[MLB-WIRELESS] Nodegdw to GHO update

	not sure, it was using about 27kb/s worth of bandwidth though

Maybe, but I don't give up that easy, after all I am learning as I go. I am
also generating some discussion on wireless issues to the group. I probably
will dis-continue the link, but while it's up there I will tinker a bit
more. My intention here was to link the east to the west. But if I can't get
it to work properly, I will try something else.

I have tried changing the RTS threshold's but didn't seem to make much
difference, also tried MTU sizes.


Seems to me that GHO is in a good position as far as LOS goes, but bad for
RF interference. Also gho is operating on channel 9 which is too close to
0477c8 which is on channel 6, it should have at least 5 (4.4) channels worth
of separation.


Cheers,

Richard.
