Update: the DrayTek is well and truly fubar. Its internal web management server is now failing to serve up some of its own content (like a CSS style sheet). Rebooting doesn't help. Despite this, it's still routing packets to the Internet. Mostly. Sometimes.
So yeah, Netgear was dying after six months. DrayTek lasted two years. Who knows, maybe the crappy signal quality of the line (even our voice calls are full of static now) hastened its demise. Hard to say.
I seem to have AT&T scheduled for Tuesday AM. We're going to upgrade to UVerse proprietary DSL, and I'm hoping they can also debug the line noise.
Sigh.
