Thanks a lot guys. Both of these explanations are excellent.  

I have been messing with routers for years, as we live in places that have 
complicated and multiple structures. I learned a lot from having to daisy-chain 
routers to get my wifi signals to cover a variety of places.  We left New York 
City for Key West in 2010. In NYC we had Time Warner cable internet, pretty 
fast when the whole neighborhood wasn't home using it.  The beauty of that was 
the modem was separate from the primary (most upstream) router.  I could buy 
whatever router I wanted, and then run downstream routers, (some with little 
500mw rf amps and bigger antennas) off of that one.  

I had no problem getting good results throughout our 5 story Manhattan 
"brownstone" by stringing wires up and down the outside of the building to 
downstream routers on each floor.  I used, with good result, Linksys, D-Link 
and Netgear.  

BTW, not totally OT, it would be great to hear what people have to say about 
reliability and durability of all three ( or other ) brands. They are equally 
easy to set up and use, all with nice webpage interfaces,

The AT&T DSL and the more advanced AT&T U-VERSE DSL use routers (2-Wire in the 
first case, Motorola in the 2nd) that DO NOT separate the modem from the 
router.  I despair of trying to explain the problems this creates to an ATT 
customer service rep in St. Paul or Bangladesh.  There are a gazillion posts 
on-line from people having problems with the Motorola NVG510.  The only time I 
seriously messed with the 2-wire, before I upgraded to U-Verse service, I lost 
internet for the whole family for several days.  I am tiptoeing around now to 
avoid a re-run.

Several of the posts said they had solved the NVG510 problems by using that 
device just as a "bridge" and then putting a regular (maybe Linksys) router 
behind that to handle all the router functions.  I assume "bridge" means 
essentially a modem only. I'd love to know more about that, but I am terrified 
to try much more messing with it.

I am familiar with port-forwarding, as you have to port-forward to set up the 
radio-end RemoteRig for the remotely controlled K3. I also have a very robust 
remotely controlled Web7 power switch that lets me turn things on and off up at 
the "big station" in MD that I am remotely controlling.  That also requires 
port-forwarding. 

I also leave a PC running in MD on an uninterruptible power supply, and I use 
that to move my rotor and control the KAT500 if needs be. I have put that on a 
static ip on the LAN.  

The external static ip that I need here in Key West, for which I pay $5 per 
month extra, is needed for a system of remotely viewable surveillance cameras. 
Those were installed by our alarm company, and they wanted me to get the static 
ip.  My problems with the K3/0 started after that visit by the ATT technician.

So, unwilling to try the "bridge" approach for fear of really getting screwed 
up, I tried plugging the RemoteRig Control unit into a downstream ( 
daisy-chained) router from the NVG510, and the problem went away.  I am 
throwing no parades until this fix proves to be lasting,

What was so bizarre in all this --- i should be able to take the K3/0 plus 
RemoteRig control box (RRC) to a local Starbucks and get on the air using wifi. 
I should not have to do more than change network addresses in the RRC. Why the 
NVG510 isn't similarly blind to the device attaching to it seems illogical. 
But, nevertheless, once the tech left, having set up 5 static external ip 
addresses, the RRC and K3/0 would turn on the remote K3, I could hear it, tune 
it, change modes, filters, key up, etc., but none of the changes made at the 
radio end were reflected in the front panel of the K3/0. It just sat there 
saying 21.000.00 CW. 

Now, having plugged the RRC in one box downstream, it all works again. Further 
mysteries remain, but I am going to pretend all is well. 

Sorry for this long screed, but I am hoping it will:

A. Help someone else
or
B. Stimulate someone to offer a better fix.

73 to all. Happy Holidays to all.

Brian, W3BW
