Wireless (Edimax EW-7128g / ral) to work on FreeBSD 7.0

[David Gurvich]

I'm not sure of your settings, but increasing tx power is only good for
transmitting and will increase noise, hurting reception.  Your S:N
numbers look quite poor, I rarely get any handshake when signal is that
bad. I'm surprised you managed to get a dhcp offer.

Have you tried this computer in the same location as the windows
machines?  How far from the router are you compared to those?
