Change of Wi-Fi

I recently had to change my wi-fi router because of an issue. I'm still with BT but the wi-fi password has changed as you would expect. I have tried to reconnect my cameras to the new network and even though I'm entering the password correctly, only one camera accepts the password. I have tried my chime pros and remaining 4 camera all without success. Any suggestions as I know I'm entering the password correctly. Thanks Mark
