@TPint I really can't say what you should do - it is your ISP who should know what you have to configure. VR1200v has all means to configure a second internet connection with the parameters described...

@TPint Except the 2x FXS additional ports on the back (for voice) and the up-to-date FW (for VR1200v), the directions I posted are still valid.

@TPint You can get the latest firmware for your device from here. Update to Archer_VR1200_v1_1.0.0 0.8.0 v600e.0 Build 220711 Rel.67869n version and check again. From FW release notes it's compatible...

@TPint Try this guide and check if it helps in your case.

@alby1976 You can try lowering the RE650 coverage as well:

@6502 Use this guide (Case 2) for configuring the virtual server on port 80.
