My new battery made my wifi disconnect and reconnect constantly.

I installed my ifixit se 2020 battery and now my wifi connects and disconnects non stop. I ordered both wifi antennas and module and replaced them. Problem still present, so I know it’s not the hardware. My iPhone 11 connects to my 2 and 5G wifi just fine so I know it’s not my modem or router. I’ve hard reset the phone several times and reset all network settings with no luck. I’ve replaced iPhone battery’s several times and never had this problem. Any insight would be greatly appreciated, thanks for your time and help!.
