Internet Access At Chiangrai (maesai)

[ahyong]

hi, i travel to maesai very often and have a house there, but i got problem applying for internet access to my house, i had tried TNT & CATS but they told me my house is too far away from the main road to fixed the internet to my house. So i brought a usb sim adpater costs 2300baht to tried using the mobile internet edge by 12call. The speed is really to slow for my work, i wonder is there any other solution? CATS offer me the 3G CDMA mobile usb but i am not sure is the speed fast enough for me, the set costs 7000bahts plus, i need a good review on it before i buy the set. Anybody have solution for me? Thanks
