Can't connect with hotel wifi or hardwire

[hockeysticks]

I am unable to get online via our hotel's wifi or hardwire while on a short vacation.  A yellow triangle with an exclamation mark is on both the wifi icon and the landline icon.  I am unable to open a browser in order to type in my hotel-provided username and password.  My iphone works fine but not my laptop (Acer Aspire Timeline X).  When I troubleshot, it says "Windows can't communicate with the device or resource (primary DNS server) and Problem with wireless adapter or access point - both detected. 

Any suggestions?  Very frustrated...

Thanx
