Networking troubleshooting guide

Fix Wi-Fi That Keeps Disconnecting

Separate local Wi-Fi issues from DNS, DHCP, roaming, mesh, or ISP problems.

Use this guide for intermittent disconnects, flaky DNS, packet loss, slow roaming, or wired-vs-wireless mismatch issues.

Quick symptom scan

Quick checks first

1Check for bad DNS, duplicate IPs, or captive portal residue before blaming hardware.
2Disable VPN or traffic filtering temporarily to see if the disconnects stop.
3Review roaming/mesh behavior if the issue appears while moving between access points.
4Escalate to modem or ISP checks when the gateway itself becomes unstable.
