uOS 1.32: Quick DHCP IP Renewal Option Now Available for External Interfaces

Zyxel_Claudia

As part of the usability improvements in Zyxel’s uOS 1.32 firmware, a helpful feature has been introduced for network administrators managing external (WAN) interfaces that use dynamic IP (DHCP) assignment.

New: Manual DHCP Release/Renew Button

Previously, if you needed to refresh the IP address on an external interface configured for DHCP (Get Automatically), you would have to disable and re-enable the interface.

Now, with a new dedicated button in the web GUI, you can quickly release and renew the IP address without any interruption to interface settings.

Where to Find It

Navigate to:

Network Status > Interface

For external interface that has its IP assignment method set to DHCP, you’ll now see a “Renew” icon next to it.

Clicking this button will:

• Immediately release the current IP address.
• Request a new IP address from the DHCP server (typically your ISP).

Why This Matters

This is a minor but very practical change for:

• Resolving WAN connectivity issues.
• Forcing a new IP lease from the DHCP server.
• Avoiding the need to disable interface manually, which could cause service interruptions.
