before qubes os I had ubuntu 17.04 and I had wifi problems until I installed the driver "rtlwifi_new" on github (https://github.com/lwfinger/rtlwifi_new). After the installation it worked.
With fedora 24 I didn`t have problems with the internet connection but with the netvm, which runs now at fedora 25, I have the same problems like I had on ubuntu. So I decided to download the "rtlwifi_new" at the fedora template 25. Than I copied to the netvm.
I don`t know to install that driver and I need your help!
Thanks!
