You manage them in a browser at `192.168.1.1`; the sign-in screen offers a choice of language, and DIGI’s manuals quote the Spanish labels. DIGI router Sign in `192.168.1.1` App Mi DIGI (account only) Password The user name is `user`. DIGI’s current manuals say the password is printed on the router’s label, and the router makes you change it at the first sign-in. Models ZTE ZXHN F6705, ZTE ZXHN H3600, ZTE ZXHN F8648P, ZTE ZXHN H3600P **Checked 1 November 2026.** ZTE ZXHN F6705 and H3600 as supplied by DIGI Spain, from DIGI’s 2025 user manuals; the F8648P and H3600P use the same ZTE interface. DIGI also hands out TP-Link, Zyxel, Huawei, Comtrend and other models, each with its own manual on DIGI’s guides page. Labels are given in Spanish with an English gloss. ## Sign in to the DIGI router **Factory default.** DIGI’s quick-start guides and its FAQ give `user` as both user name and password on older units. Change it at the first sign-in, as the router asks. 1. Connect your Mac to the router by Wi-Fi or an Ethernet cable; DIGI recommends a computer. 2. Open `http://192.168.1.1` in your browser and press Return. 3. Pick your language at the top right of the sign-in screen. 4. Enter `user` and the password from the label, then click **Iniciar sesión** (Sign in). 5. The first time, set a new password when the router asks. Forgotten the password you set? Hold the **Reset** button for at least 10 seconds on the H3600 (5 seconds on the F6705). That restores factory settings, including the Wi-Fi name and password. ## Restart it properly DIGI’s manuals restart the router with its On/Off switch. After activating Conexión Plus, DIGI also asks you to restart the router so it picks up the new public IP address. 1. Switch the router off with the **On/Off** button on the back. 2. Wait a few seconds, then switch it back on. 3. Wait a few minutes until the **Internet** light is steady. Don’t use the **Reset** button to restart: holding it returns the router to factory settings. ### Schedule a restart DIGI’s manuals document no scheduled or web-interface restart. **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 DIGI’s manuals don’t describe checking or installing router software. On the F6705, a slowly flashing green **PON** light means the router is updating, so DIGI pushes updates itself. ## See connected devices 1. Sign in at `http://192.168.1.1`. 2. Read the main screen, which lists devices connected by Wi-Fi (**WLAN**) and by cable (**LAN**). 3. To limit a device’s hours, open **Internet › Controles Parentales** (Parental controls) in the left menu. 4. Switch a rule to **Encendido** (On), pick the device and the days and times, then click **Aplicar** (Apply). **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 DIGI uses CG-NAT, so by default your router shares a public IPv4 address with other customers. Ports can’t be opened from outside until you add DIGI’s Conexión Plus (1 € a month), which gives you your own dynamic public IP. DIGI’s manuals for the ZTE routers don’t mention UPnP IGD or NAT-PMP, so open ports by hand as below. DIGI warns that opening ports can put your devices at risk, and that DMZ exposes one device fully. Open only the ports a game or app needs, and close them when you’re done. ### Open ports by hand Activate Conexión Plus in Mi DIGI under **Productos** (Products) or by calling 1200, then restart the router. Give the target device a fixed IP address first. 1. Sign in and open **Internet** in the top menu, then **Seguridad** (Security) on the left. 2. Open **Reenvío de puertos** (Port forwarding); older firmware calls it **Port Forwarding**. 3. Enter a **Nombre** (Name), the **Protocolo** (TCP, UDP or both) and the device’s IP address. 4. Enter the ports under **WAN Port** and **LAN Host Port**, switch the rule on and click **Aplicar**. Ports 443, 21, 80 and 7547 can’t be opened because DIGI uses them to manage the router. Port 25 needs a request to DIGI. **Kilobat can help.