motel

The wifi here is dreadful. I'll be here for a while. Could I purchase a co-axial modem (or router, I think I need a modem though right?) and screw the co-axial cord from my cable TV into the modem to get a hard connection or am I stuck with this crappy wifi? Do you think they'd let me get DSL...

I get no splash page to put login details in for motel 6. I've already checked several answers on google and the most common one is to force the splash page to open by copy/pasting an ipv4 address into my browser or something, but that section is literally just gibberish- it looks totally busted...
