For the Hotel issue, put the Router in AP mode and you'll still get the landing page....
and will he actually be able to do that with out having a wired connection to his Router? going from AP to Router and Router to AP has required more than one user to do a "reset" to regain access to their router. I'd also switch off any auto firmware update. Does the Surface RT os even support a "static" IP address? on my surface pro 2 there are not a lot of settings for the AVSTAR 350N Wi-Fi adapter. one really needs to dig to find out how to enable 40 Mhz channels and beam forming.