** Without UPnP traffic counters, Kilobat’s [call reports](https://kilobat.app/video-calls) still name a busy app on your Mac or a Wi-Fi problem, but can’t point at another device at home. ## Prioritise calls and gaming DIGI’s manuals list QoS as a feature of the F6705 but document no setting to prioritise devices or traffic. **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 The routers broadcast separate 2.4 GHz and 5 GHz networks. On the F6705, MLO (on by default) adds a Wi-Fi 7 network that uses both bands at once. 1. Sign in and open **Red local** (Local network) in the top menu. 2. Click **WLAN › WLAN Básico › Configuración WLAN SSID** (Basic WLAN › WLAN SSID settings). 3. Pick the 2.4 GHz or 5 GHz network and make sure it is **Encendido** (On). 4. Change **Nombre SSID** (Network name) or **Frase de contraseña WPA** (WPA passphrase), then click **Aplicar**. ### Change the channel 1. Open **Red local › WLAN**. 2. Open **Wi-Fi periférica** (F6705) or **Radar WLAN** (H3600) to see nearby networks’ channels. 3. Open **Configuración Global WLAN** (Global WLAN settings) for 2.4 GHz or 5 GHz and pick a channel. 4. Click **Aplicar**. DIGI recommends channels 1, 6 or 11 on 2.4 GHz and 36, 40, 44 or 48 on 5 GHz. ### Turn MLO off (F6705) 1. Open **Red local › WLAN › MLO**, set it to **Apagado** (Off) and click **Aplicar**. 2. After the router restarts, switch off SSID 2 and SSID 6 under **Configuración WLAN SSID**. **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 DIGI’s manuals for these routers document no mesh or repeater setup. DIGI does offer an extra-router service, NEO WIFI, but its help pages don’t describe how to set it up. **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 The router has eight network slots, four per band; one of each is on by default. A guest network is simply another slot switched on. 1. Sign in and open **Red local › WLAN › WLAN Básico › Configuración WLAN SSID**. 2. Expand a network that is **Apagado** (Off) and switch it to **Encendido** (On). 3. Set its **Nombre SSID** and **Frase de contraseña WPA**. 4. Click **Aplicar**. On the F6705 with MLO on, SSID 2 and SSID 6 are already used by the MLO network. DIGI’s manuals don’t say whether the extra networks are isolated from your home network. **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 DIGI’s manuals document no way to change the DNS servers the router hands out. Set custom DNS on the Mac instead. **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; steady means connected, and red on the H3600 means the router failed to get an IP. 2. On the F6705, a steady or flashing red **LOS** light means a fibre signal problem. 3. Sign in; the main screen shows the WAN connection and connected devices. 4. Run DIGI’s [speed test](https://www.digimobil.es/test-de-velocidad) to check your line speed. DIGI’s manuals don’t describe an event log or line statistics page. **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. ## Manuals and downloads - [DIGI: ZTE ZXHN F6705 user manual (PDF, Spanish)](https://www.digimobil.es/downloads/manual-zte-zxhn-f6705) - [DIGI: ZTE H3600 user manual (PDF, Spanish)](https://www.digimobil.es/downloads/manual-zyxel-zte-zxhn-h3600) - [DIGI: user guides for every router](https://www.digimobil.es/guias) - [DIGI: Fibra help and FAQ](https://www.digimobil.es/preguntas-frecuentes/fibra) Links go to the maker’s own pages. ## Questions **Why can’t I open ports on my DIGI router?** DIGI uses CG-NAT, so you share a public IP with other customers. Add Conexión Plus (1 € a month) in Mi DIGI, restart the router, then set up port forwarding. **Can I use my own router with DIGI?** Yes. Call DIGI for the PPPoE details; fixed-line phone service then won’t work, except with a ZTE F6705 in bridge mode, which DIGI documents separately. ## Sources - [DIGI: Manual de usuario ZTE ZXHN F6705](https://www.digimobil.es/downloads/manual-zte-zxhn-f6705) - [DIGI: Manual de usuario ZTE H3600](https://www.digimobil.es/downloads/manual-zyxel-zte-zxhn-h3600) - [DIGI: Guía rápida de instalación ZTE H3600](https://www.digimobil.es/downloads/guia-zyxel-zte-zxhn-h3600) - [DIGI: Guía para la apertura de puertos ZTE](https://www.digimobil.es/downloads/guia-apertura-puertos-zte) - [DIGI: Preguntas frecuentes, Fibra (CG-NAT, router settings, own router)](https://www.digimobil.es/preguntas-frecuentes/fibra) - [DIGI: Servicios adicionales (Conexión Plus, NEO WIFI)](https://www.digimobil.es/servicios-adicionales) - [DIGI: Guías de usuario](https://www.digimobil.es/guias) Checked on 1 November 2026. ## 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.
