sorry, actually it was iwlwifi-3160-15.ucode and then iwlwifi-3160-14.ucode that I tried which both worked better than the default (since it's the highest revision) which is iwlwifi-3160-16.ucode.
@Seth - I tested that package, confirmed that version 17 got loaded, and initially it seemed to work better. I was able to detect and connect to my 5Ghz network right away, and iwconfig shows the connection's bitrate at 72 Mbps, which is what I'd expect with this card as it's 1x1:1. However, when I launch Kodi and it starts picking up my network shares, it's very slow to load the art assets (box covers, movie posters, etc.) and if I try to play a video it hangs trying to launch. Lower b/w-demanding tasks work ok - I can ssh into other machines on the network, and apt update/upgrade seems to work ok. It's like once the you start a sustained, moderately high data stream it either starts dropping packets or the bitrate drops. Also: in order to even detect 5Ghz networks, I had to add "option 11n_disable=8" to /etc/modprobe.d/iwlwifi.conf. I just can't wrap my head around why it would have worked excellent through 15.04, then 15.10, but suddenly isn't working on 5Ghz at all... it seems like quite a regression! Anything else I can try or other data points I can provide? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1602051 Title: 5Ghz link no longer works on 16.04 - iwlwifi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1602051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
