(CNN) -- Business travelers have grown accustomed to hitting snags when they try to set up their laptop computers at many hotels, but improvements are on the horizon. Many hotels are installing high-speed Internet connections.

At the Hyatt San Jose in California, guests can log in through an I-port hook-up.

"Most of our guests are used to high speed either for ISDN or through T1 lines in their office. They don't want to be stalled out on a 28-8 modem, sitting there waiting for their office to come online," said Jeffrey Burg, a hotel spokesman.

Other hotel groups, such as the Hilton, are testing high-speed Internet connections.

The hotels are responding to demand. In a survey by American Express, two-thirds of business travelers reported that they travel with laptops.

"Road warriors used the computers much more frequently than in the past," said Richard Siemborski of American Express. "They were very high-productivity tools."

Some hotel rooms already are set up with the I-port connection, which comes with free Internet time. Other "business plan" hotel rooms come with PCs set up for Internet access, and guests pay to surf the Web by the day or the minute.

However, there remains another snag: Corporate firewalls in place for online security may block access from your hotel.

"Most traveling professionals really need to access their proprietary corporate e-mail and also obtain data and information from their internal corporate networks, and right now, in most cases, that's almost impossible to do from public access Internet," said Dexter Wood, a manager for PricewaterhouseCoopers.
