Need help with wireless adapters for screen mirroring


Right off the assembly line
Does using Wi-Fi on a 5ghz band help in better screen mirroring than 2.4ghz?
I'm currently using a 2.4ghz Wi-Fi dongle on pc for casting (to fire tv) and I see some lag in cursor movements and screen transitions.
Will upgrading to a 5ghz dongle be worth it?

Maybe it will, might be the bandwidth is getting used up completely or most likely the dongle doesn't support good upload speeds. Mirroring using a 4G dongle isn't usually a good idea.

Check with various resolutions like 480p/720p etc & if lag is still there then it might also be that hardware of dongle is weak. If lag is not there then there is a chance(nut not certainty) that using 5GHz band will improve the situation.
