Issue with networking after suspension: firewall VM fails to reconnect to Net VM after resume
Lorenzo Guerra
I have been using Qubes OS R3.2 for a while (and liking it a lot!) on my laptop. It has worked flawlessly for some time. However,network connection has started to completely stop working properly after suspension during the last couple of weeks
I have tried to reload my network adapter drivers on suspend/resume (even automatically, following instructions on https://www.qubes-os.org/doc/wireless-troubleshooting/), but it has not completely solved the problem.
Since I added the ath10k drivers to /rw/config/suspend-module-blacklist, I have now connectivity in sys-net after suspension, but not in other VMs.
After some trial-and-error, I found that in order to regain access to the internet after resume I need to:
1. disconnect every network from the network manager in sys-net
2. manually reconnect my firewall VM to sys-net by typing "qvm-prefs -s sys-firewall netvm sys-net" in a Dom0 terminal
3. reconnect to my wifi in sys-net
It is not an enormous problem, nevertheless it is annoying.
Is someone else experiencing this issue? Does someone know what could be the root cause and how to properly fix it once and for all?
Thank you in advance.
