WiFi oder Wireless (wie schon geschrieben). Aber am besten nach "Internet" fragen, weil aus Sicherheitsgründen einige Hotels damit begonnen haben, Internet nur noch über Netzwerkkabel anzubieten. So zum Beispiel die Golden Buff Loge in Boulder, Colorado:
Our hotel is hardwired for free internet access in every room. You may have heard, lately, about the peril information on your computer may be in when you are logged onto a wireless connection; basically anyone using the same antennae may have access to your hard drive. While no internet connection is completely safe and, we can in no way guarantee the safety of your computer, we have taken strides to make our link more secure. We use the highest quality Cisco managed firewalls and switches that are port addressed to each room to help alleviate some potential risks. At up to three megabytes of bandwidth available and a patch cable supplied by us, you are certain to enjoy this aspect of your stay.
Gruss,
