# Elisa modem login, restart, firmware and UPnP

Elisa supplies Zyxel modems and routers with its home broadband in Finland, such as the Wi-Fi 6 EX5501 router and the DX3300-T0 DSL modem. You manage them in a browser at `192.168.1.1`; Elisa says DX3300-T0 settings can also be changed remotely through OmaElisa.

Elisa modem (Zyxel)

Sign in

`192.168.1.1`

App

OmaElisa (remote management)

Password

The user name is `admin`. The password is on the label on the back of the device, next to **Login Password**; the Wi-Fi name and key are on the info card or the label underneath.

Models

Zyxel EX5501, Zyxel DX3300-T0

**Checked 1 November 2026.** Zyxel EX5501 and DX3300-T0 as supplied by Elisa, from Elisa’s device pages and the Zyxel AX/DX/EX/PX series user’s guide Elisa links for the EX5501 (firmware 5.15–5.17). Elisa’s firmware may hide some menus. Elisa also hands out TP-Link, Huawei and cable modems with other addresses; check the label. The web interface is in English.

## Sign in to the Elisa modem (Zyxel)

1. Connect your Mac to the modem with an Ethernet cable or by Wi-Fi.
2. Open `http://192.168.1.1` in your browser.
3. Enter `admin` and the **Login Password** from the label, then log in.
4. The first time, set a new password and click **Apply**.

Forgotten the password? Press the reset button on the back for about 10 seconds with a straightened paper clip. That restores the label password and factory settings. Elisa’s TP-Link VX800v uses `192.168.100.1` instead.

## Restart it properly

1. Sign in and click the **Restart** icon at the top right of the navigation panel.
2. Or open **Maintenance › Reboot** and click **Reboot**.
3. Wait a few minutes until the Internet light is lit again.

Elisa recommends a factory reset if problems continue after a software update, because old settings can linger until a reset.

### Power cycle

1. Switch the modem off for about 10 seconds.
2. Switch it back on and wait for the connection to return.

### Schedule a restart

Elisa and Zyxel document no scheduled restart for these models.

**Kilobat can help.** Kilobat Pro’s [router check-up](https://kilobat.app/docs/home-network#router-checkup) learns how fast this router usually answers, says when a restart is due, and checks the next day whether it helped.

## Update the firmware

Elisa sends new software to DX3300-T0 modems bought from Elisa automatically; keep automatic updates on in the device settings. Elisa says no software updates are available for the EX5501.

1. Sign in, open **Connection Status** and click the arrow on **System Info** to see the **Firmware Version**.
2. Compare it with the version list on Elisa’s page for your model.
3. Leave the modem on; a blinking red power light on the DX3300 means an update is running.

Zyxel’s guide describes manual uploads under **Maintenance › Firmware Upgrade**, but Elisa doesn’t publish firmware files for its modems.

## See connected devices

1. Sign in and open **Connection Status**.
2. On the **Connectivity** card, click the arrow to see the IP and MAC addresses of wired and wireless devices.
3. Hover over a device and click its edit icon to change its name or icon, then click **Save**.
4. For Wi-Fi details, open **System Monitor › WLAN Station Status**.

**Kilobat can help.** Kilobat’s [new-device alerts](https://kilobat.app/docs/home-network#new-devices) tell you when a device you haven’t seen joins your home Wi-Fi. **Tools › Devices** lists what answers on the network, and you can name each one.

## UPnP and port forwarding

The Zyxel firmware supports UPnP IGD 1.0. UPnP lets devices discover the router; UPnP NAT-T lets apps open ports themselves. Both are separate switches.

1. Sign in and open **Network Setting › Home Networking › UPnP**.
2. Switch **UPnP** on or off.
3. Switch **UPnP NAT-T** on if games or apps should open ports automatically.
4. Click **Apply**. Ports opened by apps appear in the table on the same screen.

Zyxel warns that anyone could use a UPnP app to open the Web Configurator’s login page to the internet, and that UPnP devices talk freely to each other. Turning on WPS also turns UPnP on. Leave UPnP NAT-T off unless something needs it.

### NAT-PMP

Zyxel’s guide documents UPnP IGD only, not NAT-PMP.

### Fixed port forwards

1. Open **Network Setting › NAT › Port Forwarding** and add a rule for the device and ports.

**Kilobat can help.** On supported routers, Kilobat’s [call reports](https://kilobat.app/video-calls) can read available traffic counters, read-only, to identify another device that was busy when a call froze. Correlation does not prove the cause. Kilobat never opens ports.

## Prioritise calls and gaming

1. Sign in and open **Network Setting › QoS › General**.
2. Enable QoS and set the **WAN Managed Upstream Bandwidth**, or leave it empty to use the line rate.
3. Pick how **Upstream Traffic Priority** is assigned, or **None** to use your own rules.
4. Add rules under **Queue Setup** and **Classification Setup** if needed, then click **Apply**.

