Important: EX3920 is a kit containing two AC750 extender units based on the EX3700 platform. Treating EX3920 as one unique single extender can lead to confusing setup instructions.

What comes with EX3920?

NETGEAR’s documentation identifies EX3920 as an AC750 WiFi Range Extenders kit and support notes describe it as a combination of two EX3700 extenders. Each extender is configured and positioned as an individual unit.

Set up the first extender

Configure one unit close enough to the router for a reliable initial connection. You can use the supported WPS workflow or browser-based setup. After confirming internet access through the extended network, move that unit to its intended coverage location.

Set up the second extender separately

Repeat the process for the second unit. Do not assume that configuring one automatically configures the other. Give attention to placement so the two extenders solve separate coverage gaps rather than simply overlapping heavily in the same area.

Browser management

NETGEAR’s EX3920 manual documents local browser management through MyWiFiExt and Smart Setup for changing the router connection, extended network name or password. After the extender joins the home network, its actual local IP can also be relevant for management.

Firmware

NETGEAR firmware notices for EX3700/EX3800/EX3920 explain that EX3920 uses the EX3700 firmware platform. Follow the official firmware package and instructions for the kit/platform and do not interrupt power during an update.

Plan the two units as separate coverage cells

Because EX3920 is a two-extender kit, avoid installing both units in the same marginal area. Configure and test each unit individually, then use them to address distinct coverage gaps. Each unit still needs a usable router signal; two extenders placed deep inside two dead zones simply create two weak backhauls.

Ethernet and access-point use

NETGEAR’s current access-point guidance includes EX3920. Where Ethernet is available, a unit can be deployed as an access point rather than relying on wireless repeating. In extender mode, an Ethernet-connected client still depends on that unit’s wireless link back to the router.

Local login for each unit

Manage the unit you intend to change while connected to its network. NETGEAR’s current login guidance includes EX3920 and distinguishes between the local hostname route and using the extender’s assigned IP when the router and extender share an SSID. With two units installed, identifying the correct local device is especially important.

Firmware consistency across the kit

NETGEAR groups EX3920 with the EX3700/EX3800 platform in support material. Check the exact support package before updating either unit and allow each update/restart to complete independently. Do not assume that updating one physical extender automatically updates the other.
