@Quirico , I will gladly answer both of your questions:
- If I have two providers and only one PC with one Internet-cable socket how will I practically connect to both?
I think with a second network card you can connect both providers to your computer.
- Will I need a switcher?
You could also do this with a dual or multi-WAN router, then you don’t need two network cards.
- will it work via software or will I have to manually switch connections?
I can’t answer you, because I never did this.
- I could also put my problem this way: Can I access Swisscom via a fast UPC connection?
This question I do not understand exactly. But yes, you can also reach Swisscom services via UPC.
Maybe @millernet still has some tips? 😀
Greetings
Daniele
