Ok, now this is interesting. Looks like probably not a kernel bug but perhaps network manager?
Installed the updated upstream kernel deb, suspended, waited, woke the laptop. I'd been assuming the network was broken because (as you can see from the screenshot) network manager shows no connection to wifi) (although oddly it shows a wired connection when I have no cables attached). So it seems not a kernel bug after all. ** Attachment added: "Workspace 1_003.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1570595/+attachment/4637130/+files/Workspace%201_003.png -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1570595 Title: Intel 7265 wifi drops and won't reconnect Status in linux package in Ubuntu: Confirmed Status in linux source package in Xenial: Confirmed Bug description: My my T450 has Intel 7265 wifi. Sometimes it just seems to disappear from network manager. I end up having to rmmod the iwlwifi module and re-add it to make it see wireless access points again.
