ASH NET fibre settings for the ASUS RT-AC59U – VLAN 10, DHCP, no username or password.
The settings for the ASUS RT-AC59U
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 ASUS RT-AC59U 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 | http://router.asus.com or 192.168.50.1 (older models 192.168.1.1) |
| Sign in with | the admin name and password you set at first setup |
3. Set the internet connection to DHCP
- Go to WAN > Internet Connection.
- Set WAN Connection Type to Automatic IP and Authentication to None.
- Leave Get DNS automatically on, then Apply.
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
- Go to LAN > IPTV (VLAN tagging lives here on ASUS firmware, not under WAN).
- Set Select ISP Profile to Manual Setting.
- Set Internet VID (Internet VLAN ID) to 10 and Internet PRIO to 0. Leave the IPTV and VoIP rows empty.
- Apply and wait for the router to reconnect.
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 ASUS RT-AC59U (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 DSL models, first set WAN > Dual WAN or the WAN port selector to use the Ethernet WAN port rather than the phone 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.
