Nexus 4 poor wifi signal

Hi,
I’m using /e/ lineage on my old Nexus 4 phone for one year and I’m satisfied except that I have a poor sensitivity to wifi signal since this change of OS, ie with the original OS, in same locations and conditions the wifi signal was better.
Any idea ?

Android version : 7.1.2
guava(7)
baseband M9615A-CEFWMAZM-2.0.1701.07
build e_mako-userdebug 7.1.2 NJH47F 20201001 dev-keys

Thanks in advance for your help !
