No internet. Network icon spins but does not connect (ethernet)

nope, just my router Cisco with wires Cat7 going through the appartment to my 3 laptops, and this tablet on low level wifi

Me neither as I’m using the exact same laptop, exact same network, just much much slower (and barely capable) on Qubes. I can’t open more than 3 tab on just one FF session, while my windoes has 3 different browsers open with I would say 30 something tabs (the idea of separation by using different browser for different tasks)
