I mostly just use LAN when I need to download a lot of stuff at home,
because WIFI is much slower even at 54 Mb/s, especially since my home
network is 1 Gbps. So I could just turn WIFI off in those cases, that
would be an acceptable situation.
However, I want to understand all of this as fully as possible.
So, yes, I would appreciate your profiles - but please take your time
digging them out :)
