2014/03/22 (S) WiFi Ants

No, not WiFi Antennas; WiFi and ants, which I will get to later.

Saturday morning the refrigerator temperature was 40 degrees F.  I moved the remote wireless thermometer to the freezer compartment and left it until it settled in around 5 degrees F.  The refrigeration system, including the controls, appeared to be working.  Linda retrieved most of our frozen food and a few fresh things.  We partially restocked the fridge and I set the thermostat a bit lower.  Linda made a tofu scramble to use up some of the fresh ingredients, in case the problem returned.  Yum.

I checked my e-mail and found several dozen post replies and a few messages from RVillage.  We both played with RVillage for a while and I reported another bug.  I also had a message from the WiFi Ranger technical support team indicating that they had successfully uploaded a patch to our WFR MobileTi and switched it to a PRO feature set.  They wanted me to try logging in to the resort WiFi system and let them know if it worked.  I followed their instructions, and it did!  Finally, success!!!  I got back on their support forum to let them know and thanked them for their persistence in identifying and correcting the problem.

As best I understand it, the problem was not a bug in their firmware but rather a design assumption they made that an RV park WiFi system would never be a class 2 network.  Based on that assumption they were doing using IP addresses to connect to other WFR devices (WFR Go) in a way that conflicted with the class 2 network operating in our RV resort. WiFi Ranger thinks the chance of us running into this again is very small (unless we come back here, in which case it’s 100%).  This may, in fact, be the only RV park where we will ever encounter this.

I do not understand all of the details, but essentially a class 2 network has 2^16 (65,536) available IP addresses. That’s a LOT of IP addresses and made me wonder if the resort WiFi system is actually part of a much larger network, perhaps for the city of Williston or even for all of Levy County.  The “explanation” the network technician gave me some weeks ago was that our WiFi Ranger, being a repeater/router, was simply “not a supported device” as a matter of park policy and he was unable (unwilling) to give me any assistance with it even though he admitted knowing what it was and having  set them up before.  He could have just told me they were running a class 2 network and that it might have something to do with my problem, but he withheld that information.

The “logic” behind his explanation of the park policy was that we could “hide” data-intensive devices behind our system, such as streaming-video, gaming consoles, or even a web-server.  That was nonsense, of course.  If the concern was data-transfer, the network could simply monitor and control that at an IP address level.  When I indicated that one of the reasons for our router was to put our devices (and data transfers) behind an encrypted hardware firewall, he told me the WiFi system connection to the Internet was encrypted, as if that was somehow equivalent.  It’s not.  The connection between the resort WiFi system and the WiFi client devices is NOT encrypted, and thus open and viewable to someone intent on doing so.  Unless people are using secure applications, such as most banking software, their WiFi connection is vulnerable.  This is true of any system that does not require you to enter a WPA or other “key,” including the free WiFi at places like Panera Bread.

We have had good Verizon 4G/LTE service here, so getting online has not been a problem, but if that had not been the case we would have been in a really bad situation.  I was anxious to get this resolved while we were still here so they could test possible solutions on a network known to have this problem.

With computer tasks taken care of, we turned our attention to fixing the roof leak.  As we were setting up the Little Giant folding step/extension ladder we noticed ants traveling up and down the cable TV wire.  Yikes!  The cable runs into the bus through a small window by the driver’s seat.  We had used Frog Tape to seal up the opening against the weather, but it was not ant proof.  We checked inside but did not see any ants where the cable came in.  Closer inspection outside revealed them moving up and down along a body seam and horizontally along the floor line just above the bay doors on the driver side of the coach.  We quickly disconnected the TV cable (we don’t use it anyway because the analog signal in the park is not very good) and closed the little window.  Dealing with the ants, however, would have to wait.

Linda packed all of the tools and supplies I needed for the roof repair into a bag that I carried up with me.  The repair was simple enough; use the small caulk gun to apply Dicor self-leveling lap sealant around and up onto all four sides of the Fan-Tastic vent fan base.  This Dicor product is universally used in the RV industry for just this purpose.  It is not “runny” like water but it does flow, especially when warm, just enough to do what its name suggests, flowing into cracks, crevices, and small holes as it smooths out.  It eventually sets up and forms a skin, but remain pliable.  Rain is forecast starting late Sunday and running through the coming week, so we will find out then if I have fixed the problem.  The real problem, of course, is that the fan base is probably not installed properly.  The correct fix would be to remove it and reinstall it, but that was not going to happen sitting here in the RV resort.

Now for the Ants!  These were, thankfully, small black ants and not fire ants, which are a widespread and serious problem here in Florida.  We hooked up a spray nozzle and tried to flush as many of them away as we could.  It’s not that we wanted to harm even these tiny creatures, but we are not willing to share our home on wheels with them.  They are tenacious, and hung on tight or hunkered down in the nearest available crack.  Linda walked to the Grocery Depot and bought a can of ant spray that I applied to the concrete pad around the bus tires as best I could and on/around the electrical and water shorelines and the waste water drain hose.  Later I went to ACE Hardware, bought a couple of boxes of Borax, and used them to establish a defensive perimeter around the coach.  This is a treatment for ants that we have come across in numerous different forums.  The coming rains will wash it away so it will have to be reapplied.

We had a light/early dinner of hummus and pita chips, went for a walk, and then eventually headed to the fire pit with our customary glasses of wine.  John played the guitar and sang for hours, often joined by the group that had gathered.  We were they again until quiet time at 10 PM, at which time John stopped playing and we turned off the lights.  We still had a small fire and I continued to coax flames out of it for a while longer.  Kevin builds the initial fire and lights it, and John was the backup fire tender, but since he is usually playing his guitar I have assumed responsibility for tending the fire.
