Step by step

    Audit your current network performance

    Run a speed test at speedtest.net or fast.com while standing next to your router and again in your most distant room. Compare these results against the speed tiers outlined in your internet service provider (ISP) contract. If the drop-off is significant, the ISP's radio hardware is likely the bottleneck.

    Note: Use an Ethernet cable for your baseline test to isolate Wi-Fi interference.

    Assess your administrative requirements

    Log into your router's gateway by entering its IP address—typically 192.168.1.1 or 192.168.0.1—into your browser. Review the advanced settings; if the interface lacks options for VLAN tagging, port forwarding, custom DNS, or VPN integration, you are being limited by the ISP's restricted firmware.

    Note: Look for a sticker on the bottom of the router for the default gateway IP and credentials.

    Review the cost-benefit of hardware rental

    Examine your monthly statement for a rental or equipment fee. Often, ISPs charge $10 to $20 per month for their gateway. A high-quality consumer router pays for itself within 12 to 18 months of service while providing superior radio range and security features.

    Match hardware capabilities to your usage

    Identify your primary use case. If you stream 4K video, engage in competitive gaming, or manage a smart home with 30+ devices, you require a router with high-end MIMO streams and dedicated backhaul. ISP gateways are designed for baseline, low-density browsing and often struggle with heavy packet throughput.

    Switch to bridge mode or replace the gateway

    If you choose to use your own router, contact your ISP to set your gateway to bridge mode to prevent Double NAT issues. Alternatively, if your ISP allows, replace the unit entirely by authenticating your connection via their web portal or mobile app.

    Note: Bridge mode disables the router's Wi-Fi functions and acts strictly as a modem.
