Difficult to tell. Wireless can run at any association speed between
1Mbits/sec and 54Mbits/sec. Troughput is about half of that. Throw
in MIMO and/or performance enhancements and speeds of up to maybe
300Mbits/sec are theoretically possible. If one wireless connection
is running at 9Mbits/sec (the slowest 802.11g speed), while the other
is at 54Mbit/sec (the fastest 802.11g speed), the slow connection will
hog 6 times as much air time as the faster connection. There will be
some interaction, but because of the speed differences, the 9Mbit/sec
connection will *SEEM* to be 6 times slower. In general, the computah
that is closer to the wireless router will seem faster and more
There's also an issue of bandwidth distribution. With a 1.5Mbit/sec
DSL line, the wi-fi is much faster than the DSL line making the DSL
speed the limiting factor. However, with a 6-12Mbit/sec cable modem
connection, the match is much closer, making marginal wi-fi
connections a bigger factor than network speed.
Wi-fi is also not the best in terms of reliability and consitency. If
the neighbor happens to be using the same RF channel, you'll
experience interference on one of both of your wi-fi connected
computahs. The problem is that it's difficult to determine if it's
something you're doing with your system, or interference from the
neighbors streaming video system. If you want reliability, stay with
the wired connections.

None. You're fine. What you're basically asking is for us to predict
your wi-fi performance. Even if you supplied us with a layout of the
building, and RF sniffer results for the neighborhood, it would be
difficult trying to estimate the performance of your machines.
