关于Eero Pro 6e路由器连接网络交换机及DHCP、静态IP配置的技术咨询

Hey Riley, let's walk through your questions and help get that basement lab connected properly:

关于DHCP是否需要禁用的问题 #

First off, let's clarify the right topology for your setup (this will clear up the DHCP confusion):

• Keep your Arris S33 in bridge mode (most ISPs set this by default, but if not, you can log into the modem's admin page—usually at 192.168.100.1—to switch it to bridge mode. This lets the Eero handle PPPoE dialing and network management).
• Connect the S33's Ethernet output to one port on your YuanLey switch.
• Run your Cat 6e cable from another switch port to the WAN port of your Eero Pro 6e (not a LAN port).
• Plug your basement server, printers, etc., into the remaining switch ports.

In this setup, the Eero acts as your main router, so you do NOT need to disable DHCP on it. The Eero will assign IP addresses to all devices (both your upstairs Wi-Fi devices and basement wired gear) automatically, and everything will be on the same network (so your basement devices can access Wi-Fi resources if you want).

You only need to disable DHCP on the Eero if you were using it as a secondary access point (i.e., plugging its LAN port into the switch while another router handles DHCP)—that's not your use case here.

如何在Eero上设置静态IP #

Setting static IPs via the Eero App is straightforward, here's how:

• Open the Eero App and tap the Devices tab at the bottom.
• Locate the device you want to assign a static IP to (make sure it's already connected to your Eero network, either wired or wireless).
• Tap into the device's detail page, then find and tap the IP Address option.
• Switch the toggle from "Dynamic" to "Static".
• Enter the static IP you want to use (make sure it's within your Eero's DHCP range—default is usually 192.168.1.10 to 192.168.1.254 or similar, and avoid using an IP that's already assigned to another device).
• Save the changes, and the device will now use that static IP permanently.

If you need to check your Eero's DHCP range (to pick a safe static IP), you can go to Settings > Network Settings > IP Address in the app to see the subnet and available range.