Elisa’s own pages don’t cover QoS; these paths come from Zyxel’s guide.

**Kilobat can help.** Run Kilobat’s [stutter test](https://kilobat.app/guides/recipes/test-call-stutter) before and after you change priorities, to see whether calls really got smoother.

## 2.4 and 5 GHz, and the channel

With **Keep the same settings for 2.4G and 5G wireless networks** selected, both bands share one name and password. Clear it to give each band its own network.

1. Sign in and open **Network Setting › Wireless › General**.
2. Clear **Keep the same settings for 2.4G and 5G wireless networks**.
3. Set a name and password for each **Band**, then click **Apply**.

### Change the channel

1. In **Network Setting › Wireless › General**, choose a **Channel**, or **Auto**.
2. Click **Apply**.
3. To see which channels are busy, run a scan under **Wireless › Channel Status**.

Elisa says some Wi-Fi adapters handle automatic channel changes badly; if Wi-Fi keeps dropping, set a fixed 2.4 GHz channel between 1 and 11.

**Kilobat can help.** Kilobat shows which band and channel your Mac is on, and `kilobat channels` suggests the least crowded channel. More in [crowded Wi-Fi channels](https://kilobat.app/guides/wifi-channel-congestion) and [Wi-Fi on a Mac](https://kilobat.app/wifi-analyzer-mac).

## Mesh: which node a device uses

Elisa’s Kotiverkko (home network) service adds Huawei K572 mesh extenders, set up on their own admin page.

1. Plug in the first extender and connect it to the modem’s LAN port with an Ethernet cable.
2. Join the extender’s Wi-Fi; the name and password are on the label underneath.
3. Open `https://192.168.100.1`, or `https://192.168.101.1` behind a modem, and accept the browser warning.
4. Enter the password from the extender’s label; network setup starts automatically.

The Zyxel firmware also has **Network Setting › Wireless › MESH** for Zyxel MPro Mesh extenders, with band and AP steering.

**Kilobat can help.** When your Mac moves to another node or band, Kilobat’s Health says so, so a weaker node isn’t taken for a router problem. See [find a better Wi-Fi spot](https://kilobat.app/guides/recipes/find-better-wifi-spot).

## Guest network

1. Sign in and open **Network Setting › Wireless › Guest/More AP**.
2. Click the edit icon next to a spare network.
3. Tick **Guest WLAN** and choose **External Guest** so guests can’t reach each other.
4. Set the name and password, then click **OK**.

Guest networks reach the internet only, not your home devices. The **Connection Status** page also has a quick guest Wi-Fi switch.

**Kilobat can help.** Kilobat can show a network as a QR code, so guests join with their phone’s camera: [share Wi-Fi with a QR code](https://kilobat.app/guides/recipes/share-wifi-qr-code).

## DNS settings

1. Sign in and open **Network Setting › Home Networking › LAN Setup**.
2. Under **DNS Values**, set **DNS** to **Static**.
3. Enter **DNS Server 1** and **DNS Server 2**, which the modem hands to your devices.
4. Click **Apply**.

The DNS fields only appear while the DHCP server is enabled. A wrong address cuts off name lookups for every device.

**Kilobat can help.** Before you change DNS, [compare resolvers with Kilobat](https://kilobat.app/guides/recipes/pick-faster-dns) to see which answers fastest from your home.

## Connection status and logs

1. Check the Internet light; blue on the DX3300 means connected, red means an internet fault.
2. Open **System Monitor › Log › System Log** for events such as connection drops.
3. On a DSL line, open **System Monitor › xDSL Statistics** for sync rates and errors.
4. Use **Maintenance › Diagnostic** for ping, traceroute and nslookup tests.

For faults, Elisa’s Verkkoapuri (network helper) checks known problems in your area.

**Kilobat can help.** When the line keeps dropping, Kilobat’s [provider report](https://kilobat.app/docs/health#report) lists outages, latency and speed tests against your plan, ready to send to your provider.

## Questions

**Which address is my Elisa modem on?**

The Zyxel EX5501 and DX3300-T0 use `192.168.1.1`. Other Elisa devices differ, for example `192.168.100.1` on the TP-Link VX800v; the label shows the address and password.

**Should I bridge my Elisa modem?**

Elisa advises against it unless you need to. Bridged, the modem passes all traffic to your devices, and only four public IP addresses remain for them.

## See what your router can’t tell you

Kilobat is a Mac menu-bar app that watches the network from your side: which app is using it, whether the Wi-Fi, the router or the provider is slow, and why a call froze.
