Disable DHCP on XB-8T. How can I do this for starters
I have found I just have to many devices for the XB-8T gateway I have. The gateway is slow, and it only allows so many to be active at once.
In fact I'm wanting to setup VLANs and allow the routers I have manage their own DHCP/subnet.
Has anyone got this type of setup configured. I was told by Xfinity that if I switched to Bridge mode my bandwidth speed would drop considerably.
Thx

Hey @user_ca27d5 ,Thank you for reaching out to the Xfinity Forums Community support page. I appreciate you sharing your experience regarding your gateway connections. I'd be happy to assist you further.
It's important to note that the customization options for our gateways are limited. If you're looking for more advanced control over your network connections, you would need to consider using customer-owned equipment. You do have the option to use your own router with our gateway by placing the gateway in bridge mode.

So long as you connect your router directly to port 4 (red line above it) on the XB8, AND your router has minimum 2.5Gbe ports, plus no other restrictions, you “should” have no issue. Xfinity doesn’t throttle bandwidth or speed if you use bridge mode. Whomever told you that gave you bad information.
Also, the XB8 can handle 100 devices on each of the three bands (2.4GHz, 5GHz, and 6GHz). If you’re exceeding that, that’s dang impressive. Otherwise, you don’t have too many devices active.
What you do on your network with your devices, including routers, is totally up to you. Just don’t use bad information to influence your decision. I’d be willing to bet you’ve got other network or device issues that need to be addressed, that are not caused by Xfinity or the XB8 (unless you didn’t follow all of Xfinity’s guidelines for the XB8 settings, to include not splitting the bands, and to use WPA3-Personal-Transition only).
Good luck either way.
