My old iPod touch won’t connect to my wifi.

I’ve been researching this for a bit and trying to figure it out, but nothing seems to work. I know my wifi network is putting out 2.4ghz and 5ghz, but I’m not sure if that is the problem. I’ve repeatedly tried to connect to my wifi, but apparently, the wifi password is incorrect. I’ve verified numerous times and it is correct. I’ve also reset the network settings and everything else. Any idea what is wrong? Thanks!
