This is a lame duck, low effort post. And if you already know it it’s obvious. However this question seem to be asked a lot on the intertubes. I hope it will help someone else, as there is no good readily available answer out there.
Problem: I wanted to have SNMP on my Comcast/Xfinity router so I can monitor current bandwidth usage.
- Possible to enable on vanilla router? – Nope
- Do 3rd party, Comcast compatible routers do? – Nope
- Can you SSH or hack in to the router to do it? – Nope
- Can you load custom / hacked firmware to do it? – Nope*
Nope or very hard / unsupported.
So is it possible at all? Yes, but with a separate device. Comcast/Xfinity routers have so called “Bridge Mode” which essentially turns them in to a DOCSIS modem without router / firewall / wifi access point.
Solution: Turn on Bridge Mode in your vanilla Comcast router and buy a WRT firmware router / access point. I got Linksys AC3200 for $99 on Amazon. Ssh to the router and run: opkg install snmpd
