Wi-Fi connected but no internet on only one laptop

Scenario

One laptop connects to office Wi-Fi with a valid SSID and signal, but web traffic fails while other devices work.

Recommended Resolution Path

1. Forget and re-add the wireless network to clear profile corruption.
2. Test DHCP lease, default gateway, and DNS resolution from the affected laptop.
3. Disable IPv6 temporarily to isolate edge-case network stack issues.
4. Update the wireless driver and review vendor power management settings.

Technician Notes

Confirm the business impact, document the root cause, and capture any preventative follow-up in the PSA or client knowledge base.
