Last year when I was in Chiang Mai, I stayed at PJ's place. I brung my brand new laptop with me and plugged into their wired internet system and it didn't work. They worked with me and it just seemed that my PC did not want to work with their system. I just looked at their website and noticed that they now have WIRELESS INTERNET!!! YEAH!!
I am looking forward to staying there and enjoying internet in my room there!
