Nie, dziękuję Przekieruj mnie tamTL;DR: If INEA fiber on Światłowód Inwestycje will not work with your own router, start with VLAN 20; one user on 1000/300 Mb/s reported 920/280 Mb/s and said, "everything works without any problems." This FAQ is for users replacing the ZTE H3640 behind a ZTE F601 or Huawei ONT and needing stable WAN settings. [#20962342]
Why it matters: INEA deployments in different locations can use different WAN behavior, so the right setup can be VLAN 20, auto-detect, or passive packet capture before you change hardware.
| Setup path | Reported result | Notes |
|---|---|---|
| Manual WAN VLAN 20 | Worked on several Światłowód Inwestycje installs | Confirmed on Asus, TP-Link, Redmi, EdgeRouter cases |
| WAN on auto / no manual VLAN | Worked on at least one UDM-Pro install | Useful when manual VLAN trials fail |
| Passive capture with Wireshark / mirroring | Revealed live VLANs | Best when the ISP will not disclose settings |
| Reconnecting original ZTE router | Restored service in one unstable EdgeRouter case | Often gave a new IP afterward |
Key insight: There is no single universal INEA VLAN recipe in the thread. VLAN 20 solved most custom-router internet cases, but at least one user reported internet without a VLAN tag and another succeeded by leaving WAN on auto. [#21060363]
