Ok here's my problem:
I travel a lot, and sometimes my MacBook Air has issues connecting to some hotel wifi's, while my Android phone connects fine. Also, I have a Lenovo Android tablet that sometimes has trouble connecting to certain hotel networks (not necessarily the same networks that my MacBook Air has problems with!). The only device that never fails to connect properly (knock on wood) is my Android phone (Samsung Galaxy S5).
I'm getting fed up with having to use my tablet when I want to use my laptop, use my laptop when I want to use my tablet, or resort to my phone when all else fails.
I know I could get an external wifi dongle for my laptop, but then that would probably (?) not work with my tablet (even through OTG), right?
So what I'm wondering is this: Is there some device out there that can connect to a WiFi network, and at the same time act as a WiFi hotspot? Using such a device could potentially let me connect to one of these problematic WiFi's (supposing it too does not have the same problems connecting as my laptop and tablet have!), and at the same time let my laptop and tablet connect to it's hotspot. I've tried looking for something like this, but not sure what it would be called?
