✓Restart your router and modem
✓Use [speedtest.net](https://speedtest.net) to check speeds
✓Optimize router placement
✓Switch Wi-Fi bands
✓Flush DNS cache
✓Contact your ISP as a last resort

To fix slow Wi-Fi, follow this structured approach, starting with the simplest fixes and progressing to more advanced solutions if necessary:

1. Restart Your Network Equipment

·Unplug both your modem and router, wait 60 seconds, and plug them back in. This refreshes your connection to your ISP and clears temporary glitches.

2. Run an Internet Speed Test

·Use speedtest.net to check speeds over Wi-Fi. If speeds are significantly lower than your ISP's advertised plan, the issue is likely with your home network.

3. Optimize Your Router's Placement

·Place your router in a central, elevated location, away from thick walls, metal objects, and electronics that cause interference (e.g., microwaves, Bluetooth speakers).

4. Manage Your Wi-Fi Bands and Channels

·For dual-band routers, connect devices that need speed and are close by to the 5 GHz band. Use the 2.4 GHz band for devices farther away.
·Log into your router's admin panel (often at 192.168.1.1 or 192.168.0.1) and switch to a less crowded channel, especially on the 2.4 GHz band.

5. Reduce Network Congestion

·Disconnect unused devices and schedule heavy tasks like large downloads during off-peak hours.
·Enable Quality of Service (QoS) settings in your router to prioritize critical traffic such as video calls or gaming.

6. Update Your Equipment

·Ensure your router’s firmware is up to date by checking the admin panel.
·Update the software on your devices and consider upgrading older routers to newer models like Wi-Fi 6 or mesh systems.

7. Advanced Checks

·Flush your DNS cache (on Windows, use ipconfig /flushdns in Command Prompt) to resolve webpage loading issues.
·Consider changing your DNS server to a faster public option like Cloudflare (1.1.1.1) or Google DNS (8.8.8.8).
·Factory reset your router as a last resort, but be aware this will erase all custom settings.

8. Contact Your Internet Service Provider (ISP)

·If none of the above steps help, contact your ISP to check for outages, verify your plan, or inquire about possible upgrades.

Quick Reference Flow:

Start with Restart → Speed Test → Router Placement → Band/Channel → Network Congestion → Equipment Update. If the problem persists, perform Advanced Checks or Contact Your ISP. By methodically working through these steps, you can identify and resolve most common causes of slow Wi-Fi.
