That is a surprise.  It may mean an abort happened.  But if an abort
happened, then you should not get message "No multicast NAND server".

Let us debug further together.

Test 1: check that you typed in the command exactly as shown:

	ok open-wlan 6 multinand-traffic? . close-wlan

The . (dot, period) is important.  It prints the result.

If dot was typed, proceed to tests below, as these tests are for
finding if an abort happened:

Test 2:

	ok open-wlan close-wlan ." done"

Tell me the output?  Will be either ok or done ok.

Test 3:

	ok open-wlan ." opened"
	ok 6 multinand-traffic? . ." done"

Tell me the output?

Test 4:

	ok open-wlan 6 multinand-traffic? . close-wlan
	ok ftrace

Tell me the output?

Your -75 feels like low signal for me.  Try another XO?

I'm not yet convinced you have an antenna problem or a software
problem.  Something wrong is happening, but I don't know what it is

Do you have another NANDblaster nearby, for different XO model?

For maintenance: check to see if the antenna cable is twisted.
