Been there done that..... Welcome to the world of
wisp.
You'll LIKELY find out this was NOT a radio problem in the
end. It's easy to get focused onto the wrong things.
You don't have to have a nema box for this. It's only a
temp thing. Strap things up on the tower if there's no fence, just out of
reach.
Pull the ups unit offline, just use the surge protector.
Try a different switch etc.
What happens when one of those units (you still have the first
dead one right?) is reset and run in the office? Check the power injectors
too. I just had one that was fubar. Powered up the radio but no
ethernet connection. Changed the power shot and off it went!
Here's how strange things can get sometimes. I just got
a new test monitor for the shop. Had TWO computers that would not work
with it. Thought the first one was the video card in the puter (my laptop
worked just fine with it). The second was one of my gal's new Dell boxes,
she took it back home and it was fine. Changed the power strip, ups unit
etc. Ended up being the keyboard!!!! Go figure.
You may want to order a couple of tt cpe units in ap
mode or something just to try. Put one up in place of one of these
other radios. You'll be about 4dB short of what you are now but that may
not be the end of the world.
Oh yea, I've had a real problem of late with electrical
systems that have bad grounds. The dirt is soooooo dry here we're not
getting good grounding. I've seen 30 volts between antenna connectors and
the pigtail when they are unplugged. That'll cause all of the grounding to
go THROUGH the radios and I've had that blow at least one if not two usb
radios.

Marlon,
I have no weather proof area to put anything in on the
ground - my NEMA box is on top of the tower. And the city would not
allow me to run extension cords down the water tower, everything we do has to
be up to code. BTW, I just got home and checked NMS and now I have two
down, number 4 and number 8. I doubt seriously I can find someone to
climb tonight, so they will be down until probably tomorrow night. I
will be very lucky if I don't lose what few customers I have. This is
beginning to look like a losing battle.

Get a couple of 100' high grade extension cords. Put
your ups unit on the ground and when you need to reboot them just pull the
plug for 10 seconds.
Not a good fix but better that what you have till we
figure out what to do about the ap's....

Marlon,
My AC runs up the water tower from a breaker at the base
of the tower. There is an AC outlet in my NEMA box with the UPS
plugged into it, a power strip into that, with all the power supplies and
the D-Link switch plugged into that. All the cat-5 is outdoor rated,
shielded and gel filled, all cables tested with a cable tester after being
built up on the tower. As for lightning arrestors, we haven't had
any sign of lightning or a drop of rain in months - this is north Texas
where rain doesn't exist from June until October. I don't see how I
would run a power cord down the tower, it just doesn't seem
possible. We can try moving the cat-5 cables around to different
ports on the switch to see if it is one port on the switch that is
failing, but since we have had two different units fail now with the same
exact problem and they are on different ports, I don't think that would
tell us much.
Any more ideas - I am always willing to listen and try
different things,
Gloria

First off, run a power cord to the bottom of the tower
for a bit so you can just unplug it to reset everything
;-).
If multiple units are seeing failed eithernet ports
you might need to look at your switch. Also, might want to make
sure you have good lighting arrestors on the cat 5 ports.
In almost 4 years of this wisp stuff I've only lost a
couple of ethernet ports and both of those were at the same place and on
the same linksys cable router.
Until this fall. We lost two sb radios with dead
ethernet ports durning a storm. One ap and one client. At
one location the homeowner also lost the ethernet port in the dell
computer. At another location all radios are fine but the customer
lost a nic in a dell computer.
I'm thinking that there may be some crappy ethernet
ports on the market?

Marlon,
I don't have any spares here. The only extras
I have are the one we took down night before last that we thought was
bad, and an indoor that was sent to me instead of an
outdoor.
We replaced the POE with a known good one on
Wednesday night, we replaced the radio itself Thursday night, and
replaced the power supply last night. So far it is up, but it
usually takes about 24 hours for it to go down.
Now a different one is down - same problem - dead
Ethernet side, can't talk to it. This is the first time this one
has gone down since we put them up three or four weeks
ago.
If you have any more ideas, let me know. I am
willing to try anything at this point, if my techs don't quit because
they are sick and tired of climbing the water tower every night to
either reset something or replace something.
Thanks for your help,
Gloria

You have other ones there right?
First, swap ethernet ports on the switch.
Swap power supplies and then power injectors (I just had a bad power
shot) with a known good working unit.
If none of that works, swap the ap with a known
good working unit. If the problem moves, yep, really bad
luck! If the problem stays with another radio, it's
environmental.
I know when we first got started we were on one
end of a 30 mile ptp wmux link. It would totally shut down my
radio. Similar to what you are seeing.
Call me and let me know what you find or if you'd
like to talk about this a bit more.
*Time to learn those trouble-shooting techniques
;-)*

with APPO problem
Anyone got suggestions as to what is causing one
of my APPOs to go down? We have had to climb the water tower
and reset it three times in the last week. We replaced the
POE on Wednesday and it went down again Thursday. I ordered
a new unit overnighted and replaced the unit last night. It
worked great all day today, but is down again now. The
outdoor rated cat-5 run is only about 20 feet, the cable was
tested with a cable tester before putting it in place, everything
is water proofed (even though we haven't had rain in
months). What else is there? The POE was replaced, the
entire unit was replaced, and we still have the same exact
problem. When it does this, the Ethernet LED is off, the
Power and TXRX LED is on solid, and we have no communication with
it. Did I get so lucky as to get two bad units with the same
exact problem? The only item that has not been replaced is
the power supply - could that be bad? All the other units on
the water tower are working fine since I upgraded the firmware
last Sunday. They are all plugged into the same switch,
which is plugged into a UPS and all of it is in an air conditioned
NEMA box.
smartBridges tech - or anyone -
help!
Thanks!
Gloria
