The settings for the Netcomm NF18Mesh
These are the only settings ASH NET fibre needs. There is no username or password – we stopped using PPPoE in January 2026.
| Connection type | Dynamic IP / DHCP (also called IPoE or "obtain an IP automatically") |
| Username & password | None – ASH NET does not use PPPoE |
| VLAN ID | 10, tagged (802.1Q) on the internet connection |
| VLAN priority (802.1p) | 0 |
| MTU | 1500 |
| IPv6 | Optional – leave on automatic |
| Router port | The WAN / internet port, into the lit port on the fibre box (ONT) |
Step by step
1. Connect the Netcomm NF18Mesh to the fibre box
Run an Ethernet cable from the router's WAN / internet port to the activated port on your fibre box (ONT) – the port is named in your activation email and normally has a light beside it. Power the router on and connect a computer or phone to it. If you use a phone, turn mobile data off so it cannot fall back to the mobile network.
2. Open the settings
| Settings page | 192.168.20.1 (some models 192.168.1.1) |
| Sign in with | admin / admin |
3. Set the internet connection to DHCP
- Quick way: Internet Service > Ethernet WAN, then Connection Type = Dynamic IP.
- Manual way: Advanced Setup > WAN Service > Add, pick the Ethernet WAN interface (eth4), choose IP over Ethernet, then Obtain an IP address automatically.
If the router asks for a line speed, use 100/20 for Fibre 100, 500/100 for Fibre 500, 920/500 for Fibre 920, or leave it on automatic.
4. Tag the internet VLAN as 10
- On the same WAN service screen set 802.1Q VLAN ID to 10 and 802.1P Priority to 0.
- Finish the wizard and apply; the router restarts.
5. Save and reconnect
Apply the settings and give the router a minute or two – most reboot themselves. The status page should then show an internet or WAN IP address from us.
6. Check it works
Open a website, then run a speed test. If the WAN stays blank, go back over steps 3 and 4 – one of the two has not saved – and restart the router.
7. If it still will not connect
Factory reset the Netcomm NF18Mesh (hold the reset pin for about ten seconds with the power on), set it up again from step 2, and make sure you are using the port on the fibre box named in your activation email. Ex-provider routers are sometimes locked and will not show a VLAN page at all.
On the NF-series, make sure the WAN service is created on the Ethernet interface (eth4 / the red WAN port), not on the DSL line.

Routers we recommend
These arrive set up for ASH NET – plug them into the fibre box and they work. On a 12-month plan you can rent one for $7.50 a month instead of buying.
