I'm at my wits end here and could use some insight and help. I have a cable modem - hitron cgnm-2250-sdl acquired through suddenlink. I'm trying to change my router from wpa2-psk to WEP security type for the purpose of being able to play my 3ds games on the Internet but it won't let me change - or even click the security type when I log into my router. I've tried a factory reset to see if that might fix an odd setting that was causing this but to no avail. I've confirmed without a reasonable doubt that I am using the original user and password when logging in but it still gives me no control over any of my settings! Insights? Possible causes? I just get a red circle with a diagnosis line - clearly stating I'm not allowed to. Why is this?
