Optimize Router Settings

Your router configuration plays a huge role in connection stability. Log in to your router admin panel (usually 192.168.1.1 or 192.168.0.1) and check these settings.

Change the Wi-Fi Channel

Congested channels cause interference. Use a Wi-Fi analyzer app to find the least crowded channel, then set your router to use it. For 2.4 GHz, channels 1, 6, and 11 are usually best. For 5 GHz, choose a channel with low usage.

Choose the Right Band

If your router supports dual-band, try connecting to 5 GHz for less interference (shorter range) or 2.4 GHz for better range (more interference). Some devices handle one band better than the other.

Adjust Beacon Interval and DTIM

Setting the beacon interval to 100 ms and DTIM to 1 or 2 can improve stability for many devices. These are found under advanced wireless settings.

Update Router Firmware

Manufacturers release firmware updates that fix bugs and improve stability. Check your router’s admin panel for an update option, or visit the manufacturer’s website.
