I have changed a setting in the router here. From WPA-WPA2 mixed to WPA2-PSK/AES. Based on a suggestion found on the web to improve the wifi situation in general. This was not needed when using Windows but it certainly has made my wifi on Solus a lot more stable so far. I think the issue is solved for me. I will monitor a day or so and add the Solved tag afterwards.
PS. I will open a new Topic on the Audio performance, this is breaking up with a lot of added high frequency noise.
