rsu wireless driver crapshoot

My Internet connection on this computer is very iffy at best, not running as I type this. 

Motherboard is MSI Z77 MPOWER. 

Ethernet is Realtek (re): good with NetBSD, Linux and Haiku, (Free,Open and DragonFly)BSD bug out.

Only Internet connection for FreeBSD is Hiro H50191 USB-stick wireless adapter, chipset RTL8191SU, device rsu.

Sometimes it connects.  Running ifconfig (by itself), I get, whether connection is working ot not,

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384

Looks good, but running host on a valid domain, such as
host bluegrass.net
gives me

;; connection timed out; no servers could be reached

Even when the connection is successful, it can quit any time without warning, and only way I can tell is by trying to reach an internet domain.

I feel like Cinderella, but she had the advantage of knowing that her coach would turn back to a pumpkin at exactly midnight.

Internet connectivity problems are the same whether I run FreeBSD-current or 10.0-STABLE.  FreeBSD < 10.0 offers no internet connectivity at all.

Now I have to save this message, shutdown and boot into NetBSD to send it.

I also use NetBSD to update src, ports and doc trees with subversion.
