I have just in my room pretty bad internet reception on the phone. My laptop has LAN and has the ability to open a hotspot for other devices. Since then, my phone has 1A Internet reception, my question: are there any disadvantages?
Yes, the power consumption of the laptop. Because to go online with the smartphone, you have to start the laptop. This is totally awkward.
Alternative would be: A wireless access point (or a wireless repeater set up as an access point, there are already from 10 euro) in the LAN box to plug.
Finished! You then have great Wi-Fi reception in the room and the laptop does not need a LAN cable anymore, can connect as well with this wireless access point in your room. No clutter on the laptop. Without laptop turn on super Wi-Fi for your smartphone.
