C7000v2 I reset my router password but my apple watch can't distinguish between upper and lower case

I'm not sure exactly what you're wanting. 

Are you wanting to change the ssid on the C7000 so its all lower cases? 

Are you wanting help with your apple watch? 

What's your goal here?

 

There's a support site with access to manuals, firmware, install guides, etc.

Type in your model number and from there it'll take you to the above.
Its a great resource to start with.
