I'm disappointed as having an extra port is really nice for troubleshooting with a directly connected laptop, bypassing the separate router between the MB8600 and the rest of the network. **Q: Does this use the now-notorious Intel Puma 6 chipset?** A: Model MB8600 and all Motorola products use Broadcom chipsets and do not have the problem associated with the Puma 6 chipset. **Q: I also need wifi, what do you recommend?** A: The MB8600 modem will work with any WiFi router. Given the speed of the MB8600, you should be using at least an AC1900 router and given the other devices in your network, you might be able to take advantage of a wireless speed even faster than AC1900.The Ethernet port on the MB8600 simply plugs into the WiFi router of your choice. The router should be current enough to have a Gigabit WAN port (10/100/1000 Ethernet port), since you will need that for the speeds that the MB8600 can deliver. And for now, 1 Gbps service is the fastest cable service Comcast is providing in the US. When Comcast or other cable Internet service providers begin providing service speeds over 1Gbps, the MB8600 has the bonded Ethernet ports which will allow the MB8600 to deliver speeds above 1 Gbps. We are not aware of a consumer-home/small office router that does Ethernet port bonding today, but they are coming. Ethernet port bonding is available on Enterprise level routers (routers used in large organizations), but we can't recommend that class of product for a consumer at this point. They are more complicated than you need and more expensive. Bonded Ethernet ports for consumers will appear by the time Comcast is ready to begin delivering speeds above 1Gbps and the MB8600 will be ready to deliver those speeds.In summary: Use at least an AC1900 wireless router Be sure the router you choose has a Gigabit Ethernet WAN port. **Q: What chipset is the mb7621 utilizing? intel or broadcom or other?** A: Model MB7621 and all Motorola modems utilize the Broadcom modem chipset. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/43092883-motorola-mb8600-docsis-3-1-gigabit-cable-modem-approved-comcast](https://www.desertcart.pt/products/43092883-motorola-mb8600-docsis-3-1-gigabit-cable-modem-approved-comcast) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-01*
