Here is my Wifi Ranger Mobile install on my 2010 FC 23FB
I used this 21mm hole saw from Amazon to cut the hole in my trailer available here (see link below) and chamfered the holes to remove any burrs that would compromise the seal.
Amazon.com: 21mm drill bit
I used the IP67 rated bulkhead connectors shown below and can be sourced at
CAT5 RJ45 Waterproof Connector IP67 weatherproof outdoor ethernet
I sealed around the hole using the Airstream approved sealant SIKAFLEX in white and I used the 3M barrier tape around the connector to add layer of protection at the break between the bulkhead and the upper shell.
Along with adhesive heat shrink stepped down to add a seal to the cable a little further up and provide a little strain relief. I think this is a great solution instead of the 5/8 hole and cork method presented with the WiFi Ranger Kit. Probably not cost effective but cheaper than a leak!
I cut and crimped the RJ5 connectors and snaked the wire down to a suitable opening in my cabinet and grometted the wire to prevent chafing and into my "electronics shelf" where i attached the POE to the wall using command strips.
Booted up the ranger and all worked great! I see about 40 Wi-Fi stations in my area. My phone and computers see three. I think this is a great solution for those of us that travel for work in our RV's and I wish I had this unit this summer when I was doing the bulk of my travel.
I head south next month and cannot wait to see how well it works. I took it over to Seattle and was camping on a lakeside and could see and connect to a marina across the lake. I am sold on the WiFi Ranger Mobile!!
