Congested channels cause disconnections:

For 2.4GHz: Use channel 1, 6, or 11 (non-overlapping) For 5GHz: Try different channels

Use a WiFi analyzer app to find the least congested channel.

Disable Band Steering

Some routers aggressively move devices between bands:

1. Log into router admin
2. Find band steering or smart connect
3. Disable it
4. Connect to specific band (2.4GHz or 5GHz)
