Gentlemen, a question: I have recently set up a fibre optic cable from Inea on the infrastructure Światłowód Inwestycje (ONT ZTE router). I unplugged their router, connected my Ubiquiti EdgeRouter-X-5 instead. I set VLAN 20 and the Internet is laughing. But until... Every few days the internet shuts down. Turning on and plugging their ZTE Router back in for a while (the Internet on their router is there) and reconnecting to my EdgeRouter solves the issue. After such an operation I get a new IP address (of course this is the public address of their central Poznań address, I have some private one assigned). And so every couple of days... Cloning the MAC address on the WAN port in the EdgeRouter does not help. The router won't switch to Bridge mode and it's impossible to do it yourself (although I'd really rather not use it at all). Due to the inability to get a landline password from them - I gave up the phone, left the internet alone. Unfortunately it's been 14 days now so I won't terminate the contract completely. Do you have any ideas? Thank you in advance.

Hello everyone,

I recently got a fibre optic cable and took internet from INEA 600 as they were the only ones offering a symmetrical connection.

I was searching the internet for settings for INEA and came across this thread. The first thing I did was to start with VLANs but none of them worked. It turned out that on my UDM-Pro, just leave everything on auto and it works!

Greetings everyone. I hope this helps someone.

Topic summary

The discussion focuses on configuring VLAN settings for Internet access on INEA's fiber optic service using ZTE ZXHN F601 ONT and ZTE ZXHN H3640 router. Users report that the Internet VLAN is typically VLAN 20, not VLAN 60 as initially assumed, with VLAN 20 required on the WAN interface for proper IP assignment and connectivity. VoIP and IPTV services use different VLANs, commonly VLAN 20 for VoIP and VLAN 350 for IPTV, but credentials for VoIP (SIP login and password) are not provided by INEA, limiting third-party VoIP device integration. Attempts to enable bridge mode on the ONT/router are generally unsupported or require INEA intervention. Some users successfully identified VLANs by capturing traffic with Wireshark or using port mirroring on switches. Cloning the MAC address is sometimes used but not always necessary. Alternative routers like Ubiquiti EdgeRouter-X and Asus GTAX6000 have been tested with VLAN 20 settings, with mixed stability results. The discussion also highlights regional VLAN variations and the challenge of extracting VoIP credentials from the ZTE H3640 router. Overall, VLAN 20 is the key setting for Internet on INEA's fiber infrastructure, with additional VLANs for VoIP and IPTV, but full configuration details and credentials remain restricted by the ISP.

FAQ

TL;DR: 92 % real throughput (920 Mbps on a 1 Gbps plan) and 4-6 ms ping are reported; "VLAN 20 worked for me" [Elektroda, prokimac13, post #20962342] Most INEA fibre lines accept DHCP on VLAN 20; set, reboot, connect.

Why it matters: Knowing the correct VLAN saves hours of trial-and-error and lets you keep your own router.

Quick Facts

• Internet VLAN on Światłowód Inwestycje: 20 in most regions [Elektroda, #20963306; #20968015]
• IPTV usually VLAN 350; some areas run data untagged and VoIP on 20 [Elektroda, sawik_7BF, post #21055438]
• Reported speed: 920 / 280 Mbps on 1000 / 300 tariff (92 % / 93 %) [Elektroda, 20962342]
• Typical ping inside Poland: 4-6 ms on WireGuard tunnel [Elektroda, 20962342]
• H3640 router draws ≈3× more power than Redmi AX5 [Elektroda, dipalomeri, post #20968015]

1. What VLAN ID carries the Internet on ZTE ZXHN F601/H3640 with INEA?

In most Światłowód Inwestycje deployments the Internet sits on VLAN 20. Users in Warsaw-Brwinów, Zgierz and several Poznań suburbs confirmed instant DHCP after tagging 20 [Elektroda, #20963306; #20968015; #20941294].

2. Does every INEA area use VLAN 20?

No. A Poznań-Rataje trace showed untagged Internet frames, VoIP on 20 and IPTV on 350 [Elektroda, 21055438] Always verify before hard-coding a value.

3. Do I need to clone the original router’s MAC address?

Cloning is optional. Multiple users got addresses without cloning – “worked without the clone” [Elektroda, Breethagh, post #20963306] – though one EdgeRouter owner still renews leases by briefly reconnecting the ZTE [Elektroda, cichyfcb, post #21320463]

4. How can I discover my own VLAN IDs?

Sniff the traffic from the stock router.

Power the ZTE router alone, link PC → ZTE WAN.
Start Wireshark; capture boot traffic.
Read 802.1Q tags in the DHCP Discover frame.
This three-step trace revealed VLAN 20 for several users [Elektroda, 20963294]

5. Which VLANs carry VoIP and IPTV?

Typical mapping: VoIP on 20, IPTV on 350. One capture showed that set [Elektroda, 21055438] Edge cases exist where VoIP shares VLAN 20 or needs untagged frames; credentials are still required.

6. Can I pull SIP credentials from the H3640?

Not easily. Passwords reside in the router and download via TR-069/TR-068; INEA refuses to disclose them [Elektroda, #21055438; #21000637]. Without root access you cannot register an external ATA or soft-phone.

7. My EdgeRouter loses WAN every few days—what fixes it?

INEA may drop DHCP leases bound to the ONT’s port. Schedule a DHCP renew every 23 h or script a PPPoE-style reconnect. One user restores service by briefly inserting the ZTE, then swapping back [Elektroda, 21320463]

8. Does INEA enable full bridge mode on the H3640?

Official support says “we do not have the option” [Elektroda, 20863655] Field technicians claim they can request it internally, but no forum member reported success [Elektroda, 20907675]

9. What speeds and latency can I expect after replacing the router?

With VLAN 20 set, users logged 920 Mbps down, 280 Mbps up and 4-6 ms domestic ping on third-party hardware like TP-Link AX55 and Archer C7 [Elektroda, #20962342; #20907675].

10. Which third-party routers work well with INEA fibre?

Confirmed models include TP-Link AX55, TP-Link Archer C7, Redmi AX5, Asus GT-AX6000 and Ubiquiti EdgeRouter-X; a UniFi UDM-Pro functioned with all settings on auto [Elektroda, #20939576; #20907675; #20968015; #20963306; #21353167].

11. How much energy can I save by ditching the H3640?

A user noted the H3640 consumes roughly three times the power of a Redmi AX5. Assuming 12 W vs 4 W, savings reach ≈70 kWh yearly, about €14 at €0.20 / kWh [Elektroda, 20968015]

12. What’s an edge-case that breaks connectivity?

VLAN 60, listed by SAT-Kurier, fails on Światłowód Inwestycje installs and blocks DHCP entirely [Elektroda, twisteros2, post #20863595]

13. How do I mirror traffic without two NICs?

Use a managed switch with Port Mirroring; point the mirror to a PC running Wireshark [Elektroda, kokosoft, post #21011382]

14. Can I get a public IPv4 from INEA?

Yes. INEA sells variable public IP add-ons. One subscriber activated the option and ran WireGuard successfully [Elektroda, 20962342]

15. What DNS servers should I hand out via DHCP?

Supplying INEA’s own DNS (picked from the ZTE’s DHCP list) solved IPTV issues for at least one user [Elektroda, 20863655]
