Airport 3.4 Problems
Apple’s new Airport Extreme 3.4 update has very definite problems with loss of signal strength and dropping connections. If you haven’t installed it, don’t do it. If you’ve already installed it, xlr8yourmac has an article that tells how to revert to 3.3.1.
In my own experience, iStumbler reported a signal strength of 60 when my powerbook is in the same room with my access point (a Netgear WGR614) and 37 on the opposite side of my home when running Airport 3.4. After reverting to 3.3.1, the signal strength is 70 in the same room and 48 on the opposite side of my home (about 100-110 ft). I also found that 3.4 often failed to obtain an IP address via DHCP.
