	Looks like a netmask issue between the hub and switch.
	converting to binary, we get is (in octal) 377.377.370.000 or
	11111111.11111111.11111000.00000000 (binary)

	Your PC address is (octal) 300.250.5.244 or
	network part            host part
	Your broadcast should then be
	network part            host part

	or 300.250.007.377 octal, or, which
	is what you said.  Therefor both machines are on net
	192.168.7, as intended... and clearly work (;-))

	Despite passing broadcasts, something may still be wrong
	with the switch.  Did you get arp replies???
	Try setting the switch to think you're 
	using a class B subnet mask, and see if things 
	work that way.

	Also look at the switch documentation for ``helper'', ``vlan''
	or ``broadcast'' keywords, in hopes of finding a documented
	bug pretending to be a feature (:-))
