It seems the ping session is the way to go, but considering that the lock up
occurs around after a day and a half maybe a 'every minute' ping is excessive?
Probally every 1 to 2 hours would be better. My SVEC has actually been
behaving itself of late, although I leave it running on the HUB with no
computers running for ages, it still picks itself up when I fire up a computer
on the HUB side of the LAN. I think that the broadcast packets from the
booting up machine wakes it up again. However I would say that a booting PC on
the RF side would not wake it up????
Does upgrading the SVEC with dwl900ap+ firmware (I have read it works???) stop
this 'sleeping'?
