Use safely: Follow these steps only for a router or network you own or are authorised to manage. Never send Router Portal a router password, Wi-Fi key, MAC address, serial number or private screenshot.

Quick answer: A connection that works initially but drops during renewal can point to lease timing, a sleeping client, a changing VLAN, a firewall rule or an unstable DHCP service.
What this page covers
Compare the time of failure with lease details and test another client on the same network.
Step-by-step workflow
- Note the approximate failure time and interface.
- Inspect lease obtained, expiry and DHCP-server fields.
- Compare wired and Wi-Fi clients if both are available.
- Review router logs only after redacting private identifiers.
Decision table
| Check | What it tells you | Safe next action |
|---|---|---|
| All clients renew poorly | DHCP service or upstream path | Check router and provider status |
| One client only | Adapter, driver or sleep behavior | Update or reset only that profile |
| Network changes at renewal | VLAN/bridge or roaming transition | Review topology and logs |
Limits and verification
Lease durations and UI labels differ by router. Do not publish a universal lease time as a fix.
