And such would be a feature of your router or possibly your ISP. I don't see Comcast offering such so let's find a way to get such logs.
And before you ask, that is one of the simplest setups I've seen to date.
Be careful what you ask for!
I am looking for a way to monitor my home Internet activity. Here's my family's situation: we have 2 iPads, 2 iPhones, a laptop, and an Xbox all connected to the Internet through our Motorola (Surfboard) SBG-901 Wireless Cable Modem to Comcast high speed Internet.
Is there any feature on my modem that can record the overall Internet usage (listing the website history accessed) for all devices collectively?
If not, does anyone have recommendations on how I can achieve what I'm looking for?
Your help is appreciated!
