figures. I say that based on this link I have:

Distance: 29 km, clear LOS
Far End: 14 dBi slotted WG with 30 mW AP
My End: 18 dBi modded Galaxy & Minitar AP.

I am not saying it is top of the class....but can't be down with the
DLinks of the world.

Cheers

Rob

Hi Nick,

The default tx power of the WRT54G is 15dBm (30mW) although it can be
increased to 84mW (19.4dBm) - according to
http://www.seattlewireless.net/index.cgi/LinksysWrt54g
However increasing the power to this level has a history of frying the
radio after a couple of months.  Apparently it can be increased to 50 or
60mW safely (60mW = 18dBm = Minitar power output) The receive
sensitivity is unconfirmed but listed on the above page as -80dB for
11mbps, which is fairly standard for a 30mW radio.  I would assume that
boosting the output power does *not* also increase the receive
sensitivity. Note that I've not seen the receive sensitivity of the
Minitar AP published anywhere, and I suspect that it is rather deaf.

Here's a link to a homebrew outdoor enclosure for the WRT54G

and ensuing discussion

Dimensions of the plastic case are on the Seattle Wireless site above
(in inches).  At a rough guess I'd say a WRT54G seems to be about as big
as two Minitars placed back to back (with their Ethernet ports facing
each other).
