My wifi range is reducing frequently

my laptop wifi range is reduce 100 % to 80/70% frequently even if i sit near to router is it any problem with os or wifi driver

I don’t know, but you can use lspci -k (look for Network Controller in the output) to find out which wifi card you have and which driver it uses & post it here, maybe someone else has experienced that problem.

It is unlikely to have something to do with Fedora specifically - Fedora uses the default kernel drivers unchanged.

@astronaut you could check your router and change the channels it uses.
