Yes, the problem is the wireless link.  802.11g is sufficiently fast to 
display images in Cygwin/X while 802.11b is not.  I use 802.11g at home 
all the time to get an Xdmcp session on my Linux machine and it is 
slower than 100 Mbps Ethernet, but it is fast enough to do what I need 
to do.  Dropping to 802.11b would not be acceptable for me.

Hope that helps,
