Get More From Your Existing Setup
A new router isn't always the answer. In many cases, poor WiFi performance comes down to placement, configuration, or interference — all things you can address without spending anything. Here are seven effective changes you can make today.
1. Reposition Your Router
Router placement is the single most impactful thing you can change. WiFi signals radiate outward from the router in all directions, so placing it in a corner or closet wastes most of that signal.
Do this: Move your router to a central location in your home, ideally elevated (like on a shelf rather than the floor), with clear line-of-sight to the areas you use most. Keep it away from thick walls, metal objects, and appliances.
2. Switch to a Less Congested WiFi Channel
On the 2.4 GHz band, channels 1, 6, and 11 are the only non-overlapping options. If your neighbors are all on channel 6, switching to channel 1 or 11 can significantly reduce interference.
Do this: Use a free WiFi analyzer app (available on Android and desktop) to see which channels are most congested in your area. Then log into your router and manually select a quieter channel. On 5 GHz, there are many more channels — automatic selection usually works well there.
3. Separate Your 2.4 GHz and 5 GHz Networks
Many routers broadcast both bands under the same network name. While convenient, this means your devices may connect to the slower 2.4 GHz band when they'd perform better on 5 GHz.
Do this: Give each band a distinct name (e.g., "HomeNet_2.4" and "HomeNet_5G") so you can deliberately connect devices to the best band. Use 5 GHz for laptops, phones, and streaming devices in the same room. Use 2.4 GHz for smart home devices and anything far from the router.
4. Update Your Router's Firmware
Firmware updates often include performance improvements and bug fixes that can meaningfully improve WiFi behavior. Many routers ship with outdated firmware right out of the box.
Do this: Log into your router's admin panel and check the firmware section. Apply any available updates. Enable automatic updates if the option exists.
5. Reduce Interference From Other Devices
Microwaves, baby monitors, older cordless phones, and Bluetooth devices all operate in the 2.4 GHz spectrum and can cause significant interference with your WiFi signal.
Do this: Keep your router physically separated from these devices. If interference is a persistent problem, migrating your devices to the 5 GHz band (which isn't affected by most of these sources) is the most effective fix.
6. Adjust Your Router's Transmit Power
Some routers allow you to adjust transmit power in the admin settings. If it's set lower than maximum, you may be artificially limiting your range. Conversely, in some environments, reducing power can actually improve network quality by reducing cross-channel interference.
Do this: Find the transmit power setting in your router's wireless advanced settings and experiment. Most home users benefit from setting it to the maximum.
7. Reboot Your Router Regularly
Routers can develop memory leaks, stale routing tables, and congested connection logs over time. A simple reboot clears all of this and often restores performance noticeably.
Do this: Set a monthly reminder to reboot your router, or check if your model supports scheduled reboots in its settings. Some routers also let you configure this automatically (e.g., every Sunday at 3am when no one is online).
Summary Table
| Tip | Difficulty | Potential Impact |
|---|---|---|
| Reposition router | Easy | High |
| Switch WiFi channel | Moderate | High (in congested areas) |
| Separate 2.4 / 5 GHz | Moderate | Medium–High |
| Update firmware | Easy | Medium |
| Reduce interference | Easy | Medium |
| Adjust transmit power | Moderate | Low–Medium |
| Reboot regularly | Easy | Low–Medium |
When It's Time for New Hardware
If you've worked through all of these tips and still struggle with coverage or speeds, the issue may genuinely be hardware. A router that's several years old, or an internet plan that's simply too slow for your household's needs, won't be fixed by configuration alone. At that point, it's worth considering a mesh WiFi system or a router upgrade.
