Can't connect any TP-Link network after installing a custom ROM on the Redmi 7A and rooting it

I recently flashed a custom ROM and rooted my Redmi 7A, and now each time I try to connect to a network from a TP-Link router, it just says "Check password and try again," even though I insert the correct password. Also, before rooting and flashing a custom ROM, it worked just fine, and I have tried multiple ROMs, and it still doesn't work.
