Which device to choose in order to be with the Internet in areas of weak signal (on vacation)?

Question

WiFi

This is not the first time I have encountered a problem when traveling to places of rest both in Russia and abroad, that there is wifi in places of rest, at the reception and it even catches on the balcony of the room, but it doesn’t reach the room itself, or it works intermittently , so if you want the Internet, you have to hang from the balcony)
Hence the question: is it possible to pick up a device that you can take with you (preferably compact in size so that you can take it with you on a plane with you in a suitcase), which would cling to the guest network and broadcast would a stronger signal to tablets / phones in the nearest area?

Answer 1

I think a wifi repeater is suitable for you
