Not Telling
I just tried to pre-amp them with my other Creative Labs 2.1 amp. This boost the volume (though too high) and the subwoofer of this set is on as well which I don't want. (no two subwoofers):-).
We're getting closer.. Anyone can make a recommendation?

If you buy from AIS, DTAC or True, it will be a factory unlocked version; no need to jailbreak.
True. I don't want to jailbreak it to have it unlocked as it already is. I want it to use my user profiles without digging down into settings and flipping 10 toggles just to put my device into a certain mode. Another reason is to have "real" multitasking and not the "multitasking" that Apple offers which hardly is capable of anything decent. Lastly I want to take control of the device that I pay 26K for. Wireless synching, firewalling, all things that a standard device cannot do. Even the current "folders" that Apple offers is a mess to use. All of the small icons make all pages look the same. Better would be to use the jailbroken "categories" approach where you can assign a custom icon to a group of apps.
Looking forward to greenp0ison. Is that the firmware dependent JB? That would be almost impossible for Apple. Also good that the courts in the US ruled that jailbreaking is legal so it would be good that Apple tries to stop it. If it would release a jailbroken model or app for it that costs 3K baht, I'll gladly pay it.
How is the iPhone 4 doing for all of you so far? With the bumper or other cover, is reception better, worse or similar to the 3GS here in Thailand?

The usual headache: bridges, accesspoints, routers.
The magic word: OSI model.
Layer 1
This consists of the physical network - in this case the utp wiring for the LAN part and the radio signals for the WiFi part. There's 4 non-overlapping bands in the 2.4GHz range: if you configure channels 1, 5, 9 and 13 on 4 nearby accesspoints, these will not interfere with eachother.
Layer 2
This layer has nothing to do with TCP/IP yet. It's the layer where MAC addresses play a role. An accesspoint works as a bridge on this layer: it bridges traffic between the wired and non-wired physical networks. To perform this function, it only needs to know which MAC addresses are on both physical networks and it'll keep track of these addresses in a table.
Layer 3
This is where the IP protocol starts. All physical networks that are bridged together at layer-2 are seen as 1 network on layer-3. This means that all devices on this network will have an IP address from the same range, and they will all be able to ping each other.
An accesspoint has an IP address, but that's only for the purpose of configuring/managing the accesspoint. It's IP address does not play any role in it's basic function: bridging between the wired and wireless network.
In the setup of the OP there's a network consisting of 2 accesspoints and a router which connects this network to the internet. The easiest setup is to make this one single layer-3 network:
Use the network 192.168.0.0/24 (/24 means the subnet mask is 255.255.255.0)
Give the router address 192.168.0.1
Give accesspoint1 address 192.168.0.2 and set it to channel 5
Give accesspoint2 address 192.168.0.3 and set it to channel 9
Configure the same SSID on both accesspoints; any device will automatically select the strongest signal.
If you're using a wireless router as an accesspoint: use one of the LAN ports to connect it and leave the WAN port unconnected. Only configure an IP address, subnet mask and default gateway.
Configure only one dhcp service, e.g. on the router that connects to the internet.

Hi Prasert,
1) Thank you a lot for your post. A question regarding layer 1. I have a lot of traffic around me and most of them on channel 1, 6, 11. Currently I have my AP's set up for channel 4 and 8 as they seem to be rather empty. Is that a good choice or should I change it to 5 and 9 anyway even though my signal strength may weaken?
2) Regarding layer 3. I'm no expert on subnets so bear with me :-). I have it currently set up as 192.168.1.1 .. is there any way that I can keep that? I had someone set up a vpn connection to my machine from my web server so I can access my mail remotely. I uses my 192.168.1.61 ip address somehow and I have no idea how it would need be changed. Is there any other solution to this?
3) The last points were clear and are what I think I was doing. I just don't understand why 192.168.3.1 is responding to pings to 192.168.2.1 (before I changed them it was the same 192.168.1.3 responding for 192.168.1.2)
