ONT Leox Netgear Nighthawk RS700 802.1Q

Hello

I need your help to solve the problem of lack of 802.1Q in RS700 which is necessary to replace ISP’s (T-mobile PL) Sagemcom Fast 5670 TMPL. The Sagemcom’s soft lets me change the wifi name and on/off DHCP only. No bridge mode or more sophisticated features. No fixed IP from ISP.

ISP’s requirements:

Router with 802.1Q

Internet VLAN ID - 35

Connection type - PPPoE

User name - 48998XXXXXX

Password – YYYYYYYYYY

My gear:

ONT Leox LXT-010H-D

https://leolabs.pl/ont-leox-lxt-010h-d.html

Latest firmare (3.3.2L10), factory settings restored.

And the Netgear Nighthawk RS700 with 1.0.7.96 firmare.

I get O5 on ONT, the PON light is green. The data entered into the router, looks ok.

But when the router is connected to the ONT, its LAN light is blinking red and the router’s INTERNET light is solid amber what means that the cable is plugged in, but there is no internet connection.

I have two Netgear switches with 802.1Q: GS105 and GS305 if it helps.

Is there any possibility to make it work?
