I have had 2 PCs directly connect to our Arris cable/telephone router for many years. I have purchased a new laptop, it "sees" our wireless network as available, but asks for a network Security Key. How do I find this? Thank you!

To find and/or change your network security key, also known as your WiFi network password, you can login to your router's admin tool to do this. The router login information varies by Comcast-supported device, and you can find out the details in this article: Comcast-Supported Routers, Gateways and Adapters.

 

For our latest Wireless Gateway models, you can visit this article to learn how to find and/or change your WiFi password: Find and Change Your Wireless Gateway Network Name (SSID) and Password (Network Key).

What router, exactly? Whoever setup the wireless router assigned a password to your wireless network, what is it?  If you don't know, get it from whoever setup the wireless network.  If you can't, then log into the router and change it.  If you can't log into the router, then reset it to factory defaults and use the default admin password to log in and reconfigure from scratch.

 

I can't be more specific until you say exactly what you have and how things are connected.

I am tryiing to connect my laptop through my SMC router hooked to my desktop. It asks for a secuirty key, which i have not been provided. My router S/N is H210480E5EC5. I would greatly appreciate the security key to do this. Why it was not given to me when Comcast hooked my router up I do not understand.

There shoud be a sticker on the gateway with the relevent information.  Otherwise, simply log into the gateway http://10.0.0.1 and change the wireless password to whatever you want.  The default userid is "admin" and the default password is "password".  If they have been changed, then either reset the device to factory defaults (press and hold the Reset button for more than 15 seconds) or call the gateway support folks at 800-363-2416 and have them take care of for you.
