Why ISPs Give Routers with Mixed 2.4GHz and 5GHz WiFi

Have you ever wondered why your internet service provider (ISP) always gives you a router that combines both 2.4GHz and 5GHz WiFi under the same network name (SSID)? If you’ve ever dealt with slow speeds, disconnects, or poor performance despite paying for high-speed internet, this is a major reason why.

ISPs Don’t Care About Your Actual Internet Speed

The harsh reality is that ISPs care more about cutting costs and minimizing support calls than actually giving you the best internet experience. When they hand you a router with a mixed WiFi mode, they are relying on “band steering”—an automatic process that decides whether your device connects to the 2.4GHz or 5GHz band. However, this system is often poorly optimized and results in your device sticking to the slower 2.4GHz band even when 5GHz is available.

Why does this matter? Because 2.4GHz, while having longer range, is crowded with interference from microwaves, Bluetooth devices, and even your neighbor's WiFi. It’s also much slower than 5GHz. But since ISPs don’t want to deal with the hassle of properly educating users, they just hand out these mixed-mode routers and let customers suffer in silence.

Customer Service is Clueless and Pushes You to Pay More

If you’ve ever called your ISP about slow WiFi, you’ve probably encountered their infuriating customer service. Instead of addressing the real issue—your device being stuck on the wrong band or interference problems—they just tell you to:

• Restart your router (which does nothing for long-term stability)
• Move closer to the router (even though 5GHz should work at the same range if properly configured)
• Upgrade your plan (which does nothing if your device is still stuck on 2.4GHz)

The reality is that ISPs don’t train their support teams on advanced WiFi troubleshooting. Most reps just follow a script and push customers toward more expensive plans rather than fixing the real issue.

How to Fix It Yourself

Since ISPs won’t help, here’s what you can do:

1. Log into your router settings: Usually, you can do this by typing 192.168.1.1 or 192.168.0.1 into your browser.
2. Disable band steering: Look for an option that forces separate 2.4GHz and 5GHz SSIDs.
3. Manually connect to 5GHz: Once the bands are separated, make sure your devices are connected to the 5GHz network whenever possible.
4. Consider buying your own router: ISP-provided routers are usually low-quality. A proper third-party router will give you better performance and more control.

Final Thoughts

ISPs could easily provide better WiFi by default, but they won’t because it’s not in their financial interest. Instead, they rely on cheap equipment, clueless customer service, and the assumption that most users won’t notice or complain. If you want the best performance, take matters into your own hands and configure your network properly. Don’t fall for the ISP’s “just pay more” scam—your slow speeds are usually their fault, not yours.
