I need some assistance in setting up a wireless network at my office. Here is a little background: Our office is rectangular in shape. The dimensions are 200'x75'. The plan is to install 6 WRT54Gv4's in this building so that we have adequate (and I think that is an understatement) signal strength throughout the building. One router will be installed in each corner of the building. The last two will be centrally located on opposite sides of the building. We have a T1 and Cisco router providing connectivity, so the WRT54G's will be used mainly as an access point. They will all be installed above the drop-down ceiling and are currently running Tofu 6.2 (to be upgraded later today to Tofu 12). Now for my questions: Considering that 6 routers will be present... which are the best channels to use? Should we use the same channel, alternate 1, 6, 11 etc etc? One side of the building faces several hotels and as a result is visible to a lot of wifi traffic (mainly on chan 6). Currently, the the tx power is set to 56mw. However, since the signal coverage is so good, I have been contemplating turning tx power back down to default. The plan is also to use the same SSID and WPA key on each router so that wireless users may roam the building. Is this a good practice to follow? Can anyone provide any details on how to better configure or tweak the equipment for the best network coverage possible? Thanks in advance for any help that you can provide.
