WiFi Mesh Setup: ASUS ZenWiFi AX Mini 802.11ax Mini (XD4) Network Extension or TP-Link Deco X20 AX1800
Upgraded to Fiber optics at 1000Mbps yesterday. Router is a Sagemcom model 5670 with Wi-Fi 6. Signal isn’t reaching the upstairs area. Looking into mesh systems for improved coverage. Price variations exist—cheapest X20 decoy system on Amazon UK was £140, while the ASUS option was around £300/€300. Also considering replacing the current Sagemcom 5670 router, which we’re paying €5/month to use. Thanks for your assistance!
Several aspects need clarification here... Initially, swapping any ISP equipment for a personal version must be approved with the provider first. Their stance varies—some permit it, others do not. If permitted, you’ll either need an approved model or secure authorization from them on their network. In certain areas, like the United States, most cable internet users can modify their modems, though fiber providers are less likely to allow such changes.
Secondly, contemporary ISPs typically offer integrated gateways that combine multiple functions—routers, media converters, modems, APs, and switches—into a single unit. Changing the ISP device means swapping out all these components. For connections arriving at your residence via fiber ports, a standard wireless router won’t function properly. You’ll likely need a fiber-to-Ethernet converter or adjust the gateway’s settings to operate in bridge or passthrough mode. These settings essentially instruct the gateway to mimic a modem and forward traffic directly to your router. Such adjustments often disable firewall and AP capabilities, though modern routers usually retain these features.
Thirdly, determining which mesh network setup is superior is challenging. Many variables influence WiFi performance, especially home layouts. Physical barriers like walls and floors—such as brick, concrete, or steel—strongly impact signal strength. The only reliable way to assess this is through testing. From my experience in regions with concrete interiors and steel reinforcements, mesh networks often perform inconsistently. In contrast, homes with wooden interior walls tend to see better results. A multi-AP configuration has proven effective for me. It’s not a universal rule, but when multiple mesh nodes are used, especially tri-band models, they can handle complex environments. Tri-band systems cost more but allocate one 5GHz channel for wireless backhaul while reserving another for high-speed client connections. Ultimately, if you can establish Ethernet links between rooms or floors, a mesh network operating in AP mode remains viable. The wired connection offers far greater stability than wireless, and you won’t face interference issues across nodes.
I purchased Asus's ZenWiFi AX Mini 802.11ax Mini (XD4) Mesh Wireless, and I'm wondering which router to buy to swap in for my current Sagemcom f@st 5670. Both should fit the mesh setup. Besides the media converter, what else do I need, keeping in mind my ISP might remove their device along with the cables?
You've checked with your ISP about swapping the Sagemcom device for your own setup. If they confirm you can use a different router, inquire about attaching your own wireless access point. The situation with the Sagemcom f@st 5670 seems unclear from the photos—likely its fiber connection ends elsewhere, meaning the media converter is already installed. You may need to locate that source or contact your ISP directly. If the device does have fiber connections, simply replacing the ONT isn't possible unless your provider approves alternatives. I regret not being able to provide precise guidance without knowing your location and ISP details. A fellow forum member using the same service could offer more targeted advice. I'll tag @Alex Atkin UK to check for suggestions.
I confirmed with them earlier and they mentioned it’s possible to replace it. You’ll notice a fiber input in the attached photo. Although we’re not part of the EU, the ISP does allow you to switch to your own equipment. If you need any clarification, Bezeq Benleumi is the provider.
This indicates your ISP equipment is also an ONT. You'll need to contact Bezeq Benleumi to discover suitable replacements for ONT or media converters. They'll also supply the required setup instructions for connecting your device to their network.
