question quality signal

Hi All , have netgear 3500v1 and understand why quality signal poor after power shut down my router ?

explain : power on my router and go factory default, after charge backup and reboot.

my signal quality is 80% 

if reboot not change 80%

if power down electrical  my signal is 40 %

my question is why signal change after power shut down my router ?

and if back to factory defalut my signal are good ?

just rebooting not change my signal only if power shut down.
