Just got fully switched over from ADSL to VDSL today and installed an xDSL Master Filter, though after I completed the install, the modem was unable to synchronize. My phones however, all worked fine.
kernel: Line 0: VDSL G.993 started
kernel: Line 0: VDSL2 link down
And repeated indefinitely.
With the xDSL filter removed, the modem is able to synchronize fine.
If you'll excuse the crudeness of it, I quickly threw together a wiring diagram of sorts.
Any input on why it may not be working would be greatly appreciated.
