FAQ
TL;DR: Orange FTTH over an ONT uses VLAN 35 with PPPoE; "requires PPPoE and VLAN 35." Choose a router that tags VLANs on the WAN. [Elektroda, makosuu, post #17105407]
Why it matters: This helps Orange fiber users decide whether to reuse a TP‑Link W9980 or pick alternatives like Archer models, and how to set them up.
Quick Facts
- TP‑Link W9980 can act as a WAN router via Operation Mode > Wireless Router Mode, using the LAN/WAN port. [Elektroda, jimasek, post #17100587]
- Orange FTTH behind an ONT authenticates with PPPoE and VLAN ID 35 for Internet service. [Elektroda, makosuu, post #17105407]
- On the W9980, VLAN settings disappear on the Ethernet WAN when in Wireless Router Mode. [Elektroda, zdzlh, post #17104134]
- Archer C1200 was confirmed to work on Orange FTTH; W9980 failed due to no VLAN-on-WAN. [Elektroda, zdzlh, post #17116603]
- Funbox 2.0 pairs with an external ONT, while Funbox 3.0 integrates the ONT in one unit. [Elektroda, makosuu, post #17105439]
Can a TP‑Link W9980 work with Orange fiber over an ONT?
No in this case. The W9980 lacks VLAN tagging on the WAN port when used as an Ethernet WAN, so it could not connect. The OP replaced it for that reason. [Elektroda, zdzlh, post #17116603]
Do I need VLAN 35 and PPPoE with Orange FTTH?
Yes. Orange fiber delivered via an ONT authenticates using PPPoE and VLAN ID 35. As one expert put it: "requires PPPoE and VLAN 35." This applies for Internet service, and you should prepare credentials from Orange. [Elektroda, makosuu, post #17105407]
Where do I enable WAN mode on a TP‑Link W9980?
Open Operation Mode and select Wireless Router Mode. Use the LAN/WAN labeled port for the ONT handoff. This enables standard WAN types like Dynamic IP, Static IP, or PPPoE. [Elektroda, jimasek, post #17100587]
Why cant I set a VLAN ID after switching the W9980 to Wireless Router Mode?
On this model, the VLAN option is available in xDSL mode only. After switching to Wireless Router Mode, the VLAN selection disappears, so you cannot tag the Ethernet WAN. [Elektroda, zdzlh, post #17104134]
Which replacement router actually worked here with Orange FTTH?
The TP‑Link Archer C1200 worked and was confirmed by the OP. The W9980 did not, due to no VLAN tagging on the WAN. [Elektroda, zdzlh, post #17116603]
Will an Archer C7 work with Orange fiber?
It can if its firmware tags 802.1Q VLAN on the WAN. Verify VLAN-on-WAN support before buying. If unsure, consider a model known to work here, like the Archer C1200. [Elektroda, zdzlh, post #17116603]
Is Dynamic IP enough behind the ONT, or must I use PPPoE?
Use PPPoE. Oranges ONT expects PPPoE with VLAN 35 for Internet. Choosing Dynamic IP will fail to authenticate and wont get you online. "Requires PPPoE and VLAN 35." [Elektroda, makosuu, post #17105407]
How do I switch the W9980 to Ethernet WAN mode?
- Go to Operation Mode and select Wireless Router Mode.
- Connect the ONT to the LAN/WAN port on the W9980.
- In WAN settings, choose your WAN type (e.g., PPPoE) and enter credentials.

Whats the ONT difference between Funbox 2.0 and 3.0?
Funbox 2.0 works with an external ONT. Funbox 3.0 has an integrated ONT. If you replace Funbox 2.0, your new router must connect to the separate ONT. [Elektroda, makosuu, post #17105439]
I only need Internet (no TV/VoIP). Do I still set VLAN 35?
Yes. For Internet-only service on Orange fiber, VLAN ID 35 is sufficient. Users without TV or VoIP have confirmed that VLAN 35 covers the Internet VLAN. [Elektroda, zdzlh, post #17100612]
Is there a premium all-in-one device that handles Orange FTTH requirements?
A Fritz!Box 7490 was reported to "do the trick." It is a pricier option but noted as working by a forum member. Confirm local firmware features before purchase. [Elektroda, haring, post #17104853]
My plan is 120 Mb/s. Will that change anything on the W9980?
A 120 Mb/s plan was mentioned in the thread, but throughput wasnt the blocker discussed. The main concern raised was configuration compatibility, not speed. Focus on the correct WAN mode and required tagging first. [Elektroda, zdzlh, post #17102797]
Does the W9980 have a dedicated WAN port?
It uses a combo LAN/WAN port. Flip the unit and you will see it labeled LAN/WAN. Enable Wireless Router Mode to use it as an Ethernet WAN. [Elektroda, jimasek, post #17100587]
. When set to Wireless Router Mode, the option to select VLAN ID disappears. I pitole. I will break down.
