Arris makes good stuff. But that is just the cable modem. It will NOT provide any router protection for your home network. Your network topology should look like this:
ISP -> your cable modem -> your router -> everything else
Honestly, if you don’t have need for many ethernet connections, just get a wifi router with good reviews and the arris cable modem. Make sure the cable modem you pick up has the right DOCSIS version for the speed you are getting or plan to upgrade to. Your ISP will be able to tell you what version they are on.
I enjoy listening to morning edition - usually through the app. I also contribute to NPR monthly. They have to stop the on air fundraising campaigns. It really drives listeners away. At least give those that already contribute an alternative feed.
