I am using this Canary Wireless Internet Access sniffer or finder, it works pretty good. I found one hotel off Khao San Road where I can pay to have WIFI in my room, it is the Lampu House, only good on the first floor, maybe...? For 30 Baht per hour and many codes and such, probably easier to go the Internet cafe.
I am in the Mango Lagoon or something like that, directly behind the Wat or Buddhist Temple on the one end of Khao San Road.
There is WIFI in my room, I go out sniffing around and when I came back I saw this 2 bar open signal outside my room. I am in an ALL concrete room, this is a problem, I opened the window and the signal works. Not strong, however OK, I am not sure, this is a test, I suspect they turn it off at night.
Last night I turned on my computer, however nothing showed up, who knows, this is not a stable enterprise hopping on free signals.
I purchased an Access Point Thumb-drive thingy in the USA that allows me to put a WIFI collector or receiver on the end of a USB cable. I think I can connect this to my computer and put the cable out the window, it should bring the signal inside the concrete room.
90 percent of the time the problem is concrete, most homes and hotels are built out of concrete on the planet.
I need to get the receiver or antenna outside the room, I am going to buy a longer or about 10 Yard or 10 Meter long USB cable tomorrow at Panthip Plaza, one of the best computer malls in the world about a 120 Baht Taxi ride from Khao San Road.
What is interesting about the sniffer is the names of the signals. I found or matched the name of the signal with the hotel and was able to find it, this is a help when I can read the name of the signal.
