Netgear CM1100 3.1 compatibility details
I've got your Netgear cm1100 working with just one internet port, but when connected to the Nighthawk r8000 it only uses a portion of the bandwidth. The speeds drop significantly between 900Mbps and 500Mbps, and QoS settings cause unpredictable performance. There’s no built-in solution to maintain full speeds without upgrading your setup. You might need an AXR router to handle both ports efficiently and deliver consistent speeds across all Wi-Fi interfaces.
Regarding link aggregation, it relies on your ISP since firmware updates are exclusive to them. I've noticed some users report achieving speeds just over 1 GB/s. When it comes to WiFi, there are no guaranteed promises about performance.
You must first confirm whether your ISP provided the appropriate firmware. As I mentioned, even though the device can handle these features, it ultimately depends on the ISP. They control the firmware because they are the sole ones capable of updating the modem with new firmware. If you have the right firmware installed, you only need a router that supports this capability.
I received it without the Wi-Fi router, but when I collect it, it provides only half of it.
Some environment is probably misconfigured. Check for any QoS-related settings and disable them if present. If they remain active, it may indicate the router doesn’t support Gigabit internet speeds. Even though it has Gigabit ports, it doesn’t guarantee Gigabit WAN to LAN functionality—a common problem. This explains why many opt for a PF-Sense device. Please verify those configurations as well. Also, ensure firmware is up-to-date and disable any packet inspection features, as they consume significant CPU resources and can hurt performance. By the way, I heard Xfinity recently released the correct firmware for those modems, allowing both Ethernet ports to function properly. The main issue remains that they operate in separate networks rather than a unified one, possibly due to regional restrictions. However, they do provide the latest firmware updates for these devices. If needed, you could consider a router with link aggregation and use your existing router as an access point.
You require a router with a 1 Gbps WAN to LAN connection. 802.11AX refers to a wireless protocol and doesn't imply gigabit speeds for wired networks. Many users with Gigabit connections rely on devices like PF-Sense routers, as they offer stronger hardware support for those high data rates.
