I have an Arris SURFboard SB6121 cable modem (2014) and a Linksys Wireless-G 2.4 GHz router - WRT54G V3 (2005). Both were last used until a few years ago when I canceled my cable service and changed to Windstream.
These are older technology but perfectly capable of providing service using Spectrum cable if you want to use e-mail and to surf the Internet. These may or may not have the capacity for video streaming. I also have the modem manual and the router's installation disk.
These are available without charge. If no one wants them, I will either donate them to the Women's club, or will end up recycling them.
