Comment 39 for bug 1666432

Hi.

I am just a fellow Ubuntu user, but I am afraid this bug report is most likely not something anyone could solve, because so many different chipsets and issues are being discussed here (I assume this is also why no developers felt inclined to touch it so far).

I very much recommend that anyone still experiencing wireless issues should (look for, and if none exists) file a new bug against their wireless driver, and anyone with Ethernet issues should (look for, and if none exists) file a new bug against their Ethernet driver. Your drivers will usually be listed in the output of one of these commands:
lspci -knn
lsusb

You are also welcome to check back with community support to check whether a fix (or a workaround) is already available for your very issue, or just to get help with filing a bug report that is specific and can get handled more easily.

If TylerKinkade's issue (where both Wireless and Ethernet disconnect at the same time, on a now supported Ubuntu version) persists then it is more likely a platform (hardware / mainboard / ACPI / firmware) specific issue and should be treated as such, affecting Inspiron 5567 with this specific Ubuntu version (was 16.04.1 originally).
