Linking Two Routers
Linking Two Routers
Hi everyone, The setup before was a standard Internet Supplier Router connected to multiple Deco X75 units around the house, which worked perfectly. After upgrading the bandwidth, I asked the internet supplier if I could use their own Wi-Fi 6E router, and they agreed. They now require me to connect my router to theirs, but that would likely cancel out the features of my own device. Since I already have a range-extending network from the deco, there’s no extra advantage. Should I link my router to theirs or just theirs’?
Many internet service providers require you to connect through their modem or router. Therefore, the network devices you own should work with that setup. But if your ISP offers support, you might be able to install your own modem. Whether it makes sense to set up your own router depends on your requirements and the capabilities of the ISP's device. For example, if they only provide Wi-Fi 5 while you need Wi-Fi 6E, it could be beneficial. If their router meets all your needs, it might not be necessary.
Your latest router likely lacks a modem feature, which is why you need an ISP Router for that purpose. You might set the ISP Router to "modem mode" so it only distributes internet to your router while handling everything else. Alternatively, if your new router does support modem functionality, you could bypass the ISP router entirely.
Linking two routers together is usually not recommended. A router handles two key tasks that can create problems when combined. First, it manages NAT, letting one public IP address from your ISP serve several devices. Second, it functions as a hardware firewall. Adding more layers of NAT might interfere with certain software and services, particularly for online gaming, and complicates port forwarding. The ISP you’re using is likely providing a gateway instead of a router. A gateway typically connects to a modem or media converter that also houses the router. Modems are common with DSL and cable providers, while media converters are used for fiber connections. Most ISPs offer a single device to simplify support. Changing this setup depends on local laws and the ISP’s policies. For instance, in the US, cable companies often allow customer-owned modems or gateways. If you can’t replace the ISP unit, check if it supports bridge mode. Turning that off disables the router features and leaves only a modem function. Then you can insert any router you prefer. If it doesn’t support bridge mode, consider using a WiFi 6E router as a wireless access point. In AP mode, most features except wireless capabilities are disabled, leaving it essentially as a wireless radio.
