Wifi not letting my phone connect

So i got a iphone 13 and whenever i try connecting to my wifi it just refuses it says that it cant connect and its always the same wether i use a correct or incorrect password idek if its checking atp and its been doing this for like 2 weeks it can connect to other networks fine but my home one idk i do have a wifi extension and it does occasionally interfere with the wifi but even when i disconnect it it still wont let me connect what do i do? (I alr tried resetting my phone multiple times)
