When I start my laptop, after I login to the Plasma session, wifi takes a long time to connect to the saved network. I didn't measure exactly, but it seems to be around 15 seconds. Once it is connected, if I disconnect, and manually reconnect, it is almost instantaneous.
Before I moved to Plasma I had Budgie, and it did not have this issue, wifi was connecting fast at startup. I have another laptop with Budgie currently, configured with the same saved wifi network, and it connects almost instantly at login.
The only reason this is bothering is because I have to wait these 15 seconds before launching Firefox. If I launch it before wifi is connected, it will not find any webpage even once the connection is established.
I installed Solus using the Plasma iso. My wireless card is the Intel 7265. Let me know if I can do anything specific to provide debug information.
