My Zyxel 642R appears to be dying; can't deal with a 10Mbps line.
Recommendation from my ISP is a Zyxel VMG 4005-B50B.

I'm wondering if others have different recommendations.
Also wondering what the difference between a B50B and a B50A are;
it's not obvious to me looking at specs, other than the B50A supports
G.993.1 VDSL which shouldn't be important I don't think.

Thanks,

Gary
