Hotel internet access can be a problem for wireless-enabled mobile devices. For example, they may pick up only quite strong networks. Or there are some networks that need authentication tokens that are too large for some devices (such as my iPod Touch) to handle.This and this reminded me that many laptops can create an ad-hoc WiFi network, if its internet connection can be provided by some others means. I tried the directions on the second, and it worked just fine. The first contains further ideas if the second method doesn't entirely work.
