Hi @MattinNC,

Sorry, no.  The EAP225-OD doesn't have that function.  It cannot act as a "client" (aka STA) on someone elses wireless network.

But the CPE series can.  I'd recommend the new CPE710 ideally.

BUT, this will not really re-broadcast the Wifi for use inside of your RV (due to the directional nature of it's antenna).  Also because an RV is a metal box.  You would need to run Ethernet from this (or the CPE210/510) back into your trailer to either a PC, switch, or an indoor AP -- like the EAP225V3. 

But, before you invest, make sure the campground actually has good Wifi/Internet.  Move close to their AP and test with your phone / laptop / etc.

Many of the campgrounds I've stayed at have terrible Wifi -- too many clients, slow/overloaded broadband connection, poor signal.  In almost all cases I have to use cellular/hotspot/Jetpack.

@JSchnee21 Thanks for the reply! I've looked into the CPE devices but was hoping to find one that was dual-band.

Hi @MattinNC,

No worries.  Check out:

https://www.rvmobileinternet.com/

They review all things RV/Mobile Internet releated.  There are a number of RV specific devices to mount on top of (our outside) your trailer for this purpose.  Many contain cellular modems as well.

In a pinch you can also check out small travel routers like these from GL-iNet.  They're not water/weather proof but you can put then in a bag, tupperware, under an awning, etc.
