ok so since it's an ipad... it should have a usb/thunderbolt port on the bottom normally used for charging... however you can actually get an ethernet dongle for them!

then you can hardware the ipads if you wanted to.



this one here has both a usb port and an ethernet port, you can use the remaining port to keep them on power too.

otherwise you're best bet is probably to setup a second router, one with at least 2 antennai, probably more, but ideally one that can handle a lot of traffic, another option is a wireless access point, you can have a dedicated one just for the ipads and such in the office, connect via eithernet, setup and bam!
