With 'best' I mean: high speed, and not crowded with noisy kids playing games all the time.

I bring my own laptop.

Why not got to a place that has free wifi or do you need to use the printer or something else as well?

Many restaurants and bars have free WiFi such as Wrong Way Cafe. Also you can usually get online in the lobby of most hotels—just go to the front desk and ask for the log-in information (though sometimes not free). Then there are the food courts in Big C, Tesco-Lotus or the City Mall where you can buy minutes at the near-by See Ed book store and get online with their Spider WiFi HotSpots...always plenty of room and good connection speed, but not necessarily quiet.

Cheers

Plenty of free networks around Sunee.
