network throughput with WiFi/LAN

Someone PLEASE help me figure this out?
I am baffled.
I have 2 100% identical IBM servers. Same everything. Purchased at the same
18GB scsi u160 10Krpm drive
One machine runs FreeBSD-5.2 and the other Solaris9x86.
FTP transfers via machine to machine or via LAN client to/from either machine
are around 11.5MB/sec (which I would expect on 100BaseT).
Thats fine. However I did notice the following:
WiFi 802.11b client machine (10' away from the AP and excellent signal)
sees the following transfer rates:
WiFi client to solaris box will sustain and maintain 821K/sec.
WiFi client to FreeBSD-5.2 box will start around 900K/sec and immediately
fall and fall and fall - settling around 620K/sec sustain and maintain.
Since ftp rates to/from servers/clients are at just about the max, I dont
understand what I am seeing here. What does the FreeBSD box not like about
my WiFi ? - the recv/send space is set identical on the solaris and freebsd
Any thoughts? - Since I use WiFi a tremendous amount - solaris seems like
the answer but yet it makes no sense.
Any thing I can try? - everything is full duplex. Verified speeds and settings.
