Difficult to report when wifi is down! Happens sometimes after a few minutes, never more than 30 minutes. Easy to capture journalctl when the network connection hangs. Intel fails on 2.4 GHz or 5 GHz, using several different AP's. The same system runs stable and perfect with a USB dongle Realtek RTL8188CUS, but I have to blacklist iwlwifi in /etc/modprobe.d/modprobe.conf to prevent iwlwifi hanging all network activity while simply scanning and not connected to an AP. I've had similar problems with this system under 17.10, but it has become more reproducible under 18.04. I've back-levelled the driver as far as possible, but they all hang the network. Because version 29 firmware is the latest in the bionic repository, and also on the intel support web site, I won't confuse matters by reporting earlier ubuntu kernels or iwlwifi versions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1776443/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
